Sheffield City Council has today reacted to the formal publication of two new reports into the causes and effects of climate change.
The 5th Assessment Report by the Intergovernmental Panel on Climate Change (IPCC) is the most complete assessment ever undertaken of the planet’s climate, set up by the United Nations. The IPCC does not carry out its own research, but bases its assessment on the published work of scientists across the world. The IPCC report is over 2000 pages in length and cites over 9000 scientific publications. It is the most thorough scientific document produced.
It has concluded that [direct quotes]:
• “Warming of the climate system is unequivocal, and since the 1950s, many of the observed changes are unprecedented over decades to millennia.”
• “Atmospheric concentrations of carbon dioxide, methane, and nitrous oxide have increased to levels unprecedented in at least the last 800,000 years.”
• “Human influence on the climate system is clear. It is extremely likely (95-100% probability) that human influence was the dominant cause of global warming between 1951-2010.”
• “Continued emissions of greenhouse gases will cause further global warming and changes in all components of the climate system. Limiting climate change will require substantial and sustained reductions of greenhouse gas emissions.”
• “Most aspects of climate change will persist for many centuries even if emissions of CO2 are stopped.”
At the same time, research published by the Met Office in the academic journal ‘Nature Climate Change’ has found that global warming will lead to drier, hotter summers in the UK, which are more prone to both long droughts and short extreme downpours.
In response, Councillor Jack Scott, the Council’s Cabinet Member for the Environment said: “These new reports provide strong and compelling scientific evidence that climate change is happening, is caused by human activity and will have a devastating impact if urgent action is not taken to reduce our carbon emissions and invest in mitigation.
“It highlights the need for a global, legally binding treaty to cut carbon emissions at the Paris Conference next year. We also need to decarbonise our energy supply and invest massively in clean renewable energy and create green collar jobs.
“Sheffield people remember the awful floods of 2007 and 2010 – these scientific reports are telling us that problems like those are going to happen more often and be even more severe. They paint a very bleak picture for our future, for our city and our planet, unless we take determined, consistent and bold action to reduce carbon emissions now.
“We’ve established a Green Commission to build agreement of what needs to happen and develop a proper plan to make sure we take action on the greatest threat our society faces. As one of the greenest cities, Sheffield needs to be a national leader in this work. We cannot afford to get this wrong.”
