It's possible July could be the hottest month in 120,000 years: climate scientist
, the first time a summer month was more than one degree Celsius hotter than normal.
Although Wednesday's presentation, embargoed until Thursday morning, came days before the end of the month, scientists are looking ahead to what they expect the final data to show.According to Haustein's data, which combines information from multiple weather agencies, this month is expected to between 1.3 and 1.7 C above the average global temperature calculated before humans began burning fossil fuels.
Haustein said a weather monitoring product combined historical observations from around the world with current temperatures registered by the Global Forecast System, to predict whether July would exceed the 2019 record.Scientists said they knew this July is likely to be the hottest in recent times, so they then looked to see whether they could calculate if it will be the hottest in the Earth's history.
"To say, 'Is it the warmest for the last 100 years, or 1,000, or even 10,000 years?' It's a trickier question to answer," Haustein said. "Before 1850 we didn't have these observations, at least not enough to say something meaningful about the global mean.
"There's a decent chance that this month essentially is the hottest known since the paleo records," he said.The consequences of the warming planet are playing out across the world not only in terms of the heat records broken but through floods, wildfires and severe storms, scientists say.
