2018's Four Corners drought directly linked to human-caused climate change

23. Jaanuar 2020 - 22:26
The western United States has experienced such intense droughts over the past decade that technical descriptions are becoming inadequate. In many places, conditions are rocketing past "severe," through "extreme," all the way to "exceptional drought."

Despite less ozone pollution, not all plants benefit

22. Jaanuar 2020 - 22:43
Policies and new technologies have reduced emissions of precursor gases that lead to ozone air pollution, but despite those improvements, the amount of ozone that plants are taking in has not followed the same trend, according to researchers.

NASA, NOAA analyses reveal 2019 second warmest year on record

15. Jaanuar 2020 - 20:04
According to independent analyses by NASA and the National Oceanic and Atmospheric Administration (NOAA), Earth's global surface temperatures in 2019 were the second warmest since modern recordkeeping began in 1880.

Historical housing disparities linked with dangerous climate impacts

14. Jaanuar 2020 - 17:17
Extreme heat kills more people in the United States than any other type of hazardous weather and will likely become even deadlier due to climate change. However, extreme heat does not affect all people equally.

Climate change increases the risk of wildfires confirms new review

14. Jaanuar 2020 - 14:40
Human-induced climate change promotes the conditions on which wildfires depend, increasing their likelihood -- according to a review of research on global climate change and wildfire risk.

Future subtropical warming accelerates tropical climate change

13. Jaanuar 2020 - 19:45
In response to future fossil fuel burning, climate computer models simulate a pronounced warming in the tropical oceans. This warming can influence the El Niño phenomenon and shift weather and rainfall patterns across the globe. Despite being robustly simulated in computer models of the climate system, the origin of this accelerated tropical warming has remained a mystery. A new study concludes that climate change outside the tropics is the main culprit.

Cracks in Arctic sea ice turn low clouds on and off

10. Jaanuar 2020 - 14:37
The prevailing view has been that more leads are associated with more low-level clouds during winter. But an atmospheric scientists noticed something strange in their study of these leads: when lead occurrence was greater, there were fewer, not more clouds.

Evolving landscape added fuel to Gobi Desert's high-speed winds

8. Jaanuar 2020 - 20:17
A new study finds that the dark, rocky landscape of the Hami basin in the Gobi Desert helped to make it one of the windiest places in China.

Antarctic waters: Warmer with more acidity and less oxygen

6. Jaanuar 2020 - 19:20
The increased freshwater from melting Antarctic ice sheets plus increased wind has reduced the amount of oxygen in the Southern Ocean and made it more acidic and warmer, according to new research.

Climate signals detected in global weather

2. Jaanuar 2020 - 21:34
Searched for and found: climate researchers can now detect the fingerprint of global warming in daily weather observations at the global scale. They are thus amending a long-established paradigm: weather is not climate -- but climate change can now be detected in daily weather.

Climate change impacted Hurricane Florence's precipitation and size

2. Jaanuar 2020 - 21:34
A new modeling framework showed that Hurricane Florence produced more extreme rainfall and was spatially larger due to human-induced climate change.

Scientists link La Niña climate cycle to increased diarrhea

30. Detsember 2019 - 17:47
A study finds that spikes in cases of life-threatening diarrhea in young children are associated with La Niña climate conditions. The findings could provide the basis for an early-warning system that would allow public health officials to prepare for periods of increased diarrhea cases as long as seven months ahead of time.

Preparing for extreme sea levels depends on location, time

18. Detsember 2019 - 16:02
Using historical data from tide gauges that line US coasts, researchers created an extreme sea level indicator that identifies how much of a role different major weather and ocean forces have played in affecting extreme sea levels in coastal areas around the country.

In ancient Scottish tree rings, a cautionary tale on climate, politics and survival

17. Detsember 2019 - 21:15
Using old tree rings and archival documents, historians and climate scientists have detailed an extreme cold period in Scotland in the 1690s that caused immense suffering. It may have lessons for Brexit-era politics.

Applying physics principle yields grim prediction on hurricane destruction in era of global warming

17. Detsember 2019 - 21:15
Global warming could well lead to hurricanes more powerful than meteorologists currently forecast. A physicist noticed that one of the principles of physics -- phase transition -- did not appear in the scientific literature of meteorology. Using 60 years of published data, he demonstrated that the destructive power of tropical hurricanes increased linearly and rapidly as water temperature increased. The destructive energy could therefore treble if water temperatures rise by 2 degrees.

Birds' seasonal migrations shift earlier as climate changes

17. Detsember 2019 - 0:36
In what the authors believe is one of the first studies to examine climate change impact on the timing of bird migration on a continental scale, researchers report that spring migrants were likely to pass certain stops earlier now than they would have 20 years ago. Also, temperature and migration timing were closely aligned, with the greatest changes in migration timing occurring in the regions warming most rapidly. Timing shifts were less apparent in fall, they add.

Climate cycles and insect pests drive migration timing of reindeer's North American cousin

12. Detsember 2019 - 22:33
Biologists have discovered two unexpected drivers for migration timing that dispute long-held assumptions and provide insight into potential future effects of climate change on caribou. First, the start of migration is synchronized across North America and tied to large-scale, ocean-driven climate cycles. Second, warm, windless summers that favored insect pests lead to poorer maternal health and delayed arrivals at the calving grounds the following spring.
