Microplastics Could Be Changing Earth’s Climate, Reveals New Study

A Penn State University study published in Environmental Science & Technology: Air reveals that airborne microplastics may influence the climate by affecting cloud structures and weather patterns. The study found that microplastics act as ice nucleating agents in clouds, potentially altering precipitation. Professor Miriam Freedman highlights the need for more research into how these particles interact within atmospheric systems to better understand their effects on climate.

At UN climate talks, nations big and small get chance to bear witness to climate change

BAKU, Azerbaijan — When more than two dozen world leaders deliver remarks at the United Nations' annual climate conference on Wednesday, many have detailed their nations' firsthand experience with the catastrophic weather that has come with climate change. “Over the past year, catastrophic floods in Spain, Bosnia and Herzegovina as well as well as in southern Croatia have shown the devastating impact of rising temperatures,” said Croatia's prime minister, Andrej Plenkovic. “The Mediterranean, one of the most vulnerable regions, calls for urgent action.” The Greek prime minister said Europe and the world needs to be “more honest” about the trade-offs needed to keep global temperatures down. “We need to ask hard questions about a path that goes very fast, at the expense of our competitiveness, and a path that goes some much slower, but allows our industry to adapt and to thrive,” he said. His nation this summer was hammered by successive heat waves after three years of below-average rainfall. In Greece, the misery included water shortages, dried-up lakes and the death of wild horses. Other speakers on the list include Pakistan Prime Minister Shehbaz Sharif, whose nation has seen deadly flooding this year from monsoon rains that scientists say have become heavier with climate change. Just two years ago, more than 1,700 people died in widespread flooding. Pakistan has also suffered from dangerous heat, with thousands of people hospitalized with heatstroke this spring as temperatures soared to 47 degrees Celsius. Also on the list of speakers Wednesday is Bahamas Prime Minister Philip Edward Davis. Like many other countries in the Global South, the Bahamas has piled up debt from warming-connected weather disasters it did little to cause, including Hurricanes Dorian in 2019 and Matthew in 2016. Leaders have been seeking help and money from the Global North and oil companies. Early on Wednesday, ministers and officials from African nations called for initiatives to advance green development on the continent and strengthen resilience to extreme weather events — from floods to droughts — across the region. Plenty of big names and powerful countries are noticeably absent from COP29 this year. That includes the 13 largest carbon dioxide-polluting countries — a group responsible for more than than 70% of the heat-trapping gases emitted last year — were missing. The world’s biggest polluters and strongest economies — China and the United States — didn't send their No. 1s. Neither did India and Indonesia. But U.K. Prime Minister Keir Starmer was there, and he announced an 81% emissions reduction target on 1990 levels by 2035, in line with the Paris Agreement goal to limit warming to 1.5 degrees Celsius above pre-industrial times. That’s up from the 78% the U.K. had already pledged. The main focus of this year’s talks is climate finance — wealthier nations compensating poor countries for damages from climate change’s weather extremes, helping them pay to transition their economies away from fossil fuels and helping them with adaptation.

US will back South Asia climate diplomacy: White House official

AFTER Pakistan floated the idea of ‘climate diplomacy’ to tackle cross-border pollution in light of smog which has engulfed vast tracts of India and Pakistan, a US official indicated on the sidelines of COP29 that the White House may throw its weight behind any initiative taken in this regard.

Last month, Punjab Chief Minister Maryam Nawaz expressed her government’s intention to approach India to jointly counter the air pollution, which mostly comes from vehicular and industrial emissions, and is exacerbated in winter due to stubble burning.

Talking to Dawn on the sidelines of COP29 in Baku, Ali Zaidi — national climate adviser to the Biden administration — said the US was “100 per cent supportive” of partnership-based approaches to tackle problems that cannot be solved in isolation.

“In the US, we have this thing called the ‘good neighbour rule’, which governs smog. It actually was developed when we witnessed exactly this phenomenon in the US. So you know when it comes to cross-border pollution and cross-border issues, we are 100pc suportive of partnership-based approaches to tackle problems that cannot be solved on their own,” he said in response to a question about smog, which has made life unbearable for millions in Pakistan.

The White House official said the US was already active in the Hindu Kush — often referred to as ‘The Third Pole’ for housing the most glaciers in the world outside the polar regions — to better coordinate the mitigation response, because environmental impacts from glaciers do not isolate themselves to one jurisdiction.

“I think the regional solutions are a necessary complement to this sort of multilateral dialogue,” he said, referring to the COP summit.

The adviser said regional cooperation among relevant parties to address climate change would have more impact than putting “another ornament on a 1,000-page document (COP)”.

In response to a question about the failure of the world to help Pakistan after the 2022 floods caused damages to the tune of $30 billion, he said the global community needed to reinvent its approach to rebuilding from disasters, particularly by investing in pre-disaster mitigation.

According to the White House official, the US took a really long time to reengineer its thinking domestically in terms of building resilience into the recovery.

He favoured approaches that ran “consistent with the financial position” of states that needed to do rebuilding, saying there was a need to mobilise more countries to move more capital to help with adaptation and mitigation in these vulnerable countries.

In response to a question about the loan-laden climate finance framework, he said, “If you are targeting projects that have very clear cash flow and a strong counterparty then debt works just fine.”

He agreed some concessionary capital did need to come in depending on the technological aspect, the richness of the resources and the maturity of the market, while referring to India’s solar projects.

Vulnerable areas need significant grant-based aid, but there is still a need to figure out how to monetise risk reduction associated with adaptation finance and that’s why it was difficult to do. These places are going to soak up more grant-based finance, he said.

Speaking about the Trump-led US administration all set to take over from the Biden administration, he appeared optimistic, saying the states in the US will figure out how to provide the policy support even if the federal government stopped being part of it. About the US, he said it should remain part of the dialogue and be the author of the roadmap that will govern the contours of climate finance for decades to come.
