Carbon dioxide levels are highest in human history | World News,The Indian Express
Growing carbon dioxide levels are more evidence that countries have made little progress toward the goal set in Paris in 2015 of limiting warming to 1.5 degrees Celsius. That’s the threshold beyond which scientists say the likelihood of catastrophic effects of climate change increases significantly.

The amount of planet-warming carbon dioxide in the atmosphere broke a record in May, continuing its relentless climb, scientists said Friday. It is now 50% higher than the pre-industrial average, before humans began the widespread burning of oil, gas and coal in the late 19th century.
There is more carbon dioxide in the atmosphere now than at any time in at least 4 million years, National Oceanic and Atmospheric Administration officials said.
The concentration of the gas reached nearly 421 parts per million in May, the peak for the year, as power plants, vehicles, farms and other sources around the world continued to pump huge amounts of carbon dioxide into the atmosphere. Emissions totaled 36.3 billion tons in 2021, the highest level in history.
As the amount of carbon dioxide increases, the planet keeps warming, with effects like increased flooding, more extreme heat, drought and worsening wildfires that are already being experienced by millions of people worldwide. Average global temperatures are now about 1.1 degrees Celsius, or 2 degrees Fahrenheit, higher than in pre-industrial times.
