A new method is being applied to determine whether specific climate impacts can be traced to human-caused emissions. The past century has seen a 0.8°C (1.4°F) increase in average global temperature, and the overwhelming source of this increase has been emissions of greenhouse gases and other pollutants from human activities, they say.

Winter precipitation can bring an increased risk for slips and falls on the ice and snow. An expert recommends some simple steps to minimize fall risk.

A team of researchers has published their analysis of data, specimens, photographs and video footage collected in 2009, when they sent a remotely operated vehicle (ROV) to a depth of 800 meters (2,625 ft) at Osprey Reef off the far-northern coast of eastern Australia.

Early human agriculture cancelled natural cooling of Earth's climate, new ice core data and other evidence confirm. Earth naturally cycles between cool glacial periods and warmer interglacial periods because of variations in its orbit around the sun. We currently are in an interglacial period, called the Holocene epoch, which began nearly 12,000 years ago.

Scientists are looking for life in an area of Antarctica that is thought to be the place on Earth that most closely resembles the permafrost found in the northern polar region of Mars, at the Phoenix landing site. The scientists failed to find any active microbes, suggesting it will be unlikely and difficult to detect similar activity on Mars.

Around 720-640 million years ago, much of the Earth's surface was covered in ice during a glaciation that lasted millions of years. Explosive underwater volcanoes were a major feature of this 'Snowball Earth,' according to new research.

Climate change increases the danger of falling rocks in the Alps and other mountain regions, adding to existing risks for mountain climbers.

A new study measured a melt rate that is 25 times higher than expected on one part of the Ross Ice Shelf. The study suggests that high, localized melt rates such as this one on Antarctica's largest and most stable ice shelf are normal and keep Antarctica's ice sheets in balance.

Soil frost is a nearly universal process in the Arctic. In a recent dissertation, it is shown that the frequency and extent of soil frost is important for the release of the greenhouse gas carbon dioxide from arctic soil.

New research on West Antarctic seabed life reveals that the remote region of the South Orkney Islands is a carbon sink hotspot. The findings suggest that this recently designated (and world's first) entirely high seas marine protected area may be a powerful natural ally in combating rising carbon dioxide as sea ice melts.

Humanity has become a geological force that is able to suppress the beginning of the next ice age, a study shows. Cracking the code of glacial inception, scientists have found the relation of insolation and carbon dioxide concentration in the atmosphere to be the key criterion to explain the last eight glacial cycles in Earth history.
