Methane-eating microbes in the ocean help moderate Earth’s temperature

Methane-eating microbes in the ocean help moderate Earth’s temperature

Science
June 14 (UPI) -- Methane-eating microbes in the planet's oceans play an unappreciated role moderating Earth's temperature, according to a new study published Monday in the journal Proceedings of National Academy of Sciences. Carbon dioxide is the most abundant and famous greenhouse gas, but methane is plentiful and its warming effect is more than 30 times more powerful. Most methane that ends up in the atmosphere is released by human activities, but several natural processes also produce methane: volcanic activity, subsurface water-rock interactions and microbial metabolism. The majority of naturally produced methane on Earth is produced by microbes, and much of that is in the ocean. Over the last decade or so, a number of studies have shown the planet's oceans to be home to a lot more me...
‘Hottest temperature on Earth’ as Death Valley, US hits 54.4C

‘Hottest temperature on Earth’ as Death Valley, US hits 54.4C

Science
'Hottest temperature on Earth' recorded in USWhat could be the highest temperature ever reliably recorded on Earth - 130F (54.4C) - has been reached in Death Valley National Park in California. The recording is being verified by the US National Weather Service.It comes amid a heatwave on the US's west coast, where temperatures are forecast to rise further this week.The scorching conditions have led to two days of blackouts in California, after a power plant malfunctioned on Saturday.What were the previous records?Sunday's reading was recorded in Furnace Creek in Death Valley.Before this, the hottest temperature reliably recorded on Earth was 129.2F (54C) - also in Death Valley in 2013.A higher reading of 134F, or 56.6C a century ...

Meteorologists report that Earth's warming ties a record level for MayBy BY SETH BORENSTEIN AP Science WriterJune 12, 2020, 9:30 PM2 min read2 min readShare to FacebookShare to TwitterEmail this article Earth's temperature spiked to tie a record high for May, U.S. meteorologists reported Friday. Last month the global average temperature was 60.3 degrees (15.7 degrees Celsius), tying 2016 for the hottest May in 141 years of record keeping, according to the National Oceanic and Atmospheric Administration. That's 1.7 degrees (nearly 1 degree Celsius) higher than the 20th century average for Earth. Temperature on land set a heat record, while ocean temperatures ranked second. Parts of Africa, Asia, western Europe, South and Central America had record warmth. “We continue to warm on t...

Earth’s temperature spiked to tie with record for May last month

Technology
The temperature of the Earth spiked last month to tie with the record high for May, US meteorologists reported.The global average temperature was 15.7C meaning it was equal to that of May 2016, according to the National Oceanic and Atmospheric Administration (NOAA). The two months were the hottest months of May in 141 years of record keeping, the administration added.They were nearly 1C higher than the 20th century average for Earth.Temperature on land set a heat record, while ocean temperatures ranked second.

Changes in oxygen, temperature could reshape deep sea fish communities

Changes in oxygen, temperature could reshape deep sea fish communities

Science
March 5 (UPI) -- The size and complexity of marine ecosystems make it difficult to predict the effects of climate change, especially on deep sea communities. But thanks to the efforts of a team of marine biologists and oceanographers, scientists are gaining a better understanding of the influence of oxygen and temperature on the density and diversity of deep sea fish populations. The study, led by scientists with the Scripps Institution of Oceanography at the University of California San Diego and the Monterey Bay Aquarium Research Institute, focused on demersal fish communities in the Gulf of California. Demersal fish are fish that live close to the seafloor. Their data and observations showed fish diversity dramatically declines in regions with very low levels of oxygen, concentrations...
