Volcanoes ARE Cooling Earth

Volcanoes ARE cooling Earth: Aerosols from small eruptions have reduced global temperatures and tropical rainfall

• Volcanoes may have cooled the Earth by 0.05°C to 0.12°C since 2000
• Scientists had overlooked the role of aerosols from small eruptions
• The aerosols accumulate between the stratosphere and troposphere 
• This layer of the atmosphere is difficult to study as clouds obscure it
• Eruptions through 1990s and 2000s have contributed to warming 'pause'
• Global temperatures plateaued since 1998 after rapid warming in 1990s
• The findings mean models predicting climate change need to be revised
