 1 January: a study published in Science Advances concluded that faster flow of the Antarctic Circumpolar Current (ACC) at higher latitudes causes upwelling of isotopically light deep waters around Antarctica, likely increasing atmospheric carbon dioxide levels and thereby potentially constituting a critical positive feedback for future warming.
 6 January: a study published in Nature Climate Change stated that a fungal pathogen (Entomophaga maimaiga) that had successfully controlled the  defoliation of the spongy moth in North American forests was becoming less effective due to climate change producing hotter, drier conditions. The study predicts this will lead to significantly decreased forest biodiversity and productivity by spongy moths, evidenced by recent increases in defoliation.
 7 January: NOAA's Arctic Report Card 2024 reported that, including the impact of increased wildfires, the Arctic tundra region had shifted from storing carbon in the soil to becoming a carbon dioxide source, and that the Arctic remained a consistent source of methane—both adding to planet-warming greenhouse gases in the air.Moon, Twila A.;Druckenmiller, Matthew L.;Thoman, Richard L., editors. 
 8 January: a study published in Nature concluded that one-quarter of 23,496 decapod crustaceans, fishes and odonates studied, some of which provide climate change mitigation, are threatened with extinction. One-fifth of threatened freshwater species are affected by climate change and severe weather events.
 9 January: a study published in Nature Reviews Earth &amp; Environment estimated that since the mid-twentieth century, global-averaged 3-month and 12-month "hydroclimate whiplash" events have increased by 31–66% and 8–31%, respectively. Such increases amplify hazards associated with rapid swings between wet and dry states, including flash floods, wildfires, landslides and disease outbreaks. (Hydroclimate volatility refers to "sudden, large and/or frequent transitions between very dry and very wet conditions".)
 15 January: a study published in Weather reported that the terrestrial biosphere's rate of natural carbon dioxide sequestration has fallen since its 2008 peak at a rate of 0.25% per year, a decline that will accelerate climate change.
 21 January: a study published in the Proceedings of the National Academy of Sciences reported an "abrupt, coherent, climate-driven transformation" from "blue" (more transparent) to "brown" (less transparent) states of lakes in Greenland after a season of both record heat and rainfall drove a state change in these systems. This change was said to alter "numerous physical, chemical, and biological lake features", and the state changes were said to be unprecedented.
 February (reported): though polar bears and grizzly bears traditionally occupy distinct habitats (marine and land), arctic warming has forced polar bears inland into grizzly bear habitats, where the two species mate to produce hybrid "grolar bears" that have characteristics poorly adapted to either marine or land habitats.
 4 February: a study published in Environmental Research Letters concluded that, in addition to the 2023 marine heat wave, an extensive river plume caused a ~ thick strongly stratified barrier layer that contributed to Hurricane Idalia's rapid intensification (Category 1 to Category 4 in less than 24 hours).
 21 February: a study published in npj Natural Hazards unified studies of climatic trends and of wildland-urban interface (WUI) expansion, and concluded that climatic factors increased the frequency of high-risk fire weather by a factor of 2.5, and that the combination of climatic factors with WUI expansion led to a 4.1-fold increase in the frequency of conditions conducive to extreme-impact wildfires from 1990 to 2022 across California.
 26 February: a study published in Nature concluded that the Atlantic meridional overturning circulation (AMOC) is resilient to extreme greenhouse gas and North Atlantic freshwater forcings across 34 climate models, suggesting that an AMOC collapse is unlikely in the 21st century.
 26 February: a study published in Science Advances concluded that short-, mid-, and long-term ambient outdoor heat can significantly accelerate epigenetic aging in older adults.
 5 March: a study published in Geophysical Research Letters concluded that redistribution of mass caused by melting of ice sheets and glaciers will shift the Earth's rotational poles from  by 2100, depending on the degree of future global warming. Changing Earth's rotational axis affects spacecraft navigation and orientation of deep space telescopes.
 10 March: a study published in Nature Sustainability projected that climate change's cooling of the atmosphere occupied by space debris in low Earth orbit will reduce the atmosphere's drag on the debris, extending the debris' lifetime and potentially causing a 50–66% reduction in satellite carrying capacity at altitudes .
 19 March: an article published in Nature said that two major natural events occurred at the end of the last ice age: around 10,300 and 8,300 years ago, sea levels surged rapidly due to meltwater releases from the North American and Antarctic ice sheets, with peak rates of sea-level rise reaching nearly 9 mm/year — comparable to projections for the year 2100 under high-emissions scenarios.
 25 March: an article published in Nature said that volcanic eruptions over the past 603 years have significantly impacted the strength and tilt of the Atlantic jet stream, which in turn influenced extreme weather events in Europe. These jet stream shifts contributed to increased droughts when moving north and heightened flood risks when shifting south.
 10 April: NOAA published a statement that after a few months of La Niña conditions, the tropical Pacific was ENSO-neutral and was likely to remain so through autumn, stating the most recent La Niña phase was very brief.
 21 April: NOAA confirmed the Earth was experiencing its fourth global coral bleaching event, which it called the biggest to date: from 1 January 2023 to 20 April 2025, bleaching-level heat stress had impacted 83.7% of the world’s coral reef area, and mass coral bleaching had been documented in at least 83 countries and territories.
 30 April: a study published in Nature Communications described how melting of sea ice caused by global warming allows increased areas of open water—which passes a narrower spectrum of light than the smooth continuum of frequencies passed by sea ice—to "cause major changes in both the pigment and species composition of primary producers in polar ecosystems". These changes affect photosynthesis in ocean phytoplankton.
 6 May: a study published in Nature Communications concluded that glacial melt is accelerated even when ocean temperatures are constant, a phenomenon caused when cold fresh meltwater rushing from beneath glaciers creates upward turbulence, drawing in warm ocean water from below.
 8 May: NOAA's April 2025 U.S. Climate Report documented a slow-moving storm system that brought over 150 tornadoes to the South and Midwest, resulting in at least 24 fatalities and widespread flooding. This event underscores the increasing frequency of severe convective storms in a warming climate.
 20 May: a study published in Communications Earth &amp; Environment concluded that merely maintaining a global average temperature of +1.5°C is inadequate to avoid extensive loss and damage to coastal populations in coming centuries, and hypothesized that "+1°C above pre-industrial, possibly even lower" is required to avoid such loss and damage.
 31 May: a study published in Communications Earth &amp; Environment suggested that as glacial melt exposes soil, glacial meltwater's net sequestration of carbon dioxide gives way to water from exposed soil that enhances methane and carbon dioxide production, switching from a negative to positive warming feedback.
 4 June: a study published in Nature concluded that atmospheric evaporative demand (AED)—"atmospheric thirst" causing moisture to be removed from the Earth's surface—has increased drought severity by an average of 40% globally.
 9 June: a study published in Global Change Biology suggested that by 2020, global ocean acidity conditions had already crossed into the uncertainty range of the Planetary Boundary Framework. 
 16 June: a study published in the Proceedings of the National Academy of Sciences reported a tripling in the past half-century of the number of planetary wave events caused by quasi-resonant amplification (QRA). Such wave events underlie extreme weather events such as heatwaves, flooding, wildfires, and heat dome events.
 7 July: findings in a study published in  Proceedings of the National Academy of Sciences suggested that current Earth system models overestimate the ability of northern temperate forests to absorb carbon, because the models do not consider the impacts of shrinking snowpack and increased soil freeze/thaw cycles.
 14 July: a study published in Communications Earth &amp; Environment said that accelerated East Asian reduction in aerosol emissions unmasks greenhouse gas-driven warming, enough to be a main driver of the accelerated global warming since 2010.
