I came across a new paper trying to claim that increased temperatures caused by global warming will kill more “old people” in Beijing.
In the supplementary data they posted the graph of daily mortality.
First thing I noticed is that deaths peak in January and bottom out in the summer.
Yes there are some summertime spikes. But it appears that something like 60 more people die per day die in January than in July.
It seems to me that if winters are warmer, lives will be saved.
Remember the big fuss about a hybrid Polar Bear/Grizzly being shot and proving the end of the world was happening.
Nevermind.
It was just a blonde Grizzly after all.
All the hubris last month about polar bear x grizzly hybrids, based on an unusual-looking bear killed near Arviat, has turned out to be wishful thinking by those who’d like to blame everything to do with polar bears on climate change. An awful lot of “experts” now have egg on their faces. That “hybrid” was just a blonde grizzly, as I warned it might.

Two years a I posted on Waste Heat as a major source of warming. Last year I noted that the counties with shrinking populations are cooler. Now there is a major paper on waste heat.
The greenhouse effect isn’t the only thing warming things up. There is also the waste heat released when we generate and use energy – even clean energy. Yet the regional impact of that heat – which moves from warm buildings, engines and power plants into the world around us – has not been well accounted for. A new study now shows waste heat may explain some temperature variations at a national scale better than do global climate change models.
Generating and using energy produces waste heat that warms the environment. National energy consumption can be reflected in national temperature variations, according to a new study.
Generating and using energy produces waste heat that warms the environment. National energy consumption can be reflected in national temperature variations, according to a new study.
“This is a major source of climate change that has not been looked at,” said John Murray of The Open University in Milton Keynes, England and lead author of the new study accepted for publication in Earth’s Future, a journal of the American Geophysical Union. “Any kind of energy consumption generates heat” Murray said.
To tease apart the waste heat signal, Murray and co-author Douglas Heggie of the University of Edinburgh compared national temperatures in Japan and the United Kingdom with global temperature trends and with energy consumption from 1965 to 2013. They focused on Japan and the U.K. because as island nations, they are more isolated than mainland countries and more likely to stew in their own waste heat.
The researchers found that for both countries, waste heat explains national climate variations: national temperatures track better with energy use than with global temperature trends. The data showed a correlation between a temperature drop in the U.K. and the current economic recession, which has caused a reduction in energy use there, Murray said. The study also found Japan’s steadily growing energy consumption parallels the worldwide increase in carbon dioxide levels.
The scientists caution that both countries are rather extreme cases: Japan has the 8th highest mean energy consumption in the world and the U.K. has the 13th. Of the two nations, Japan has a warmer climate and therefore less need to heat buildings.
Britain, on the other hand, shows a more pronounced local temperature variation, being a cold enough place to require indoor heating for about six months each year. There is also more cloud cover in the U.K. than in Japan, and those clouds hold waste heat closer to the ground, where it can raise the temperature.
“The correlation of temperature above background levels and national energy consumption is very high,” concluded Murray. This suggests that energy consumption should be factored into the national climate change projections of any densely populated country, he said.

If you could wouldn’t you want the Earth to be 1C colder?
What? You don’t?
