The US Intergovernmental Panel on Climate Change (IPCC) will release today (30th September) a report which reviews the scientific evidence for climate change and its causes, however, a summary and key findings have already been released and read by policy makers. The summary has stated that ‘warming of the climate system is unequivocal, and since the 1950s, many of the observed changes are unprecedented over decades to millennia. The atmosphere and ocean have warmed, the amounts of snow and ice have diminished, sea level has risen, and the concentrations of greenhouse gases have increased.’
The report has concluded by saying ‘it is extremely likely [95% confidence] that human influence has been the dominant cause of the observed warming since the mid 20th century.’
Environmental and Energy Study Institute
In response to the summary, EESI Executive Director Carol Werner said the following;
‘It is time to wean ourselves off fossil fuels. It is time to match our policies and our actions to what science is telling us. It is time to listen to the voices of local leaders who already are facing the impacts of climate change on their vulnerable communities.’
US Department of Energy
Secretary of Energy Ernest Moniz said the following in response to Friday’s summary;
‘I believe that the report is a watershed; we have clear evidence from our climate scientists that global warming is happening and that we as humans are playing a critical role, which is the underpinning of the President’s Climate Action Plan. The plan places a strong emphasis on mitigating the risks of climate change through further investments in clean technologies aligning with our all of the above energy strategy, The President’s plan also brings forward a strong focus on the need to prepare for climate change because we are already experiencing the anticipated impacts of global warming.’
Lead author of the report
Peter Thorne, the lead author on attribution and observation for the IPCC has spoken about the report to EurActiv and made the following follow up comments;
‘If you have change which is that large everywhere, and you’ve built infrastructure to cope with today’s climate, there will inevitably be implications of adaptation and mitigation.
‘It is beyond doubt that if we want to avoid climate change exceeding two degrees centigrade, we need policy makers to implement mechanisms that ensure a large amount of carbon remains under the ground.’
