Apparently, 4 degrees spells climate doom

One has to wonder though, since CO2 residence time has been said to be anywhere from  five year to hundreds, or even thousands of years, with no solid agreement yet, how they can be so sure of themselves? From the University of Cambridge 4 degree rise will end vegetation ‘carbon sink’ Latest climate and biosphere…

Yes, but weren't climate pledge goals always out of reach?

From the International Institute for Applied Systems Analysis Continuing with pledge pathways to 2030 could push climate goals out of reach Current pledges for greenhouse gas emission reductions are inadequate and will further increase the challenge to reach internationally agreed climate targets, according to new research from a global consortium of 13 international research teams…

2 degree target – a matter of policy guesswork

Success of climate talks vital for 2°C target From the Potsdam Institute – Achieving a global climate agreement soon could be crucial for the objective to keep global mean temperature rise below 2 degrees Celsius. The challenges of meeting the long-term target will otherwise increase drastically both in terms of the required emissions reductions and…

FoS CliSci Summary

Climate Science Newsletter Crowd sourcing A unique effort to assemble a large number of paleo-temperature graphs on all time scales was made earlier on the WUWT Paleoclimate Reference Page and is now continuing with a recent posting (March 30th). ————————— Fixing the Marcott mess Recent issues of CliSci have dealt with the Marcott-Shakun 2013 paper…

Glacially modeled snow job

From the Potsdam Institute for Climate Impact Research (PIK)  Alarmism, I think maybe they are a bit unclear on the concept of how glaciers work. As snowfall varies with the seasons, the flow of ice speeds up and slows down. Besides, it isn’t real data, but just another modeling scenario tweaked for a particular outcome.…

When bankers turn climatologists

From the world bank…sound the general alarm! (sound of klaxons) But see the data at the end. 4-degrees briefing for the World Bank: The risks of a future without climate policy Humankind’s emissions of greenhouse gases are breaking new records every year. Hence we’re on a path towards 4-degree global warming probably as soon as…
