Colder weather boosted heating fuels and a surge in electricity demand from data centres and crypto mining lifted US greenhouse gas emissions by 2.4% last year, with coal up 13% despite solar growth; higher natural-gas prices spurred fuel switching, while transport emissions stayed roughly flat thanks to more hybrids and EVs, and Trump-era policies are viewed as having little immediate impact.
At the UN Climate Summit, most countries committed to accelerating efforts to reduce greenhouse gases, while the US notably stayed away, highlighting its isolation on climate policy amid global efforts.
The Biden-era EPA policies aimed at reducing greenhouse gas emissions and promoting electric vehicles are projected to lower future gasoline prices and create jobs, but the Trump administration's proposed rollback could lead to higher gas prices and significant job losses, according to the agency's own analysis.
A new study predicts the Arctic Ocean could experience its first ice-free day as early as 2027, highlighting the rapid melting of Arctic sea ice due to climate change. Despite varying projections, all models indicate this milestone will occur by the 2030s, driven by greenhouse gas emissions. The loss of sea ice, crucial for regulating global temperatures and marine habitats, underscores the urgent need for emission reductions to delay this environmental shift.
A new study predicts the Arctic Ocean could experience its first ice-free day before 2030 due to rapid sea ice loss, a significant shift from previous projections. The Arctic has lost half of its late summer sea ice since the 1980s, and models suggest this trend could lead to an ice-free Arctic within the next three to six years. The loss of sea ice, exacerbated by the Albedo effect, could accelerate climate change and trigger extreme weather events. Reducing greenhouse gas emissions may delay but not prevent this outcome, impacting ecosystems and communities in the region.
A new study predicts the Arctic Ocean could experience its first ice-free day as early as 2027, due to rapid sea ice melting driven by climate change. The study, published in Nature Communications, suggests this milestone could occur within nine to 20 years regardless of greenhouse gas emission changes, though drastic emission cuts could delay it. The loss of sea ice, which plays a crucial role in regulating global temperatures and marine habitats, highlights the significant impact of human-induced climate change on the Arctic environment.
The International Court of Justice (ICJ) in The Hague is hearing a pivotal case involving nearly 100 countries, led by Vanuatu, to clarify the legal responsibilities of governments in combating climate change and addressing damages from rising temperatures. Although the court's decision will not be legally binding, it could influence global climate change lawsuits. The case, initiated by law students in Fiji and supported by Vanuatu, seeks to establish international legal obligations for climate action and could impact financial compensation claims by small island states against developed nations for historical emissions. The hearings will conclude in December, with a decision expected in 2025.
At COP29, a contentious climate proposal suggests wealthy nations contribute $250 billion annually to support poorer countries, but uncertainties remain about the distribution of funds, especially with potential policy shifts in the U.S. under a new Trump administration. Despite last year's commitments to reduce fossil fuel reliance, progress has stalled, and some developing nations are reluctantly considering accepting lower funding offers than desired. Meanwhile, a coalition excluding the U.S. plans to set ambitious greenhouse gas reduction targets by 2035.
At the COP29 climate summit in Baku, world leaders face the challenge of rising greenhouse gas emissions, despite the need to reduce them to meet Paris Agreement targets. The recent U.S. presidential election outcome threatens to derail progress, with the U.S. potentially withdrawing from climate commitments. While emissions continue to rise, the rate of increase is slowing, and renewable energy sources like wind and solar are gaining traction. However, fossil fuel consumption remains high, particularly in developing countries, complicating efforts to curb emissions. The conference struggles with setting an agenda, highlighting the fragile and slow progress in addressing climate change.
At the Cop29 UN climate summit, UN Secretary-General António Guterres described 2023 as "a masterclass in human destruction" due to climate change-induced extreme weather. The summit, attended by leaders from nearly 200 countries, focuses on raising funds to combat climate change, with developing nations seeking $1 trillion annually by 2035. The re-election of climate skeptic Donald Trump as US President casts a shadow over the talks. UK leader Keir Starmer announced ambitious plans to cut emissions by 81% by 2035, emphasizing economic opportunities in the green transition. Meanwhile, Azerbaijan's President Ilham Aliyev defended his country's continued fossil fuel extraction, highlighting the tension between economic interests and climate action.
The 29th United Nations Climate Change Conference (COP29) is underway in Baku, focusing on climate finance for developing countries and addressing the global climate crisis. Despite reductions in emissions by major historical emitters like the EU, US, and UK, global CO2 emissions have risen, with China contributing significantly. The world has surpassed 1.5°C of warming, and 2024 is projected to be the hottest year on record. While renewable energy use is increasing, fossil fuels remain dominant. The IPCC outlines scenarios predicting temperature rises based on emission levels, with the most severe scenario projecting a 4.4°C increase by 2100.
New research indicates that climate change is lengthening days by causing glaciers and polar ice sheets to melt, which redistributes water closer to the equator and slows Earth's rotation. This effect has accelerated since 2000 and could have significant implications for technologies reliant on precise timing, such as navigation and data centers.
Hawaiʻi has agreed to a landmark settlement in a youth-led climate lawsuit, committing to create a comprehensive plan to reduce greenhouse gas emissions from its transportation sector. The young plaintiffs argued that the state's transportation policies violated their constitutional right to a clean environment. The settlement includes developing a 20-year roadmap with interim goals, tracking emissions, and establishing a youth advisory council. This case marks the first youth-led climate lawsuit in the U.S. to reach a settlement.
The Biden-Harris Administration announced nearly $900 million in funding through the EPA's Clean School Bus Program to replace over 3,400 diesel school buses with cleaner alternatives, primarily electric, across 530 districts. This initiative aims to improve air quality, reduce greenhouse gas emissions, and support American manufacturing, particularly benefiting low-income, rural, and Tribal communities.
The Biden-Harris Administration has announced new principles for high-integrity voluntary carbon markets (VCMs) to ensure they drive credible climate action and economic opportunities. These principles aim to establish robust standards for carbon credits, improve market functioning, and ensure fair treatment of participants. The administration's efforts include creating new climate opportunities for farmers, advancing carbon dioxide removal technologies, and supporting international market development. The goal is to enhance the integrity and effectiveness of VCMs in achieving the U.S.'s ambitious climate goals.
