What is the News?
The World Meteorological Organization(WMO) has released the Global Annual to Decadal Climate Update Report.
What are the key findings of the report?
Globally
Temperature reaching 1.5 °C: There is a 50:50 chance of the annual average global temperature temporarily reaching 1.5 °C above the pre-industrial level for at least one of the next five years.
– The probability of breaching 1.5 °C was close to zero back in 2015 when the Paris Agreement was adopted, but it has risen steadily since then to 50% now.
Warmest Year: There is a 93% likelihood of at least one year between 2022-2026 becoming the warmest on record and dislodging 2016 from the top ranking.
La Nina: Back-to-back La Niña events at the start and end of 2021 had a cooling effect on global temperatures, but this is only temporary and does not reverse the long-term global warming trend.
– Moreover, any development of an El Niño event would immediately fuel temperatures, as it did in 2016, which is until now the warmest year on record.
Findings related to India
The year 2022 will be cooler (compared to the 1991 – 2020 average) over India, along with Alaska and Canada.
One of the primary reasons for the lowering of temperatures over India from next year is the possible increase in rainfall activity in this decade.
Note: India Meteorological Department (IMD) had also said that the Indian monsoon will soon enter the positive epoch after remaining under a negative epoch since 1971.
