Coral bleaching threat persists in Southern Hemisphere

Uptick in tropical cyclones intensifies impacts, hampers recovery

lk;
A recent update from NOAA’s coral watch program shows that many reefs in the Southern Hemisphere face potential bleaching events in the next several months.

Staff Report

Along with the widely reported bleaching threat from over-heated oceans, coral reefs in many parts of the world also may have to cope with intensifying tropical storms, which could make it even more difficult for them to survive the Anthropocene.

New research published in the journal Global Change Biology looked at whether predicted increases in cyclone intensity might change the nature of coral reefs, using the Great Barrier Reef as a test case with reef data going back to 1996, as well as information gathered during recent tropical cycles. The study found that tropical cyclones between 2009 and 2014  caused record destruction of corals. Continue reading “Coral bleaching threat persists in Southern Hemisphere”

January 2017 climate change hot spots include the Arctic, Australia and South America

January 2017 was ‘only” the third-warmest January on record according to NOAA, and the second-warmest, according to the EU Climate Change Centre.

Staff Report

Along with recording the third-highest global average January temperature, scientists with the World Meteorological Organization have been tracking the Polar equivalent of heatwaves, as strong Atlantic storms driving temperatures in the Arctic to near freezing, at times 50 degrees Fahrenheit above the seasonal average.

“Temperatures in the Arctic are quite remarkable and very alarming,” said World Climate Research Programme Director David Carlson. “The rate of change in the Arctic and resulting shifts in wider atmospheric circulation patterns, which affect weather in other parts of the world, are pushing climate science to its limits.” Continue reading “January 2017 climate change hot spots include the Arctic, Australia and South America”

It’s official — 2016 is the warmest year on record

Climate data show steady pace of global warming

Staff Report

For the third year in a row, the average global temperature climbed to a new record in 2016, reaching 1.69 degrees Fahrenheit above the 20th century average, according to the most recent state of the climate report from the National Oceanic and Atmospheric Administration.

During a conference announcing the new data, federal scientists said they can confidently  determine that Earth is now in its warmest era since about 125,000 years ago, during a break between ice ages, and there’s no sign that the warmup will stop anytime soon.

Staff Report

November’s average global temperature was 1.31 degrees Fahrenheit above the 20th century average, making it the fifth-warmest November on record. According to the latest global state of the climate report from the National Centers for Environmental Information, it was cooler than last year’s record by 0.41 degrees Fahrenheit, but 0.09 degrees warmer than the average for the 21st century.

According to the report, warmer-than-average conditions prevailed across most of the globe’s land areas, with record warmth in parts of central and southeastern Canada, where temperatures were at least 9 degrees Fahrenheit above the 1981–2010 average in many places. Other warm regions included the far northern tier of the United States along with a portion of the southwest, parts of western and southern Mexico, sections of eastern and west central Africa, and regions of some southeastern Asia island nations.

Staff Report

Satellite data about whale movements and ocean conditions have helped scientists create monthly whale hotspot maps that could help avert collisions between ships and marine mammals.

Developed by researchers with NOAA Fisheries, Oregon State University and the University of Maryland, the WhaleWhatch program alerts ships where there may be an increased risk of encountering these endangered whales.  NASA helped fund the project, which draws on ocean observations from NASA and NOAA satellites.

Climate: U.S. was record warm in June 2016

Deadly heatwaves and flooding part of emerging pattern of extremes

Utah and Arizona reported a record-warm June average temperature, with most other states also coming in above average.

Staff Report

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.

Climate: More global heat records tumble

Warm, warmer … warmest

February 2016 topped a string of preceding warm months with record-shattering global temperatures.

Staff Report

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.
