Breathing in air pollution like ozone and PM2.5 harms nearly every major system in the human body
Like living beyond your financial means, using more water than nature can replenish can have catastrophic results.
Flagship report calls for fundamental reset of global water agenda as irreversible damage pushes many basins beyond recovery
A new international analysis published in Advances in Atmospheric Sciences on 9 January finds that the Earth's ocean stored more heat in 2025 than in any year since modern measurements began. The finding is the result of a major international collaboration led by the Institute of Atmospheric Physics at the Chinese Academy of Sciences, involving more than 50 scientists from 31 research institutions worldwide. The 2025 heat increase was 23 Zetta Joules (23,000,000,000,000,000,000,000 Joules of energy), which is equivalent to ~37 years of global primary energy consumption at the 2023 level (~620 Exa Joules per year). The assessment combines data from major international data centers and independent research groups, including three observational products (Institute of Atmospheric Physics at the Chinese Academy of Sciences; Copernicus Marine; and NOAA/NCEI) and an ocean reanalysis (CIGAR-RT) from three continents: Asia, Europe, and America. These groups confirm that the 2025 ocean heat content (OHC) reached the h

Exclusive: UCL scientists find large swathes of southern Europe are drying up, with ‘far-reaching’ implications
Logging and mining are destroying swathes of the Congo rainforest, with the result that African forests went from being  a carbon sink to a carbon source in 2010 to 2017
The growth rate of greenhouse gas (GHG) climate forcing increased rapidly in the last 15 years to about 0.5 W/m2 per decade, as shown by the “colorful chart” for GHG climate forcing that we have been publishing for 25 years (Fig. 1).[1] The chart is not in IPCC reports, perhaps because it reveals inconvenient facts. Although growth of GHG climate forcing declined rapidly after the 1987 Montreal Protocol, other opportunities to decrease climate forcing were missed. If policymakers do not appreciate the significance of present data on changing climate forcings, we scientists must share the blame.
Gates recently called for a ‘strategic pivot’ in climate strategy. That appears to have hit a nerve.
We propose a new paradigm, as toxicology currently lacks the proper perspective. From the 1950s to the 1970s, at least one-third of all toxicological testing in the United States, including for chemicals and drugs, was misleading scientists, and this worldwide issue persists today. Moreover, petroleum-based waste and heavy metals have been discovered in pesticide and plasticizer formulations. These contaminations have now reached all forms of life. Widespread exposure to chemical mixtures promotes health and environmental risks. We discovered that pesticides have never undergone long-term testing on mammals in their full commercial formulations by regulatory authorities or the pesticide industry; instead, only their declared active ingredients have been assessed, contrary to environmental law recommendations. The ingredients of these formulations are not fully disclosed, yet the formulations are in general at least 1000 times more toxic at low environmentally relevant doses than the active ingredients alone u

“I suppose it is tempting, if the only tool you have is a hammer, to treat everything as if it were a nail.” Thus wrote the famous psychologist Abraham Maslow in 1966.
22 of the planet’s 34 vital signs are at record levels, with many of them continuing to trend sharply in the wrong direction. This is the message of the sixth issue of the annual “State of the climate” report. The report was prepared by an international coalition with contribution from the Potsdam Institute for Climate Impact Research (PIK) and led by Oregon State University scientists. Published today in BioScience, it cites global data from the Intergovernmental Panel on Climate Change (IPCC) in proposing “high-impact” strategies.
CO2 in air hit new high last year, with scientists concerned natural land and ocean carbon sinks are weakening
Unless global heating is reduced to 1.2C ‘as fast as possible’, warm water coral reefs will not remain ‘at any meaningful scale’, a report by 160 scientists from 23 countries warns
German scientists warn global warming is accelerating faster than expected, raising the risk of a 3 °C rise by 2050 and forcing Europe to confront unthinkable adaptation plans.

Climate.gov, which went dark this summer, to be revived by volunteers as climate.us with expanded missionEarlier this summer, access to climate.gov – one of the most widely used portals of climate information on the internet – was thwarted by the Trump administration, and its production team was fired in the process.
Some experts tee up public comment on EPA report calling fossil fuel concerns overblown, as others fast-track review
The report, which is being used to justify the rollback of a huge number of climate regulations, is full of misinformation—with many claims based on long-debunked research.

blue whale vocalizations dropped by almost 40 percent, according to the study, with populations of krill and anchovy collapsing. "When you really break it down, it’s like trying to sing while you're starving," Ryan explained. "They were spending all their time just trying to find food."

Rising temperatures are causing water to evaporate and driving humans to extract more groundwater, which is moving freshwater from the land to the seas and creating a "continental drying" trend..
