I recommend giving this a chance
I recommend to avoid it. I am sorry to use such generalities on this fine forum, but this is alarmist claptrap posing as science.
Trying to fight the claims one by one is futile, this is pure troll feeding. I will refrain. Take my word for it, global temps will not rise 8 degrees C in the next 10 years. (The headline says 10 but never mind the details). I'm just a nobody , but at least I'm not a liar like these folks, so my word might be good for something.
Note: I dislike anyone who bends science on purpose, whether it's deniers or alarmists, both of whom make a good living out of their evil. I recmmend to avoid reading such sources, and stick to the actual science.
I am open to disscussion because I think thats what science is all about, but if you could provide me with proof to explain why 8 degrees wont happen. That would be of great help. I personally think we are headed for about a 4 C rise by 2050.
On that chart, the top two effects have already occurred, resulting in an estimated warming of 1.9 degrees C since pre-industrial.
Further down the chart, the aerosol masking is not going to go away in an instant, it will take decades to reduce it, as fossil fuel use and wood burning are not going to be instantly reduced to zero. Also, the increased black carbon from forest fires and other impacts of climate change will probably offset the cleaning up of smokestack emissions and the reductions in coal use. So that 2.5 degree change will be closer to zero.
As to increasing CO2 emissions, they tend to take effect slowly (sometimes referred to as the"in the pipeline amount"). The more instantaneous effect has been estimated by climate scientists such as James Hansen as 0.1 to 0.2 degrees per decade.
This chart relies on older estimates of methane release. More recent articles show that even in periods of much higher global warming than we're currently experiencing, such as the Younger Dryas near the last warming maximum from the previous ice age (about 8,000 to 10,000 years ago), the arctic sea ice clathrates didn't melt. Abstract of article is at this link:
https://www.nature.com/articles/nature23316. So again, the feedbacks from increased arctic methane release are much closer to zero than what's shown on that table.
As to the increase in temperature from the albedo changes in the arctic, 1.6 degrees in the next decade seems extremely unlikely. Research in 2014 showed that increases in
Arctic Sea surface temperature from 2000 to 2012 was 0.58 degrees per decade. (Article here:
http://onlinelibrary.wiley.com/doi/10.1002/2013GL058951/full). During that time,
global temperatures, calculated by NASA, increased much less, roughly 0.1 degrees C (data here:
https://data.giss.nasa.gov/gistemp/tabledata_v3/GLB.Ts.txt.
And the water vapor feedback tends to equal the CO2 increase at about a 1:1 ratio. So that 2.1 degrees in the chart should be about 0.1 to 0.2 degrees.
In short, we're much more likely to see a slight increase over current warming (0.1 to 0.2 degrees per decade) in the near future, maybe even a doubling to 0.2 to 0.4 degrees by 2026; not an additional 8 degrees C. So an extinction event (due to climate change) by 2026 is not going to happen. If we continue on the "business as usual" emissions guidelines, an extinction event in a century or so is possible. However, so much progress in renewable energy, battery storage, and other technologies to decarbonize our economies has been made that it's clear that we'll emit far less carbon than the business as usual model assumes.
Even so, the effects of our previous and future emission have lead to climate change and it will get worse over the next few decades. Call me an optimist, but I believe that even with the upcoming troubles ahead, the human race will survive. And posting extremely alarmist articles like the McPherson one just gives ammunition to deniers who will use it to discredit legitimate science when the alarmist projections don't pan out.
It's helpful to read some of the background science and do your own analysis rather than just accept something that shows up on the internet. You can start with the IPCC reports. The latest, AR5, is available at this link:
