2025 Hottest Year Amid Climate Inaction
2025 is shaping up to be one of the hottest years ever recorded.
Despite warnings from scientists, world leaders have not taken enough action to stop climate change.
This means the planet is heating up faster than expected, which could lead to very dangerous conditions for people and nature.
For example, by the end of the century, the temperature could rise by 3 degrees Celsius, making it very hard for people to live in some places.
India is especially at risk, with temperatures projected to rise by 4.1 degrees Celsius.
The good news is that renewable energy like solar and wind power is growing quickly, which might help solve the problem if we use it more.
However, India's CO₂ emissions are a growing concern, potentially doubling by 2030 if not controlled.
2025 is on track to be one of the hottest years on record, with global temperatures 1.54°C above pre-industrial levels in November.
There is a 5% chance of the world heating up by 3°C by the end of the century, which would have devastating impacts like deadly temperatures and ecosystem collapse.
India has seen a temperature increase of 0.89°C over the past century and could face a 4.1°C increase by 2100 if emissions are not controlled.
Despite slow progress from governments, renewable energy sources like solar and wind outpaced global energy demand by 9% in the first half of 2025.
India emits about 3.6 gigatons of CO₂ annually, a figure that could nearly double by 2030 if left unchecked.
