Adaptation, mitigation activities can control climate change – I.P.C.C. report

Climate change irreversible impacts to increase, however, there are options to adapt to climate change and stringent mitigation activities to manage it, finds new Intergovernmental Panel on Climate Change report.

The Synthesis Report, which sums and integrates the findings of the I.P.C.C. Fifth Assessment Report produced by 800 scientists (see related story), is the most comprehensive assessment of climate change.

“Our assessment finds that the atmosphere and oceans have warmed, the amount of snow and ice has diminished, sea level has risen and the concentration of carbon dioxide has increased to a level unprecedented in at least the last 800,000 years,” said Thomas Stocker, co-chair of I.P.C.C. Working Group I.

The document reports with great certainty than in previous assessment the fact that emissions of greenhouse gases and other man-made drivers have been the dominant cause of observed warming since the mid-20th century.

According to the report, the more human activity disrupts the climate, the greater the risks. Continued GHG emissions will further warm and create long-lasting changes in all components of the climate system, increasing the likelihood of widespread and profound impacts affecting all levels of society.

“Adaptation can play a key role in decreasing these risks. Adaptation is so important because it can be integrated with the pursuit of development, and can help prepare for the risks to which we are already committed by past emissions and existing infrastructure,” said Vicente Barros, co-chair of I.P.C.C. Working Group II.

But adaptation alone is not enough. Substantial and sustained reductions of GHG emissions are at the core of limiting the risks of climate change, as it will not only reduce the rate and magnitude of warming, but also increase the time available for adaptation.

According to experts, there are multiple mitigation pathways to achieve the substantial emissions reductions over the next few decades that will limit the warming to 2 degrees Celsius. But delaying mitigation to 2030 will severely increase the challenges associated with limiting the warming.

“It is technically feasible to transition to a low-carbon economy. But what is lacking are appropriate policies and institutions. The longer we wait to take action, the more it will cost to adapt and mitigate climate change,” said Youba Sokona, co-chair of I.P.C.C. Working Group III. – EcoSeed Staff
