After an unusually intense heat wave, downpour or drought, Noah Diffenbaugh and his research group inevitably receive phone calls and emails asking whether human-caused climate change played a role. In the past, scientists typically avoided linking individual weather events to climate change, citing the challenges of teasing apart human influence from the natural variability of the weather. In a new study, published in this week's issue of Proceedings of the National Academy of Sciences, Diffenbaugh and a group of current and former Stanford colleagues outline a four-step "framework" for testing whether global warming has contributed to record-setting weather events. In order to avoid inappropriately attributing an event to climate change, the authors began with the assumption that global warming had played no role, and then used statistical analyses to test whether that assumption was valid. The Stanford research team, which includes a number of former students and postdocs who have moved on to positions at other universities, has been developing the extreme event framework in recent years, focusing on individual events such as the 2012-2017 California drought and the catastrophic flooding in northern India in June 2013. One high-profile test case was Arctic sea ice, which has declined by around 40 percent during the summer season over the past three decades.
Climate change has been a big factor for the contribution for the weather being weird and different. The weather should not be weird and should not be having storms due to the cause of climate change. We should start taking control of our actions and start making the world a better place to live in. The weather should be normal and should not be changing due to our actions.
