In only 25 years, ocean melting has caused ice thinning to spread across West Antarctica so rapidly that a quarter of its glacier ice is now affected, according to a new study.
An enormous volcanic eruption on Iceland in 1783-84 did not cause an extreme summer heat wave in Europe. But, as Benjamin Franklin speculated, the eruption triggered an unusually cold winter, according to a new study. The study will help improve predictions of how the climate will respond to future high-latitude volcanic eruptions.
Coral experts around the world said it was impossible to extract a multi-century record of El Niño events. But now a persistent effort has produced the world's first 400-year long record of El Niño events. And the changes researchers have found to El Niños in recent decades are startling.
Climate change has raised the risk of a fungal disease that ravages banana crops, new research shows.
Rapeseed growers are losing up to a quarter of their crop yield each year because of temperature rises during an early-winter weather window.
A new air quality forecasting system has begun providing reliable forecasts of fine particulate matter for residents of New Delhi and other heavily polluted areas of India. The technology may be adapted for air quality forecasts in the US and other parts of the world.
Recent flooding in the Midwest has brought attention to the complex agricultural problems associated with too much rain. Data from the past three decades suggest that excessive rainfall can affect crop yield as much as excessive heat and drought. In a new study, an interdisciplinary team linked crop insurance, climate, soil and corn yield data from 1981 through 2016.
A new study shows that beyond the benefits of reduced extreme weather in the long term, global mitigation efforts would also lower oil prices in coming decades, resulting in a significant economic boon for most poorer countries.
Although the particulate matter that filled the winter skies resulted from both human and natural emissions, a new study concludes that human-caused climate change played only a minor role in the air's stagnation.
Researchers studying hi-res satellite imagery have discovered that emperor penguins at the Halley Bay colony in the Weddell Sea have failed to raise chicks for the last three years.
Geography researchers found that temperature was a better predictor of wildfire than humidity, rainfall, moisture content of the vegetation and soil and other weather factors.
On March 17, 2002, the satellite duo GRACE was launched to map the Earth's gravity field more precisely than ever before. The measurements make it possible to monitor the terrestrial water cycle, the mass balance of ice sheets and glaciers or changes in sea levels. This helps to better understand important trends in the global climate system.
Hurricane Maria dropped more rain on Puerto Rico than any storm to hit the island since 1956, a feat due mostly to the effects of human-caused climate warming, new research finds.
When it comes to understanding future climate, the south Asian summer monsoon offers a paradox. Most climate models predict that as human-caused global warming increases, monsoon rain and wind will become more intense -- but weather data collected in the region shows that rainfall has actually declined over the past 50 years.
In the future, weather forecasts that provide storm warnings and help us plan our daily lives could come up to five days sooner before reaching the limits of numerical weather prediction, scientists said.
A new study concludes that exposure to extreme heat and precipitation in prenatal and early childhood years in countries of the global tropics could make it harder for children to attain secondary school education, even for better-off households.
The North Atlantic warming hole (NAWH), a region of reduced warming located in the North Atlantic Ocean, significantly affects the North Atlantic jet stream in climate simulations of the future.
When heavy rain falls over the Indian Ocean and Southeast Asia and the eastern Pacific Ocean, it is a good indicator that temperatures in central California will reach 100°F in four to 16 days.
Researchers used both linear stability theory and direct numerical simulations to uncover, for the first time, fluid instabilities in the Prandtl model for katabatic slope flows. Not only will this discovery be important for agriculture, aviation and weather prediction, but it will also be vital for climate change research and associated sea-level rise, as accurate prediction of katabatic surface wind profiles over large ice sheets and glaciers is critical in energy balance of melting ice.
New research shows that the Larsen C ice shelf -- the fourth largest ice shelf in Antarctica -- experienced an unusual spike in late summer and early autumn surface melting in the years 2015 to 2017. The study, spanning 35 years from 1982 to 2017, quantifies how much of this additional melting is due to warm, dry air currents called foehn winds that originate high in the peninsula's central mountain range.
