Exploring Hydrocarbon Depletion
Annual global temperature change (thin light red) with 11 year moving average of temperature (thick dark red). Temperature from NASA GISS. Annual Total Solar Irradiance (thin light blue) with 11 year moving average of TSI (thick dark blue). TSI from 1880 to 1978 from Krivova et al 2007. TSI from 1979 to 2015 from PMOD (see the PMOD index page for data updates).

For those interested, here's the relevant graph that shows how solar irradiance has been flat to decreasing for over 50 years while global temps have been increasing markedly over the same period...so...it's not increases in solar activity are responsible for the current warming.
your credibility hovering near zero.
In executive order, Trump to dramatically change US approach to climate change
Washington (CNN)President Donald Trump will sign a sweeping executive order Tuesday at the Environmental Protection Agency, which looks to curb the federal government's enforcement of climate regulations by putting American jobs above addressing climate change.
The order represents a clear difference between how Trump and former President Barack Obama view the role the United States plays in combating climate change, and dramatically alters the government's approach to rising sea levels and temperatures -- two impacts of climate change. .....
.....Tuesday's order will initiate a review of the Clean Power Plant initiative, rescind the moratorium on coal mining on US federal lands and urge federal agencies to "identify all regulations, all rules, all policies ... that serve as obstacles and impediments to American energy independence," the official said.
Pruitt: Trump to sign order on power plant regulations Tuesday
Specifically, the order will rescind at least six Obama-era executive orders aimed at curbing climate change and regulating carbon emissions, including Obama's November 2013 executive order instructing the federal government to prepare for the impact of climate change and the September 2016 presidential memorandum that outlined the "growing threat to national security" that climate change poses. .....

The idea is that climate change doesn’t merely increase the overall likelihood of heat waves, say, or the volume of rainfall — it also changes the flow of weather itself. By altering massive planet-scale air patterns like the jet stream (pictured above), which flows in waves from west to east in the Northern Hemisphere, a warming planet causes our weather to become more stuck in place. This means that a given weather pattern, whatever it may be, may persist for longer, thus driving extreme droughts, heat waves, downpours and more.
(Complex life only evolved about 600 million years ago,iirc)If we burn all the fossil fuels “not only will the resultant climate change be faster than anything Earth has seen for millions of years, the climate that will exist is likely to have no natural counterpart, as far as we can tell, in at least the last 420 million years...
...climate today is changing at rates well above the geological norm. If humanity fails to tackle rising CO2 and burns all the readily available fossil fuel, by AD 2250 CO2 will be at around 2000 ppm — levels not seen since 200 million years ago.
However, because the Sun was dimmer back then, the net climate forcing 200 million years ago was lower than we would experience in such a high CO2 future. So not only will the resultant climate change be faster than anything Earth has seen for millions of years, the climate that will exist is likely to have no natural counterpart, as far as we can tell, in at least the last 420 million years.”” — Gavin Foster
Four years of current emissions would be enough to blow what’s left of the carbon budget for a good chance of keeping global temperature rise to 1.5C.
That’s the conclusion of analysis by Carbon Brief, which brings the Intergovernmental Panel on Climate Change’s (IPCC) carbon budgets up to date to include global CO2 emissions in 2016.
Our infographic above shows how quickly the budgets for 1.5C, 2C and 3C will be used up if emissions continue at the current rate. For 1.5C, this could be a soon as four years’ time.

There’s momentum in the energy system; there’s momentum in the climate.
We really are committed to that second degree fairly clearly already.
the thawing of frozen cropland burps nitrous oxide into the atmosphere at rates far greater than previously thought, meaning agriculture’s role in producing the greenhouse gas has been greatly underestimated, according to University of Guelph research.
Nitrous oxide — commonly known as laughing gas and used as a dental anesthetic — accounts for well under 10 per cent of greenhouse gas emissions. But it’s almost 300 times as potent as carbon dioxide at trapping energy, the greenhouse effect believed to be warming the planet.
