Yet more examples of poor journalism:

REGION: Global warming can be delayed four decades, study finds

Abrupt and potentially deadly climate change can be delayed about 40 years without the need for enormously costly cuts in carbon dioxide emissions, according to a new study by a team including scientists at Scripps Institution of Oceanography.

Cutting back on non-CO2 contributors to climate change will push back the threshold for reaching a dangerous level of global warming, stated the study, published Monday in the Proceedings of the National Academy of Sciences. Its authors include Mario Molina and Veerabhadran Ramanathan of the institution, part of UC San Diego. […]

Note the bolded and italicized words I’ve highlighted.

Now, what does the actual paper say in its title and abstract:

Reducing abrupt climate change risk using the Montreal Protocol and other regulatory actions to complement cuts in CO2 emissions:

[…] We discuss strategies for short-lived non-CO2 GHGs and particles, where existing agreements can be used to accomplish mitigation objectives. Policy makers can amend the Montreal Protocol to phase down the production and consumption of hydrofluorocarbons (HFCs) with high global warming potential. Other fast-action strategies can reduce emissions of black carbon particles and precursor gases that lead to ozone formation in the lower atmosphere, and increase biosequestration, including through biochar. These and other fast-action strategies may reduce the risk of abrupt climate change in the next few decades by complementing cuts in CO2 emissions.

Someone needs to tell the North County Times writer that “complementing” does not mean “without the need”.
