The global treaty to save the ozone layer has also slowed Arctic ice melt

Grist

The 1987 Montreal Protocol, which phased out the production and use of chemicals that were depleting the ozone layer, has long been considered one of the most successful environmental treaties in history. New research finds that the global pact achieved another unforeseen benefit: delaying the melting of Arctic sea ice.

Risk, doubt, and the burden of proof in the climate debate

GreenBiz

At one such event in 2014, speaker Christopher Monckton surveyed the room and declared that everyone there agreed that humanity’s "emissions of CO2 and other greenhouse gases have contributed to the measured global warming since 1950." His point was to make it clear that "we are not climate change deniers."

Planned UK spaceports could add significantly to emissions of climate-warming gases

Envirotec Magazine

Black carbon alone has a climate warming potential between 460-1,500 times that of CO2, and can last in the atmosphere for up to 12 days. Black carbon contributes to global warming by converting incoming solar radiation into heat, which can have detrimental effects on cloud formation and rainfall patterns.

Prevention: A profitable mindset when it comes to gas leaks

Envirotec Magazine

CFCs have a high chlorine content and have been linked strongly to ozone depletion and global warming. HCFCs were considered an improvement when they were first introduced, as they have lower chlorine and make a lesser contribution to ozone depletion and global warming. Green hydrogen.

UK substantially underestimates its methane emissions from oil and gas production – and many other countries probably do too
