MASIE ice extents reported March 8 through 31, 2017.

This time of year the heart of the Arctic is frozen solid, and the only changes occur in the marginal seas.  Above shows the Atlantic basins, especially Kara, Barents, Greenland Sea and Baffin Bay.  All of them seesawed during the month, with some fall off at the end, especially noticeable in Baffin Bay.

Meanwhile on the Pacific side, Bering fluctuated, while Okhotsk lost extent steadily toward month end.

Context

The monthly ice extent average for March provides indication of any year’s annual maximum, prior to melting down to the September annual minimum. Sometimes a lower March extent yields a lower September extent, but not always: 2012 had both the highest maximum and lowest minimum in the last 11 years. That was the year of the Great Arctic Cyclone, and an outlier in the record.

Looking at the 11-year averages in the MASIE data set, the pattern in round numbers is:
Maximum: 15.0 M km2
Minimum: 4.8 M km2
Loss: 10.2 M km2
Loss: 68.0 % of maximum

Over this period, the ice extent loss most years varies from 66 to 70% of the maximum. Obviously, all the factors affecting ice extents are in play: (Water, Wind and Weather) with the September outcome uncertain, but likely to be in the range observed.

March 2017 in Comparison

As has been reported, ice formation this year has been sluggish compared to other years. The graph below shows March 2017 compared with the 11 year average, and with 2006 and 2016, as well as SII (Sea Ice Index).

This March started below average, held steady until the third week, recovered some before dropping off at the end.  SII showed lower extents all month but drew close at the end.  2006 dropped off more rapidly than 2017, while 2016 ended near average.

The Table below shows Day 90 extents across the Arctic Seas compared to averages and 2006, the lowest recent year.

The marginal seas in the Atlantic and Pacific make the 2017 deficits to average: especially Barents, Kara, Bering and Okhotsk. 2017 Surpluses in Greenland Sea and Baffin Bay are smaller, but make most of the difference with 2006.

2017 Outlook

March this year averaged 14.509 M Km2 compared to the 11 year average of 14.986 M km2, a deficit of 478k km2 or 3.2% down. That suggests that a typical melt later this year would result in a minimum of about 4.5 or 4.6 M km2, slightly down from the 11 year average of 4.8M km2.

Sea Ice Index (SII) typically shows less ice than MASIE, and SII reports a 2017 March average ice extent of 14.273 M km2 compared to SII 11 year March average of 14.842, a drop of 569k km2 or 3.8%.  Folks relying on SII may be expecting a lower September minimum, perhaps even breaking the present plateau of ice extents since 2007.  That remains to be seen.

Will EPA’s Scientific Integrity Office Censor EPA Chief?

Will EPA’s Scientific Integrity Office Censor EPA Chief?

via The Global Warming Policy Forum (GWPF)
http://www.thegwpf.com

The U.S. Environmental Protection Agency’s scientific integrity watchdog is reviewing whether EPA chief Scott Pruitt violated the agency’s policies when he said in a television interview he does not believe carbon dioxide is driving global climate change, according to an email seen by Reuters on Friday.

Lawyers for environmental group the Sierra Club had asked the EPA’s Office of Inspector General to check whether Pruitt violated policy when he told a CNBC interviewer on March 9, “I would not agree that it’s a primary contributor to the global warming that we see.”

The EPA Inspector General’s office responded to the Sierra Club on Thursday in an email, saying it had referred the matter to the EPA’s Scientific Integrity Officer, Francesca Grifo, for review.

“If after the SIO review, she concludes there is some aspect of the letter itself, or her findings or conclusions that she believes are appropriate for further consideration by the OIG, she will so notify the OIG,” the email stated.

A spokeswoman for the EPA defended Pruitt’s comments.

“Administrator Pruitt makes no apologies for having a candid dialogue about climate science and commonsense regulations that will protect our environment, without creating unnecessary regulatory burdens that kill jobs,” said Liz Bowman in an emailed statement.

“Differing views and opinions on scientific and technical matters is a legitimate and necessary part of EPA’s decision-making process, which is consistent with EPA’s scientific integrity policy that was in place even during the Obama administration,” she added.

The EPA website says its scientific integrity policy requires EPA officials and staff to ensure the agency’s work respects the findings of the broader scientific community.

Remembering the Incredible New England Snowstorms of March 1956

Remembering the Incredible New England Snowstorms of March 1956

via Watts Up With That?
http://ift.tt/1Viafi3

When I wrote my recent post The 300th Anniversary of the Great Colonial Snowcover of 1717, I didn’t realize that one of the rivals to March 1717 was relatively recent.

March 1956 started with an unremarkable snow cover at the Blue Hill Weather Observatory a little south of Boston, Massachusetts.  However, snow storms in the second half of the month brought the month’s snowfall to an impressive 49.4″ (125.5 cm).

The following is a summary from Charles Orloff of Blue Hill on a paper by Conrad P. Mooka and Kenneth S. Norquest.

Remembering the Incredible Snowstorms
of March 1956

The recent snowstorm this March brings back memories of the big snows of March 1956. In New England winter can still rule in March and heavy snows can indeed occur. Even April can see heavy snowfalls – a future SkyMail will talk about that month.

March 1956 started with 6.4″ (16.3 cm) of snow on the ground at Blue Hill Observatory. By the end of the month, three 12 inch plus snowstorms had blanked the Northeast bringing the monthly total to 49.4″ (125.5 cm) making the winter of 1955-56 the third snowiest on the Observatory’s then 132 year record.

Of the three major snowfalls in March 1956 the storm from March 18-20th was the most significant with upwards of 20″ (51 cm) falling along the Northeast corridor and much of Southern New England. What was remarkable was that there were three snowstorms in March 1956 in a period of just 10 days. The storms started with a rather typical coastal development on March 14th which left 2.3″ (5.8) of snowfall at Blue Hill Observatory. The next storm was just two days later.

On Friday, March 16, 1956, by 1230 GMT the stage was set for the typical development of a coastal Low which often produces heavy snow and high winds in the Northeast. The North Atlantic States had been flooded with cold air due to eastward passage of a 1032-mb High from the Great Lakes region to Maine. Meanwhile, a wave, which developed in the West Gulf on the trailing polar front, had deepened and moved northeastward to eastern Kentucky. This was attended by widespread heavy rains in the Southeastern States and snow through the Ohio Valley eastward to southern New Jersey. By this time the typical pattern of development was evident. A warm front lay along the Carolina coast, then extended eastward north of Bermuda. An area of 3-hourly pressure falls of 4 to 5 mb, concentrated in eastern North Carolina and southeastern Virginia, strongly indicated a secondary development on the coast. By 0030 GMT, March 17, the low center in eastern Kentucky had entirely filled and the secondary Low had formed and deepened to 984 mb just off Atlantic City, N. J. The pressure at Atlantic City fell 25 mb in just 12 hours, indicating the explosive nature of the cyclogenesis which took place. Snow had now spread over all of the North Atlantic States, attended by strong winds with gales on the coast. By 0630 GMT, March 17, the center was 970 mb just east of Nantucket. Snow and strong winds covered the Northeastern States and gales continued on the New England coast. By 1230 GMT, March 17, the storm was well out to sea some 380 miles east of Boston. This storm was a nearly perfect example of the rapid development of a coastal storm. It deposited 14″ of new snow at Albany, N. Y., 6″ at Hartford, Conn., and 10″ at Concord, N. H., New York City and Boston (35, 15, and 25 cm). In just 12 hours the intense storm moved from a position off the coast near Atlantic City to 380 miles east of Boston. Snowfall at Blue Hill Observatory measured 12.9″ (32.8 cm).

19560319

All of this set the stage for the biggest storm which occurred from March 18-20th. By early morning of the 18th (1230 GMT) the area of snowfall attending the developing southern low centers over eastern Kentucky and southern West Virginia had enlarged to cover the Ohio Valley and had spread eastward over the Appalachians to cover most of the mid-Atlantic states. Precipitation fell as rain over southern Maryland and southern Virginia, while snow was falling over the remainder. Snow had spread from southern New Jersey, beginning at 1545 GMT at Newark and 1603 GMT at New York City. At this time one low center was moving eastward near Quantico, Va., while another was also moving eastward near Danville, Va. During the next 6 hours there was little change in the area of precipitation. Showers and thunderstorms moved eastward across southern Virginia and eastern North Carolina as the southern low center moved to the coast near Elizabeth City, N. C. and began to strengthen into a dangerous gale. Snow continued from Maryland and Delaware northward over Pennsylvania and into Long Island as well as westward to Cincinnati, Ohio, as the northern Low center moved to southern Delaware. By 0630 GMT on the 19th the surface Low system was off the coast, some distance southeast of New Jersey, moving northeastward. Snowfall continued over the New York City area, New Jersey, Delaware, Maryland, and eastern Pennsylvania. On the 19th the snow spread over Southern New England. Meanwhile, the low pressure cyclonic center moved northeastward along the coast at an ever-slowing rate toward Nantucket, finally passing to the northeast of that point and filling on the 20th, while a new center formed farther east near Sable Island. It is interesting to note that the duration of precipitation in the form of snow at Philadelphia, Trenton, Atlantic City, Newark, and New York City (Battery) ranged from 31 hours at Philadelphia to 35 hours at Atlantic City. Farther east, over Southern New England, the duration ranged from 26 hours at New Haven to 24 hours at Boston. In spite of this, the depth of new snow added by the storm was remarkably uniform, measuring 12 to 13″ (~32 cm) at Trenton, New York City, New Haven, Bradley Field (Hartford), and Boston. A notable exception was the 18″ (46 cm) which fell at Newark. Snowfall at Blue Hill was 17.5″ (44.0 cm) with a total snowfall on the ground on the 20th of 25.3″ (64.3 cm).

All in all, this was one of the most severe and deadly snowstorms in Southern New England history. Approximately 162 people were killed and most towns were left paralyzed under deep snow drifts as high as 14 feet (4+ meters).

As if this wasn’t enough the blizzard of March 18-20 was followed by another 12.3″ (31.2 cm) snowfall on March 24th with a final 3″ (7.6 cm) falling from the 29th to the 30th. Many of us remember shoveling much of the month, fortunately under a warm March sun!


The Blue Hill Observatory was built atop a hill a little south of Boston in 1885. It was the first weather observatory built in the United States and has an unbroken weather record.

Some of their early “high tech” equipment is still in use although “antique” is sometimes the better description now. If you’re in the area, check their schedule and stop in for a visit. Whether there or not, check out their store, especially their books, or donate some money to help make up for cuts in state support.

April Fools!

April Fools!

via NOT A LOT OF PEOPLE KNOW THAT
http://ift.tt/16C5B6P

By Paul Homewood

 

h/t Joe Public

 

Well, they were not published on April 1st. but they might just as well have been.

Just some of the ludicrous, eco-scares from down the years.

For instance, here are 18 examples of the spectacularly wrong predictions made around 1970 when the “green holy day” (aka Earth Day) started:

 

1. Harvard biologist George Wald estimated that “civilization will end within 15 or 30 years unless immediate action is taken against problems facing mankind.”

2. “We are in an environmental crisis which threatens the survival of this nation, and of the world as a suitable place of human habitation,” wrote Washington University biologist Barry Commoner in the Earth Day issue of the scholarly journal Environment.

3. The day after the first Earth Day, the New York Times editorial page warned, “Man must stop pollution and conserve his resources, not merely to enhance existence but to save the race from intolerable deterioration and possible extinction.”

4. “Population will inevitably and completely outstrip whatever small increases in food supplies we make,” Paul Ehrlich confidently declared in the April 1970 Mademoiselle. “The death rate will increase until at least 100-200 million people per year will be starving to death during the next ten years.”

5. “Most of the people who are going to die in the greatest cataclysm in the history of man have already been born,” wrote Paul Ehrlich in a 1969 essay titled “Eco-Catastrophe! “By…[1975] some experts feel that food shortages will have escalated the present level of world hunger and starvation into famines of unbelievable proportions. Other experts, more optimistic, think the ultimate food-population collision will not occur until the decade of the 1980s.”

6. Ehrlich sketched out his most alarmist scenario for the 1970 Earth Day issue of The Progressive, assuring readers that between 1980 and 1989, some 4 billion people, including 65 million Americans, would perish in the “Great Die-Off.”

7. “It is already too late to avoid mass starvation,” declared Denis Hayes, the chief organizer for Earth Day, in the Spring 1970 issue of The Living Wilderness.

8. Peter Gunter, a North Texas State University professor, wrote in 1970, “Demographers agree almost unanimously on the following grim timetable: by 1975 widespread famines will begin in India; these will spread by 1990 to include all of India, Pakistan, China and the Near East, Africa. By the year 2000, or conceivably sooner, South and Central America will exist under famine conditions….By the year 2000, thirty years from now, the entire world, with the exception of Western Europe, North America, and Australia, will be in famine.”

9. In January 1970, Life reported, “Scientists have solid experimental and theoretical evidence to support…the following predictions: In a decade, urban dwellers will have to wear gas masks to survive air pollution…by 1985 air pollution will have reduced the amount of sunlight reaching earth by one half….”

10. Ecologist Kenneth Watt told Time that, “At the present rate of nitrogen buildup, it’s only a matter of time before light will be filtered out of the atmosphere and none of our land will be usable.”

11. Barry Commoner predicted that decaying organic pollutants would use up all of the oxygen in America’s rivers, causing freshwater fish to suffocate.

12. Paul Ehrlich chimed in, predicting in his 1970 that “air pollution…is certainly going to take hundreds of thousands of lives in the next few years alone.” Ehrlich sketched a scenario in which 200,000 Americans would die in 1973 during “smog disasters” in New York and Los Angeles.

13. Paul Ehrlich warned in the May 1970 issue of Audubon that DDT and other chlorinated hydrocarbons “may have substantially reduced the life expectancy of people born since 1945.” Ehrlich warned that Americans born since 1946…now had a life expectancy of only 49 years, and he predicted that if current patterns continued this expectancy would reach 42 years by 1980, when it might level out.

14. Ecologist Kenneth Watt declared, “By the year 2000, if present trends continue, we will be using up crude oil at such a rate…that there won’t be any more crude oil. You’ll drive up to the pump and say, `Fill ‘er up, buddy,’ and he’ll say, `I am very sorry, there isn’t any.’”

15. Harrison Brown, a scientist at the National Academy of Sciences, published a chart in Scientific American that looked at metal reserves and estimated the humanity would totally run out of copper shortly after 2000. Lead, zinc, tin, gold, and silver would be gone before 1990.

16. Sen. Gaylord Nelson wrote in Look that, “Dr. S. Dillon Ripley, secretary of the Smithsonian Institute, believes that in 25 years, somewhere between 75 and 80 percent of all the species of living animals will be extinct.”

17. In 1975, Paul Ehrlich predicted that “since more than nine-tenths of the original tropical rainforests will be removed in most areas within the next 30 years or so, it is expected that half of the organisms in these areas will vanish with it.”

18. Kenneth Watt warned about a pending Ice Age in a speech. “The world has been chilling sharply for about twenty years,” he declared. “If present trends continue, the world will be about four degrees colder for the global mean temperature in 1990, but eleven degrees colder in the year 2000. This is about twice what it would take to put us into an ice age.”

Then in 2004, the Pentagon was warning that climate change will destroy us, as the Guardian reported:

Climate change over the next 20 years could result in a global catastrophe costing millions of lives in wars and natural disasters..

A secret report, suppressed by US defence chiefs and obtained by The Observer, warns that major European cities will be sunk beneath rising seas as Britain is plunged into a ‘Siberian’ climate by 2020. Nuclear conflict, mega-droughts, famine and widespread rioting will erupt across the world.

The document predicts that abrupt climate change could bring the planet to the edge of anarchy as countries develop a nuclear threat to defend and secure dwindling food, water and energy supplies. The threat to global stability vastly eclipses that of terrorism, say the few experts privy to its contents.

‘Disruption and conflict will be endemic features of life,’ concludes the Pentagon analysis. ‘Once again, warfare would define human life.’

The findings will prove humiliating to the Bush administration, which has repeatedly denied that climate change even exists. Experts said that they will also make unsettling reading for a President who has insisted national defence is a priority.

The report was commissioned by influential Pentagon defence adviser Andrew Marshall, who has held considerable sway on US military thinking over the past three decades. He was the man behind a sweeping recent review aimed at transforming the American military under Defence Secretary Donald Rumsfeld.

Climate change ‘should be elevated beyond a scientific debate to a US national security concern’, say the authors, Peter Schwartz, CIA consultant and former head of planning at Royal Dutch/Shell Group, and Doug Randall of the California-based Global Business Network.

 

An imminent scenario of catastrophic climate change is ‘plausible and would challenge United States national security in ways that should be considered immediately’, they conclude. As early as next year widespread flooding by a rise in sea levels will create major upheaval for millions.

Sir John Houghton, former chief executive of the Meteorological Office – and the first senior figure to liken the threat of climate change to that of terrorism – said: ‘If the Pentagon is sending out that sort of message, then this is an important document indeed.’

Bob Watson, chief scientist for the World Bank and former chair of the Intergovernmental Panel on Climate Change, added that the Pentagon’s dire warnings could no longer be ignored.

‘Can Bush ignore the Pentagon? It’s going be hard to blow off this sort of document. Its hugely embarrassing. After all, Bush’s single highest priority is national defence. The Pentagon is no wacko, liberal group, generally speaking it is conservative. If climate change is a threat to national security and the economy, then he has to act. There are two groups the Bush Administration tend to listen to, the oil lobby and the Pentagon,’ added Watson.

‘You’ve got a President who says global warming is a hoax, and across the Potomac river you’ve got a Pentagon preparing for climate wars. It’s pretty scary when Bush starts to ignore his own government on this issue,’ said Rob Gueterbock of Greenpeace.

The following year, the Guardian was also warning us that there would be 50m environmental refugees by end of decade:

Rising sea levels, desertification and shrinking freshwater supplies will create up to 50 million environmental refugees by the end of the decade, experts warn today. Janos Bogardi, director of the Institute for Environment and Human Security at the United Nations University in Bonn, said creeping environmental deterioration already displaced up to 10 million people a year, and the situation would get worse.

"There are well-founded fears that the number of people fleeing untenable environmental conditions may grow exponentially as the world experiences the effects of climate change," Dr Bogardi said. "This new category of refugee needs to find a place in international agreements. We need to better anticipate support requirements, similar to those of people fleeing other unviable situations."

With predictions like that, even Peter Wadhams looks slightly sane!
