New research has shown surface ice melt will be the dominant process controlling ice-loss from Greenland. As outlet glaciers retreat inland the other process, iceberg production, remains important but will not grow as rapidly.
Christopher Field, the founding director of Carnegie’s Department of Global Ecology has been awarded one of Germany’s most prestigious prizes, the Max Planck Research Prize with Markus Reichstein “because they have significantly increased our knowledge of how life on Earth responds to climate change and what reactions can be anticipated between the biosphere and the atmosphere… their work also helps us to estimate the consequences of climate change for the people of the planet.”
A United Nations climate conference in Germany last month reaffirmed a global agreement to keep the Earth's temperature from rising more than 2 degrees Celsius (3.6 degrees Fahrenheit) above preindustrial levels.
For the past 40 years — as far back as satellite records show — the frequency and intensity of tropical cyclones has remained relatively stable: About 90 of these storms spin through the world each year, and over the decades, cyclones’ average intensity and maximum wind speed have also remained consistent.
Scientists from the U.S. Department of Energy's (DOE) Brookhaven National Laboratory (BNL), working with colleagues from Pacific Northwest National Laboratory (PNNL), will conduct a field campaign this summer and fall in the skies over the Pacific Northwest and Tennessee to measure the evolution of aerosols in wildfires and prescribed agriculture burns, respectively.
Policymakers should be paying more, rather than less, attention to tackling climate change in economically tough times, a new study suggests. As economies have stagnated major emitters of CO2 seem unwilling to accept binding emissions reduction targets. But findings, published this week in Nature Climate Change, show the social cost of carbon dioxide is higher in a low economic growth world.
More frequent sweltering summers, droughts, flooding and extreme weather across the country are expected with our changing global climate. The problem is so severe that the Obama Administration is taking new steps to cut greenhouse gas emissions to help the nation manage the effects of climate change and to lead international climate efforts.
Study shows the atmospheric CO2 has big consequences for the tiny bacteria that are the foundation of most life in the sea
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.
