Young Guns: Reduce, Reuse, Recycle

Over time, mankind has degraded the planet's most valuable resource - its atmosphere. Now it is time to do something

From unusual wildfires across the globe to the unprecedented heatwave of Siberia, the impact of climate change were felt in every corner of the globe in 2020. Humanity has now come to a “moment of truth,” United Nations Secretary-General Antonio Guterres said in his State of the Planet speech in December. “COVID and climate have brought us to a threshold.”

The amount of carbon dioxide in the atmosphere reached record levels in 2020, hitting 417 parts per million in May 2020.

The last time CO2 levels were consistently at or above 400 parts per million was around four million years ago, during the Pliocene era, when the world was 3ºC warmer and sea levels were 10-25 meters (33-82 feet) higher than they are today.

“We are seeing record levels every year,” says Ralph Keeling, head of the CO2 programme at the Scripps Institution of Oceanography, which has been monitoring CO2 concentrations from the Mauna Loa observatory in Hawaii since 1958. “We saw record levels again this year despite COVID-19.”

In the three years since 195 nations pledged in Paris to cap global temperature increases at 2 degrees Celsius, a few things have become unmistakably clear.

The world must quickly phase out the fossil fuel industry. And that is no longer enough.

We need CO2 removal strategies that also act as an essential bridge to a clean-energy future.

“CO2 removal has gone from a moral hazard to a moral imperative,” says Julio Friedmann, senior research scholar at the Center for Global Energy Policy at Columbia University.
