‘Global Warming Drought’ Over As Northern California Sets Wettest Year On Record

‘Global Warming Drought’ Over As Northern California Sets Wettest Year On Record

It is now the wettest year on record in the Northern California mountains, National Weather Service officials said Thursday.

An index of precipitation at eight sensors showed that just under 90 inches of rain and snow have fallen this winter in the northern Sierra Nevada.

The previous record of 88.5 inches was set in the winter of 1982-1983. The average for the region is 50 inches a year, according to the state Department of Water Resources.

The record was surpassed less than a week after Gov. Jerry Brown officially declared an end to California’s drought emergency — a largely symbolic pronouncement that left in place some water-conservation rules for the 40 million residents of the nation’s most populous state.

More snow and rain is likely to pad the record before the wet season ends.

A winter weather advisory was in effect for the northern Sierra for much of Thursday with forecasts for moderate to heavy snow along with rain at lower elevations. More storms were forecast for next week.

The measurements were taken from sensors spread from Mount Shasta near the Oregon border to Pacific House between Sacramento and South Lake Tahoe.

Winter storms have blanketed mountains in snow, flooded urban areas and caused damage that could top $1 billion.

The weather also taxed reservoirs, dams and levees designed to control floods and capture winter rain and snow for agriculture and drinking water throughout the state.

The five sensors that make up the San Joaquin region have recorded 68.2 inches of rain — almost double the average for this time of year and roughly on pace with the 1983 record of 77.4 inches, according to the Water Resources Department.

In 1982, HH Lamb wrote about how the ranges of birds and fishes had moved poleward in the first half of the 20thC.

When the Earth started cooling, this movement was reversed. All that animal and plant species are doing is returning to where they were a half a century or so ago.

There are many threats facing eco systems, but a barely noticeable increase in temperature is not one of them.

Easter Ice Hunt

Easter Ice Hunt

As the photo shows, back in February 2017 you didn’t have to go looking for ice, it came after you. A convoy including icebreakers was trapped by ice in Chukchi, reported in Siberian Times and posted here as Arctic Ice Takes Revenge.

Now we are two weeks into April and about a month into the Arctic melt season. The hunt is on to see how ice extent reacts to the sun, warmer water and weather.

Firstly the graph shows that both this year and last have dipped below 14M km2, 400k km2 below average but still ahead of 2007. Day 104 refers to April 14.

As noted before, the heart of the Arctic is still frozen solid, with changes in extent occurring mainly in the marginal seas that usually melt out by September. Comparing the last two weeks in the Atlantic side, we can see almost no change overall, with an unexpected small increase in Barents Sea.

On the Pacific side is where the deficit to average appears in the melting of both Bering and Okhotsk Seas.

The table compares 2017 regional extents to average and to 2007.

 (14) Sea_of_Okhotsk 417538 648579 -231042 576913 -159375

Clearly, Barents is down slightly to average but more than offset by surpluses in Baffin and Greenland. The 2017 differences from average and from 2007 arises from Bering and Okhotsk in the Pacific.

Summary

Despite what you may hear from alarmist sources, there is plenty of Arctic Ice if you know where to look for it.
