2026 set to be one of the 4 hottest years on record

from Phys.org

The year 2026 continues the protracted streak of exceptional global temperatures, melting ice and rising sea levels, with a very strong El Niño event set to unleash even more heat and extreme weather well into 2027, according to a new report from the World Meteorological Organization (WMO). It highlights the knock-on risks to the environment, economy and everyday life.

explained

The World Meteorological Organization (WMO) is a specialized agency of the United Nations responsible for promoting international cooperation on atmospheric science, climatology, hydrology and geophysics.

The WMO originated from the International Meteorological Organization (IMO), a nongovernmental organization founded in 1873 as a forum for exchanging weather data and research. Proposals to reform the status and structure of the IMO culminated in the World Meteorological Convention of 1947, which formally established the World Meteorological Organization. The Convention entered into force on 23 March 1950, and the following year the WMO began operations as an intergovernmental organization within the United Nations System.

The WMO is made up of 193 countries and territories, and facilitates the "free and unrestricted" exchange of data, information, and research between the respective meteorological and hydrological institutions of its members. It also collaborates with nongovernmental partners and other international organizations on matters related to environmental protection, climate change, resource management, and socioeconomic development.

Headquartered in Geneva, Switzerland, the WMO is governed by the World Meteorological Congress, composed of member states, which meets every four years to set policies and priorities. The Congress is led by an Executive Council led by the President, currently Abdulla Al Mandous of UAE.

how it works

El Niño begins when trade winds weaken and warm surface water spreads east across the tropical Pacific. That water releases heat and moisture into the atmosphere, shifting jet streams and rainfall patterns. Because the ocean then gives heat back to the air, global average temperatures tend to rise in the following months.

so what

Global temperature records are now routinely broken or nearly broken, and an El Niño stacked on top of long-term warming raises the odds that 2027 sets a new high.

fun fact

The WMO is a United Nations agency that dates back to 1873, when its forerunner was set up to share weather observations across borders.
