Sea ice extent below average at both poles; northern hemisphere snow cover well above average
For the sixth month in a row, the global average temperature broke all historical records in October, soaring to 1.76 degrees Fahrenheit above the monthly average.
According the monthly climate report from NOAA’s National Climatic Data Center, it was by far the warmest October on record, breaking the record set just last year by 0.36 degrees Fahrenheit. It was also the largest the monthly departure from average from any month on record.
Both land- and sea-surface temperatures set records during the month, a sure sign that El Niño is fueling the spike in global temps and all but ensuring that this year will go down in the books as the warmest on record. Continue reading

Autumn tourism affected by road damage, but many attractions still open
A series of El Niño-fueled storms in October ravaged parts of Death Valley with floods and mudslides, leading to serious road damage and impacting other park resources, including Devils Hole, a spring that’s home to endangered fish.
According to the National Park Service, flash floods heavily damaged historic structures at Scottys Castle. In a press release, the park service floods pushed over a wall and buried some buildings with about five feet of mud.
The park often sees weather extremes, including flash flooding, but geologists said October’s events were near the edge of the historic envelope. Continue reading

More drought, more flooding …
An intensifying El Niño cycle could affect California weather.
The Pacific Ocean’s El Niño-La Niña cycle may become a dominant factor in West Coast weather by the end of this century and lead to more frequent weather extremes, according to a new study published in Nature Communications. Based on the findings, California could see the number of extreme droughts and floods by 2100, the researchers found.
A better understanding of what gives rise to El Nino and La Nina cycles — together known as El Nino-Southern Oscillation — might help California predict and prepare for more frequent droughts and floods in the coming century. Continue reading

Early October peak was lowest extent since 2008

This year’s El Niño may have been a factor limiting Antarctic sea ice, which peaked on October 6 at the lowest extent since 2008, according to an update from the National Snow and Ice Data Center.
The seasonal maximum extent rached about 7.27 million square miles, falling roughly in the middle of the record of Antarctic maximum extents compiled during the satellite record — in contrast to the past three years, which all set records. Continue reading

Up to 95 percent of U.S. coral reefs may be affected
Global warming is causing global coral bleaching, ocean scientists said today, confirming that rising ocean temperatures are resulting in massive and widespread impacts to reefs around the world.
“The coral bleaching and disease, brought on by climate change and coupled with events like the current El Niño, are the largest and most pervasive threats to coral reefs around the world,” NOAA’s Coral Reef Watch coordinator, Mark Eakin, said in a statement. Continue reading

Study tracks El Niño shifts
Climate change will likely subject many low-lying Pacific island nations to more extreme fluctuations in sea level from year to year, in synch with more intense El Niño cycles. Some years, high sea level will lead to bigger floods, while in other years, big drops in sea level will leave coral reefs exposed, according to researchers based in Hawaii and Australia.
