A whole-genome analysis suggests that polar bear numbers waxed and waned with climate change, and that the animals may have interbred with brown bears since becoming a distinct species millions of years ago.
Researchers have found a way to use GPS to measure short-term changes in the rate of ice loss on Greenland – and reveal a surprising link between the ice and the atmosphere above it.
According to NOAA scientists, the globally averaged temperature for June 2012 marked the fourth warmest June since record keeping began in 1880.
Scientists from the University of Toronto and the University of California Santa Cruz are shedding light on one potential cause of the cooling trend of the past 45 million years that has everything to do with the chemistry of the world's oceans.
Global warming also affects lakes. Based on the example of Lake Zurich, researchers from the University of Zurich demonstrate that there is insufficient water turnover in the lake during the winter and harmful Burgundy blood algae are increasingly thriving.
For the first time scientists at ETH Zurich have examined globally the connection between soil moisture and extreme heat with measured data. Their study shows that precipitation deficits increase the probability of hot days in many regions of the world. The results will help to better assess heat risks.
Citing recent wildfires in Colorado, Texas, Russia, Greece, and Chile and a report from climate scientists at the University of California, Berkeley and Texas Tech University, a top official at Lloyd’s said insurers face new challenges from wildfires in many parts of the world.
Worldwide, 2011 was the coolest year on record since 2008, yet temperatures remained above the 30 year average, according to the 2011 State of the Climate report released online today (July 10, 2012) by NOAA.
“Cows are happy in parts of Northern California and not in Florida” is a good way to sum up the findings of new research from the University of Washington, said Yoram Bauman, best known as the “stand-up economist.”
Because the gradual increase in temperatures worldwide is still relatively new, researchers have had difficulty in finding examples of genetic changes in organisms that are adapting to the warmer temperatures.
The continent of Antarctica is at risk from human activities and other forces, and environmental management is needed to protect the planet's last great wilderness area.
Switzerland's highest peaks in the geologically young central Alps have been this high for quite some time, as a new study shows.
No matter how you drill it, using natural gas as an energy source is a smart move in the battle against global climate change and a good transition step on the road toward low-carbon energy from wind, solar and nuclear power.
Researchers are working to identify exactly how a changing climate will impact specific elements of weather, such as clouds, rainfall, and lightning.
An international team that includes scientists from Johannes Gutenberg University Mainz (JGU) has published a reconstruction of the climate in northern Europe over the last 2,000 years based on the information provided by tree-rings.
Marine scientists at the University of North Carolina at Chapel Hill have linked the decline in growth of Caribbean forereef corals -- due to recent warming -- to long-term trends in seawater temperature experienced by these corals located on the ocean-side of the reef.
The combination of melting sea ice and global atmospheric warming are contributing to the high rate of warming in the Arctic, where temperatures are increasing up to four times faster than the global average, a new University of Melbourne study has shown.
A University of Saskatchewan-led international research team has discovered that aerosols from relatively small volcanic eruptions can be boosted into the high atmosphere by weather systems such as monsoons, where they can affect global temperatures.
The recent heat wave baking much of the country has prompted many people to ask: Is this due to climate change?
Climate change drove coral reefs to a total ecosystem collapse lasting thousands of years, according to a paper published this week in Science.
