Socio-economic activities in the present world have become increasingly interdependent because of rapid technological progress, urbanization, and globalization. Because of these interdependencies between human society and natural ecosystems, climate impacts on one sector may influence other sectors, including seemingly remote ones, which we call “interconnections of climate risks”. While a substantial number of climate risks…

The greatest advances were found among short-distance migrants that winter in Europe or North America: about 1.5-2 days per decade. Long-distance migrants that winter in the tropics have also advanced the start of their migration, but only by approximately 0.6-1.2 days per decade. “Based on changes in median migration dates, birds have on average advanced…

On the mountain slopes of the western United States, climate can play a major role in determining which tree communities will thrive in the harshest conditions, according to new work from Carnegie’s Leander Anderegg and University of Washington’s Janneke Hille Ris Lambers. Their findings, published in Ecology Letters, are an important step in understanding how…

The Sahel is a semi-arid region of transition in Africa between the Sahara and the Sudanian Savanna, which is extremely sensitive to the precipitation change. This vulnerable region is known for regular severe droughts and megadroughts, leading to large-scale famine. Thus, confident model projections of Sahel precipitation change under global warming is essential. However, current…

Few headlines were sparked by food crises that ravaged Madagascar, Ethiopia and Haiti. Sven Harmeling, the climate change lead for Care International, which commissioned the report, said: “Not only are the people who live in the world’s poorest countries most vulnerable to climate change, but they are also the least equipped to address its increasing…

A major focus in conservation is acquiring forests – often at great expense – to expand the network of thousands of protected areas around the world. But conservationists cannot simply designate an area as “protected” and assume all species within the area will remain there, according to the study in Biodiversity and Conservation, which focused…

Airborne Wind Energy Systems (AWES) are a new kind of technology to harvest wind energy. The expensive and heavy tower and rotor of a conventional wind turbine are here substituted by a light tether and an aircraft (flexible giant kites or large drones), respectively. In the so-called ground generation scheme, AWES use the tension force…

Scientists report that rising global temperatures, particularly in the Arctic, are redistributing the energy in the atmosphere: More energy is available to fuel thunderstorms and other local, convective processes, while less energy is going toward summertime extratropical cyclones — larger, milder weather systems that circulate across thousands of kilometers. These systems are normally associated with…

In their research, the Crowther Lab uses the largest global dataset of forest inventory data (the Global Forest Biodiversity Initiative), measured by people on the ground in over 1.2 million locations around the world combined with satellite observations, to get a mechanistic understanding of the global forest system. The lab also uses an equivalent database…

Some argue that activities at the U.S. Southern border pose a grave threat to American lives. Statements from the Pentagon and other sources offer alternative perspectives on how “dire” things really are at the border. Experts estimate that between 445 and 600 homicides (not multiple thousands as claimed) were killed by undocumented immigrants in 2018….
