I reported recently that the IPCC is publishing this year its fifth assessment report (AR5). The last working group has published its own report and it has come to the climate change solutions we have to put in place.
The good news is : it’s going to be really cheap, only a mere, tiny, itsy bitsy 0.06 percent of global GDP per annum. The bad news : we have to act fast or it is will either impossible or really expensive.
As I have reported before, clean energy prices have decreased sharply in the past few years, so now is the best time to go massively in solar, wind and energy efficiency.
We – ie. all people from all countries on Planet Earth – have to get moving on slashing our greenhouse gases emissions NOW. Large emitters such as G20 countries and the largest companies have a lot to do quickly to prevent the worse from occuring.
If in the last ten years a lot has been done on renewables such as wind or solar – as an example of that, 26% of all solar PV capacity in the world was installed just in the past 12 months: 38 out of 145 GW! – much much more has to be done in the next few years.
