Report includes focus on the advance of rapid attribution methods

BOSTON (AMS PR) – Failed monsoon rains that reignited the southwestern US drought, massive flooding in central China, a spring heat wave in western Europe, and Siberian wildfires were some of the extreme weather events made more likely by human-caused climate change in 2020, according to new research published today in the Bulletin of the American Meteorological Society (BAMS).

New research reinforces consensus that humans have created a new climate

SILVER SPRING, Md. (NOAA PR) — Failed monsoon rains that reignited the southwestern U.S. drought. A spring heat wave in western Europe. Intense Siberian wildfires. Scientists say human-caused climate change made these extreme weather events more likely, according to new research published today in the Bulletin of the American Meteorological Society (BAMS).

Chairwoman Johnson and Ranking Member Lucas Call for Standards to Avoid Spectrum Interference

Eddie Bernice Johnson

WASHINGTON (House Science Committee PR) — Today, Chairwoman Eddie Bernice Johnson (D-TX), along with Ranking Member Frank Lucas (R-OK), sent letters to the Commissioners of the Federal Communications Commission (FCC) expressing concerns about out-of-band emission (OOBE) limits to protect the integrity of global weather forecasting, satellite-based climate measurements, and ground-based radio astronomy observations in the 23.6-24 GHz band.

“We urge the FCC to modify section 30.203 of its rules to fully conform its domestic OOBE limits for the 24 GHz band with the international limits articulated in Resolution 750,” said Chairwoman Johnson and Ranking Member Lucas in the letter. “We also ask that FCC pay particular attention to the docket filings by the National Telecommunications and Information Administration, National Academies’ Committee on Radio Interference, American Meteorological Society, American Geophysical Union, and National Weather Association on implementation questions that would have a significant impact on reducing the threat of harmful interference with passive earth science observations.”

The Chair and Ranking Member continued, “We thank you for examining these technical questions carefully in its efforts to craft a final rule that is adequately protective of Earth Exploration Satellite Service (EESS).  The issues associated with the 24 GHz band are not unique. The FCC is considering spectrum auctions that could affect other bands currently protected for scientific purposes and used by federal agencies.”
