The Asian Development Bank (ADB) has approved a $500 million policy-based loan to support climate change and disaster risk reduction and resilience in Pakistan, a statement from the bank said on Tuesday.

In 2022, massive floods triggered by climate change devastated several parts of Pakistan, killing 1,700 people, washing away swathes of agricultural land, affecting 33 million people, and incurring losses worth $30 billion, according to government estimates.

The Climate and Disaster Resilience Enhancement Programme (CDREP) will strengthen Pakistan’s institutional capacity for planning, preparedness, and response; increase inclusive investment in disaster risk reduction and climate resilience; and support the scale-up of disaster risk financing using a risk-layered approach, the statement said.

“Pakistan is one of the most vulnerable countries to climate change and disasters triggered by natural hazards in Asia and the Pacific. Average losses from disaster events exceed $2 billion per year.

“Women and other vulnerable groups are disproportionately affected by climate change and disaster events,” the statement said.

“This programme builds on ADB’s longstanding work in Pakistan to understand and reduce climate and disaster risks and support effective disaster response,” said ADB Director General for Central and West Asia Yevgeniy Zhukov.

“We are proud to support an integrated and comprehensive approach to climate and disaster risk management, including a portfolio of disaster risk financing instruments for timely and adequate funding for disaster response,” Zhukov was quoted as saying in the statement.

It added that the programme supports the enhanced capacity for disaster risk mapping and modelling for investment and development decisions, as well as enhances coordination for disaster monitoring and response. It also supports enhanced planning and prioritisation of gender-sensitive and resilient public investments, including integrated flood risk management and nature-based solutions.

The programme supports the mobilisation of climate finance from public and private sources. This includes the issuance of a domestic green sukuk (Islamic bond).

A key innovation of the program is the use of ADB’s Contingent Disaster Financing option for the first time in the Central and West Asia region. This will provide quick disbursing budget support in the event of a disaster.

The programme will also support the establishment of a solidarity fund to facilitate the uptake of risk transfer solutions such as agriculture insurance, while also backing shock-responsive social protection to deliver cash assistance in the event of a disaster, the statement added.

ADB has also approved a technical assistance grant of $1 million to support the implementation of the programme.

Tuesday’s announcement comes after the ADB announced in September that it will provide $2 billion in annual assistance to Pakistan over the next three years to support infrastructure development and climate-resilient initiatives.

A report by the Policy and Strategy Committee (PSC) and the Oversight Board on Post-Flood Reconstruction Activities showed last month that the country had only received $10.9bn from international development partners out of the total estimated loss for post-flood reconstruction work, leaving a $19.1bn shortfall that has halted the rehabilitation of flood-affected communities in three provinces.

ADB’s country partnership strategy, 2021–2025, for Pakistan, focuses on three priorities: improving economic management, building resilience, and boosting competitiveness and private sector development.

As of December 31, 2023, the bank has committed 755 public sector loans, grants, and technical assistance totalling $41.4bn to Pakistan. ADB’s current sovereign portfolio in Pakistan includes 55 loans and four grants worth $10.11bn.

Cumulative sovereign and nonsovereign loan and grant disbursements to Pakistan amount to $31.76bn.

These loans were financed by regular and concessional ordinary capital resources, the Asian Development Fund, and other special funds.

Carbon cuts 'miles short' of 2030 goal: UN https://thenewshub.in/2024/10/28/carbon-cuts-miles-short-of-2030-goal-un/ https://thenewshub.in/2024/10/28/carbon-cuts-miles-short-of-2030-goal-un/?noamp=mobile#respond Mon, 28 Oct 2024 10:24:09 +0000 https://thenewshub.in/2024/10/28/carbon-cuts-miles-short-of-2030-goal-un/

Carbon cuts ‘miles short’ of 2030 goal: UN

Greenhouse gas concentrations in the atmosphere reached new record highs in 2023, the UN warned on Monday, with countries falling “miles short” of what is needed to curb devastating global warming.
Levels of the three main greenhouse gases — heat-trapping carbon dioxide, methane and nitrous oxide — all increased yet again last year, said the World Meteorological Organization, the United Nation’s weather and climate agency.
Carbon dioxide was accumulating in the atmosphere faster than ever, up more than 10 percent in two decades, it added.
And a separate report by UN climate change found that barely a dent is being made in the 43 percent emissions cut needed by 2030 to avert the worst of global warming.
Action as it stands would only lead to a 2.6 percent reduction this decade from 2019 levels.
“The report’s findings are stark but not surprising — current national climate plans fall miles short of what’s needed to stop global heating from crippling every economy, and wrecking billions of lives and livelihoods across every country,” said UN climate chief Simon Stiell.
The two reports come just weeks before the United Nations COP29 climate summit in Azerbaijan, and as nations prepare to submit updated national climate plans in early 2025.
“Bolder” plans to slash the pollution that drives warming will now have to be drawn up, Stiell said, calling for the end of “the era of inadequacy”.
– ‘Alarm bells’ –
Under the 2015 Paris Agreement, countries agreed to cap global warming at “well below” two degrees Celsius above average levels measured between 1850 and 1900 — and 1.5C if possible.
But so far their actions have failed to meet that challenge.
Existing national commitments would see 51.5 billion tonnes of CO2 and its equivalent in other greenhouse gases emitted in 2030 — levels that would “guarantee a human and economic trainwreck for every country, without exception,” Stiell said.
As long as emissions continue, greenhouse gases will keep accumulating in the atmosphere, raising global temperatures, WMO said.
Last year, global temperatures on land and sea were the highest in records dating as far back as 1850, it added.
WMO chief Celeste Saulo said the world was “clearly off track” to meet the Paris Agreement goal, adding that record greenhouse gas concentrations “should set alarm bells ringing among decision-makers”.
“CO2 is accumulating in the atmosphere faster than at any time during human existence,” the report said, adding that the current atmospheric CO2 level was 51 percent above that of the pre-industrial era.
– Sea levels 65 feet higher –
The last time the Earth experienced a comparable concentration of CO2 was three to five million years ago, when the temperature was two to three Centigrade warmer and the sea level was 10 to 20 metres (65 feet) higher than now, it said.
Given how long CO2 lasts in the atmosphere, current temperature levels will continue for decades, even if emissions rapidly shrink to net zero.
In 2023, CO2 concentrations were at 420 parts per million (ppm), methane at 1,934 parts per billion, and nitrous oxide at 336 parts per billion.
CO2 accounts for about 64 percent of the warming effect on the climate.
Its annual increase of 2.3 ppm marked the 12th consecutive year with an increase greater than two ppm — a streak caused by “historically large fossil fuel CO2 emissions in the 2010s and 2020s”, the report said.
Just under half of CO2 emissions remain in the atmosphere, while the rest are absorbed by the ocean and land ecosystems.
Climate change itself could soon “cause ecosystems to become larger sources of greenhouse gases”, WMO deputy chief Ko Barret warned.
“Wildfires could release more carbon emissions into the atmosphere, whilst the warmer ocean might absorb less CO2. Consequently, more CO2 could stay in the atmosphere to accelerate global warming.
“These climate feedbacks are critical concerns to human society.”

Pakistan wants to diversify its financing base: Finance Minister https://thenewshub.in/2024/10/27/pakistan-wants-to-diversify-its-financing-base-finance-minister/ https://thenewshub.in/2024/10/27/pakistan-wants-to-diversify-its-financing-base-finance-minister/?noamp=mobile#respond Sun, 27 Oct 2024 07:05:28 +0000 https://thenewshub.in/2024/10/27/pakistan-wants-to-diversify-its-financing-base-finance-minister/

Minister for Finance Muhammad Aurangzeb has invited Asian Infrastructure Investment Bank to provide support in terms of program loan for dealing with the impacts of climate change and disaster preparedness.

He was talking to President of the Bank Jin Liqun in Washington.

The Minister also invited the Bank to invest in N-5 (GT Road) reconstruction project.

He acknowledged the Bank’s support to Pakistan, particularly in dealing with the aftermath of the devastating floods of 2022.

The Finance Minister mentioned his visit to China where he interacted with the management of Peoples Bank of China.

He said Pakistan wants to diversify its financing base and explore the possibility of issuing a panda bond with partial credit guarantee of AIIB.

Muhammad Aurangzeb said enlisting AIIB as an anchor to support the process would send out a strong signal to the market.

He expressed satisfaction over the progress of AIIB projects in Pakistan and emphasized further efforts to improve the disbursement of ongoing projects.

He Invited the President to visit Pakistan which he accepted.

World already 'paying terrible price' for climate inaction: Guterres https://thenewshub.in/2024/10/24/world-already-paying-terrible-price-for-climate-inaction-guterres/ https://thenewshub.in/2024/10/24/world-already-paying-terrible-price-for-climate-inaction-guterres/?noamp=mobile#respond Thu, 24 Oct 2024 16:44:41 +0000 https://thenewshub.in/2024/10/24/world-already-paying-terrible-price-for-climate-inaction-guterres/

Humanity is ‘paying a terrible price’ for inaction on global warming, with time running out to correct the course and avoid climate disaster, UN Secretary General Antonio Guterres said Thursday.
A new report by the UN Environment Programme (UNEP) says the next decade is critical in the fight against climate change or any hope of limiting global warming to 1.5C will be lost.
The current pace of climate action would result in a catastrophic 3.1 degrees Celsius of warming this century, UNEP said in its latest Emissions Gap report.
And even if all existing pledges to cut emissions were enacted as promised, global temperatures would soar 2.6C above pre-industrial levels — a still devastating scenario for humanity.
“Either leaders bridge the emissions gap, or we plunge headlong into climate disaster, with the poorest and most vulnerable suffering the most,” said Guterres.
“Around the world, people are paying a terrible price.”
The call to action follows a streak of destructive and deadly extreme weather and comes in a year expected to be the hottest in recorded history.
The world’s poorest have been particularly hard hit, with typhoons and heatwaves in Asia and the Caribbean, floods in Africa, and droughts and wildfires in Latin America.
Nations meeting at the COP29 climate summit next month in Azerbaijan hope to agree on increasing finance for the developing world to cope with climate change.
– ‘Out of time’ –
UNEP’s latest projections blow well past 1.5C, which nations agreed in Paris in 2015 was the safest bet to minimise the worst consequences of a warming planet.
That goal was “still technically possible”, UNEP said — but only with enormous reductions by 2035 in heat-trapping gases caused primarily by burning fossil fuels.
Rather than declining, emissions are still rising, hitting a new record high last year.
Guterres said the world was “playing with fire”.
“But there can be no more playing for time. We’re out of time,” he said.
Keeping 1.5C on track would require a collective effort “only ever seen ever seen following a global conflict”, UNEP said.
Without pulling together “on a scale and pace never seen before… the 1.5C goal will soon be dead,” said UNEP executive director Inger Andersen.
To have a hope of meeting 1.5C, emissions must be slashed 42 percent by 2030 and 57 percent by 2035, UNEP said.
The existing suite of climate commitments — including those contingent on outside financial help — would only cut expected 2030 emissions by 10 percent if implemented as promised.
“These reports are an historical litany of negligence from the world’s leaders to tackle the climate crisis with the urgency it demands, but it’s not too late to take corrective action,” said Tracy Carty from Greenpeace International.
– ‘Bridge the gap’ –
UNEP said advances in solar and wind, two proven and cost-effective technologies, could deliver a steep fall in emissions but investment in such carbon-cutting solutions needed to rise six-fold to meet 1.5C.
Guterres said wealthy nations of the G20 must lead the way.
“Either leaders bridge the emissions gap, or we plunge headlong into climate disaster,” he said.
The world’s 20 largest economies were responsible for nearly 80 percent of global emissions in 2023. The bottom 47 countries accounted for three percent.
The United States was historically the biggest polluter, accounting for 20 percent of global emissions since 1850, when the burning of fossil fuels for energy began in earnest.
The European Union and China accounted for 12 percent each, UNEP said.
A breach of 1.5C is increasingly being seen as inevitable by scientists and policymakers.
But a recent study found that even temporarily exceeding 1.5C before bringing warming back down — a scenario known as an ‘overshoot’ — could cause irreversible consequences for the planet.

India leading global climate action despite contributing marginally to climate change: Modi https://thenewshub.in/2024/10/21/india-leading-global-climate-action-despite-contributing-marginally-to-climate-change-modi/ https://thenewshub.in/2024/10/21/india-leading-global-climate-action-despite-contributing-marginally-to-climate-change-modi/?noamp=mobile#respond Mon, 21 Oct 2024 16:27:13 +0000 https://thenewshub.in/2024/10/21/india-leading-global-climate-action-despite-contributing-marginally-to-climate-change-modi/

New Delhi: India is leading the global movement against climate change despite contributing marginally to the problem, Prime Minister Narendra Modi said on Monday, citing its plans for growth focused on “stability, sustainability and solutions.”

The greening of industries as well as green jobs are the future, Modi said, adding that green transition is the focus of India’s growth trajectory led by schemes related to electric vehicles, green hydrogen, ethanol blending and rooftop solar installations, among other things.

Modi said India’s push for electric vehicles, the PM Surya Ghar Muft Bijli Yojana and solar pump schemes for agriculture, ethanol blending, large wind energy farms, LED lights, solar-powered airports and biogas plants reflect a strong commitment to a green future and green jobs.

Along with resolving domestic issues, India is also focused on addressing global concerns on climate change, the prime minister told the NDTV World Summit. 

He said that over the past decade, India has worked on numerous initiatives essential for tackling these challenges, including the International Solar Alliance, the Coalition for Disaster Resilient Infrastructure, the India-Middle East Economic Corridor, the Global Biofuel Alliance, as well as efforts in yoga, ayurveda, Mission Life and Mission Millets. “All these initiatives represent India’s commitment to finding solutions to the world’s pressing issues,” he said.

Modi also spoke about India’s growth in the technology sector, which led to democratization of services and financial inclusion in the country.

He praised the country’s digital public infrastructure, including platforms such as Aadhar, Digilocker, and ONDC, and hailed the success of the Unified Payment Interface (UPI) with over 500 million transactions daily.

India has provided a new model to the world by democratizing technology and highlighted the JAM trinity—Jan Dhan, Aadhaar and Mobile—which provides a robust system for faster and leakage-free service delivery, he added.

He also said the PM Gati Shakti platform for infrastructure projects had helped reduce construction in silos and changed the logistics ecosystem. 

Modi mentioned the launch of India AI Mission this year and laid emphasis on increasing the use of AI across sectors like healthcare, education and startups. “India is committed to delivering world-class AI solutions, and through platforms like Quad, we are taking significant initiatives to drive this forward,” he said.

Modi said AI also stood for “Aspirational India,” adding that the middle class, general citizens, enhancing the quality of life, and empowering small businesses, MSMEs (micro, small and medium enterprises), youth, and women are at the heart of the government’s policymaking process.

The prime minister pointed out the enthusiasm of experts like Mark Mobius, who advised global funds to invest at least 50% of their funds in India’s share market. “When such seasoned experts advocate for major investments in India, it sends a strong message about our potential.”

Noting the completion of 125 days of the third term of the government, Modi threw light on the work done in the country. He stated that 500,000 homes had installed rooftop solar plants under the PM Surya Ghar Muft Bijli Yojana, which provides free electricity to households.

He said India’s forex chest had risen to $700 billion. 

“Our goal of a Viksit Bharat by 2047 is not just a vision of the government but reflects the aspirations of 140 crore Indians. It’s no longer just a campaign for public participation, but a movement of national confidence,” Modi said.

On the topic of youth empowerment, Modi highlighted the government’s focus on education, skill development, research and employment. He said that the result of the efforts in the last 10 years are now visible and mentioned India’s highest improvement globally in research quality as reflected in the latest Times Higher Education ranking. 

He noted that the participation of Indian universities in international rankings has grown from 30 to over 100 in the past eight-nine years. The prime minister underlined that India’s presence in the QS World University Rankings has increased by more than 300% in the last 10 years while the number of patents and trademarks filed in India is also at an all-time high.

Can Diamond Dust Help Cool Earth? Exploring Costs and Geoengineering Risks https://thenewshub.in/2024/10/19/can-diamond-dust-help-cool-earth-exploring-costs-and-geoengineering-risks/ https://thenewshub.in/2024/10/19/can-diamond-dust-help-cool-earth-exploring-costs-and-geoengineering-risks/?noamp=mobile#respond Sat, 19 Oct 2024 16:04:07 +0000 https://thenewshub.in/2024/10/19/can-diamond-dust-help-cool-earth-exploring-costs-and-geoengineering-risks/

Injecting diamond dust into the atmosphere could potentially cool the planet by 1.6ºC, according to a recent study published in Geophysical Research Letters. Led by Sandro Vattioni, a climate scientist at ETH Zürich, the research explores whether diamonds, as opposed to commonly used materials like sulfur, could offer a safer and more effective method for stratospheric aerosol injection. This method is aimed at reflecting sunlight back into space to mitigate global warming.

Diamonds Versus Sulfur for Cooling

While sulfur has been studied as a cooling agent—largely inspired by volcanic eruptions that inject sulfur dioxide into the atmosphere—the material poses significant risks, including ozone depletion and acid rain. Diamonds, on the other hand, are chemically inert and would not contribute to these hazards. Vattioni and his team ran complex climate models to assess the impact of different materials. Diamonds stood out for their reflective properties and ability to remain aloft without clumping together.

The Steep Costs of Diamonds

Although diamonds could offer a promising solution, their cost is a major drawback. With synthetic diamond dust estimated to cost around $500,000 per ton, scaling up production to inject 5 million tons annually would demand an enormous financial commitment. According to Douglas MacMartin, an engineer at Cornell University, the cost of deploying diamond dust from 2035 to 2100 could reach $175 trillion. This price tag far exceeds the relatively inexpensive sulfur, which is readily available and much easier to disperse. MacMartin suggests that sulfur may still be the material of choice due to its lower cost and ease of use.

Debate Continues on Geoengineering

Geoengineering research, including the study of alternative materials like diamonds, remains a contentious topic. Critics like Daniel Cziczo, an atmospheric scientist at Purdue University, argue that the risks of unintended consequences outweigh the potential benefits. However, Shuchi Talati, executive director of the Alliance for Just Deliberation on Solar Geoengineering, emphasises that research is essential for understanding all possible options, especially for nations most vulnerable to climate change

Death risk found to rise due to adverse effects on health in wake of extreme rainfall events https://thenewshub.in/2024/10/12/death-risk-found-to-rise-due-to-adverse-effects-on-health-in-wake-of-extreme-rainfall-events/ https://thenewshub.in/2024/10/12/death-risk-found-to-rise-due-to-adverse-effects-on-health-in-wake-of-extreme-rainfall-events/?noamp=mobile#respond Sat, 12 Oct 2024 13:56:19 +0000 https://thenewshub.in/2024/10/12/death-risk-found-to-rise-due-to-adverse-effects-on-health-in-wake-of-extreme-rainfall-events/

NEW DELHI: Risk of death was found to rise in the wake of an extreme rainfall event, including death due to heart and lung conditions, according to a study. With climate change making short-term rainfall events more extreme and frequent, there is emerging evidence that suggests a compelling link between these events and their adverse effects on health, especially the spread of infectious diseases, researchers said based on a study of over 62,000 rainfall events across the globe.
The study by the team, including researchers from the German Research Center for Environmental Health, provides a global perspective of how extreme rainfall events can impact health, they said.
They looked at the data of daily deaths and rainfall from 645 locations from across 34 countries and regions, recorded from 1980 to 2020. A total of over 100 million deaths from any cause, and more than 31 million and 11.5 million deaths due to heart and lung conditions, respectively, were analysed.
A day of extreme rainfall, that could likely recur over the following five years, was linked with an eight per cent increase in deaths due to any cause over the 14 days following the extreme weather event.
Such an event was also related with a five per cent increase in cardiovascular deaths and a nearly 30 per cent increase in lung-related mortality in the fortnight following the rainfall.
“Daily rainfall intensity is associated with varying health effects, with extreme events linked to an increasing relative risk for all cause, cardiovascular, and respiratory mortality. The observed associations varied with local climate and urban infrastructure,” the authors wrote in the study published in the British Medical Journal.
Acknowledging the limitations of the research, the team said the study was observational and thus, could not draw cause-and-effect conclusions. Further, locations analysed were largely in east Asia, Europe, and North America, they added.
The findings, however, highlighted the need for coordinated public health strategies targeted at the health impacts of extreme rainfall, the authors said.
“This is especially important considering the well established trend of increasing short term rainfall intensity as a result of climate change,” they wrote.

Climate change made deadly Hurricane Helene more intense: study https://thenewshub.in/2024/10/10/climate-change-made-deadly-hurricane-helene-more-intense-study/ https://thenewshub.in/2024/10/10/climate-change-made-deadly-hurricane-helene-more-intense-study/?noamp=mobile#respond Thu, 10 Oct 2024 11:14:01 +0000 https://thenewshub.in/2024/10/10/climate-change-made-deadly-hurricane-helene-more-intense-study/

WASHINGTON: Hurricane Helene‘s torrential rain and powerful winds were made about 10 percent more intense due to climate change, according to a study published Wednesday by the World Weather Attribution (WWA) group.
Although a 10 percent increase “might seem relatively small… that small change in the hazard really leads to big change in impacts and damage,” said climate scientist Friederike Otto, who heads the research organization.
The study also found that fossil fuels — the primary cause of climate change — have made hurricanes like Helene 2.5 times more likely to occur.
In other words, storms of Helene’s magnitude were formerly anticipated once every 130 years, but now the probability is closer to once every 53 years, on average.
To conduct the study, researchers focused on three aspects of Hurricane Helene: precipitation, winds and the water temperature of the Gulf of Mexico — a key factor in its formation.
“All aspects of this event were amplified by climate change to different degrees,” Ben Clarke, a co-author of the study and researcher at Imperial College London, told a press conference.
“And we’ll see more of the same as the world continues to warm,” he continued.
The research by WWA, an international group of scientists and meteorologists who study the role of climate change in extreme weather events, comes as the southeastern US state of Florida prepares for the arrival of another major hurricane, Milton, just 10 days after it was hit by Helene.
Destruction
Helene made landfall in northwestern Florida on September 26 as a Category 4 hurricane with winds up to 140 mph (225 kph).
The storm then moved north, causing heavy rain and devastating floods in several states, including North Carolina, where it claimed the highest death toll.
The authors of the study emphasized that the risk posed by hurricanes has increased in scope beyond coastal areas.
Bernadette Woods Placky, chief meteorologist at NGO Climate Central, said Helene “had so much intensity” that it would take time for it to lose strength, but the “storm was moving fast… so it could go farther inland pretty quickly.”
This study utilized three methodologies to examine the three aspects of the storm, and was conducted by researchers from the US, the UK, Sweden and the Netherlands.
To study its rainfall, researchers used an approach based on both observation and climate models, depending on the two regions involved: one for coastal areas like Florida, and another for inland areas like the Appalachian mountains.
In both cases, the study found precipitation had increased by 10 percent because of global warming, which is currently at 1.3 degrees Celsius above pre-industrial levels.
To study Helene’s winds, scientists looked at hurricane data dating back as far as 1900.
They determined Helene’s winds were 11 percent stronger, or 13 mph (21 kph), as a result of climate change.
Lastly, the researchers examined the water temperature in the Gulf of Mexico, where Helene formed, finding it was around 2 degrees Celsius above normal.
This record temperature was made 200 to 500 times more likely due to climate change, the study asserts.
Warmer oceans release more water vapor, providing more energy for storms as they form.
“If humans continue to burn fossil fuels, the US will face even more destructive hurricanes,” Clarke warned in a statement.

Global warming. Disappearing plant and animal species. Fertile land turning to desert. Plastic in the oceans, on land, and the air we breathe.
These urgent environmental challenges will be in the spotlight over the next few months as the United Nations hosts four major sessions to address key threats to the planet.
Biodiversity
First up is a “Conference of the Parties” — a COP — dedicated to biodiversity being held in Cali, Colombia, from October 21 to November 1.
These are called every two years to debate how the world can cooperate to better protect the rich variety of plant and animal life in the natural world.
The COP16 isn’t expected to break new ground but will take stock of progress since the last summit secured historic assurances for biodiversity.
In 2022 in Montreal, nations agreed to place 30 percent of the planet under environmental protection by 2030 in a landmark pact aimed at arresting biodiversity loss and restoring ecosystems to health.
In Cali, countries will put forward national strategies to meet this global objective, and observers hope Colombia as host will provide a model for others to follow.
– Climate –
The world’s most important conference on climate change is this year being hosted by Azerbaijan, a former Soviet republic heavily dependent on oil and gas exports, from November 11 to 22.
While the last summit in Dubai in 2023 delivered a historic commitment to transition the world away from fossil fuels, supporting poorer countries with climate change will top this year’s agenda.
The summit, known as COP29, is expected to land a new agreement on “climate finance“: money from rich nations most responsible for global warming to developing countries vulnerable to climate change.
There isn’t an agreed figure yet, or even consensus on where the money should come from, who should receive it, and what form it could take.
But developing countries are pushing for much more than the $100 billion pledged in 2009. This was only reached for the first time in full in 2022.
The result of the US election, just six days before COP29 begins, could throw a last-minute curveball into the final negotiations, which have proved divisive so far.
It also remains to be seen how many world leaders travel to Baku, the capital on the Caspian Sea, with some expected to focus their energy on COP30 in Brazil next year.
Desertification
The least high profile of the three COPs, this session in Saudi Arabia addressing the loss of fertile land to desert is nonetheless critical.
Climate variation like droughts and human activities like overgrazing can result in desertification, a process mainly in dry areas where land degrades and becomes unproductive.
Experts hope the COP16 on desertification, scheduled to take place in Riyadh from December 2 to 13, can act as a turning point in addressing this problem.
“Discussions will focus on ways to restore 1.5 billion hectares of land by 2030, as well as putting in place agreements to manage the droughts that are already affecting many regions of the globe,” said Arona Diedhiou from the French National Research Institute for Sustainable Development.
– Plastic –
In 2022, some 175 nations agreed to fast-track negotiations toward a world-first treaty on plastic pollution, and the final session gets underway on November 25 in South Korea.
The treaty aims to marshal an international response to the plastic trash choking the environment, from oceans and rivers to mountains and sea ice.
Some nations want the treaty to restrict how much plastic can be made while others — particularly oil and gas producing countries that provide the raw materials to make plastic — want a focus on recycling.
Hellen Kahaso Dena, head of Greenpeace’s Pan-African Plastics Project, hopes that countries “will agree on a treaty that prioritises reducing plastic production”.
“There is no time to waste with approaches that will not solve the problem,” the activist told AFP.

NEW DELHI: Antarctica is turning green “dramatically”, with the trend accelerated by more than 30% in recent years, compared to the past three decades, a new study has found. Researchers found that vegetation cover across the Antarctic Peninsula increased more than tenfold from less than a square kilometre to almost 12 square kilometres between 1986 and 2021.
The researchers, including those at the University of Exeter, UK, used satellite data to estimate the “greening” rate of the Antarctic Peninsula in response to climate change.
“This recent acceleration in the rate of change in vegetation cover (2016-2021) coincides with a marked decrease in sea-ice extent in Antarctica over the same period,” the authors wrote in the study published in the journal Nature Geoscience.
The study provides evidence that a widespread greening trend, across the Antarctic Peninsula, is under way and accelerating, they said.
Antarctica has been shown to be warming faster than the global average, with extreme heat events becoming more common.
“The plants we find on the Antarctic Peninsula -mostly mosses – grow in perhaps the harshest conditions on Earth,” corresponding author Thomas Roland, University of Exeter, said.
While only a tiny fraction of the landscape -still largely dominated by snow, ice and rock -is colonised by plant life, that tiny fraction has grown “dramatically”, showing that even this vast and isolated ‘wilderness’ is affected by human-caused climate change, Roland said.
Corresponding author Oliver Bartlett, University of Hertfordshire, UK, said that as the climate warms and these plant ecosystems establish themselves more, it is likely that the greening will increase.
“Soil in Antarctica is mostly poor or non-existent, but this increase in plant life will add organic matter, and facilitate soil formation — potentially paving the way for other plants to grow,” Bartlett said.
Calling for further research to look into the processes that are driving the greening trend, the researchers said that the study raised serious concerns about the future of Antarctica.
“The sensitivity of the Antarctic Peninsula’s vegetation to climate change is now clear and, under future (human-caused) warming, we could see fundamental changes to the biology and landscape of this iconic and vulnerable region,” Roland said.
“In order to protect Antarctica, we must understand these changes and identify precisely what is causing them,” he added.
