The UN said Sunday that each of the last eight years will be hotter than the previous year.
Sea level rise, glacier melt, torrential rains, heat waves, and the deadly disasters they cause have all accelerated, the World Meteorological Organization said in a report.
The UN chief described the report as a chronicle of climate chaos.
Since the late 19th century, Earth has warmed more than 1.1 degrees Celsius, with half of that increase occurring in the past 30 years.
The goal of nearly 200 nations gathered in Egypt is to hold the rise in temperatures to 1.5 Celsius.
This year is on track to be the fifth or sixth warmest ever recorded despite the impact since 2020 of La Nina, which cools the atmosphere in the Pacific.
The worse the impacts, the more the warming is.
The ocean's surface water hit a record high temperature in 2021.
Coral reefs and the half a billion people who depend on them for food and livelihoods were at risk from the rising marine heat waves.
The report states that 55 percent of the ocean surface experienced at least one marine heatwave in the last four years.
Sea level rise has doubled in the past 30 years due to melting ice sheets and glaciers.
The British Antarctic Survey's science leader said that the messages in the report could barely be worse.
As the climate system begins to break down, records are being shattered all over our planet.
Methane has shown the largest one-year jump ever recorded, and greenhouse gases are all at record levels.
Natural gas leaks and a rise in beef consumption are to blame for the rise in methane emissions.
Climate change wreaked havoc on communities across the globe.
The floods in Pakistan that left a third of the country under water were preceded by a two-month heat wave in South Asia. There were at least 1,700 deaths and 8 million displacements.
The last four wet seasons in East Africa have been the longest in 40 years.
Falling water levels disrupted or threatened commercial river traffic along China's Yangtze, the Mississippi in the US and several major inland waterways in Europe.
Poorer nations that are most vulnerable to the effects of climate change suffer the most.
"But even well-prepared societies this year have been ravaged by extremes, as seen by the heatwaves in Europe and southern China."
In the European Alps, melt records have been shattered with an average thickness loss of between 3 and over 4 meters, the most ever recorded.
Since 2001, Switzerland's glacier volume has gone down.
