New research reveals rising CO2 levels are disrupting insects, including cotton bollworm moths, ability to select optimal egg ...

Earth inhales and exhales carbon, indicating where and when vegetation is growing (sucking up carbon dioxide) or dying off ...

By analyzing oxygen isotopes in dinosaur teeth, scientists revealed Mesozoic CO₂ highs, plant growth surges, and volcanic ...

Debate has resurfaced as the Trump administration moves to change EPA rules.

Atmospheric CO2 reached an average of 424 parts per million in May, an increase of 3 parts per million over the same time last year. NOAA says this is the fourth steepest single-year climb it has ...

An area with high CO2 levels may put you at higher risk for infection, while a space with low CO2 levels can be considered safer, says University of Colorado-Boulder professor Jose-Luis Jimenez.

As both CO2 and respiratory viruses are present in exhaled air, it makes sense that CO2 concentration is used as a proxy indicator of viral transmission risk. Here, we need to delve a little ...

Carbon dioxide levels in May averaged 424.0 parts per million (ppm) – the fourth-largest annual increase since measurements began 65 years ago at the NOAA observatory in Mauna Loa, Hawaii.

Our rating: False Global temperature and CO2 levels are correlated and both have risen overall since the late 1880s, according to researchers. However, the Earth's average temperature fluctuates ...

The heat-trapping carbon dioxide levels in the air peaked in May, in amounts nearly 50% higher than when the Industrial Age began, and they are growing at a record fast rate, scientists said.
