New research suggests that even as rising carbon dioxide levels in the atmosphere drive the climate toward warmer temperatures, the weather will remain predictable.
Researchers report a breakthrough in making accurate predictions of weather weeks ahead. They've created an empirical model fed by careful analysis of 37 years of historical weather data. Their model centers on the relationship between two well-known global weather patterns: the Madden-Julian Oscillation and the quasi-biennial oscillation.
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.
The Paris Agreement has aspirational goals of limiting temperature rise that won't be met by current commitments. That difference could make the world another degree warmer and considerably more prone to extreme weather.
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.
Scientists agree that changes in land use such as deforestation, not just emissions of greenhouse gases, can play a significant role altering the world's climate systems. Now, a new study reveals how another type of land use, intensive agriculture, can impact regional climate.
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.
New multi-scale relief modelling algorithm helps archaeologists rediscover topographical features of the past.
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.
A new study identifies a method for predicting the likelihood of damaging hailstorms in the United States -- up to three weeks in advance.
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.
New research that analyzed more than 270 million years of data on animals shows that mammals and birds -- both warm-blooded animals -- may have a better chance of evolving and adapting to the Earth's rapidly changing climate than their cold-blooded peers, reptiles and amphibians.
A new study by civil and environmental engineers delves into the 2015 Wimberley, Texas floods that destroyed 350 homes and claimed 13 lives. Scientists researched the factors that led to the catastrophic flooding and shed light on new ways people in flood-prone areas can protect against future tragedies.
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.
The overprescribing of opioid-based painkillers may be the main driver of the increased abuse of opioids in rural America, but economists say that other factors, including declining farm income, extreme weather and other natural disasters, may affect a crisis that is killing thousands of citizens and costing the country billions of dollars.
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.
Continuing the planet's long-term warming trend, globally averaged temperatures in 2017 were 1.62 degrees Fahrenheit (0.90 degrees Celsius) warmer than the 1951 to 1980 mean, according to scientists.
