[15] [16] In mid-January 2023, weather forecasts regarding the probable occurrence of the El Niño phenomenon in 2023 and 2024 were published in various media. [ 17 ] [ 18 ] [ 19 ] Given that Earth's average temperature has already increased by 1.2 °C since pre-industrial times, a large enough El Niño event in 2023-2024 could even push the ...
Projected global surface temperature changes relative to 1850–1900, based on CMIP6 multi-model mean changes. The IPCC Sixth Assessment Report defines global mean surface temperature (GMST) as the "estimated global average of near-surface air temperatures over land and sea ice, and sea surface temperature (SST) over ice-free ocean regions, with changes normally expressed as departures from a ...
The following is a list of weather events that occurred on Earth in the year 2023. The year saw a transition from La Niña to El Niño, with record high global average surface temperatures. The several weather events which had a significant impact were blizzards, cold waves, droughts, heat waves, wildfires, floods, tornadoes, and tropical cyclones.
The biggest factor in the hurricane forecast apart from El Niño is the water temperatures across the Atlantic basin, which are running well above average in many areas. Warm water is the fuel for ...
During the first half of the month, temperature departures from the historical average for this time of year trended between 0.5 and 2.5 degrees below zero Fahrenheit for major cities such as ...
The mercury is forecast to reach 90 F more times in 2023 than in 2022 in several major cities, including Chicago, where the temperature hit the 90-degree mark 16 times in 2022, right around the ...
The temperature on land rose by 1.59 °C while over the ocean it rose by 0.88 °C. [3] In 2020 the temperature was 1.2 °C above the pre-industrial era. [4] In September 2023 the temperature was 1.75 °C above pre-industrial level and during the entire year of 2023 is expected to be 1.4 °C above it. [5]
2023's June-July-August season was the warmest on record globally by a large margin, as El Niño conditions continued to develop. [16] September 2023 was the warmest September on record globally, with an average surface air temperature 0.5 °C above the temperature of the previous warmest September (2020). [17]
