Severe snowy weather in winter or extreme rains in summer in the UK might be influenced by warming trends in the Arctic, according to new findings. 

Last year was the second hottest year on record worldwide, behind 2016, according to a European Union climate monitoring program. Global temperatures averaged 14.7 degrees Celsius (58.46°F) — 1.2 degrees C (2.2°F) above pre-industrial times.

Scientists have found surprising evidence of rapid climate change in the Arctic: In the middle of the Arctic Ocean near the North Pole, they discovered that the levels of radium-228 have almost doubled over the last decade.

There is a new way to measure the average temperature of the ocean thanks to researchers at Scripps Institution of Oceanography at the University of California San Diego. In an article published in the Jan. 4, 2018, issue of the journal Nature, geoscientist Jeff Severinghaus and colleagues at Scripps Oceanography and institutions in Switzerland and Japan detailed their ground-breaking approach.

Large areas of the Earth’s surface are experiencing rising maximum temperatures, which affect virtually every ecosystem on the planet, including ice sheets and tropical forests that play major roles in regulating the biosphere, scientists have reported.

NASA’s Aqua satellite passed over the South China Sea and obtained a visible light image of the first depression of the Northwestern Pacific Ocean basin’s 2018 tropical cyclone season. Vertical wind shear can be deadly to tropical cyclones and satellite data showed Tropical Depression Bolaven, formerly known as 01W, was being adversely affected by it.

NASA-NOAA's Suomi NPP passed over newly formed Tropical Storm Ava and analyzed the storm in infrared light. Ava, the third tropical cyclone of the Southern Indian Ocean season formed off the coast of northeastern Madagascar on Jan. 3. 

A new report from the National Academies of Sciences, Engineering, and Medicine calls for an international, multi-institutional comprehensive campaign of research, observation, and analysis activities that would help improve understanding and prediction of the Gulf of Mexico’s Loop Current System (LCS).  The position, strength, and structure of the LCS -- the dominant ocean circulation feature in the Gulf -- has major implications for oil and gas operations, hurricane intensity, coastal ecosystems, oil spill response, the fishing industry, tourism, and the region’s economy. 

 

In 1870, explorer Adolf Erik Nordenskiöld, trekking across the barren and remote ice cap of Greenland, saw something most people wouldn’t expect in such an empty, inhospitable landscape: haze.

Climate scientists often warn that rising CO2 levels in the atmosphere will cause an increase in the number and intensity of heat waves in many regions of the world. But a new study is cautioning that climate change will also significantly increase humidity, magnifying the effects of these heat waves and making it more difficult for humans to safely work or be outside.
