2025 Among Hottest Years Amid Climate Challenges
Scientists say 2025 was one of the hottest years ever because of climate change caused by humans.
This is the first time the average temperature over three years was higher than the limit set by the 2015 Paris Agreement, which aims to keep the Earth's temperature from rising more than 1.5°C.
Extreme weather events like heat waves, wildfires, and floods happened more often and were more severe.
These events caused a lot of damage and made it hard for people to prepare and respond.
The United Nations climate talks did not make a clear plan to stop using fossil fuels, and different countries are making different amounts of progress in fighting climate change.
Some countries are using more renewable energy, while others are still using coal, oil, and gas.
Scientists say we need to do more to stop the Earth from getting too warm.
2025 was one of the three hottest years on record, breaking the 1.5°C threshold set by the Paris Agreement.
Extreme weather events, including heat waves, wildfires, and floods, were more frequent and severe due to climate change.
The three-year temperature average exceeded the 1.5°C limit for the first time, highlighting the worsening climate crisis.
Global climate negotiations in Brazil ended without a clear plan to transition away from fossil fuels.
Different countries are making varying progress in climate action, with some investing in renewables and others supporting fossil fuels.
