An old post that is this relevant:
NO TURNING BACK POSSIBLE
Today we reach GSG level for + 1.6 C
The IPCC does a wonderful job of compiling climate studies, but their level of communication is abysmal. (Like many scientists)
A report of a few thousand pages, an executive summary of 80 pages and an executive summary of 20 pages that is too dense.
NO GOING BACK
A mistake of environmentalists is to use current climatic disasters to argue that if we want to avoid them in the future, we must act now.
Only vegetation can capture CO2 from the air, and currently we produce about twice as much CO2 as nature can absorb. So the upheavals we are currently experiencing represent the minimum of what the future holds for us.
TODAY we have added + 1.6 C
<10 years to avoid a warming of more than 1.5 C> or even recently <Emissions must be capped by 2025> (IPCC)
Currently GHGs induce a thermal imbalance of 3 watts per sq. m. of earth surface, and as said above, this is a phenomenon that cannot be reversed.
For an object, to emit 1 watt more of thermal radiation per m2, its temperature must increase by 0.016 C, so for the earth to be in thermal equilibrium with the ‘current’ level of GHGs, its temperature must increase by 0,48 degree. Added to the current 1.2 degrees, we are between +1.6 and +1.7 C. Of course the earth has a very high thermal inertia, so this balance would be reached in 20, 30, 50 years, but it is thing done, no turning back is possible!
We have taken big steps. Last year, more than double the nominal capacity of clean electricity production (wind and solar) than fossil capacity was installed.
Except that :
Solar farms yield of 15 to 25% on their nominal power, wind farms between 30 and 45%, while the average production of generators varies between 60 and 90%. So this year there is twice as much ‘new electricity’ produced via carbon burning as from clean energy sources.
– To have no new sources of electricity that produce GHGs, solar, wind and hydro installations must be tripled. Note that biomass is not a carbon neutral solution.
– To begin to significantly reduce the surplus CO2 emitted each year and hope to return to a balance with nature in 20-40 years, we must multiply the production of electricity without GHG emissions by a factor of ten.
Wind-Do Energy offers several innovative solutions to increase the penetration of clean energies. Out of 60 funding applications that we presented to Cleantech-oriented VCs, none asked us about our potential for reducing GHG emissions.
