"As UN negotiators roll up their sleeves for the last push towards a universal climate deal, many fear their end-goal of halting global warming at two degrees Celsius is moving out of reach."

"Research released today shows that within the next 10 years large parts of Asia can expect increased risk of more severe droughts, which will impact regional and possibly even global food security."

"A new study has found that climate-prediction models are good at predicting long-term climate patterns on a global scale but lose their edge when applied to time frames shorter than three decades and on sub-continental scales."

Plunge in CO2 put the freeze on AntarcticaAtmospheric carbon dioxide levels plunged by 40% before and during the formation of the Antarctic ice sheet 34 million years ago, according to a new study. The finding helps solve a long-standing scientific puzzle and confirms the power of CO2 to dramatically alter global climate.

Parasitic worms that infect fish, and have a devastating effect on fish reproduction, grow four times faster at higher temperatures - providing some of the first evidence that global warming affects the interactions between parasites and their hosts.

Emissions of carbon dioxide (CO2) from fossil fuels and the cement industry scaled a record high in 2010, rocketing by 5.9 percent over 2009 in a surge led by developing countries, scientists reported on Sunday.

Scientists are a step closer to predicting when and where earthquakes will occur after taking a fresh look at the formation of the Andes, which began 45 million years ago.

Unprecedented levels of greenhouse gases in the Earth's atmosphere are disrupting normal patterns of glaciation, according to a study co-authored by a University of Florida researcher and published online Jan. 8 in Nature Geoscience.

How important is Twitter in the political revolutions sweeping the Middle East? That was the topic of discussion on stage at the CTIA mobile and wireless convention today in Orlando, Florida and two very different, very strong opinions were voiced. "I don't think anyone in their right mind would say that sending a tweet is the equivalent of activism," said Twitter co-founder Biz Stone, "but it's another tool people can use." Kenneth Roth, executive director of of Human Rights Watch, one of the world's most respected human rights organization, framed things very differently though. He said on stage (above) that mobile technology in general would make it impossible today for something like Nazi Germany to unfold again the way it did historically.

The world in which we live would hardly be recognised by someone who lived and died half a century ago and who may have caught a glimpse of the television generation. The children born in the 90′s have only known a world where the Internet was a natural part of  their day to day lives. We now live in a society that verges on a digital tipping point that wraps and integrates our lives with the Web and it is no longer considered a luxury but a necessity in our modern lifestyle. So what is driving us to this digital dawn that is transporting us from the industrial past of the last 200 years and the TV industrial complex that emerged 50 years ago and embracing us in an information age that challenges our paradigms?

During the last quarter-century, average wind speeds have increased over the world's oceans, as have wave heights, generating rougher seas, researchers reported in a study published online Thursday.

The recent cool, wet conditions in Maine may delay the state's blueberry crop for about a week, according to David Yarborough, University of Maine Cooperative Extension's blueberry specialist and UMaine professor of horticulture.

John Harrington Jr., professor of geography, is a synoptic climatologist who examines the factors behind distinctive weather events. He credits the increased tornado production this year to jet stream patterns in the upper atmosphere. The patterns have created synoptic events such as the April tornado outbreak in Alabama and recent tornado in Joplin, Mo. While these events are not unprecedented, they are significant, he said.

global warming may affect the capacity of trees to store carbon by altering forest nitrogen cycling, concludes a study led by Jerry Melillo, Distinguished Scientist at the Marine Biological Laboratory (MBL) Ecosystems Center, and published this week in Proceedings of the National Academy of Sciences.

A team of scientists from the University of Sheffield and Bangor University have used a computer climate model to study how freshwater entering the oceans at the end of the penultimate Ice Age 140,000 years ago affected the parts of the ocean currents that control climate.

By 2050, the coolest summers in the tropics and parts of the northern hemisphere will still be hotter than the most scorching summers since the mid-20th century if global warming continues apace, according to a new study.

It's ubiquitous. It's universal. And it's understood-not! Water's choices in a given situation often defy scientific predictions. When expected to bond with other water molecules, it shuns them. When expected to ignore a surface, it becomes deeply attached. However, research at Pacific Northwest National Laboratory has revealed why one of the simplest and most important molecules on the planet makes some of the decisions it does.

Scientists have observed a "super-aggregation" of more than 300 humpback whales gorging on the largest swarm of Antarctic krill seen in more than 20 years in bays along the Western Antarctic Peninsula.

According to a new study, it could become much warmer towards the end of the century than originally anticipated. The study has found that the average temperatures calculated are much higher than the IPCC's worst-case scenario to date.

Gray whales survived many cycles of global cooling and warming over the past few million years, likely by exploiting a more varied diet than they do today, according to a new study by University of California, Berkeley, and Smithsonian Institution paleontologists.
