With much of the central plains and Midwest now entering peak tornado season, the impact of these potentially devastating weather events will be shaped in large part by how individuals think about and prepare for them. A new study shows that people's past experiences with tornadoes inform how they approach this type of extreme weather in the future, including their perception of the risk.

New research provides evidence that a key cog in the global ocean circulation system hasn't been running at peak strength since the mid-1800s and is currently at its weakest point in the past 1,600 years. If the system continues to weaken, it could disrupt weather patterns from the United States and Europe to the African Sahel, and cause more rapid increase in sea level on the US East Coast.

Silent marine robots that record sounds underwater are allowing researchers to listen to the oceans as never before. While pilot whales make whistles, buzzes and clicks, pods of hunting dolphins create high-pitched echolocation clicks and larger species such as sperm whales make louder, slower clicks. As well as eavesdropping on marine life, the recordings can be used to measure sea-surface wind speed and monitor storms. The research will be presented at the General Assembly of the European Geosciences Union, Vienna.

Large-scale weather cycles, such as the one related to the El Niño phenomenon, affect two-thirds of the world's cropland. In these so called climate oscillations, air pressure, sea level temperature or other similar factors fluctuate regularly in areas far apart in a way that causes rain and temperature patterns to shift significantly.

Melting icecaps, mass flooding, megadroughts and erratic weather are no laughing matter. However, a new study shows that humor can be an effective means to inspire young people to pursue climate change activism. At the same time, fear proves to be an equally effective motivator and has the added advantage of increasing people's awareness of climate change's risks.

In the midst of an unseasonably warm winter in the Pacific Northwest, a comparison of four publicly available climate projections has shown broad agreement that the region will become considerably warmer in the next century if greenhouse gas concentrations in the atmosphere rise to the highest levels projected in the the Intergovernmental Panel on Climate Change (IPCC) 'business-as-usual' scenario.

Overwhelming scientific evidence has demonstrated that our planet is getting warmer due to climate change, yet parts of the eastern US are actually getting cooler. According to a new study, the location of this anomaly, known as the 'US warming hole,' is a moving target. During the winter and spring, the US warming hole sits over the Southeast, as the polar vortex allows arctic air to plunge into the region, resulting in persistently cooler temperatures.

Bats spend every night hard at work for local farmers, consuming over half of their own weight in insects, many of which are harmful agricultural pests, such as the noctuid moths, corn earworm and fall armyworm. And now they are arriving earlier in the season, and some of them are reluctant to leave. It seems the bats know more about climate change than we had realized.

Just one phenomenon may underlie all solar eruptions. Researchers have identified the presence of a confining 'cage' in which a magnetic rope forms, causing solar eruptions. It is the resistance of this cage to the attack of the rope that determines the power and type of the upcoming flare. This work has enabled the scientists to develop a model capable of predicting the maximum energy that can be released during a solar flare.

Weather forecasters could be able to better predict regional rainfall and temperatures by using North Atlantic jet stream data, according to new research. Climate scientists examined the relationship between changes in North Atlantic atmospheric circulation -- or jet stream -- and UK regional weather variations during summer and winter months over the past 65 years, and found that the jet stream changes were significantly associated with variations in regional rainfall and temperatures.

Tiny particles fuel powerful storms and influence weather much more than has been appreciated, according to a new study. While scientists have known that aerosols may play an important role in shaping weather and climate, the new study shows that the smallest of particles have an outsize effect. The tiny pollutants -- long considered too small to have much impact on droplet formation -- are, in effect, diminutive downpour-makers.

The warming climate is expected to affect coastal regions worldwide as glaciers and ice sheets melt, raising sea level globally. For the first time, an international team has found evidence of how sea-level rise already is affecting high and low tides in both the Chesapeake and Delaware bays, two large estuaries of the eastern United States.

Global surface temperatures surged by a record amount from 2014 to 2016, boosting the total amount of warming since the start of the last century by more than 25 percent in just three years, according to a new University of Arizona-led paper. The research is the first to quantify the record temperature spike of an additional 0.43 degrees F (0.24 C) in just three years and to identify the fundamental reason for the jump.

Climbing a mountain is challenging. So, too, is providing the best possible information to plan for climate change's impact on mountain vegetation and wildlife. Scientists show that using several sources of climate measurements when modeling the potential future distributions of mountain vegetation and wildlife can increase confidence in the model results and provide useful guidance for conservation planning.

As farmers in the American West decide what, when and where to plant, and urban water managers plan for water needs in the next year, they want to know how much water their community will get from melting snow in the mountains. This melting snow comes from snowpack, the high elevation reservoir of snow which melts in the spring and summer. New NOAA research is showing we can predict snow levels in the mountains of the West in March some eight months in advance.

When deciding which sweet corn hybrids to plant, vegetable processors need to consider whether they want their contract growers using a workhorse or a racehorse. Is it better to choose a hybrid with exceptional yields under ideal growing conditions (i.e., the racehorse) or one that performs consistently well across ideal and less-than-ideal conditions (i.e., the workhorse)? New research suggests the workhorse is the winner in processing sweet corn.

Water contaminated by the oil currently leaking into the ocean from the Sanchi tanker collision is likely to take at least three months to reach land, and if it does the Korean coast is the most likely location. However, the oil's fate is highly uncertain, as it may burn, evaporate, or mix into the surface ocean and contaminate the environment for an extended duration.

Increased fluctuations in the path of the North Atlantic jet stream since the 1960s coincide with more extreme weather events in Europe such as heat waves, wildfires and flooding. The new research is the first reconstruction of historical changes in the North Atlantic jet stream prior to the 20th century. By using tree rings, the researchers developed a historical look at the position of the North Atlantic jet back to 1725.
