Explanatory note: Obama may highlight coal but, given that climate change and ocean acidification are consequences of pumping geospheric carbon* into the biosphere, the priority must be to eliminate the most carbon intensive sources first. That means phasing out tar sands and coal as soon as possible. Hence the title to this post.
*i.e. carbon that has been out of circulation within the biosphere for millions of years, which has given rise to atmospheric CO2 levels unprecedented in millions of years. It really is that simple.
In the run up to the United Nations Climate Change Conference COP 21 scheduled for December 2015, 24 of the UK’s foremost academic institutions, including the Geological Society have published a joint Climate Communiqué calling on national governments to take immediate action if they want to avert the serious risks posed by climate change. The document states that to tackle climate change, governments, including that of the UK, must seize the opportunity at climate talks in Paris in December to negotiate an agreement based on the latest scientific evidence. Pointing to that scientific evidence, the organisations say that if we are to have a reasonable chance of limiting global warming in this century to 2°C relative to the pre-industrial period, we must transition to a zero-carbon world by early in the second half of the century.
Therefore we are already in breach of Article 2 (i.e. the objective) of the UNFCCC:
“…to achieve… stabilization of greenhouse gas concentrations in the atmosphere at a level that… prevent dangerous anthropogenic interference with the climate system…”
