Climate change leads to significant economic and ecological implications and it has accelerated dramatically in the last 50 years. Data from NASA show that Carbon Dioxide in the atmosphere today is at 405.25 ppm, the highest it has been in 400,000 years, and 50% of that increase has occurred since 1950. The ten warmest years in the 136-year temperature record have all occurred since 2000, with the exception of 1998. And, 2015 and 2016 are the two warmest years on record. Ever. The arctic sea ice is declining at a rate of 13.3% per decade, much faster than it was between 1980-2000, and the major land ice masses are shrinking at the pace of between 134-281 gigtonnes per year, with the pace radically speeding since 2000. NASA, and others, conducted multiple studies demonstrating that this warming is not due to changes in the Sun’s activity or temperature. The Intergovernmental Panel on Climate Change (1,300 independent scientific experts from countries all over the world) state that there’s a more than 95% probability that human activities over the past 50 years have warmed our planet. The human population has gone from less than three-billion people to more than seven-billion since 1950, radically increasing human-produced greenhouse gases (with carbon dioxide, methane and nitrous oxide increasing by 70% between 1970 and 2004), which in turn caused much of the observed increase in Earth’s temperatures over the past 50 years.
