Smithsonian: Globaler Wandel
Heute ist mehr Kohlendioxid (CO2) in der Atmosphäre als seit 3 Millionen Jahren. Treibhausgase wie Kohlendioxid, Methan und Lachgas fangen Wärme in der Erdatmosphäre...
1.7-billion-year-old fossils reveal a crucial clue to the rise of complex life
Scientists studying ancient Australian rocks uncovered more than 12,000 fossils from some of the oldest known eukaryotes on Earth. These early complex cells lived...
Earth may have lost the Sun’s protective shield millions of years ago
NASA-funded studies suggest Earth’s climate has been influenced by both the Sun’s travels through dense regions of the Milky Way and the violent superflares...
UN: Anstieg über 1,5 Grad so kurz wie möglich halten
Auf ein inzwischen unvermeidliches Übersteigen der 1,5-Grad-Marke in der Klimakrise muss dem UN-Umweltprogramm (Unep) zufolge eine möglichst rasche Rückkehr unter diesen Wert folgen. Risiken...
Forces deep inside Earth helped Antarctica freeze before the Arctic
Scientists may have solved the mystery of why Antarctica froze millions of years before the Arctic. Slow-moving waves deep inside Earth gradually lifted East...
Scientists discover a natural Arctic cloud factory missing from climate models
A newly discovered Arctic process can dramatically boost the number of particles that help form clouds. Near melting sea ice, sunlight reacts with chemicals...
Air pollution linked to distinct brain changes in regions vulnerable to Alzheimer’s disease
USC researchers found that exposure to common air pollutants was associated with different patterns of cortical thickness in two groups of older adults, pointing...
Scientists detect a sharp acceleration in global warming
Global warming appears to have shifted into a faster gear. After removing the effects of El Niño, volcanic eruptions, and solar cycles, researchers found...
Threefold increase in atmospheric–riverine compound heatwaves under climate change
Record-breaking heatwaves disrupt global water, energy and food systems, yet the co-occurrence of atmospheric and riverine events remains largely unexplored. Here we analyse 796...
Deep convection only temporarily intensified by aerosols
A sudden rise in aerosols makes clouds more active for about a day. Then the effect fades as the atmosphere adjusts and warms aloft,...
