Carbon dioxide is shrinking uppermost atmosphere

Starting around 60 km up, in the outermost layers of atmosphere carbon dioxide actually cools the atmosphere, causing it to shrink and contract. A cooling and shrinking MLT will lead to an increase in the longevity of space debris at higher altitudes

The Biggest Increase in Global CO2 Emissions Ever Recorded

The increase in global CO2 emissions of over 2 billion metric tons in 2022 is the largest in history in absolute terms, more than offsetting the previous year's pandemic-induced decline.

Greenhouse gas concentrations hit a new record in 2020

The global average of carbon dioxide concentrations hit a new high of 413.2 parts per million last year, according to the WMO report. It was higher than the annual average over the last decade, despite a 5.6% drop of CO2 due to Covid.

Carbon dioxide peaked at record levels

Scientists from Scripps and the NOAA reported that levels of atmospheric carbon dioxide peaked in May, reaching a monthly average of nearly 419 parts per million.

Atmospheric CO2 Passes 420 PPM for First Time Ever

The concentration of atmospheric CO2 surged past 420 parts per million for the first time in recorded history this past weekend, according to a measurement taken at the Mauna Loa Observatory on Hawaii.

CO2 levels in atmosphere rising despite pandemic

The industrial slowdown due to the COVID-19 pandemic has not curbed record levels of CO2. Carbon dioxide levels saw another growth spurt last year past 410 parts per million on average.

Heat-trapping carbon dioxide in air hits new record high

The world hit another new record high for heat-trapping carbon dioxide in the atmosphere, despite reduced emissions because of the coronavirus pandemic, scientists announced Thursday.

CO2 levels just reached the highest level in human history

For the first time since humans existed on earth, carbon dioxide has exceeded 415 parts per million.

Carbon levels on Earth not seen in 56 million years

A new study finds we are pumping CO2 into the atmosphere at a rate nine to 10 times higher than the greenhouse gas was emitted during the Paleocene-Eocene Thermal Maximum, a global warming event that occurred 56 million years ago.

Global carbon dioxide emissions have climbed in 2018

Renewable energy capacity has hit record levels and global coal use may have already peaked. But the world's CO2 emissions from fossil fuels increased in 2018, and the trend places global warming targets in jeopardy.

Higher CO2 levels may lead to decreased nutrients in rice

Scientists have discovered that increased levels of atmospheric carbon dioxide may lead to lesser amounts of nutrients, such as essential B vitamins, in rice.
