So can we be climate optimists? In 2024, we could see a decline in global carbon emissions for the first time in history.
This could be the year… global CO2 reduces
Hot topic: Scientists think 2023 could go down in history as the peak in our greenhouse gas emissions. Glossary
New year's resolution - A goal you set for yourself at the start of a new year.
Greenhouse gas - Gases in the Earth's atmosphere that trap heat, contributing to global warming. Carbon dioxide, methane, nitrous oxide and water vapour are all greenhouse gases.
