As countries around the world race to mitigate global warming by limiting carbon dioxide emissions, an unlikely source could be making climate goals harder to achieve without even deeper cuts in greenhouse gas production: reductions in air pollution.
A new study reports that the deceleration in global warming observed toward the end of the past century was due to a fall in malaria transmission in the Ethiopian highlands.
The mountain forests of Tanzania are more than 9,300 miles away from Salt Lake City, Utah. But, as in eastern Africa, the wild places of Utah depend on a diversity of birds to spread seeds, eat pests and clean up carrion. Birds keep ecosystems healthy. So if birds in Tanzania are in trouble in a warming climate, as found in a recent study by University of Utah researchers, people in Utah as well as in the African tropics should pay attention.
The slowdown in global warming that was observed at the end of last century was reflected by a decrease in malaria transmission in the Ethiopian highlands, according to a study led by the Barcelona Institute for Global Health (ISGlobal), an institution supported by "la Caixa" Foundation, and the University of Chicago. The results, published in Nature Communications, underscore the close connection between climate and health.
Microscopic fossilized shells are helping geologists reconstruct Earth's climate during the Paleocene-Eocene Thermal Maximum (PETM), a period of abrupt global warming and ocean acidification that occurred 56 million years ago.
A group of climate scientists analyzing a wide range of climate modeling experiments have found that volcanic eruptions, and not natural variability, caused an evident “Atlantic Multidecadal Oscillation,” a so-called cycle of warming considered to have taken place for about 40 to 60 years during the pre-industrial era.
Nokia today announced that it will reduce emissions by 50% across both its own operations and products in use by 2030. The company’s new Science Based Targets (SBTs) fulfill its commitment to recalibrate in line with a 1.5°C global warming scenario.
Climate experts have revealed that rising temperatures will intensify future rainfall extremes at a much greater rate than average rainfall, with largest increases to short thunderstorms.
Land stores vast amounts of carbon, but a new study led by Cranfield University's Dr Alice Johnston suggests that how much of this carbon enters the atmosphere as temperatures rise depends on how far that land sits from the equator.
Under the 2015 Paris Agreement, the United Nations Framework Convention on Climate Change agreed to pursue efforts to limit the temperature increase to 2.0 °C and, ideally, to 1.5 °C, over preindustrial levels. However, even before that treaty was signed, scientists had already warned that those "best case" targets were unlikely to be achievable. Consequently, many fire weather studies are built with models that simulate much higher levels of climate warming.
