Study suggests La Niña winters could keep on coming
Forecasters are predicting a “three-peat La Niña” this year. This will be the third winter in a row that the Pacific Ocean has been in a La Niña cycle, something that’s 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 Niñas.

‘Dangerous’ and ‘extremely dangerous’ heat stress to become more common by 2100
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.

Planting trees in pastureland provides significant cooling in the tropics
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 University of Washington puts tangible numbers to the cooling effects of this practice.

Deforestation, climate change linked to more worker deaths and unsafe conditions
Outdoor workers in the world’s 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 University of Washington and Indonesia’s Mulawarman University. In the study, researchers found that increased temperatures of 0.95 C (1.7…

Warmer climate will dramatically increase the volatility of global corn crops
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.

Rapid decline of Arctic sea ice a combination of climate change and natural variability
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.

Global warming not just a blanket – in the long run, it’s more like tanning oil
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.

Greenland melting due equally to global warming, natural variations
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.

Embarking on geoengineering, then stopping, would speed up global warming
Carrying out geoengineering for several decades and then stopping would cause warming at a rate more than double that expected due to global warming.
