climate change

2012 01 27 003Overall, for us, this winter has been crazily mild.  While, we did have one spell in December that was cold enough to brown much of the ground vegetation that normally stays green in this part of the country, it has been much warmer than normal for most of the season.

Still, it’s not normal to have daffodils in January, but we have the first blossom of the year – and the forecast is for temperatures above 60°F (15.5°C) for the week ahead.

So is winter over?  Where is all the cold weather? Is this global warming?

2011 02 10 b 027Winter’s probably not over here.  Typically, our snowiest month is February, followed by March, and we’ve even had snow in April, though some years we don’t get any snow at all. Last year, on February 9th, we had nearly a foot, and that was the second snow of the week.

On the other hand, spring-like conditions in early February 2008 led to a tornado outbreak that killed 13 in Arkansas (55 in southern US) with widespread damage and power outages.  I wouldn’t be surprised to see more big storms or winter weather in the next month, this year.

While it’s been unusually warm here,the reverse is true in other places.  Alaska has seen some brutally cold weather, worse than normal, and very heavy snow in places.  Sea ice in the Bering Sea is moving south much earlier than normal – and it’s moving fast, threatening to halt the snow-crap harvesting at the peak of the season.  Very cold temperatures and strong winds are pushing the ice south at 10 to 15 miles a day, 5 times the normal rate, threatening $8 million worth of crap pots and other gear already in the water.

In my view, our warmer weather and the colder weather in Alaska are just regional climate variations, not global warming or cooling, not a direct manifestation of climate change, though change is coming – it always is.

Globally,  temperatures have been relatively stable over the last decade.

While warming alarmists tout the decade as the warmest on record, “relatively stable” for more than 10 years isn’t warming.

As I’ve said in previous posts, my view is that we are on the verge of a significant drop in global temperature.  When it starts, if it starts, is anyone’s guess.  The loss of heat may have already begun in the waters of the world, without yet being felt in the weather.

One ominous prediction, though, says that the coming cold may move the geographical center of the corn producing region of North America from Iowa south into Kansas.

I’d rather have global warming.

What has the weather been like recently for you?

I’m running another test of the settings of the plugin to send posts to facebook.

UAH_LT_1979_thru_December_2011The figure provided with this test is a trend of satellite determined temperature variation for the lower atmosphere of the entire planet.  The figure is published monthly.  The temperature variation (or anomaly) is plotted as a temperature departure from the average value from January 1981 to December 2010.

The high peaks of the running 13 month average at 1998 and 2009 occurred from periods with strong El Ninos.  The drop at the end of the figure corresponds to La Nina periods

Cooling?

December 18, 2011

Cooling 3.5 degrees Celsius by 2020.

A new Norwegian study predicts that the annual mean temperature in Svalbard will drop 3.5°C over the period of 2009 to 2020 and mean winter temperature will drop 6°C.  The study is based on solar activity and the duration of solar cycles.  While the study is specific to Norway, if this actually occurs, temperatures will also drop significantly in other areas.

Cooling ‘til 2068?

A recent Chinese study of Tibetan tree rings indicates that there is nothing abnormal about the current climate conditions. The research team determined that several different natural cycles – 2-3 years, 100 years, 199 years, 800 years, and 1,324 years – combined to produce the climate history seen in the varying tree ring properties from the Tibetan Plateau.

The study indicate that temperatures have peaked and predicts that they will drop until 2068 AD, rising again after that.

The studies are two of a number of studies that run counter to the anthropogenic global warming theory so prominent in today’s media.

Global warming or global cooling?

If I had a choice, I’d prefer warming.

(I’d also prefer that governments not waste money in futile efforts that aren’t going to make a significant difference.  If we’re going to spend money like that, let’s do something worthwhile – like eradicating malaria or making sure more people in the world have clean water, something that would make a real difference instead of lining the pockets of bureaucrats or eco-snobs.)

Headline--Next solar cycle may be weakest for centuries

In the last couple of days, hundreds of news articles have been reporting on the strange behavior of the sun.

Three new scientific papers released simultaneously June 14th suggest that our sun’s magnetic activity and sunspot cycle may be going somewhat dormant for a while – possibly several decades – resulting in a period of global cooling. The results were announced at the annual meeting of the Solar Physics Division of the American Astronomical Society, which is being held this week at New Mexico State University in Las Cruces.

imageThis month’s weather has been very cruel in parts of the United States. A long-standing record for the number of April tornados has been broken – with a great many lives lost – and with the current North American temperature conditions, more may be coming in the next few weeks.

Tornados occur every year in North America, usually in the spring, starting in the southern part of the central United States and moving northward as the season progresses.  However, tornados have occurred in every month of the year and in every state of the United States – though not unknown in other parts of the world, by far the largest percentage of tornados occur in the USA, which averages about 1,200 tornados a year.

While there is a lot known about tornados and the conditions from which they tend to develop, there is still a lot unknown and, perhaps, some aspects that will forever be unknowable.

imageStrong winds, strong wind shear (significant differences in speed and direction of wind, varying with height), an unstable atmosphere and abundant low-level humidly are all contributors to the formation of tornadoes.  Wind shear, “the kind which develops when cold and warm air masses ‘collide’”1 is the key.

Active tornado seasons in the U.S. are almost always due to unusually COOL air persisting over the Midwest and Ohio Valley longer than it normally does as we transition into spring. 1

Lately, I’ve been watching and reading weather predictions from a new meteorological consulting firm, WeatherBell Analytics LLC, where Joe Bastardi, formerly of AccuWeather, said on April 2oth:

imageWhile the next 5 days sees another moderate outbreak of severe weather this weekend ( and the snow again on the northern side) its next week another lawyers, guns and money outbreak takes place. We are liable to see another 100 to 200 tornadoes before the month is out, making it the most active April ever. My reasoning for this is based on the major, and progressive, trough that swings into the plains early next week, and is leading a major crushing of the eastern ridge that will then take us into a May much like 2008 temp and precip wise.

It’s natural for people to want to find a reason when something bad happens and, all too often lately, the favorite culprit of anything bad in nature is climate change (aka global warming).  However, tornadoes are one feature of nature that is not predicted by global warming theory.  If anything, a warming globe would reduce the frequency of tornadoes.

It is well known that strong to violent tornado activity in the U.S. has decreased markedly since statistics began in the 1950s, which has also been a period of average warming. So, if anything, global warming causes FEWER tornado outbreaks…not more. In other words, more violent tornadoes would, if anything, be a sign of “global cooling”, not “global warming”.1

The ever improving weather knowledge of forecasters and meteorologists doubtlessly gave sufficient warning that saved many lives this month.

With every passing day, it seems, more precise digital tools emerge to clarify the inner heart of a storm cell in rampage. And yet, for all that solid information, the natural world can still seem murky, unpredictable and downright scary when it roars into full-throated chaos.

Tornadoes in particular, researchers say, straddle the line between the known and the profoundly unknowable.2

Solar activity continues to tend far lower than normal in a number of different parameters.
