The new Arctic Now product shows with one picture the extent of the area in the Northern Hemisphere currently covered by ice and snow. This kind of information, which shows the accurate state of the Arctic, becomes increasingly important due to climate change.
A growing network of lakes on the Greenland ice sheet has been found to drain in a chain reaction that speeds up the flow of the ice sheet, threatening its stability.
Scientists have linked the frequency of extreme winter weather in the United States to Arctic temperatures.
Researchers are launching new web-based 'report cards' to monitor and forecast changes in sea level at 32 localities along the US coastline from Maine to Alaska. They plan to update the report cards in January of each year, with projections out to the year 2050.
Measurements of the three-dimensional structure of Earth, as opposed to the one-dimensional models typically used, can help scientists more accurately determine which areas of the United States are most vulnerable to blackouts during hazardous geomagnetic storms.
Global climate is a tremendously complex phenomenon, and researchers are making painstaking progress, year by year, to try to develop ever more accurate models. Now, an international group using the powerful K computer, have for the first time accurately calculated the effects of aerosols on clouds in a climate model.
The same satellites that identify severe weather can help save you from it. NOAA's GOES series satellites carry a payload supported by NASA's Search and Rescue (SAR) office, which researches and develops technologies to help first responders locate people in distress worldwide, whether from a plane crash, a boating accident or other emergencies.
2017 was one of the worst years on record for fires in Europe, with over 800,000 hectares of land burnt in Portugal, Italy and Spain alone.
A new study of long-term snow monitoring sites in the western United States found declines in snowpack at more than 90 percent of those sites -- and one-third of the declines were deemed significant.
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.
The United States could reliably meet about 80 percent of its electricity demand with solar and wind power generation, according to scientists.
Researchers have developed a new statistical understanding of how turbulent flows called mesoscale eddies dissipate their energy, which could be helpful in creating better ocean and climate models.
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.
