The United Nations recorded summer 2023 as the hottest summer in history with average temperatures certainly higher than the previous record.

July - August 2023 is the hottest period since researchers began monitoring temperatures in 1940, according to data from the European Union's climate change agency (Copernicus Climate Change Service). ). Copernicus said the global average temperature this summer is 16.77 degrees Celsius, 0.66 degrees Celsius higher than the average from 1990 to 2020, and also breaking the previous record set in August 2019. (difference of nearly 0.3 degrees Celsius), according to CNN.
This is the first set of scientific data to confirm the inevitable reality. The Northern Hemisphere recorded hot summers in many places, including the US, Europe and Japan, with many record-breaking heat waves and unprecedented high ocean temperatures.
"Scientists have long warned that fossil fuel consumption will accelerate climate change. Extreme weather is hitting every corner of the planet," said António Guterres, secretary general of the United Nations. Quoc, said.
According to Copernicus, it is estimated that both July and August 2023 will be 1.5 degrees warmer than pre-industrial times. That is the key threshold that scientists warn the world not to cross in order to prevent the most catastrophic impacts of climate change.
"The Northern Hemisphere has experienced a summer full of extreme events, with heat continuously sparking wildfires, threatening health, disrupting daily life and having long-term impacts on the environment," Petteri Taalas , secretary general of the World Meteorological Organization, commented.
Countries in the Southern Hemisphere also experienced unusually warm winters with temperatures much higher than average in Australia, some South American countries and Antarctica. Global average ocean temperatures are also at record highs, fueling major storms in the Atlantic and Pacific.
With 4 months remaining, 2023 is currently the second warmest year in history, only 0.01 degrees Celsius less than 2016. Scientists predict that 2024 will definitely be even hotter with the raging of El Nino, Natural climate fluctuations bring warmer-than-average land-sea temperatures and affect the weather.
