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 →

Understanding Sea Level Rise, p3: it’s about timescales, speed of change & carbon budget – world aims for 29-55m sea level rise

In our previous article of the series we’ve looked at an overview of global sea level rise forecasts for the year 2100 – and seen that these forecasts have a very large spread, and also seem to increase with time … 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 →

Climate Record Update: Did northern hemisphere breach +2C climate target in early March, or did we ‘just’ breach +1.5?

Baselines, baselines, baselines, everyone. What goes for emission reduction targets also goes for temperature measurements: Let’s stick together! The graph in our first post had some fawlty measurements. But we STILL breached pre-industrial +2(!) Take a close look at below … Continue reading →

‘2 degrees climate target fails because politicians cannot handle a margin of scientific uncertainty’

The identified critical threshold for dangerous climate change saying that the increase in global temperature should be below 2 degrees Celsius seems not to have helped the climate negotiations so far. New research from the University of Gothenburg and Columbia … Continue reading →
