Deadly heatwaves and flooding part of emerging pattern of extremes
Blistering, record heat in the Southwest helped propel the lower 48 states to a new high-temperature record in June, with an average reading of 71.8 degrees Fahrenheit for the month. That included a new monthly temperature record set in Death Valley National Park, where the average temperature in June was 101.9 degrees Fahrenheit.
The warmest-ever June reading broke the record set during the Dust Bowl era, in 1933, according to NOAA’s National Centers for Environmental Information. The year-to-date is the third-warmest on record, the monthly state of the climate summary report said.
Above-average temperatures were widespread across the globe in February, making it another record-breaking month — with the highest departure from average on record. Combining land and ocean surface temperatures from thousands of measuring stations, NOAA announced this week that the global average temperature for the month was 2.18 degrees Fahrenheit above the 20th century average.

New vulnerability assessment to help guide fisheries management
Rapidly warming ocean temperatures off the coast of the Northeastern U.S. are likely to have a big impact on nearly all fish and other marine life in the region. Scientists with the National Oceanic and Atmospheric Administration carefully surveyed 82 species in a recent study, trying to identify which are the most vulnerable to global warming.
“Our method identifies specific attributes that influence marine fish and invertebrate resilience to the effects of a warming ocean and characterizes risks posed to individual species,” said Jon Hare, a fisheries oceanographer at NOAA Fisheries’ Northeast Fisheries Science Center (NEFSC) and lead author of the study. “This work will help us better account for the effects of warming waters on our fishery species in stock assessments and when developing fishery management measures.” Continue reading “Global warming: Goodbye to sea scallops?”→
New protection to aid recovery of rare marine mammals
North Atlantic right whales will have a little more protection off the East Coast, as NOAA’s National Marine Fisheries Service expanded critical habitat to cover feeding areas in the Gulf of Maine/Georges Bank region and southeast calving grounds from North Carolina to Florida.
Experts say no sign of slowdown in long-term warming trend
By Bob Berwyn
The average global temperature for 2015 was the warmest since record-keeping started in 1880, breaking the mark set last year by a full quarter degree, according to the latest climate update from NASA and NOAA.
Discussing the new temperature record in a telephone conference call, experts with the two agencies said 2016 could be hotter yet because of warmth stored in the oceans. There’s no sign at all that the long term global warming trend will slow down any time soon, said NASA researcher Gavin Schmidt.

Scientists track fish populations, ice extent and river discharge
Temperatures across the Arctic were the warmest on record in 2015, ranging more than 2 degrees Fahrenheit above average, according to the National Oceanic and Atmospheric Administration’s annual Arctic report card.
Released earlier this month, the report showed documents increasing air and sea surface temperatures, decreasing sea ice extent and Greenland ice sheet mass, and changing behavior of fish and walrus in the region.
