A new study found that Amazonian forests are impacted by high maximum temperatures, causing tall trees to shed their leaves and branches. The study, led by the University of Helsinki, used LiDAR to track the effects of fragmentation and climate change on plant phenology.
A recent study suggests that climate change in some regions is unavoidable even if CO2 levels are reduced. The intertropical convergence zone (ITCZ) shifts southwards when CO2 decreases, triggering persistent El Niño conditions and regional climate changes.
A new study published in PNAS found that large mammals died out at the end of the last ice age due to a warming climate and vegetation expansion. Rewilding efforts with animals like bison and horses are unlikely to reverse this trend, as climate change remains the primary driver of ecosystem changes.
A new study reveals that the Little Ice Age was triggered by an unusually warm episode in the late 1300s, with strong northward transfer of warm water and high solar activity contributing to the phenomenon. The researchers found that this warming event led to rapid arctic ice loss and subsequent cooling of North Atlantic waters.
A nationwide study in Brazil found that temperature changes contributed to over 202,000 cases of kidney disease between 2000-2015. The study showed a strong association between increased temperature and hospitalizations for renal diseases.
Research finds that human settlement led to increased fires and soil erosion, altering unique island ecosystems in Macaronesia. The study also shows that colonial-era settlers had a greater impact on vegetation than aboriginal settlers.
A new study finds that greenhouse warming will increase North Tropical Atlantic variability, causing more frequent extreme events like hurricanes and droughts. The research also reveals an amplification of ENSO-induced temperature anomalies due to increased ENSO variability in a warming climate.
A new approach to analyze satellite measurements shows that clouds are likely to enhance global heating, further exacerbating climate change. The research suggests that a doubling of atmospheric carbon dioxide concentrations will lead to an average warming of more than 3°C.
