Unprecedented over the sea, ice melting and sea level rise are among the many important goals of climate change that set alarming items in recent years, according to the World Meteorological Organization’s (WMO) state of the global climate report for 2024.
“We saw record temperatures across wide areas,” says John Kennedy at WMO. Turning some of the resulting changes would take hundreds or thousands of years, the report warns.
The report indicates a bleak list of unwanted items. For example, the rise in the sea level is double -sated satece satellite measurements began, which increased from 2.1 millimeters a year between 1993 and 2000 to 4.7 mm a year between 2015 and 2024.
Glaciers lose ice faster than ever, with the great loss of glaciers for a three -year period that occurs in the last three years. Losses were especially large in Norway – including the Northern Archipelago of Svalbard – as well as in Sweden and the tropical Andesbjerg.
The 18 years with the lowest extent of the Summer Sea in the Arctic Sea were for the past 18 years, and the three years with the lowest extent of sea ice, the Antarctic continent was the last three years.
“What happens in the rod that does not necessarily remain in the rod,” warns Kennedy, which means that changes in these areas can affect the climate around the entire planet.
A new record for sea heat – a central measure of how much additional heat has accumulated – has been set in each of the last eight years. And the 10 hottest years on the record were the last 10 years.
The report also notes that 2024 was probably the first calendar year that was 1.5 ° C warmer than the pre-industrial era, with an average global near-surface temperature of 1.55 ° C over the average 1850 to 1900, plus or minus 0.13 ° C. This ucentily in the survey means there is also a chance that it was warmer than 1.5 ° C.
A single year above this value does not mean that the 1.5 ° C dimensions set in the Paris TAG have been broken, says Kennedy. Although not clearly defined, most climate scientists agree that it refers to the average tempèry compared to something like 20 years instead of a single year.
The report also outlines three methods that are considered to define when we have exceeded the Paris goal. According to these, the global climate is now 1.34 ° C, 1.37 ° C or 1.41 ° C warmer than the average from 1850 to 1900.
However, the error beams for these three methods are all wide enough to exceed 1.5 ° C, which means there is a small chance that we have already exceeded the 1.5 ° C Paris target. “We cannot exclude 1.5 by these methods,” says Kennedy.
