Extreme weather moving to the mainstream?

Researchers are proposing that weather extremes – by their nature rare events – will become more likely as a result of climate change. Weather extremes such as droughts, floods and heatwaves highlight our vulnerability, but it has always been noted that it is difficult to link a particular extreme event to anthropogenic climate change. However, work conducted at the Swiss Federal Institute of Technology tries to address this limitation. Their research suggests that a 2⁰C increase in global temperatures could mean that 40% of extreme rainfall events would be caused by human-induced climate change. The authors believe their work could be used in climate change risk assessments, reaching decisions about liability and setting mitigation targets.
