Climate Change & Anthropocene Extinction 48: large biodiversity benefits of 1.5 degrees limit (IPCC)

Then of course we also have our climate-ecology series that wanted an update based on IPCC SR15. Judging by IPCC’s special report on 1.5 degrees the ecological benefits of strengthening the global climate target from 2 to 1.5 degrees are … Continue reading

Understanding Sea Level Rise 6: SLR benefits of keeping warming below 1.5 degrees (IPCC & Pattyn)

If you do one about agriculture, you gotta do one for your sea level rise series too, we heard you say.

Climate & Agriculture 6: Global agricultural benefits of keeping warming below 1.5 degrees (IPCC)

Yes, while the human population keeps growing, climate change is likely to cause various detrimental effects on global agriculture and thereby food security. Like other climate change impacts these effects will increase with the magnitude of the warming, and most … Continue reading

Climate Change & Anthropocene Extinction 32: COP23 emission targets still lead beyond +3 degrees

Climate change is just one driver of the Holocene-Anthropocene Mass Extinction. But it will be a powerful one, as global emission reduction commitments – that will be discussed in the following two weeks in the German city of Bonn during … Continue reading

Do the math! Because climate sensitivity is logarithmic, 1.5 degrees target was already breached at 400 ppm – if you look at CO2 only (& assume ECS = 3C)

According to ‘conventional climate science’ the currently already emitted amount of CO2 (404 ppm) leads to a committed warming of 1.56 degrees Celsius. To keep ‘the promise of Paris’ – the CO2 concentration must go down, down to below 400 … Continue reading

Real Global Temperature Trend, p22 – World still on course for dramatic 3 degrees warming, need to more than double reduction speed

Let’s keep this one short, because in essence there’s nothing new. Before the start of the Paris climate summit we saw that if you combine all the world’s nations’ 2025 & 2030 emission reduction targets you get to a pathway … Continue reading

Real Global Temperature Trend, p21 – Science is ruthless. We have ‘about zero’ years of emissions to stay below 1.5 degrees

That is if you correct for one important piece of scientific criticism to the below graph. But even if you prefer to ignore what may seem the nitty gritty of climatology and accept a maximum global carbon budget of 8.9 … Continue reading

Real Global Temperature Trend, p19 – There is hot, hotter, hottest – and 2016: dangerously close to pre-industrial +1.5 degrees…

The 19th edition of our global temperature trend series is ‘just a graph’. That is because we are still overwhelmed by Break Free 2016. And because some graphs simply speak for themselves. The progression of the 2016 hottest year global … Continue reading

Real Global Temperature Trend, p11 – Under agreed 1.5 degrees target world has 8 years of emissions for rest of century

And that understanding has just ended the Age of Coal. Thank you coal – it’s been great fun. We’ll have to leave the rest of you where you’ve been for the previous millions of years. In our quest to uncover … Continue reading

#BreakFree2016 – If 6 countries would stop exporting coal, that would be very helpful

Just 6 countries: The United States, Colombia, South Africa, Russia, Indonesia and Australia. If somehow we could sprinkle (perhaps shake) a little common sense, the rest of the world would be deprived of imports of the most polluting and CO2-intensive fossil fuel … Continue reading
