Air travel and carbon dioxide emissions went down for a bit, but the world continues to burn amid a global climate emergency.

In November 2019, the journal BioScience published an article co-signed by over 11,000 scientists that declared a global climate emergency.

The paper presents the latest trend lines for both human-related activities like carbon dioxide emissions and Brazilian Amazon forest loss as well as environmental indicators such as greenhouse gas concentrations in the atmosphere and loss of ice mass in Greenland and Antarctica.

The data shows a COVID-related dip in air travel, world gross domestic product and carbon dioxide emissions, but also finds record levels of carbon dioxide and methane in the atmosphere, increases in livestock numbers and ocean acidification as well as the shocking loss of ice around the world, from glaciers and ice sheets to the near disappearance of summer Arctic sea ice.

"Likely because of the pandemic, fossil fuel consumption has gone down since 2019, as have carbon dioxide emissions and airline travel levels.
