Ted: Ideas worth shredding?

I recently discovered that James Hansen is major influencer behind this incredibly one-sided climate change primer on TED masquerading as a balanced introduction:

http://www.ted.com/read/ted-studies/environmental-studies/introductory-essay.

One quote:

It’s also not surprising that the scientific evidence is contested, given that the indicators of climate change — like changing precipitation patterns over decadal time scales — may be difficult for ordinary citizens to detect, and given what’s at stake once we acknowledge that those indicators are correct. Initially — and even today, despite the fact that we’ve reached the gold standard for scientific certainty — some have questioned the quantity and quality of the evidence, feeding the public’s perception that the science is half-baked. In reality, by the time Hansen delivered his congressional testimony in 1988, he’d been researching the relationship between atmospheric components and temperature since the 1960s, building upon a line of scientific inquiry stretching back at least a century.

Note the references I have highlighted in bold. The first suggests that we are too stupid to have an opinion and the second is a meaningless qualification that has no place in real science and again just says, stop thinking we know better. Of course, no discussion of models not matching observations and minor details like that.

Ted should hang his head in shame.

Polar bear habitat – more Arctic sea ice in Canada this week than in early 1970s

I am going to categorise this good news under “climate change” and “inspiring”!

polarbearscience

This week, Arctic sea ice in Canada, where 2/3 of the world’s polar bears live, had more sea ice than was present in the early 1970s. Globally, the ice is spitting-distance close to the 1981-2010 average calculated by the NSIDC for this date – which means lots of winter/spring hunting habitat for polar bears.

This is the peak of the polar bear birthing season (both in the wild and in zoos.) Newborns will be snug in maternity dens built by their mothers onshore or on the sea ice; the rest of the population will be out on the ice.

Regional ice charts going back to the late 1960s and early 1970s for this week show even more surprises — have a look.

Ed Hoskins: The diminishing influence of increasing Carbon Dioxide CO2 on temperature

Tallbloke's Talkshop

Here’s another guest post from Ed Hoskins. This one deals with the IPCC’s own figures fro the effect of CO2 on global tamperature, demonstrating that due to the logarithmic limitation as this trace gas increases, future warming will be limited to within beneficial limits.

The diminishing influence of increasing Carbon Dioxide CO2 on temperature
Ed Hoskins MAarch (Cantab)  BDS (Lond).

The temperature increasing capacity of atmospheric CO2 is theoretically plausible, but its influence is known and widely accepted to diminish as its concentration increases. It diminishes logarithmically with increasing concentration.

Global Warming advocates and Climate Change sceptics both agree on this. IPCC Published reports, (TAR), acknowledge that the effective temperature increase caused by growing concentrations of CO2 in the atmosphere radically diminishes with increasing concentrations. This information has been presented in the IPCC reports. It is well disguised for any lay reader, (Chapter 6. Radiative Forcing of Climate Change: section 6.3.4 Total…

New Study: Two Thousand Years of Northern European Summer Temperatures Show a Downward Trend

Watts Up With That?

In a paper published in the Journal of Quaternary Science, Esper et al. (2014) write that tree-ring chronologies of maximum latewood density (MXD) “are most suitable to reconstruct annually resolved summer temperature variations of the late Holocene.” And working with what they call “the world’s two longest MXD-based climate reconstructions” – those of Melvin et al. (2013) and Esper et al. (2012) – they combined portions of each to produce a new-and-improved summer temperature history for northern Europe that stretches all the way “from 17 BC to the present.” And what did they thereby learn?

As the international team of researchers from the Czech Republic, Finland, Germany, Greece, Sweden and Switzerland describes it, this history depicts “a long-term cooling trend of -0.30°C per 1,000 years over the Common Era in northern Europe” (see figure below). Most important of all, however, they note that their temperature reconstruction…
