Soot cooling the planet.

One of the things about climate change is the way that particles in the atmosphere (aerosols) keep the temperature down. I was first alerted to the statistics when it was reported that after the 9/11 disaster, the USA grounded aircraft for three days and the temperature went up 1C. Whether this was true or not the combination of soot particles from burning coal, farming and aircraft contrails do have a combined effect in shielding the earth’s surface from the suns heat and suppressing the temperature.  The big question is by how much?
Another anecdotal story is that when I was living in the UK in the 1970’s the temperature had been stable or even falling for forty years and this was accepted, when we had a message from New Zealand (probably Kevin Trenberth) that the temperature was rising steadily. This was all before satellites.
Looking at the NASA graph the pause in temperature from about 1940 through to about 1980 can be seen quite clearly. This was when the world was gearing up after World War 2 and coal plants were working round the clock to rebuild the economy. From 1980 Europe and the USA stated to clean up their cities by switching from coal to cleaner energy and the atmosphere began to clear and the temperature restarted its upwards path.
There may well be other factors such as El Niño’s and similar cycles of the major oceans but I would suggest that there could easily be an extra 1.0 C increase in temperature built into the system for when we stop burning coal and cut back on flying.

I really wouldn't bother using the Nasa Giss graph. It's been adjusted to hell just to fit the CAGW narrative. The data really can't be trusted:

You are obviously a climate denier and can make up as much stuff as you like to suit your narrative. The NASA figures are very much in line with the satellite information from the European Space Agency Copernicus program and also from the Japanese Meteorology satellites. If its a conspiracy it involves thousands of scientists world wide, about fifty governments and dozens of satellite programs. Who says that it is rubbish> Fox News and a few Republican politicians.

If you don't like NASA try the European Space Agency or the Japanese. Or is this a conspiracy that includes the whole world apart from you and one or two chosen few?

Thanks for that insight on how soot & aerosols are affecting temperatures.

As the B.B.C reported yesterday in 2015 renewables surged to record levels with over 8 million people are now working in renewable energy worldwide. So it will be interesting to see how the reduction in aerosols affects global temperatures on top of natural variation and green house gases. Another effect of soot is contributing to the darkening of the Arctic ice sheet, thus lowering the albedo affect and causing more heat to be absorbed. After the ongoing remarkably early seasonal wildfires around the taiga this year, it will also be interesting to see the drone footage from the "Dark Snow Project" and read about the findings. A project well worth to subscribing to in light of governments and media missing the scientific opportunity. I look forward to reading their findings in Peter Sinclair's "Crock of The Week" column as well as Slate and other decent media outlets.

Renewable energy surges to record levels around the world.

Hi Bob. I think everyone is looking at the Arctic ice melt this year as it has started from a very low level.. 2012 took a deep dive in June/July so we will see how 2016 reacts.

I also posted on this two weeks ago. Trouble every where we look.

I think you are looking at the 1950-1970 Pacific Inter-decal Oscillation, where the Earth cooled (held steady temperatures). There was another one called the Global Warming Hiatus, where the warming rose less aggressively. After this period, the climate took off where it left off making the Hiatus look like it never happened.

I was born in 1951 and it was cold during my young adult life and today no one in St Louis buys a sled or ice skates.

* No ice on the Mississippi that the iceman cut and sold all year for iceboxes. Today the iceman would go bankrupt.
* No Midwest blizzards. No winter temperatures below 0°F (-18°C, the freezing point of salt water).
* Summer temperatures above 100°F (38°C) and who can sweat to keep cool at temperatures above body temperature.
* In Germany, all the ski runs in the Stuttgart area are unusable because of no snow. In Turkey, all the old ladies were wearing sweaters in Bor on the plateau despite the temperature being above 100°F (38°C) and my wife said Bor had been cool and they could not adjust to the change.

I know the climate changed from the stable period between 1950-1970.

You may be right about the Pacific Inter-decal Oscillation but the aerosols in the atmosphere block the suns heat and keep it cool by about 0.5 C in the industrial areas and where there is a lot of air traffic. This is just a side issue compared to what is happening to the climate as a whole.
