Unprecedented rise in Arctic temperatures this winter: How will this affect global weather patterns?

Arab Weather - The World Meteorological Organization warned in a new climate report that global warming will continue over the next five years, with temperatures expected to remain at or near record levels, deepening climate risks to global societies and economies and threatening sustainable development paths.

Worrying indicators for the years 2025-2029

The report highlighted a set of key messages that highlight the seriousness of the upcoming climate phase, the most important of which are:

There is an 80% chance that one of the next five years (2025-2029) will set a new record as the “hottest year on record,” surpassing the record set in 2024.

There is also an 86% chance that one of the next five years will see a temperature increase of 1.5°C compared to the pre-industrial average (the period from 1850 to 1900).

In the same context, climate models show a 70% probability that average global warming during the period (2025-2029) will exceed the 1.5°C barrier.

Long-term warming is still below the 1.5°C threshold.

Despite these alarming projections, the report notes that long-term warming, measured over decades, remains below the 1.5°C limit agreed upon in the Paris Climate Agreement. However, the continued upward trend in temperatures suggests that this limit could be exceeded in the near future if carbon emissions continue as planned.

There is an 80% chance that at least one of the next five years (2025-2029) will break the record for the warmest year on record (set in 2024). There is an 86% chance that temperatures in at least one of the next five years will be 1.5°C warmer than the pre-industrial average. The report does not provide global forecasts for each of these years individually.

An additional fraction of any degree of warming leads to more damaging heat waves, extreme rainfall events, severe droughts, melting of ice sheets, sea ice and glaciers, along with warmer ocean temperatures and rising sea levels.

The Arctic: Warming Faster Than the Global Average

The report indicated that the Arctic region will continue to experience warming rates that exceed the global average, which could lead to significant environmental changes, including melting sea ice and rising sea levels.

Arctic temperatures over the next five winters (November to March) are expected to be more than three and a half times the global average, 2.4°C above the average temperature over the most recent 30-year reference period (1991-2020).

Sea ice forecasts for the period from March 2025 to March 2029 indicate further decreases in sea ice concentrations in the Barents Sea, Bering Sea, and Sea of Okhotsk.

sharp differences in rainfall patterns

The report also indicated that rainfall patterns will witness significant variation across geographic regions, with some areas expected to become wetter, while others may experience more severe droughts, directly impacting agriculture, water, and food security.

South Asia has experienced above-average precipitation in recent years, except for 2023, and this trend is expected to continue during 2025–2029. Note that this situation may not apply to all seasons in each of these five years.

And God knows best.
