I highly recommend this (frightening) meta-analysis
These 'missing charts' may change the way you think about fossil fuel addiction
I can't imagine a scenario where things go right. Even if Tesla gets all the capital and ressources it needs, the situation is deteriorating too fast. I'm a huge Tesla supporter, but the crisis that's bound to happen will disrupt Tesla like any other organization/institution.
At this pace, innovation in EV and solar energy won't cut it.
Thanks for posting this. The author is taking a skeptical view of the data, which I believe is well deserved. Particularly this risk of under reporting warrants concern.
The author is, however, overlooking BP's estimate of CO2 emissions from energy sources. Many countries are attempting to switch to lower emissions fuel, coal to natural gas mostly. While I am concerned about a long term lock-in of gas, in the short run this switch should be slowing growth in carbon emissions even as total consumption of fossil fuels rise. So the estimate of carbon emissions is supposed to track this. The author fails to report that this estimate has been flat for the last three years, suggesting that we may be at a peak in emissions from fossil fuels. This fact does not seem to support the aithor's thesis. But had he reported it, he could still claim that it was subject to insert reporting errors.
So what really is the arbiter here? I agree with the author that measurement of atmospheric CO2 levels is our best yard stick for measuring progress in curbing emissions. It is comprehensive across all sources of emission, and is certainly not fooled by bad accounting elsewhere. Moreover, atmospheric CO2 is what physically impacts climate change. The disadvantage are that we cannot separate different sources humans and natural, and it is a bit noisy.
So here are actual estimates of annual change in atmospheric CO2 as measured at the Mauna Loa Observatory. The second column is the increase in ppm.

Notice that the increments have been growing for decades, but they are noise from year to year. The trend basically is in line with BP's estimates of carbon emissions from fossil fuels. This confirms the validity of BP's metric AND is consistent with the theory emissions from fossil fuels is a prime driver of the accumulation of carbon in the atmosphere. But because these data are noisey, it is good to average a few years at a time to dampen the noise. So we see a peak here of about 3ppm/y in 2015 and 2016. Nicely 2017 is down to 2.13ppm. Does that mean we are post peak? It's too soon to say. It could just be some random variation. However, taken together the last four years do seem consistent with the view that carbon emissions from fossil fuels have been level from 2014 thru 2016. They may have even dropped in 2017, and come June we will see what BP reports to confirm this.
It will take many more years to see if 2015-16 really was the inflection point in atmospheric CO2 or whether the climb really will continue to accelerate. Clearly this is no time for complacency, but I am cautiously hopeful that emissions may have peaked. Lots of models out there would suggest otherwise.
In this thread, we have had alot of discussion around when various peaks will happen. Coal and residual fuel oil seem well into decline. Diesel looks to peek by 2021 or earlier, and gasoline will peak about 5 years after diesel. I think the natural gas peak will be linked to rise of stationary storage, but have not yet worked out a model for this. Basically, within about 5 years there will be virtually no new gas plants built because wind and solar paired with battery storage will be so cheap. So my impression is that natural gas demand will have peaked by 2030. Putting all these peaks together carbon emissions from fossil fuel look to be declining through most of the next decade. The decline will seem slow at first, but accelerate as exponential growth gains scale.
So I remain cautiously optimistic, and I'll be watching to see what BP reports in June.
