The world's oceans have absorbed more than 90% of the excess heat generated by human activities, leading to a widespread decline in ocean health and affecting marine life.

According to the Intergovernmental Panel on Climate Change (IPCC), global greenhouse gas emissions reached a record high of 55 gigatons of CO2 equivalent in 2019.

The frequency of extreme weather events, such as heatwaves, droughts, and heavy rainfall, has increased by about 20% since the 1980s.

The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) estimates that up to one million plant and animal species are at risk of extinction due to human activities, including climate change.

Arctic sea ice has declined by about 13% per decade since the late 1970s, and the Arctic Ocean could be ice-free in summer as early as the 2040s.

The average global sea level has risen by about 8 inches (21 cm) since 1880, with about 3 inches (7.5 cm) of that rise occurring in the last 25 years. The sea level is projected to rise by another 1 to 4 feet (0.3 to 1.2 meters) by the end of this century.

According to the Global Risk Report 2021 by the World Economic Forum, the economic costs of climate change are estimated to reach trillions of dollars per year in the coming decades, affecting businesses, governments, and communities globally.
