The goal of limiting global warming to 1.5 degrees Celsius is crucial, as even a small increase can have significant impacts. The Paris Agreement, signed by 193 parties in 2015, aims to keep temperature rise below this threshold. Currently, the planet is already 1.1 degrees warmer than pre-industrial levels.
If temperatures rise by 1.5 degrees, 69 million people will be affected by rising sea levels, while 80 million will be affected at 2 degrees. Heat waves will impact 14% of the population at 1.5 degrees, increasing to 37% at 2 degrees. Additionally, biodiversity loss and extreme weather events will worsen.
To achieve the 1.5-degree target, global emissions must be reduced by 45% by 2030 and reach zero by 2050. Immediate action is essential to minimize the worst effects of climate change.
