The entire planet sweltered for the two unofficial hottest days in human record keeping on Monday and Tuesday, acording to University of Maine scientist at the Climate Reanalyzer project.
Continuing an astonishing series of record-breaking warming events this year, the past Monday and Tuesday, July 3 and July 4, have been measured to be the hottest two days for the earth ever. July 3 was the first time that the global average daily temperature crossed the 17 degree Celsius mark. That record was broken within a day, with July 4 turning out to be even hotter.
The average temperature on July 3 was measured to be 17.01 degree Celsius. The next day recorded 17.18 degree Celsius.
“The increasing heating of our planet caused by fossil fuel use is not unexpected, it was predicted already in the 19th century after all,” said climate scientist Stefan Rahmstorf at the Potsdam Institute for Climate Research in Germany. “But it is dangerous for us humans and for the ecosystems we depend on. We need to stop it fast.”
The daily but preliminary and unofficial heat record comes after months of “truly unreal meteorology and climate stats for the year,” such as off-the-chart record warmth in the North Atlantic, record low sea ice in Antarctica and a rapidly strengthening El Nino, said University of Oklahoma meteorology professor Jason Furtado.
This global record is not quite the type regularly used by gold-standard climate measurement entities like the National Oceanic and Atmospheric Association. But it is an indication that climate change is reaching into uncharted territory. It legitimately captures global-scale heating and NOAA will take these figures into consideration when it does its official record calculations, said Deke Arndt, director of the National Center for Environmental Information, a division of NOAA.
“In the climate assessment community, I don’t think we’d assign the kind of gravitas to a single day observation as we would a month or a year,” Arndt said. Scientists generally use much longer measurements — months, years, decades — to track the Earth’s warming. In addition, this preliminary record for the hottest day is based on data that only goes back to 1979, the start of satellite record-keeping, whereas NOAA’s data goes back to 1880.
But Arndt added that we wouldn’t be seeing anywhere near record-warm days unless we were in “a warm piece of what will likely be a very warm era” driven by greenhouse gas emissions and the onset of a “robust” El Nino. An El Nino is a temporary natural warming of parts of the central Pacific Ocean that changes weather worldwide and generally makes the planet hotter.
