Does climate change seriously threaten to wipe out the human species if left unchecked? Examining our evolutionary past suggests it might once have been the perfect catalyst for our extinction. But now?

A device the size of a deck of playing cards that can track temperature, humidity, light and barometric pressure is moving from the shipping world to the realm of research to help develop a better understanding of how the climate is changing.

An international research team including University of Pennsylvania scientists has shown that the rate of sea-level rise along the U.S. Atlantic coast is greater now than at any time in the past 2,000 years and that there is a consistent link between changes in global mean surface temperature and sea level.

On the heels of another halting round of talks on climate change, UN scientists this week will review quick-fix options for beating back the threat of global warming that rely on technology rather than political wrangling.

Native vegetation must be restored to protect Australia's unique ecosystems from the impacts of climate change, according to scientists from the Australian National University.

New research shows people may not be responsible for the rarity of a native tree species - a finding that could change how conservation is approached.

Cornell researchers are calling on their colleagues around the world to focus on how aging global populations will intersect with climate change and calls for environmental sustainability.

Medical and military leaders have come together today to warn that climate change not only spells a global health catastrophe, but also threatens global stability and security.

The authors of a recent Perspectives piece in the journal Nature Climate Science say it is not enough to intuit the success of climate communications. They contend the evaluation of climate communication should be met with the same rigor as climate science itself. Here, someone uses the 220 megapixel HiPerWall display at the University of California, San Diego to discuss 10 time varying Intergovernmental Panel on Climate Change simulation runs.

Mangroves, which have declined by up to half over the last 50 years, are an important bulkhead against climate change, a study released on Sunday has shown for the first time.

A carefully executed operation to validate data from CryoSat has shown what can be accomplished when ESA, NASA and others join forces to further our understanding of how the fragile polar environment is responding to climate change.

Active efforts are required to preserve biodiversity in the seas - that far most people are in agreement. But in our enthusiasm to save uncommon species, we sometimes miss the common species that form the basis of marine ecosystems. 'Change strategy' is the challenge to the authorities from researchers at the University of Gothenburg, Sweden.

According to a series of articles published in Nature, the world has too many PhDs and not enough academic jobs to sustain them. Researchers point out that it is either time to make changes in the system or eliminate it altogether.

The concept of time as a way to measure the duration of events is not only deeply intuitive, it also plays an important role in our mathematical descriptions of physical systems. For instance, we define an object's speed as its displacement per a given time. But some researchers theorize that this Newtonian idea of time as an absolute quantity that flows on its own, along with the idea that time is the fourth dimension of spacetime, are incorrect. They propose to replace these concepts of time with a view that corresponds more accurately to the physical world: time as a measure of the numerical order of change.

More carbon dioxide in the atmosphere causes soil to release the potent greenhouse gases methane and nitrous oxide, new research published in this week's edition of Nature reveals. "This feedback to our changing atmosphere means that nature is not as efficient in slowing global warming as we previously thought," said Dr Kees Jan van Groenigen, Research Fellow at the Botany department at the School of Natural Sciences, Trinity College Dublin, and lead author of the study.

Greenland's ice sheet melted the most it has in over a half century last year, US government scientists said Tuesday in one of a series of "unmistakable" signs of climate change.

David Keith is Gordon McKay Professor of Applied Physics at Harvard's School of Engineering and Applied Sciences, and Professor of Public Policy at Harvard Kennedy School. The award-winning scientist, who was named one of TIME magazine's Heroes of the Environment in 2009, has worked near the interface of climate science, energy technology, and public policy for twenty years. He divides his time between Boston and Calgary, where he serves as president of Carbon Engineering-a start-up company developing industrial-scale technologies for capture of CO2 from ambient air. Here, Keith answers questions about his research and ideas for reducing climate change using innovative and sometimes controversial methods.

Glacial meltwater increases biodiversity in mountainous freshwater ecosystems. As glaciers vanish due to global warming, so will those species dependent upon the icy runoff. This is the conclusion of a study authored by researchers from, among other institutions, the University of Copenhagen.

Modern futurism began at the dawn of the 20th century with a series of essays by H.G. Wells, which he called "Anticipations." Wells proposed that serious thinkers should write soberly, factually and objectively about the great "mechanical and scientific progress" transforming human affairs. But if the goal of futurism is to shed enlightenment over the dark forces of historical change, then we must recall that history is one of the humanities, not a hard science. Tomorrow obeys a futurist the way lightning obeys a weatherman. Still, while it might be impossible to know the future, that hasn't stopped people from forecasting it-and sometimes in ways that are of real, practical use.

"There is enough energy available in winds to meet all of the world's demand. Atmospheric turbines that convert steadier and faster high-altitude winds into energy could generate even more power than ground- and ocean-based units. New research from Carnegie's Ken Caldeira examines the limits of the amount of power that could be harvested from winds, as well as the effects high-altitude wind power could have on the climate as a whole. Their work is published September 9 by Nature Climate Change."
