Broken record: March is 10th straight month to be hottest on record, scientists say

WASHINGTON — For the tenth consecutive month, Earth in March set a brand new month-to-month report for world warmth — with each air temperatures and the world’s oceans hitting an all-time excessive for the month, the European Union local weather company Copernicus stated.

March 2024 averaged 14.14 levels Celsius (57.9 levels Fahrenheit), exceeding the earlier report from 2016 by a tenth of a level, in line with Copernicus knowledge. And it was 1.68 levels C (3 levels F) hotter than within the late 1800s, the bottom used for temperatures earlier than the burning of fossil fuels started rising quickly.

Since final June, the globe has damaged warmth information every month, with marine warmth waves throughout giant areas of the globe’s oceans contributing.

Scientists say the record-breaking warmth throughout this time wasn’t fully stunning resulting from a robust El Nino, a climatic situation that warms the central Pacific and modifications world climate patterns.

“However its mixture with the non-natural marine warmth waves made these information so breathtaking,” stated Woodwell Local weather Analysis Middle scientist Jennifer Francis.

With El Nino waning, the margins by which world common temperatures are surpassed every month ought to go down, Francis stated.

Local weather scientists attribute a lot of the report warmth to human-caused local weather change from carbon dioxide and methane emissions produced by the burning of coal, oil and pure gasoline.

“The trajectory is not going to change till concentrations of greenhouse gases within the environment cease rising,” Francis stated, “which implies we should cease burning fossil fuels, cease deforestation, and develop our meals extra sustainably as rapidly as potential.”

Till then, anticipate extra damaged information, she stated.

Underneath the 2015 Paris Settlement, the world set a aim to maintain warming at or under 1.5 levels Celsius (2.7 levels Fahrenheit) since pre-industrial instances. Copernicus’ temperature knowledge is month-to-month and makes use of a barely totally different measurement system than the Paris threshold, which is averaged over two or three a long time.

Samantha Burgess, deputy director of Copernicus, stated March’s record-breaking temperature wasn’t as distinctive as another months previously yr that broke information by wider margins.

“We have had record-breaking months which were much more uncommon,” Burgess stated, pointing to February 2024 and September 2023. However the “trajectory just isn’t in the precise path,” she added.

The globe has now skilled 12 months with common month-to-month temperatures 1.58 levels Celsius (2.8 levels Fahrenheit) above the Paris threshold, in line with Copernicus knowledge.

In March, world sea floor temperature averaged 21.07 levels Celsius (69.93 levels Fahrenheit), the very best month-to-month worth on report and barely larger than what was recorded in February.

“We’d like extra bold world motion to make sure that we are able to get to internet zero as quickly as potential,” Burgess stated.
