According to the World Meteorological Organization (WMO) State of Global Climate Report for 2024, unprecedented levels of sea heat, ice melt and ocean levels are one of the main measures of climate change, which are dangerous records in recent years.
“We saw record temperatures in broad areas,” says John Kennedy On WMO. Some of the resulting changes will take up hundreds or thousands of years, warning in the report.
The report set a serious list of unwanted records. For example, the increase in sea level has doubled since the satellite measurement begins, growing between 2015 and 2024 from 1993 and 2000 to 4.7 mm per year growing from 2.1 mm per year.
With the biggest disadvantage of the glacier month over a period of three years in the last three years, the glaciers are losing snow faster than before. Disadvantages in Norway were particularly large – including Sweden and tropical ends, including the northern archipelago of Swalbard.
18 years with the lowest limit of summer sea ice in the Arctic Ocean were in the last 18 years, and three years with the lowest range of sea ice around the Antarctic continent in the last three years.
Warning Kennedy, “What happens in the pole, not necessarily in the stick,” warns Kennedy, which means that changes in these areas can affect the climate around the entire planet.
A new record for the heat of the ocean – an important solution is how much additional heat is accumulating – each of the last eight years has been set in each one. And the 10 hottest years on the record were in the last 10 years.
The report also stated that 2024 was probably the first calendar year to heat up 1.5 ° C compared to the pre-industrial era, with an average global close temperature of 1.55 ° C above an average of 1850 to 1900, plus or minus 0.13 ° C. In measurement, it means that it is also a chance that it was not more than 1.5 ° C.
Kennedy says that one year above a year from this value does not mean that the 1.5 ° C target set in the Paris Agreement has been dissolved. While not clearly defined, most climate scientists agree that it refers to the average temperature on something like 20 years instead of a year.
The report also underlines three methods, which are believed to define when we have crossed the Paris target. According to these, the global climate is now 1.34 ° C, 1.37 ° C or 1.41 ° C as compared to 1850 to 1900.
Error straps for these three methods, however, are sufficient for all more than 1.5 ° C, meaning that there is a small chance that we have already exceeded the 1.5 ° C Paris target. Kennedy says, “We cannot rule 1.5 in these ways.”
