Every four years Congress is provided with a state-of-the-art report on the impacts of climate change on the United States. The next National Climate Assessment is scheduled for 2018, but its scientific findings are scheduled to be published today. Here, two of its authors explain what to expect.
Human-influenced climate warming has already reduced rainfall and increased evaporation in the Mideast, worsening water shortages. Up to now, climate scientists had projected that rainfall could decline another 20 percent by 2100. But the Dead Sea cores suggest that things could become much worse, much faster.
A thousand years ago, powerful Viking chieftans flourished in Norway’s Lofoten Islands, above the Arctic Circle. In an environment frequently hovering on the edge of survivability, small shifts in climate or sea level could mean life or death. People had to constantly adapt, making their living from the land and the sea as best they could.
The rise of the Vikings was not a sudden event, but part of a long continuum of human development in the harsh conditions of northern Scandinavia. How did the Vikings make a living over the long term, and what might have influenced their brief florescence? Today, their experiences may provide a kind of object lesson on how changing climate can affect civilizations.
Climate change could turn one of Africa’s driest regions wet, according to a new study. Scientists have found evidence in computer simulations for a possible abrupt change in the Sahel, a region long characterized by aridity and political instability. In the study, just published in the journal Earth System Dynamics, the authors detected a self-amplifying… read more
As the world warms due to human-induced climate change, many scientists have been projecting that global rainfall patterns will shift. In the latest such study, two leading researchers map out how seasonal shifts may affect water resources across the planet.
After helping Chris an Dan with soil salinity and reflectance measurement, Humayun, Liz and I moved onto the smaller M.B. Mewl to sail through the Sundarban Mangrove Forest to service our GPS station at Hiron Point.
I’m back in Bangladesh with a small team after a year and a half away. One different is a police escort as a result of the attacks last year. We start by successfully sampling river sediments to correct the date of an earthquake that caused a river to shift over 3,500 years ago. We also will be fixing broken equipment, visiting the ever changing rivers and hopefully meeting with the public and government officials about the earthquake hazard.
Climate Week NYC 2016, Sept. 19 to 35, features over 70 events bringing together business, societal and government leaders to share ideas, technologies, resources and success stories that are helping to curb climate change and transition to a low-carbon society.
