It was not only a century of poverty, war and revolutions in what is now Germany, but also of variable climate. Starting at the tail end of the

This is not just a future prediction; it is a trend that has already been observed in the past decades. The dry, semi-arid regions are expanding into higher latitudes, and temperate, rainy regions are migrating

The global conversation on trees, forests and climate needs to be turned on its head, say scientists, because the direct effects of trees on climate through rainfall and cooling may be more important than their well-studied capacity of storing carbon.

Over the last 800,000 years, pre-industrial atmospheric CO2 content remained below 280 ppm, but it has now risen to the 2016 global average of 403.3 ppm.

This eruption formed the vast Yellowstone caldera observed today, the second largest on Earth. Two layers of volcanic ash

The research published in the journal Science Advances predicts that as the oceans warm fish — which appear

The current period of climate change may be unparalleled over the last 100 million years, say researchers.
