These items caught my eye – 12 April 2013

Each week, I’ll pull together a range of items that have attracted my attention. I hope you will find the variety of topics covered both interesting and enlightening.

The Sun Was in My Eyes – Was It More Likely Over the Past 3-Plus Decades?

Alternate Title: On Pinker et al 2005 and the Positive Trend in the NCEP-DOE Reanalysis-2 Surface Downward Solar Radiation Flux

Over at Tallbloke’s Talkshop, Tallbloke has a post about the Pinker et al 2005 paper “Do Satellites Detect Trends in Surface Solar Radiation?” I’ve included (cross posted) that post in this one. Second, a positive trend also appears in the NCEP-DOE Reanalysis-2 Surface Downward Solar Radiation Flux data that’s available through the NOAA NOMADS website, though the positive trend is not as significant. Not too surprising, the multi-model ensemble mean of the climate models prepared for the IPCC’s upcoming 5th Assessment Report (AR5) do not show an increase in downward solar radiation at the surface. Another model failure to add to the ever-growing list?

First, Tallbloke’s post: Keep in mind, the satellite-based surface solar radiation flux “data” presented in Pinker et al is not based on direct measurements. It is calculated primarily from ISCCP cloud amount data. [I’ve added figure numbers to the following illustrations for my post.]:


Errrmm, why I have not heard of this 2006 [sic] paper before? 1.6W/m^2 per decade is a not insignificant trend. Did the IPCC ignore this?

English Winters Back To Normal–Julia Blames Global Warming!

According to the Sun, Britain’s winters are getting colder because of melting Arctic ice, the Government’s forecaster said yesterday.

Met Office chief scientist Julia Slingo said climate change was “loading the dice” towards freezing, drier weather — and called publicly for the first time for an urgent investigation.

Prof Slingo said: “If you look at the way our weather patterns have behaved over the past four or five years, we’re beginning to think that there is something happening.

“Our climate is being disrupted by the warming of the Arctic that we have observed very dramatically since 2007.

“We should pull together the best scientists to see how we can detect the influence of the Arctic on the jet stream, and on weather around the world.”

So just how cold have Britain’s winters become? Well, according to the Central England Temperature series, not very! The winter just gone ranks an unremarkable 187th coldest in the 354 years since the index started in 1660. Figure 1 shows just how unremarkable it has been. The 2012/13 winter finished at 3.83C, a fraction above the mean over the whole record of 3.72C.

Climate Models Got The NAO All Wrong – Climate Science Now Plagued By Contradictory Explanations

Northern hemisphere winters in the big picture
by Juraj Vanovcan (Slovakia)

According to the climate models, anthropogenic warming is supposed to predominantly manifest itself by increasing the winter temperatures th the middle latitudes – caused by the increased “greenhouse effect“ or increased amount of long wave infrared radiation LWIR from the sky to the surface. Children won’t know what the snow is, was the meme in 2000s after a string of warm winters in Europe.

Central England temperature vs Arctic oscillation index.

Central England temperature vs Arctic oscillation index.

Only a decade later, things changed and cold and snowy winters are now becoming the norm and not the exception over all of Europe. Now the warming is the cause of invasions of cold Arctic air into mid-latitudes, some climatologists insist. They are basically admitting that not LWIR, but prevailing direction of air circulation makes a winter season warmer or colder than average. Of course there is another popular ad-hoc theory plugging the hole. It relates to the loss of summer ice to weather half a year later.

2012 US Drought Was Not Caused By Climate Change

April 12 2013 by Tory Aardvark

The summer of 2012 was one of the hottest on record, America’s corn belt was parched dry, frequent comparisons were to made to the Dust Bowl disasters of the 1930s, but unlike the 1930s this modern drought was hailed as further proof of the hand of man influencing the climate.

The Boy King Obama, facing re-election in November 2012 immediately attributed the drought to Anthropogenic Global Warming, the usual Green suspects rallied around the king, who then received even more support for his theory from such Hollywood scientific luminaries as Bette Midler, the guy with the squeaky voice, what’s his name, oh yeah Matt Damon and Barbra Streisand to name the most irritating but a few.

2012 US Drought Was Not Caused By Climate Change

The summer of 2012 was one of the worst droughts in US history, Barack Obama and other prominent Greens said the drought was caused by Global Warming.

So the stage is set, the good and the Green have written the script, another weather event caused by CO2 and man, further proof of man made climate change, but was the 2012 US drought really caused by Anthropogenic Climate Change?
