Unprecedented levels of ocean heat, ice increase and sea level rise are among many major climate change measures that are concerned in recent years, according to the state of the World Meteorological Organization (WMO) for the Global Climate Report 2024.
“We have seen record temperatures across large areas,” he says, says John Kennedy In wmo. The report warns that the reversal of some of the resulting changes will take hundreds or thousands of years.
The report defines a bleak list of unwanted records. For example, the average sea level has doubled since the start of satellite measurements, as it increased from 2.1 mm annually between 1993 and 2000 to 4.7 mm per year between 2015 and 2024.
Ice rivers lose ice faster than ever, with the greatest loss of ice mass in a three -year period in the past three years. The losses were particularly great in Norway – including the northern archipelago in Svles – as well as in Sweden and the tropical platform.
The 18 years of the years have reached the lowest range of summer sea ice in the northern ocean over the past 18 years, and the three years have been the lowest range of marine ice around the Antarctica in the past three years.
“What is happening in the poles does not necessarily remain in the Polish,” Kennedy warns, which means that changes in these areas can affect the climate around the entire planet.
A new record for Ocean Heat – a main measure of the additional temperature accumulated by the planet – has been set in each of the past eight years. The ten -year -old years have been on the past ten years.
The report also indicates that 2024 may have been the first calendar year with a warmer by 1.5 ° C from the pre -industry era, with an average global temperature semi -superficial 1.55 ° C above 1850 to 1900, in addition to or minus 0.13 degrees Celsius. This is not certain in the measurement means that there is also a chance that was not warmer than 1.5 ° C.
Kennedy says that one year is higher than this value does not mean that the target 1.5 ° C stipulated in the Paris Agreement has been hacked. Although it is not clearly identified, most climate scientists agree that it indicates the average temperature over 20 years instead of one year.
The report also shows three ways to determine when we exceeded the goal of Paris. 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.
The error tapes of these three roads, however, are all wide enough to exceed 1.5 ° C, which means that there is a small opportunity we have already exceeded the goal of Paris 1.5 degrees Celsius. “We cannot exclude 1.5 with these methods,” says Kennedy.
