34 million years ago the warm 'greenhouse climate' of the dinosaur age ended and the colder 'icehouse climate' of today commenced. Antarctica glaciated first and geological data imply that the Atlantic meridional overturning circulation, the global ocean conveyor belt of heat and nutrients that today helps keep Europe warm, also started at this time. Why exactly, has remained a mystery.

A researcher at the University of Kansas has developed an advanced technique for forecasting dusty conditions months before they occur, promising transportation managers, climatologists and people suffering health issues much more time to prepare for dusty conditions.

Do climate shifts influence tornados over North America? New research published by IBS scientists found that Pacific and Atlantic ocean temperatures in April can influence large-scale weather patterns as well as the frequency of tornados over the Great Plains region.

Injecting carbon dioxide (CO2) deep below the seabed could be an important strategy for mitigating climate change, according to some experts. However, scientists need a reliable way to monitor such sites for leakage of the greenhouse gas. Now, researchers reporting in ACS' journal Environmental Science & Technology have studied natural sources of CO2 release off the coast of Italy, using what they learned to develop models that could be applied to future storage sites.

When will we see significant changes in the ocean due to climate change? A new study finds that some changes are noticeable already, while others will take up to a century.

Since the first Homo sapiens emerged in Africa roughly 300,000 years ago, grasslands have sustained humanity and thousands of other species. But today, those grasslands are shifting beneath our feet. Global change -- which includes climate change, pollution and other widespread environmental alterations -- is transforming the plant species growing in them, and not always in the ways scientists expected, a new study published Monday revealed.

Tropical Storm Krosa continued to erode after it moved into the Sea of Japan and satellite data showed it as a ragged and shapeless storm on August 16, 2019.
