Actually, it's been happening regionally in the U.S., Europe, and Japan for two decades, but 2014 was the first year GLOBAL GDP went up while GLOBAL carbon emissions went down.

Why's that matter?

Because it shows shifting from fossil fuels to renewables won't damage the global economy.

I.e., Lawson is clueless about the science, nor does he grasp the financial aspects of the on-going transition to renewable energy.

Meanwhile, next time you're asked, "How much global warming is due to humans?", you can honestly say, "about 220%". That's right - 220%!

How so? Because on a 100 year time scale, the only major warmers are greenhouse gases, the main driving gas being CO2 (H2O is also major, but, being entirely passive, is not a driver).

Meanwhile, each year Earth manages to absorb 55% of the man-made CO2. So, the 45% that remains airborne is what's been raising atmospheric CO2 (by 2.1 parts per million by volume each year, or 43% since 1850). So, the man-made contribution to the main global warming driver is 220% or more than twice as much as what stays in our air.

What this means is humans are entirely responsible for ALL the global warming in the modern era, and then some.

Remember this when some skeptic questions man's contribution to global warming.

What led scientists to this conclusion? Several separate lines of evidence that coalesce to yield the above conclusion. What evidence? In summary, the following:

Beyond rising surface temperatures, we know the Earth must be warming because the INCOMING energy has been exceeding the OUTGOING energy for many decades;

Yet, INCOMING energy has fallen slightly, and the stratosphere has been cooling, which says the warming can't be due to excess solar energy, like some global warming deniers keep claiming;

Also, CO2 and other greenhouse gases not only block OUTGOING energy, but they do so with a measured spectrum that closely matches the expected drop in the spectral lines, were the decrease due to increased CO2 and other greenhouse gases. That's like a fingerprint. So, from the above, we know that the buildup in green house gases is what's causing the warming.

We also know that man-made CO2 exceeds volcanic CO2 by more than 10,000%; the CO2 buildup can't be due to volcanoes. There are no other natural CO2 sources that haven't been in close balance with CO2 sinks for several millenia. So, the CO2 buildup is UNNATURAL, meaning it's man-made.

Plus, we also know that plants absorb carbon12 preferentially. Burning fossils (dead plants buried for eons) releases C12. And the measured drop in the C13/C12 ratio also says that the excess CO2 has been induced mostly by humans burning fossil fuels (oil, gas, coal).

And while solar energy has fallen, deforestation has also added about 10 to 15% excessCO2, and cement production another 5% or so.

All of which is yet another way of showing that, since about 1850, all the global warming has been entirely man-made.
