One out of ten people on Earth is likely to live in a climate impact hotspot by the end of this century, if greenhouse gas emissions continue unabated. Many more are put at risk in a worst-case scenario of the combined impacts on crop yields, water availability, ecosystems, and health, according to a study now published online by the Proceedings of the National Academy of Sciences (PNAS).
For farmers, a warming climate challenges fundamental decisions they have always made based on the certainty of the weather ¨C such as when to plant various crops, which varieties to choose or what investments in cooling or irrigation infrastructure would make the most economic sense. They will soon have a resource to help them navigate the changes: the Cornell Institute for Climate Change and Agriculture. Allison Morrill Chatrchyan becomes its first director Sept. 1.
Below is a statement from Urban Land Institute (ULI) Chief Executive Officer Patrick L. Phillips regarding President Obama’s Climate Action Plan, which the president outlined during a June 25 speech at Georgetown University in Washington, D.C. ULI (www.uli.org) is a nonprofit education and research institute supported by its members. Its mission is to provide leadership in the responsible use of land and in creating and sustaining thriving communities worldwide. Established in 1936, the Institute has nearly 30,000 members representing all aspects of land use and development disciplines.
Many researchers around the world are seeking ways to “scrub” carbon dioxide (CO2) from the emissions of fossil-fuel power plants as a way of curbing the gas that is considered most responsible for global climate change. But most such systems rely on complex plumbing to divert the steam used to drive the turbines that generate power in these plants, and such systems are not practical as retrofits to existing plants.
More frequent bridge failures are one of the risks the public faces from a changing climate. Swiftly moving storm water can scour the dirt and rocks from around bridge piers, leading to collapse.
Just as wealthy nations like the United States are outsourcing their dangerous carbon dioxide emissions to China, rich coastal provinces in that country are outsourcing emissions to poorer provinces in the interior, according to UC Irvine climate change researcher Steve Davis and colleagues.
Flood risk is projected to increase in humid areas in Asia and Africa and decrease in most regions of Europe except the UK and northern France by the end of this century, according to a new model published today in Nature Climate Change.
Chlorofluorocarbons (CFCs) are to blame for global warming since the 1970s and not carbon dioxide, according to new research from the University of Waterloo published in the International Journal of Modern Physics B this week.
LONDON: Is the solution to our biggest collective challenge, climate change, already out there, waiting to be discovered? This is exactly what the EarthHack, a new international competition launched on May 29 in London, wants to achieve: To unleash the power of creative thinking on how existing technology can be re-purposed towards creating tomorrow’s lower carbon homes.
The accelerating disappearance of Earth's species of both wild and domesticated plants and animals constitutes a fundamental threat to the well-being and even the survival of humankind, warns the founding Chair of a new global organization created to narrow the gulf between leading international biodiversity scientists and national policy-makers.
