Heatwaves in the world's oceans have become over 20 times more frequent due to human influence. This is what researchers are now able to demonstrate. Marine heatwaves destroy ecosystems and damage fisheries.
Scientists have spotted a once-in-a-century climate anomaly during World War I that likely increased mortality during the war and the influenza pandemic in the years that followed.
Researchers can offer insight into why these storms intensified quickly as they moved across the continental shelf.
As COVID-19 cases continue to rise, it is increasingly urgent to understand how climate impacts the spread of the coronavirus, particularly as winter virus infections are more common and the northern hemisphere will soon see cooler temperatures. Researchers studied the effects of relative humidity, environmental temperature, and wind speed on the respiratory cloud and virus viability. They found a critical factor for the transmission of the infectious particles is evaporation.
The 2020 minimum extent, which was likely reached on Sept. 15, 2020 measured 1.44 million square miles (3.74 million square kilometers).
Large volcanic eruptions can help to forecast the monsoon over India - the seasonal rainfall that is key for the country's agriculture and thus for feeding one billion people. As erratic as they are, volcanic eruptions improve the predictability, a research team now finds. What seems to be a paradox is in fact due to a stronger coupling between the monsoon over large parts of South and South-East Asia and the El Niño phenomenon after an eruption.
Scientists used observations recorded by members of the public to increase accuracy of computer model predictions of when harmful CMEs will hit Earth.
The observations from Earth orbit show high-altitude concentrations of the gas that are more than 10 times typical amounts.
The fast-warming Arctic has started to transition from a predominantly frozen state into an entirely different climate with significantly less sea ice, warmer temperatures, and more rain, according to a comprehensive new study of Arctic conditions.
A new study puts an economic value on the benefit of research to improve knowledge of the biological carbon pump and reduce the uncertainty of ocean carbon sequestration estimates.
Storm surges sometimes can increase coastal sea levels 10 feet or more, jeopardizing communities and businesses along the water, but new research shows there may be a way to predict periods when it's more likely that such events occur. Researchers have developed models to predict extreme changes in sea level by linking storm surges to large-scale climate variability.
A new study finds that climate change will have a devastating effect on the greater Palm Springs area's dominant industry -- tourism. Due to climate change, the number of days above 85 degrees between November and April is projected to increase up to 150% by the end of the century.
The warm, dry summer of 2018 has left clear traces in various ecosystems. Researchers have found that if the climate continues to warm up, higher altitudes can also expect negative consequences in the future.
A researcher developed a mathematical method that shows climate change likely caused the rise and fall of an ancient civilization. A new article outlines the technique he developed and shows how shifting monsoon patterns led to the demise of the Indus Valley Civilization, a Bronze Age civilization contemporary to Mesopotamia and ancient Egypt.
A better understanding of how gravity waves in the upper atmosphere interact with the jet stream, polar vortex and other phenomena could be key to improved weather predictions and climate models.
Caught in an Atlantic hurricane, satellite-tagged loggerhead turtles changed their dive behavior and movement patterns as the storm passed. The tags also recorded changes in the environment.
Foundational science has discovered the molecular structure of plant enzymes that could be manipulated to create flood-resistant crops, vital as weather events become more extreme due to global warming.
Researchers found a correlation between words used in media coverage related to weather or air quality, and transit ridership. It's not enough yet to say that media coverage causes changes in ridership. But it's enough to explore what factors in to a person's decision to ride transit and whether that decision can be nudged.
Natural disasters alone are not enough to motivate local communities to engage in climate change mitigation or adaptation, a new study has found. Rather, policy change in response to extreme weather events appears to depend on a combination of factors, including fatalities, sustained media coverage, the unusualness of the event and the political makeup of the community.
A new study revealed that correctly simulating ocean current variations hundreds of feet below the ocean surface - the so-called Pacific Equatorial Undercurrent - during El Niño events is key in reducing the uncertainty of predictions of future warming in the eastern tropical Pacific.
