Stop burning fossil fuels now: there is no CO2 'technofix', scientists warn

Researchers have demonstrated that even if a geoengineering solution to CO2 emissions could be found, it wouldn't be enough to save the oceans

German researchers have demonstrated once again that the best way to limit climate change is to stop burning fossil fuels now.

In a "thought experiment" they tried another option: the future dramatic removal of huge volumes of carbon dioxide from the atmosphere. This would, they concluded, return the atmosphere to the greenhouse gas concentrations that existed for most of human history - but it wouldn't save the oceans.
