SOME of the recent extreme weather experienced globally is the result of human induced climate change which will get worse over forthcoming decades, according to a new report from the IPCC.
The Intergovernmental Panel on Climate Change report that greenhouse gas emissions related to mans activities are responsible for more recent record high and less record low temperatures, along with the resultant increase in coastal flooding and likely to the increased extremes of rainfall and snow.
With the United Nations Framework Convention for Climate Change COP17 meeting, in Durban, due to start next Monday the new report summary is timely and prompted this response from Executive Secretary, Christiana Figueres of the UNFCCC:
"The new IPCC report is a stark reminder of the extent to which rising greenhouse gas concentrations and the ensuing rise in global average temperatures are already leading to increased incidences of floods and heat waves, and that such incidences will become more frequent and severe if the global rise in greenhouse gas emissions is left unchecked.
“The ability of the world to become more climate-resilient will largely depend on the speed with which emissions can be decreased.....Governments meeting in Durban for the UN Climate Change Conference must therefore finalise the institutional framework agreed last year in Mexico that can help developing countries adapt to the dire effects of climate change and to curb their emissions. And to curb global emissions, all countries must both answer the question of the future of the Kyoto Protocol and map out a pathway towards a broader, more ambitious, binding global climate change agreement.”
IPCC officials released various statements regarding their findings, which should drive more people to take sustainable action, such as increased energy efficiency.
Regarding the summary of the full report, due to be published later, Qin Dahe, Co-chair of IPCC Working Group I said: “There is high confidence that both maximum and minimum daily temperatures have increased on a global scale due to the increase of greenhouse gases.”
Regarding the future, the assessment concludes that it is virtually certain that on a global scale hot days become even hotter and occur more often.
"For the high emissions scenario, it is likely that the frequency of hot days will increase by a factor of 10 in most regions of the world", said Thomas Stocker the other Co-chair of Working Group I. “Likewise, heavy precipitation will occur more often, and the wind speed of tropical cyclones will increase while their number will likely remain constant or decrease”.
The IPCC report, alongside the IEA’s recent warnings provide plenty of ammunition to the energy efficiency industry to influence commerce, industry and governments to dramatically reduce greenhouse gas emissions and wasted energy through improved use and management of energy and energy intensive processes.
