Message in a frozen bubble: Antarctic ice reveals abrupt rises in atmospheric CO2 in the ancient past

Today's atmospheric carbon dioxide (CO2) levels are higher than ever during at least the last 800'000 years. More importantly, the atmospheric levels of this greenhouse gas continue rising at a speed that is unparalleled in our planet's recent geological history. Intensifying extreme weather events and... click to read more

A newly discovered (microscopic) global source of methane

The average temperature on Earth rose dramatically during the last century. This is due to human activity, which led to the increased atmospheric concentration of certain gases, typically called greenhouse gases. These gases increase the solar heat trapped by our planet. The greenhouse gas methane... click to read more
