Against the background of the discussion on Carbon Dioxide Removal, the question arises as to whether there are also technologies to remove methane (CH4) from the atmosphere (Methane Removal), which is 30 times more harmful to the climate. Methane is converted into CO2 in the atmosphere by natural oxidation processes with an average residence time...

Mit dem Pariser Klimaabkommen von 2015 hat sich die Staatengemeinschaft verpflichtet, die globale Erwärmung auf deutlich unter 2°C zu begrenzen. Der Weltklimarat geht inzwischen aber davon aus, dass die bisher beschlossenen Massnahmen zur Reduzierung der Treibhausgasemissionen nicht genügen, um den menschengemachten Klimawandel in den Griff zu beko...
