Document Summary
The anthroscene large geographic eras, anthro humans. Human impacy marks the natural world, defining feature. Climate change starts with rising co2 in the atmosphere. We are at 400 ppm co2, we need to be at 300 ppm. 2nd half of 20th century where we see the growth. 1950"s marked the years where co2 emissions skyrocketed. Glaciers and ice are melting in the poles. Sea levels are rising, already having an impact on islands and coastal areas. The oceans are heating up more drastically then the land. Co2 levels go up, ph level goes up => water becomes more acidic. Co2 levels - 405. 1 parts per million (ppm) in 2016. Unprecedented in the conservatorys 59 year record. Rate of co2 growth over the last decade is 100 to 200x more faster than what the earth experienced during the transition from the ice age. Alberta has the most greenhouse gas emissions, on is a close second.
