b'CLIMATEClimate change, broadly interpreted, is a significant and lasting change in the weather patterns including average conditions or extreme weather events. CHANGEClimate change over the millennia has been caused by many factors including oceanic circulation, distribution of plants, variations in solar radiation NOWand volcanic activity. Most recently human emissions and land management have driven a build-up of the greenhouse effect causing rapid global warming, and climate changeANDCLIMATE SCIENCEINTOScience has been aware of the greenhouse effect and climate change since the early 19th century when ice ages and other natural changes in climate were THEidentified. Through the 1960s and 70s the evidence and scientific consensus that global warming was caused by increasing carbon dioxide gas both continued to grow.FUTURESince the 1980s, scientific research using computer models and observational work including multiple disciplines and has further expanded the detail of our understanding and its scientific consensus. Its complex and its an immenseThere is current scientific consensus approximately ninety-eight% support for a range of findings is that:challenge for future decades butSince the early 1900s the earths temperature what happens in this decade willhas been increasing but it has increased most dramatically since the mid 1970shave far reaching effects into theContinuing GHG emissions add to these temperature increases and adverse economic, next century. It is indeed the nextsocial and environmental impacts.Humankind can slow the pace of global few years that are critical to set us onwarming and its impacts by reducing their greenhouse gas emissions the narrow path to avoid the worstThe global mix of greenhouse gases come from a range of human activities including outcomes of climate change.Electricity and Heat-25%, Agriculture and clearing-25% Industry-20% transport- 14% and buildings-6.4% and other 10% The primary cause of this warming is from human greenhouse gas emissions (including carbon dioxide-76%, methane-16%, nitrous oxide-6% and CFCs-2%)Various gases impact on global warming differently and stay in the atmosphere for longer once released. Per unit of emissions. CO2 has a global warming potential of one, while methanes global warming potential is 25 time more and nitrous oxide is 300 time more. Different CFCs can produce up to a 10,000 times as much global warming as CO2.'
