The Middle East and North Africa Region (MENA) is a climate change hot spot where summers warm much faster than in the rest of the world. 

The last glacial period, which lasted about 100,000 years, reached its peak about 20,000 to 25,000 years ago: Huge ice sheets covered large parts of northern Europe, North America and northern Asia, some of them kilometres thick, and the sea level was about 125 metres below today's level. 

A new study co-authored by a Tulane University geoscientist shows that human efforts to tame the Mississippi River may have had an unintended positive effect: more rapid transport of carbon to the ocean.

Understanding the evolution of the polar sea ice is not enough to study the effects of the climate change on marine ecosystems in Antarctic seafloors.

One of the surest signs of spring is the vibrantly lime-green tinge trees develop as their buds open and tiny new leaves unfurl. 

The world needs more electricity. As populations grow, standards of living increase and more people gain access to modern conveniences, countries will need to expand their energy generation capacity.

After eight months of research, deliberation, discussion and numerous town halls, the Academic Senate Ad Hoc Committee on Divestment and Strategic Reinvestment Investigations has published a preliminary draft report detailing recommendations for the University of Utah to divest its holdings in the fossil fuel industry and reinvest in renewable resources.

Beneath the cold, dark depths of the Arctic ocean sit vast reserves of methane.

Every year 600-900 million tons of carbon flow through rivers to the ocean either as particles or in dissolved form. 

Notwithstanding last month’s cold snap in Texas and Louisiana, climate change is leading to warmer winter weather throughout the southern U.S., creating a golden opportunity for many tropical plants and animals to move north, according to a new study appearing this week in the journal Global Change Biology.
