Forecasters are predicting a 鈥渢hree-peat La Ni帽a鈥� this year. This will be the third winter in a row that the Pacific Ocean has been in a La Ni帽a cycle, something that鈥檚 happened only twice before in records going back to 1950. A new study of temperature patterns in the tropical Pacific Ocean suggests that climate change is, in the short term, favoring La Ni帽as.
A new study projects the number of days with “dangerous” and “extremely dangerous” mixtures of heat and humidity by the end of this century. Even if global warming is limited to 2 degrees Celsius, results show that deadly heat waves will become much more common in the mid-latitudes, and many tropical regions will experience “dangerous” heat for about half the year.
Farmers struggling to adapt to rising temperatures in tropical regions can unleash the benefits of natural cooling, alongside a host of other wins, simply by dotting more trees across their pasturelands. For the first time, a study led by the 91探花 puts tangible numbers to the cooling effects of this practice.
Outdoor workers in the world鈥檚 lower-latitude tropical forests may face a greater risk of heat-related deaths and unsafe working conditions because of deforestation and climate warming, according to a study led by The Nature Conservancy, the 91探花 and Indonesia鈥檚 Mulawarman University. In the study, researchers found that increased temperatures of 0.95 C (1.7 F) in the deforested areas of Berau Regency, Indonesia, between 2002 and 2018 were linked to roughly 118 additional deaths in 2018, and 20 additional…
Four 91探花 faculty members have been inducted into the American Academy of Arts & Sciences.
A study of global maize production in 2100 shows dramatic increases in the variability of corn yields from one year to the next under climate change, making simultaneous low yields across multiple high-producing regions more likely, which could lead to price hikes and global shortages.
Dramatic declines in Arctic sea ice during the past four decades are due to a mixture of global warming and a natural decades-long hot spot over Greenland.
Instead of carbon dioxide, or CO2, creating a blanket that slowly warms the planet, long-term warming happens because a darker surface and more moist air can absorb more of the incoming rays.
91探花atmospheric scientists David Battisti and Qiang Fu have been elected fellows of the American Geophysical Union.
Up to half of the recent warming in Greenland and surrounding areas may be due to climate variations that originate in the tropical Pacific and are not connected with the overall warming of the planet. Still, at least half the warming remains attributable to global warming caused by rising carbon dioxide emissions.
Carrying out geoengineering for several decades and then stopping would cause warming at a rate more than double that expected due to global warming.
