Last month was the third-hottest June on record globally, temperature data suggest, confirming 2017 will almost certainly make a hat-trick of annual climate records, with 2015, 2016 and 2017 being the three hottest years since records began.
Trump’s anti-science and anti-climate agenda doesn’t come as a surprise; before he even took office, there were early signs that Trump would put public health at risk by scrapping climate and other environmental policies.
The First Climate Model Turns 50, And Predicted Global Warming Almost Perfectly
A notable amount of station-level temperature records were broken during February, including numerous cities setting warm daily and monthly temperature records. There were 11,743 daily warm temperature records broken or tied, compared to 418 daily cold records. Of those, 1,151 daily records also broke the warmest temperature record ever observed during February, compared to just 2 cold records.
In a few days the Arctic’s beleaguered sea ice cover is likely to set another grim record. Its coverage is on course to be the lowest winter maximum extent ever observed since satellite records began. These show that more than 2 million square kilometres of midwinter sea ice have disappeared from the Arctic in less than 40 years.
The globally averaged temperature over land and ocean surfaces for January 2017 was 0.88°C (1.58°F) above the 20th century average of 12.0°C (53.6°F). This was the third highest January temperature in the 1880–2017 record, behind 2016 (highest) and 2007 (second highest).
“There’s a clear trend where those extreme hot days across the continent are increasing, and quite dramatically over the past 20 years.”
