- 9 January: a report published in Advances in Atmospheric Sciences said that ocean heat content in 2025 had reached a new record for nine consecutive years.[2]
- 9 January (reported): an Oxfam report concluded that the richest 1% exhausted their annual carbon budget in ten days.[3] (Carbon budget is the amount of carbon dioxide that can be emitted while keeping the planet within 1.5 °C of global warming.)
- 22 January: Ember's European Electricity Review 2026 reported that in 2025, wind and solar energy provided 30% of EU electricity, surpassing fossil power (29%) for the first time, and generating more power than fossil sources in 14 of 27 EU countries.[4]
Natural events and phenomena
[edit]- 4 February: a study published in Science Advances concluded that wildfire smoke fine particulate matter (PM2.5) was responsible for ~24,100 all-cause deaths per year in the contiguous United States.[5]
Actions, and goal statements
[edit]Science and technology
[edit]- January (reported): a Chinese company launched the first megawatt-level airborne wind turbine—a 60x40x40 m (197x131x131 ft) helium-filled aerostat—providing electricity through a tether cable from 2,000 metres (6,600 ft) above the ground.[6]
- 14 January: at Concordia Station, Antarctica, the Ice Memory Foundation inaugurated a global repository of mountain ice cores, to ensure that future generations will be able to study past climate conditions.[7]
- 15 January: a study published in Nature Climate Change estimated the 2020 ocean-based social cost of carbon (SCC) to be almost double that of prior SCC estimates that didn't consider ocean-related impacts.[8]
Political, economic, legal, and cultural actions
[edit]- 7 January: US President Donald Trump announced that the United States would be withdrawing from the 1992 United Nations Framework Convention on Climate Change (UNFCC), the UN's Intergovernmental Panel on Climate Change (IPCC), and 65 other international organizations—alleging the treaties "no longer serve American interests".[9] The UNFCC was unanimously ratified by the U.S. Senate in 1992 and signed by then President George H. W. Bush.[10]
- 7 January: US President Donald Trump's Office of Management and Budget received a proposed final rule reversing the 2009 Endangerment Finding, which stated that greenhouse gases endanger public health and welfare by driving climate change. The Endangerment Finding had enabled federal government regulation of greenhouse gas emissions.[11]
- 8 January: US President Donald Trump's administration announced that the country would be withdrawing from the Green Climate Fund, which since 2010 has provided funds to help poorer nations deal with the effects of climate change.[12]
- 27 January: the United States completed its second formal withdrawal from the 2015 Paris agreement—one year after US President Donald Trump signed an executive order to begin the withdrawal process.[10] This second withdrawal reversed Trump's predecessor Joe Biden's re-entry into the agreement after Trump's 2017 first withdrawal.[10]
- 28 January: The Hague District Court ruled that the Dutch government had discriminated against the inhabitants of the Caribbean island of Bonaire, by not taking timely and appropriate measures to protect them against the consequences of climate change. The court ordered the Dutch government to set legally binding targets to reduce greenhouse gas emissions in line with the Paris Agreement, as well as making a climate adaptation plan for Bonaire. The case was started in early 2024 by 8 local residents of Bonaire, together with Greenpeace Netherlands.[13][14] See: Climate change litigation#Bonaire case
- 30 January: a US federal judge ruled that the Trump administration's Department of Energy violated the law with its "Climate Working Group" of five handpicked climate change skeptics who reject the scientific consensus on climate change.[15] The group's July 2025 A Critical Review of Impacts of Greenhouse Gas Emissions on the U.S. Climate supported the administration's attack on the 2009 Endangerment Finding that underpins the US federal government's legal authority to combat climate change.[15]

[edit]- 28 January: a study published in Nature forecast that climate change could lead to 123 million additional malaria cases and 532,000 additional deaths in Africa between 2024 and 2050 under current malaria control levels.[16] Extreme weather events are thought to cause 79% of additional cases and 93% of additional deaths.[16]
