After months of debate and reviews of a mass of scientific reports, the UN’s Intergovernmental Panel on Climate Change (IPCC) has this last week produced its long debated (second) report on the effects of a warming planet. The report includes a summary of the ten “climate related drivers of impacts” – see figure below.
The report is clear and deeply worrying and affects all of us. No country can avoid the ‘overwhelming’ impact of climate change, but most at risk are those living in low lying areas where rising sea levels will force mass migrations of population to other areas.
Other results of our unwillingness to cut back on carbon emissions will mean tundra regions will warm and polar ice caps melt, crop levels will be affected and fish catches will be smaller. The BBC’s website provides an excellent summary of the report. (http://www.bbc.com/news/science-environment-26810559)
It’s obvious that despite the evidence of the Impact of global warming on our climate and on future generations, there has been since 2009 – when we first started commenting on this issue on this blog – a growing reluctance by many governments to take the robust actions we need to avert the growing crisis.
Perhaps because of this, Chris Field, the Chair of the IPCC Committee indicates that effective actions can actually be taken. For instance we can build defences against rising sea levels and locally cut CO2 emissions. These actions will require in the words of the report ‘ambitious investment’, but politicians and the constituencies they serve need to understand that in the long run this is the safest and only route that we can take.
