Leading voices in the global warming debate discuss the issue of climate change at London’s Thames barrier, as the latest IPCC report states that it is “extremely likely” humans have been the principal cause of warming since the 1950s.
Leading scientists today said they were more certain than ever before that humans are the main culprits for climate change and predicted the impact from greenhouse gas emissions could linger for centuries.
The Intergovernmental Panel on Climate Change (IPCC) said in a report that the current hiatus in warming, when temperatures have risen more slowly despite growing emissions, was a natural variation that would not last.
It said the Earth was set for more heatwaves, floods, droughts and rising sea levels that could swamp coasts and low-lying islands as greenhouse gases built up in the atmosphere.
Many world leaders called for stronger action to rein in rising greenhouse gas emissions and limit a rise in temperatures to within manageable limits after the report, which estimated that humanity has burnt more than half the available carbon.
The study, meant to guide governments in shifting towards greener energies, said it was “extremely likely”, a probability of at least 95 percent, that human activities were the dominant cause of warming since the mid-20th century.
