What part of the word ‘change’ are you having trouble with?

Climate change denialists and cloud cuckoo land!

Yesterday, I republished the recent Post from Martin Lack under my title of Playing with fire!  In that Post there was a reference to just one example of the very different climatic world that we all live in.  That reference was to the recent huge devastation of the apple and soft-fruit crops in Northern USA and Canada.

The website Climate Denial Crock of the Week carried the story in a clear and fine fashion.  Let me borrow some of that content,

Canada/US Great Lakes Area Fruit Growers “Wipeout” Due to Extreme Spring. Deniers: “They Need More CO2″

May 18, 2012

The brown centre of an apple blossom indicates a bloom that would not result in an apple being produced following this spring’s unusual weather.

Elsewhere on the blog, we are still hearing that “CO2 is good for Plants”. Meanwhile, here in the reality based community….

Windsor Star, May 5: 

A catastrophic freeze has wiped out about 80 per cent of Ontario’s apple crop and has the fruit industry looking at losses already estimated at more than $100 million.

“This is the worst disaster fruit growers have ever, ever experienced,” Harrow-area orchard owner Keith Wright said Friday. “We’ve been here for generations and I’ve never heard of this happening before.

“This is unheard of … all fruit growing areas in the Great Lakes area, in Michigan, Pennsylvania, New York State, Ontario, are all basically wiped out.”

Wright lost hundreds of thousands of dollars worth of apples and peaches Sunday morning when freezing temperatures killed the blossoms.

Warm temperatures caused fruit trees to bloom early and when temperatures plummeted Sunday morning it damaged or wiped out much of the $60-million apple crop and 20 to 30 per cent of Ontario’s $48-million tender fruit crop which includes peaches, cherries, pears, plums and nectarines.

Brian Gilroy, a Georgian Bay-area apple grower who is chairman of the Ontario Apple Growers, said the loss to fruit growers and the economy will easily be more than $100 million. On top of the lost yield or no crop at all, orchard workers and spinoff industries such as juice, packing, storage and farm supplies will be affected.

Gilroy said consumers will find locally grown apples pricey and difficult to find this fall. Some varieties of apples, such as Empire, will be very difficult to find.

Washington State has a good crop but consumers should expect apple prices to jump because all of northeastern North America was affected, he said.

The article goes on to report from the Globe and Mail and the Toronto Star.  It does not make for pretty reading!

Then in a private email, Martin referred me to this Think Progress article of May 19th,

April 2012: Earth’s 5th Warmest On Record And La Niña Officially Ends, So The Heat Is On.

By Climate Guest Blogger on May 19, 2012 at 3:09 pm

JR: It’s remarkable how warm it was globally in April considering that we were only just coming out of a double dip La Niña. If we don’t triple dip, we’ll set more temperature records soon. Indeed, NOAA models predict a good chance of an El Niño forming in the late summer, which would make it quite likely next year would be the hottest on record. As for April, you’ll note it was hot in the ‘wrong’ places again — over much of the tundra, which is a carbon time bomb

The Think Progress article then draws heavily on an extensive comment from Dr.Jeff Master’s WunderBlog that I am going republish, hopefully in the interests of helping to spread the truth about this planet of ours.

April 2012 was the globe’s 5th warmest April on record, according to the National Oceanic and Atmospheric Administration’s National Climatic Data Center (NCDC). NASA rated April 2012 as the 4th warmest April on record. April 2012 global land temperatures were the 2nd warmest on record, and the Northern Hemisphere land surface temperature was 1.74°C (3.13°F) above the 20th century average, marking the warmest April since records began in 1880. Global ocean temperatures were the 11th warmest on record, and April 2012 was the 427th consecutive month with ocean temperatures warmer than the 20th century average. The last time the ocean temperatures were below average was September 1976. The increase in global temperatures relative to average compared to March 2012 (16th warmest March on record) was due, in part, to warming waters in the Eastern Pacific, due to the La Niña event that ended in April. Global satellite-measured temperatures for the lowest 8 km of the atmosphere were 6th or 4th warmest in the 34-year record, according to Remote Sensing Systems and the University of Alabama Huntsville (UAH). April temperatures in the stratosphere were the 1st to 4th coldest on record. We expect cold temperatures there due to the greenhouse effect and to destruction of ozone due to CFC pollution. Northern Hemisphere snow cover during April was 4th smallest in the 46-year record. Wunderground’s weather historian, Christopher C. Burt, has a comprehensive post on the notable weather events of April in his April 2012 Global Weather Extremes Summary. Notably, national heat records (for warmest April temperature on record) occurred in the United States (a tie), Germany, Austria, Poland, Belarus, Lithuania, Moldova, Hungry, Croatia, Ukraine, and Slovakia as well as the cities of Moscow and Munich.

La Niña officially ends

According to NOAA’s Climate Prediction Center (CPC), La Niña conditions are no longer present in the equatorial Pacific, where sea surface temperatures were approximately average as of May 13. The threshold for a La Niña is for these temperatures to be 0.5°C below average or cooler. CPC forecasts that neutral conditions will persist though the summer, with a 41% chance of an El Niño event developing in time for the August – September – October peak of hurricane season. El Niño conditions tend to decrease Atlantic hurricane activity, by increasing wind shear over the tropical Atlantic.

April Arctic sea ice extent near average
Arctic sea ice extent was near average in April 2012, the 17th lowest (18th greatest) extent in the 35-year satellite record, according to the National Snow and Ice Data Center (NSIDC). This was the largest April Arctic sea ice extent since 2001. However, ice in the Arctic is increasingly young, thin ice, which will make it easy for this year’s ice to melt away to near-record low levels this summer, if warmer than average weather occurs in the Arctic.

So to those that still think the jury is out on climate change, let me just repeat the title, “What part of the word change are you having trouble with?”

Last word, for now!

Last mutterings for now regarding man’s effect on our Planet!

There’s been a string of items on Learning from Dogs in recent days about mankind’s footprint changing our planet but this Blog is not a single issue Blog unless learning the values of life from dogs is to be seen as a single issue.

So I’m going to include a few more items about climate change/global warming here and leave it for a while.  (But, please, don’t let that stop you sending me interesting stuff, as so many of you lovely readers do!)

So more evidence about how the planet has warmed up in this video released by NASA.

Global temperatures have warmed significantly since 1880, the beginning of what scientists call the “modern record.” At this time, the coverage provided by weather stations allowed for essentially global temperature data. As greenhouse gas emissions from energy production, industry and vehicles have increased, temperatures have climbed, most notably since the late 1970s. In this animation of temperature data from 1880-2011, reds indicate temperatures higher than the average during a baseline period of 1951-1980, while blues indicate lower temperatures than the baseline average.

NASA Finds 2011 Ninth-Warmest Year on Record

19th January, 2012

The global average surface temperature in 2011 was the ninth warmest since 1880, according to NASA scientists. The finding continues a trend in which nine of the 10 warmest years in the modern meteorological record have occurred since the year 2000.

NASA’s Goddard Institute for Space Studies (GISS) in New York, which monitors global surface temperatures on an ongoing basis, released an updated analysis that shows temperatures around the globe in 2011 compared to the average global temperature from the mid-20th century. The comparison shows how Earth continues to experience warmer temperatures than several decades ago. The average temperature around the globe in 2011 was 0.92 degrees F (0.51 C) warmer than the mid-20th century baseline.

“We know the planet is absorbing more energy than it is emitting,” said GISS Director James E. Hansen. “So we are continuing to see a trend toward higher temperatures. Even with the cooling effects of a strong La Niña influence and low solar activity for the past several years, 2011 was one of the 10 warmest years on record.”

The difference between 2011 and the warmest year in the GISS record (2010) is 0.22 degrees F (0.12 C). This underscores the emphasis scientists put on the long-term trend of global temperature rise. Because of the large natural variability of climate, scientists do not expect temperatures to rise consistently year after year. However, they do expect a continuing temperature rise over decades.

The first 11 years of the 21st century experienced notably higher temperatures compared to the middle and late 20th century, Hansen said. The only year from the 20th century in the top 10 warmest years on record is 1998.

Higher temperatures today are largely sustained by increased atmospheric concentrations of greenhouse gases, especially carbon dioxide. These gases absorb infrared radiation emitted by Earth and release that energy into the atmosphere rather than allowing it to escape to space. As their atmospheric concentration has increased, the amount of energy “trapped” by these gases has led to higher temperatures.

Global temperature difference

The carbon dioxide level in the atmosphere was about 285 parts per million in 1880, when the GISS global temperature record begins. By 1960, the average concentration had risen to about 315 parts per million. Today it exceeds 390 parts per million and continues to rise at an accelerating pace.

The temperature analysis produced at GISS is compiled from weather data from more than 1,000 meteorological stations around the world, satellite observations of sea surface temperature and Antarctic research station measurements. A publicly available computer program is used to calculate the difference between surface temperature in a given month and the average temperature for the same place during 1951 to 1980. This three-decade period functions as a baseline for the analysis.

The resulting temperature record is very close to analyses by the Met Office Hadley Centre in the United Kingdom and the National Oceanic and Atmospheric Administration’s National Climatic Data Center in Asheville, N.C.

Hansen said he expects record-breaking global average temperature in the next two to three years because solar activity is on the upswing and the next El Niño will increase tropical Pacific temperatures. The warmest years on record were 2005 and 2010, in a virtual tie.

“It’s always dangerous to make predictions about El Niño, but it’s safe to say we’ll see one in the next three years,” Hansen said. “It won’t take a very strong El Niño to push temperatures above 2010.”

Finally, the blogsite Skeptical Science have recently published a fascinating graphic that shows how a single set of data can be interpreted in different ways.  That graphic may be seen by clicking here and it comes from a revealing article Still Going Down the Up Escalator.  Go read it!
