Today I am only going to talk about one amazing video--with nothing but hard data on climate change for almost one million years. Produced by NOAA, it is a 3:44 silent video of a graph in motion--showing dynamic changes in the CO2 levels in our atmosphere at many places around the world.
Please watch this video. You won't have time to watch it within the 1-minute goal of this bite-size blog, so just be sure to watch it tonight or this weekend. You will always be able to find it on this 9-14-16 post on the BSB page of my hpjmh website.
Tips for Watching. Notice that the video begins in 1979 and runs through 2014. But it doesn't end there. That's when it begins to reveal the graph in reverse for the last 800,000 years. A few things to watch for:
Make sure you watch it until the end. It will stop for a few seconds before going backwards.
The red dot location is at Mauna Loa in Hawaii. Many other locations around the world are also shown as black, blue or gray dots.
Notice that the "busy" end of the "pump handle" is in the Northern Hemisphere, where most of the human pollution is taking place.
Notice the South Pole CO2 (blue dot at left end) rising steadily upwards with only slight variation.
The first part of the graph starts in 1979, when the CO2 concentration was 335 ppm. By 2014, many locations are reading over 400 ppm.
For a normal world, scientists agree that we need to stay below 350--but that train may have left the station.
The Bottom Line. The first step toward solving climate change is the awareness and acceptance that we have a serious problem on our hands--AND that we are causing the problem.
This video should be required viewing for every member of Congress. I first posted it on 12-15-15 in this full-size blog entitled:
