Finger at Global Warming for the Deadly Heatwave that Scorched North America – IndraStra Global

Challenges aside, scientists soon got to work on what caused the scorching temperatures in the United States and Canada. By conducting rapid attribution analysis, researchers from the World Weather Attribution (WWA) group determined that such a spike in temperatures would be “virtually impossible without climate change.”
Scientists used enormous quantities of weather data and cutting-edge climate models to compare what happened in the existing world, which has warmed about 2 degrees Fahrenheit since the rise of industry and its accompanying emissions, to a hypothetical world in which humans had never pumped any greenhouse gases into the atmosphere.
Results from the study showed that the heatwave, even though rare, was far more likely to occur in the current warmed world than in a world without warming. And if it had occurred in such a hypothetical world, it would not have been as hot.
“What we are seeing is unprecedented. You’re not supposed to break records by four or five degrees Celsius,” said Friederike Otto, of the Environmental Change Institute at Oxford University, one of the climate scientists involved in the study. “This is such an exceptional event that we can’t rule out the possibility that we’re experiencing heat extremes today that we only expected to come at higher levels of global warming.”
Climate Change Science, the latest Sustainable Development Industry Report from the Al-Attiyah Foundation, takes an in-depth look at the scientific developments that have allowed us to chart global warming with greater accuracy.
