Climate Change Science Part 3.1 Carbon Reserves and the Keeling Curve

This series of blogs is based on the Harvard Climate-Energy Challenge MOOC. Previous parts have dealt with the physics involved and anthropogenic changes. Because carbon exists in different forms, whether in the atmosphere as carbon dioxide, in plants and animals as organic carbon or in the ocean as bicarbonate it is useful to think in… Continue reading Climate Change Science Part 3.1 Carbon Reserves and the Keeling Curve

Climate Change Science Part 2 Anthropogenic Changes

To recap from Part 1. This series of blogs is based on the Harvard Climate-Energy Challenge online course (MOOC) via edX which is free unless one wishes to have participation and performance certified. This series of blogs of which this is now the second is intended to extend this freely available content to those who… Continue reading Climate Change Science Part 2 Anthropogenic Changes

December 2018 Global Warming Projections for 2100

Climate Action Tracker updated their end of century forecasts on 11 December in the middle of the Katowice meeting which presumably was not a coincidence. Had there been no actions taken to limit global warming (the 'baseline scenario') they predict the temperature rise by end century above pre-industrial levels would likely be in the range… Continue reading December 2018 Global Warming Projections for 2100

South Africa GHG Emission Reductions – Scaling Up

The South African analysis is the first in a series to be produced by Climate Action Tracker (CAT) comprising three independent research organisations (Ecofys, NewClimate Institute and Climate Analytics) tracking climate action since 2009.  Scaling up refers to the likely measures required to bridge the gap between current emissions projections and Paris compatible pathways. Reports… Continue reading South Africa GHG Emission Reductions – Scaling Up
