🌡️ Oceans absorbed a record 23 zettajoules of heat in the past year, significantly increasing ocean temperatures, sea levels, and acidity.

🌊 Sea levels have risen by 3.8mm per year since 1999, with an accelerated rate of 4.2mm per year from 2012 to 2025.

🐠 Marine heatwaves have impacted regions like the Mediterranean and Black Seas, leading to coral bleaching affecting 84% of the world's coral reefs and impacting penguin colonies.

🧊 A new study in Nature Geoscience reveals Antarctica's ice loss this century is inevitable, even if global warming is limited to 1.5°C.

💻 Researchers used machine learning to analyze millions of scenarios, finding that Antarctica will contribute more to sea-level rise than currently projected.

🌊 The study emphasizes that reducing greenhouse gas emissions is crucial, as extra snowfall won't offset ice loss due to a warming ocean. Without emission cuts, Antarctica alone could contribute up to 10 inches (25 cm) of sea-level rise by 2100.

❄️ Winter 2025-2026 saw among the least snow in Swiss history; subsequent hot, dry conditions from May to September 2026 caused excessive melt, with heatwaves pushing the freezing point above 4,000 meters for a record 76 days.

💧 Glaciers released ~2,200 billion litres of water from July to September, temporarily easing summer water shortages. This is a dwindling resource due to shrinking glacier size.

🧊 August 2024 saw an unprecedented open water area (polynya) of 89,121 sq km in Breid Bay, East Antarctica, larger than Portugal, during a time it's usually frozen solid.

💨 This massive hole was caused by extreme weather: six intense atmospheric rivers ("rivers in the sky") and marine heatwaves brought warm, moist air and ocean water, suppressing sea ice growth and bringing warmer subsurface water to the surface.

📉 Antarctica recorded its third-lowest winter sea ice extent this year, with the four lowest records occurring in the past four years, highlighting a concerning trend driven by human-caused climate change.

A 27-year study across Alaska found soils are warming at considerable depths, with permafrost regions warming fastest at 0.64°C per decade, while 100% of monitoring stations showed warming 4 feet underground, raising concerns about permafrost thaw, carbon release and infrastructure.

🌡️ Alaska's air temperatures are rising twice as fast as in the contiguous U.S., with recent research revealing significant soil warming across the state.

📉 A 27-year study (1997-2023) analyzed data from 43 weather stations, finding that average annual soil temperatures increased significantly across all permafrost regions. The fastest warming rates were observed at higher latitudes.

🌲 Soil warming was observed across the entire soil profile, with no significant differences in warming rates based on depth. The presence and depth of snow significantly influenced the relationship between air and soil temperatures, buffering soils from extreme air temperatures in winter.

📈 Climate change risks doubling the likelihood of wheat price spikes, and increasing maize and soybean prices by factors of 2.70 and 2.45, respectively.

🌾 This translates to an increased risk of losing 0.24, 0.71, and 1.20 million calories per capita annually for wheat, maize, and soybean consumption.

🌍 Food system vulnerabilities like concentrated production and import dependencies amplify these risks, with climate change further worsening consumption risks by up to 6 Mcal per capita per year in exposed regions.

🌲 Swiss Forests Facing Increased Drought Stress: A 40-year study reveals a general decline in the stability and productivity of growing forest stands, evidenced by decreasing growth and accelerating stem density losses.

💧 Vanishing Altitude Effect: The influence of altitude on forest canopy moisture resilience is disappearing, indicating a convergence of drought adaptation levels across different elevations.

📉 Declining Stands Exceeding Thresholds: Stands experiencing decline are consistently exposed to higher drought stress, with fundamental resilience limits being surpassed regardless of altitude.

🌳 Shift in Resilience: The key factor signaling decline in these stands has shifted from initial resistance to recovery over time, suggesting that adaptations are not enough to prevent continued decline.

A study combining satellite, ground and atmospheric model data found global desert dust declined by about 10% between 2003 and 2023, modestly reducing its cooling effect on the climate, although the contribution to recent human-caused warming remains very small.

💧 The Dead Sea is warming due to a feedback loop where water loss increases salt concentration, weakening evaporative cooling and leading to further warming and evaporation.

💧 Human diversion of water has contributed significantly to the Dead Sea's warming, with declining water levels accounting for about 1.5°C of deep-water warming between 1979 and 2019, compared to 1.3°C from rising air temperatures.

💧 Projections suggest the Dead Sea could decline by 85 meters and warm by 5–8°C by 2100, depending on greenhouse gas emissions, if inflows stop.

💧 A study on a simulated ancient, isolated basin showed that shrinkage and increasing salt concentration can lead to significant warming (around 20°C over 8,000 years) even without extremely hot regional climates.

A study of 154 archival documents found the U.S. cattle industry’s leading trade association knew about livestock’s contribution to global warming by 1989 but focused on downplaying methane emissions, challenging climate science and opposing efforts to reduce beef consumption.

* 🐄 In the mid-1980s, scientific studies revealed that cow emissions significantly contribute to global warming. The National Cattlemen’s Association (NCA) responded not with emission reduction strategies, but with strategic communication.

* 📝 Between 1986 and 1996, the NCA focused on gathering information, hiring experts to reframe scientific data, and influencing public and political discourse. They treated global warming primarily as a public relations issue impacting consumer demand.

* 🔬 Despite scientific recommendations for reducing methane emissions through production changes, the NCA's research and internal documents show no evidence of efforts to explore or promote such changes.

For the first time ever, scientists comprehensively mapped all glaciers in the lower 48 US states. They found 1/4 disappeared and total area/volume shrank by 35% (195.29 km², 5.53 gigatons of ice) since the mid-20th century—reducing vital water runoff alpine ecosystems rely on to buffer droughts.

Telling people online they eat meat because they don't care about the planet mostly makes them defensive, not ready to change. Saying they just don't know how to cook plant-based meals got less pushback. And a private DM from a stranger made people even angrier than the same comment posted publicly.
