Record-Breaking Temperatures Ahead

New Delhi: According to a recent report from the World Meteorological Organization (WMO), 2026 is projected to be one of the four hottest years recorded, with the global average temperature from January to September 2026 reaching 1.47 degrees Celsius above pre-industrial levels, specifically the average from 1850 to 1900.

This temperature surpasses the annual averages recorded in 2025 and 2023, and is only marginally lower than the record-setting year of 2024.

The report indicates that temperatures are expected to continue rising through the end of 2026, primarily due to the intensifying El Niño phenomenon, which has been gaining strength since August and is anticipated to be the strongest on record by December.

Released on the first day of this year's UN climate conference, COP31, in Antalya, Turkiye, the WMO's 'State of the Climate Report' highlights alarming trends.

WMO Secretary General Celeste Saulo noted that the last four years have marked the warmest period in the 177-year history of climate observations, with ocean temperatures breaking records for the tenth consecutive year.

The ongoing El Niño is expected to be one of the most powerful ever recorded, contributing to elevated temperatures and extreme weather patterns that may persist into 2027.

The report attributes the rise in global temperatures to an increasing energy imbalance on Earth, with the planet accumulating heat at an accelerating pace.

This imbalance has reached unprecedented levels, as greenhouse gases trap significant amounts of heat, disrupting the balance between incoming solar energy and outgoing energy.

The atmospheric concentration of carbon dioxide has surged by 53% since 1750, rising from approximately 278 parts per million (ppm) to around 426.8 ppm in 2025. Similarly, methane levels have increased by 167% from 729 parts per billion (ppb) in 1750 to 1,948 ppb in 2025.

The oceans are absorbing 90% of the excess heat, and 2026 is on track to be the tenth consecutive year of record ocean warmth.

The report also emphasizes the impact of extreme weather events on communities, food security, and poverty, leading to displacement in various regions.

For example, heatwaves, droughts, and wildfires in Europe have resulted in over 30,000 excess deaths, according to preliminary estimates.

In India, around 146.5 million people faced extreme heat during an April 2026 heatwave, as reported.

UN Secretary-General Antonio Guterres remarked, 'We have entered a new age of climate extremes. A supersized El Niño is colliding with a planet already superheated by manmade climate change. Climate records keep falling, and the human costs keep rising.'

He urged leaders to take decisive action by reducing emissions, transitioning away from fossil fuels, and providing necessary support to vulnerable nations.
