It is not all the time simple to know the present local weather disaster by way of easy, simple details – not with so many variables at play – however this is a worrying stat for you: each single month of the final 12 has set a brand new international temperature file for that month.
NASA has confirmed that Might 2024 adopted April, March, February, and January in hitting new highs by way of common international temperatures. Earlier than that, June by means of December 2023 had achieved precisely the identical.
A streak like this has by no means been seen earlier than for so long as information have been stored, and it is a sign of the speedy warming that our planet is now experiencing. What’s much more sobering is that there is worse to come back.
“It’s clear we are facing a climate crisis,” says NASA administrator Invoice Nelson. “Communities across America – like Arizona, California, Nevada – and communities across the globe are feeling first-hand extreme heat in unprecedented numbers.”
Data are being smashed all throughout the board, however there is no trigger for celebration. Final November, the worldwide common temperature was greater than 2 °C hotter than pre-industrial ranges for the primary time, whereas the US simply recorded its warmest ever winter.
Regardless of the proof that our planet’s local weather is shifting drastically, humanity is pumping out extra greenhouse fuel emissions than at any level in historical past. We’re hurtling in direction of a local weather cliff edge and exhibiting no indicators of slowing down.
There is no doubt it is a development, both. As NASA factors out, the final 10 consecutive years have been the warmest 10 since we began preserving information on the finish of the nineteenth century. Earlier than this new year-long streak, the most well liked run occurred between 2015 and 2016, lasting seven months.

“We’re experiencing extra scorching days, extra scorching months, extra scorching years,” says Kate Calvin, chief scientist and senior local weather advisor at NASA. “We all know that these will increase in temperature are pushed by our greenhouse fuel emissions and are impacting individuals and ecosystems all over the world.”
A powerful El Niño climate sample that began early in 2023 is prone to have pushed a few of these excessive temperatures, and the indicators are that because it wanes, we’d see an finish to month after month of record-setting temperatures, a minimum of for now.
Tens of hundreds of meteorological stations and devices – unfold throughout Earth on land, ships, and buoys – are used to take the readings that NASA publishes. The numbers are then processed to account for the distances between readings in addition to different potential components, resembling city warmth islands.
If there’s a optimistic to be discovered right here, it is that we’re getting higher at monitoring the worldwide local weather image, at making sense of the information, and at predicting what may occur subsequent. Now all we have to do is do one thing about it.
“We are providing critical climate data to better lives and livelihoods, and benefit all humanity,” says Nelson.
