This is the seventh blog in our climate college series, focusing on the relationship between internal feedback mechanisms and climate change. Arctic ice cover, water vapour and also the release of methane from the melting of frozen tundra all have an impact on the rate of global climate change. Is there a ‘safe’ upper level of global warming suggested by scientists and what is the ‘tipping’ point?
Scientists began considering that carbon dioxide from fossil fuels might impact on climate as far back as the 1800s and since the mid 1900s research provided proof that carbon dioxide in the atmosphere was gradually increasing. This tutorial provides a very brief history of the key steps and individuals who put the climate change puzzle together.
