Hey Leo, did you know that there’s this invisible ring around the planet, Earth? Let’s talk about this ring around the planet. It has a name. It is called Greenhouse Effect. See, this magical ring contains water vapor, carbon dioxide and methane. This ring acts like a Venus Fly Trap that traps heat instead of flies. See, the heat from the sun would bounce right off the earth (and we would turn into icicles), but the Greenhouse Effect traps the heat that radiates from the earth (so we are kept toasty!)
Now if the concentration of these gases in this ring were too low, we would get too cold, but if they were too high, we would get too warm. As you know, we are being told that they are too high, and we are getting too warm. This is mainly blamed on carbon dioxide (which we exhale with equal proportions of water vapor, but which we also produce by combustion of anything we burn.) It is logical then, right?
Well, from 1880 to 1978 the data collected are ground temperatures of the earth. Say, do you think they may have been forgetting something? What is the water percentage of our planet, Earth? That’s right, Leo! Around 70%! Now, data from NASA satellites measure 100% of the earth, not just 30%. From 1979 to present, we are getting NASA data that are more accurate. What does this data tell us?
Overall, from 1880 to 2000 (taking in both data,) we have seen an average temperature change of 1.6 degrees Celsius or 2.88 degrees Fahrenheit. Is that significant? When I say significant, I’m referring to temperatures which exceed 35 degrees Fahrenheit. Is this because of humans?
A Harvard study done of over 240 studies on “global temperatures in the past” found that the earth was SIGNIFICANTLY warmer in the 9th and 14th centuries. Interestingly, this was BEFORE the Industrial Revolution (must’ve been those pesky ancient aliens and their spaceships!)
What about the Larsen B ice shelf melting in the Antarctic Peninsula? Glad you brought that up, Leo. What about the west Antarctic ice sheet that has been thickening? Interestingly, the Antarctic, overall, has been cooling since the 60’s. We know this from observing the global data as opposed to the ground data.
Now, do me a favor, Leo, and quit your job as Obama’s water boy. I believe your true master has a very good handle on the checks and balances of this planet, Earth.
PS~ I enjoyed our tender moment. I’m glad to have been your favourite teacher.
