Ubsunur Hollow Biosphere Reserve, on the border between Mongolia and Tyva, is one of the last remnants of the mammoth steppe, Earth’s most extensive biome during the Last Glacial Maximum. Last summer, scientists met to discuss changes in ocean circulation between this glacial maximum period and the present time and how these changes are related to changes in the climate and carbon cycling.

December 3, 2017 — Scientists still don’t fully understand the climatic transition that took place on Earth between the Last Glacial Maximum and recent times. Even though carbon cycling and the associated rise in atmospheric carbon dioxide (CO2) during this

November 22, 2017 — When Earth’s atmosphere warms, the vast sheets of ice over Antarctica and Greenland melt. This melting, in addition to the thermal expansion of water, leads to rising sea levels. Although it’s clear that seas are rising at an increasing rate,

November 13, 2017 — From the Everglades in the US to the Great Barrier Reef in Australia, climate change is destroying the many of the greatest wonders of the natural world.

Atmospheric rivers—relatively long, narrow regions in the atmosphere—transport most of the water vapor outside of the tropics. When a large atmospheric river makes landfall, extreme precipitation—sometimes double the amount of rain that fell in the preceding 5 months—and flooding can result. The frequency and intensity of atmospheric rivers and droughts are just two realms explored in a new report that focuses on the effects of climate change across the United States.

These changes will affect sea levels, drought frequency, severe precipitation, and more
November 3, 2017 — Today scientists released a new report that details how climate change is affecting weather and climate across the United States and how future changes in climate could play out across the country.

MANILA, Philippines (Jul. 14, 2017) — A business-as-usual approach to climate change will be “disastrous” for Asia, undoing much of the phenomenal economic growth that has helped it make vast inroads against poverty, the Asian Development Bank said in a report released Friday, July 14.

May 11, 2017 — It’s now “inevitable” that the contiguous United States will lose all of its glaciers within a matter of decades, according to scientists who have revealed the precipitous shrinkage of dozens of glaciers in Montana.
