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

Exciting technology converts CO2 into ethylene

A company seeks to replace the non-renewable and pollutive process of creating ethylene with its new technology that uses carbon dioxide instead.

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.

A Membrane That Separates CO2 From Other Gases

Scientists have developed a new type of self-assembling silver membrane that could be used to capture carbon dioxide (CO2) emissions before they have a chance to spread in the atmosphere.

COVID-19 Pandemic Caused Unprecedented Fall Of CO2

As the COVID-19 pandemic continues, scientists have predicted that global carbon dioxide emissions may drop by more than 5 percent in 2020—in what would be the largest fall since the end of the Second World War.

Cement production makes more CO2 than all the trucks in the world

Low-carbon geopolymer cement can reduce CO2 by up to 90 percent. But it costs three times as much as the usual cement and nobody is buying it.

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.

Scientists turn carbon dioxide back into coal

Scientists have harnessed liquid metals to turn carbon dioxide back into solid coal, in research that offers an alternative pathway for safely and permanently removing the greenhouse gas from our atmosphere.

Greenhouse gas levels reach record highs, UN says

Average concentrations of carbon dioxide hit new highs of 405.5 parts per million (ppm) in 2017, up from 403.3 ppm in 2016 and 400.1 ppm in 2015, levels not seen for millions of years.

Cities With The Biggest Carbon Footprints

According to the latest study by the Norwegian researchers - Seoul (South Korea), Guangzhou (China) and New York City leads the world in its global carbon footprint.
