Peter Langdon Ward by the Montreal Protocol on Substances that Deplete the Ozone Layer led to the Global Warming Hiatus from 1998 to 2013, during which no statistically significant warming occurred. Warming began again in August 2014 when Bárðarbunga volcano in Central Iceland erupted 85 square kilometers of basaltic lava in six months—the largest effusive volcanic eruption since 1783. As with most effusive volcanic eruptions, this one did not form cooling aerosols in the stratosphere. All of this research is explained in detail at WhyClimateChanges.com, is summarized in a book aimed primarily at non-scientists, What Really Causes Global Warming? Greenhouse Gases or Ozone
Montreal Protocol Parties every year to assess and evaluate various technical issues including evaluating nominations for essential use exemptions for CFCs and halons, and nominations for critical use exemptions for methyl bromide. TEAP’s annual reports are a basis for the Parties’ informed decision-making. Numerous reports have been published by various inter-governmental, governmental and non-governmental organizations to catalogue and assess alternatives to the ozone depleting substances, since the substances have been used in various technical sectors, like in refrigeration, air conditioning, flexible and rigid foam, fire protection, aerospace, electronics, agriculture, and laboratory measurements Under the Montreal Protocol on Substances that Deplete the Ozone
