Efforts to dim Sun and cool Earth must be blocked, say scientists

Scientists are calling on political institutions to place limits on solar geoengineering research so that it cannot be deployed unilaterally by countries, companies or individuals. Long-term planetary-level geoengineering interventions of this kind are unprecedented and extremely dangerous, say the academics behind the letter, and should not therefore be experimented with outdoors, receive patents, public funds… Continue reading Efforts to dim Sun and cool Earth must be blocked, say scientists

Improving climate model projections of carbon and heat uptake in the Antarctic Ocean

Cumulative uptake of anthropogenic carbon simulated by climate models during the 1850–2100 period using the high-emission scenario (RCP8.5). Red areas depict high uptake of carbon by the Ocean. On the left, the weakly-stratified models show a stronger carbon uptake between 30°S and 55°S than the strongly-stratified models on the right. Credit: Bourgeois et al. (2022)… Continue reading Improving climate model projections of carbon and heat uptake in the Antarctic Ocean

Five ways climate change increases the threat of tsunamis, from collapsing ice shelves to sea level rise

Credit: Shutterstock The enormous eruption of the underwater volcano in Tonga, Hunga Tonga-Hunga Ha’apai, triggered a tsunami that reached countries all around the Pacific rim, even causing a disastrous oil spill along 21 beaches in Peru. In Tonga, waves about 2 meters high were recorded before the sea level gauge failed, and waves of up… Continue reading Five ways climate change increases the threat of tsunamis, from collapsing ice shelves to sea level rise

Satirical obituary for the Great Barrier Reef undermines climate action
