Conditions that, by today’s standards, are considered to be mega-droughts — or conversely, abnormally wet “mega-pluvial” events — may become the average in the future, according to new research led by the University of California Santa Barbara (UCSB) and co-authored by scientists at the National Center for Atmospheric Research (NCAR).

The western US is facing a greatly heightened risk of extreme rain-after-fire events, which can cause mudslides, flash floods, and significant destruction.

A major new international study shows that the impact of climate change is apparent in nearly all aspects of the climate system with the potential for major impacts on society and vulnerable ecosystems.

The Southern Ocean is indeed a significant carbon sink — absorbing a large amount of the excess carbon dioxide emitted into the atmosphere by human activities — according to a new study led by NCAR.

Scientists have reconstructed Earth's climate in the 24,000 years since the last ice age, highlighting key drivers of climate change and the influence of human activity.
