Climate regulation changed with the proliferation of marine animals and terrestrial plants
Climate regulation carbon-silicon cycle temperature
2021/8/3
Earth's climate was relatively stable for a long period of time. For three billion years, temperatures were mostly warm and carbon dioxide levels high - until a shift occurred about 400 million years ...
How climate change and fires are shaping the forests of the future
climate change fires forests
2021/8/3
As temperatures rise, the risk of devastating forest fires is increasing. Researchers are using artificial intelligence to estimate the long-term impact that an increased number of forest fires will h...
Disparities of climate change mapped
climate change global climate system greenhouse emissions
2021/8/3
New research illustrates the disparity between the narrow origins and far-reaching impacts of greenhouse emissions responsible for disrupting the global climate system.
Plant material that lies to rot in soil isn't just valuable as compost. In fact, agricultural crop residue plays a crucial role in sequestering carbon, which is vital for reducing global CO2 emissions...
Huge volcanic eruption disrupted climate but not human evolution
volcanic eruption climate disruption human evolution
2021/8/3
A massive volcanic eruption in Indonesia about 74,000 years ago likely caused severe climate disruption in many areas of the globe, but early human populations were sheltered from the worst effects, a...
Climate changed the size of our bodies and, to some extent, our brains
evolution climate changed brain body environmental
2021/8/4
The average body size of humans has fluctuated significantly over the last million years and is strongly linked to temperature. Colder, harsher climates drove the evolution of larger body sizes, while...
Ancient ostrich eggshell reveals new evidence of extreme climate change thousands of years ago
