Scientists have discovered an atmospheric teleconnection that allows them to accurately predict winter precipitation in the southwestern United States by measuring summer sea surface temperatures near New Zealand.
An international research team has found an increase in high waves and winds in the ice-free waters of the Arctic Ocean, a potentially dangerous navigational tipping point for the 'new and unusual' state of the waters.
Warmer temperatures by the end of this century will dramatically increase the volatility in global supplies of corn, the most widely grown crop in the world.
Some hurricanes are moving more slowly, spending increased time over land and leading to catastrophic local rainfall and flooding, according to a new study.
Weather-related disasters can make people more religious but it depends on the toll they inflict, suggests new research. If a disaster injures a significant number of people, it can strengthen religiosity among those who are already religious. But if a disaster inflicts mostly economic damage, the opposite effect applies.
Scientists have developed a new method for generating data for ensemble simulation of extreme weather phenomena. He tested the method in simulation of a typhoon and a global warming simulation, and successfully created the necessary range of data in each case. The method has high computational stability and can be applied to any type of extreme weather event or other types of problems such as land cover change.
New research looks at how the destructive southern pine beetle reacts to cooler weather in its climate-induced, new northern ranges.
Fires ignited by lightning have and will likely continue to increase across the Mediterranean and temperate regions in the Southern Hemisphere under a warmer climate, according to a new study co-led by a Portland State University researcher.
Wild monkeys which have more social partners form larger huddles in adverse weather and have a better chance of surviving winter, new research has found. The study is the first to show that such social bonding may be connected to higher 'fitness' -- the term used by scientists to measure of how well animals can cope with their local ecological conditions, usually measured by reproductive success and survival.
Sunny California may be getting too sunny. Increasing summer temperatures brought on by a combination of intensifying urbanization and warming climate are driving off once common low-lying morning clouds in many southern coastal areas of the state, leading to increased risk of wildfires, says a new study.
Encircling Earth are two enormous rings -- called the Van Allen radiation belts -- of highly energized ions and electrons. Various processes can accelerate these particles to relativistic speeds, which endanger spacecraft unlucky enough to enter these giant bands of damaging radiation. Scientists had previously identified certain factors that might cause particles in the belts to become highly energized, but they had not known which cause dominates.
Fluvial floods will increase due to human-made climate change, in particular in China. This might raise direct and indirect economic losses along the global supply and trade chains. The US is susceptible to indirect climate-related economic losses due to its negative trade balance with China. Trump's tariffs might further reduce the resilience of the US economy.
A study offers an explanation for a mysterious and sometimes deadly weather pattern in which the jet stream, the global air currents that circle the Earth, stalls out over a region. Much like highways, the jet stream has a capacity, researchers said, and when it's exceeded, blockages form that are remarkably similar to traffic jams -- and climate forecasters can use the same math to model them both.
Ecologists have no doubt that climate change will affect the earth's animals and plants. But how exactly? This is often hard to predict. There are already indications that some species are shifting their distribution range. But it is much less clear how individual animals and populations are responding to the changes. Scientists have been studying nocturnal desert geckos to see how they are adapting to climatic changes.
A highly precise method to determine past typhoon occurrences from giant clam shells has been developed, with the hope of using this method to predict future cyclone activity.
By the late 21st century, if atmospheric greenhouse gas concentrations reach worst-case projections, Floridians could experience summer heatwaves three times more frequently, and each heatwave could last six times longer and be much hotter than at present, according to new research.
Scientists have developed a detailed analysis of how 22 recent hurricanes would be different if they formed under the conditions predicted for the late 21st century.
Experts have challenged the principle that tropical ecosystems are aseasonal -- after discovering regular cycles in fruiting, flowering and leafing in such climates.
Critically endangered South American forests thought to be the result of climate change were actually spread by ancient communities, archaeologists have found.
The UK and large parts of northern Europe could become windier if global temperatures reach 1.5 degrees C above pre-industrial levels, according to a new study.
