Am I not getting something on Climate Change?
Back in the 1960's when I was eight years old in 3rd grade elementary school, we took a field trip in a big 50 people buss with a bathroom in the back. Thank God it had a bathroom as it was like a 6 hour trip from Riverside California to the Giant Sequoias Kings Canyon National Park. All the kids were excited as we went around turn after turn on a very winding road ascending to the giants. Our main stop was a ranger station visitor center in the center of the Park - read my answer to the rest..

The biosphere is not a closed loop. It is an open system. Volcanoes and other natural sources have been adding CO2 to the atmosphere for many millions of years which plants and animals have been sequestering as coal, peat, soil, oil, shells etc in order to maintain a balance. The amount of carbon in all of these places is far more than the amount currently in the atmosphere. We are now releasing these stores of carbon at a far higher rate than they were laid down.
The amount of coal produced each year is about 8 billion metric tons and there is at least 100 years worth of coal in the ground at this production rate making 800 billion T. If we burnt all of this coal we would add about 60% to the carbon dioxide in the atmosphere not to mention everything else we are doing. Not all of this CO2 stays in the atmosphere but even so we are experiencing about a 2.75 ppm rise per year which means that the current value of just over 400 ppm could be close to 700 ppm in 100 years time if nothing changes.
It's easy to make calculations and warnings but trying to make the changes to even slow down climate change is extraordinarily difficult.

By the time we KNOW the answers we will all be dead and our grandchildren will be the ones who will have to deal with it. But the amount of CO2 from Vesuvius is small compared to our production year in and year out. Everything from either side is a prediction. Yet we are quite safe. So doing nothing means we do not have to face any consequences. Doing something means we have to pay a price now. Naturally we would all prefer to NOT pay any price now. If we are wrong in this then we will be cursed by our descendants. By then it will be too late to make a change. What then is the RIGHT thing to do now?

In the center of the visitors center was a full size slice of the trunk -maybe 20ft in diameter- of a Sequoia that had to be cut down for safety reasons,(about to fall they said) they loved to show the visitors the 2400+ growth rings as this was a very old tree. Some growth rings were wider than others and after the park ranger pointed to an area of rings and said this is the year 1 A.D. when Christ died and a 3rd grader blurted out "Did you have to count all those rings to find that out?" Now the next thing to come out of the mouth of the ranger would stick with me, probably for the rest of my life. The ranger smiled and said "we did at first until we kept noticing this area just around 80 A.D. has a dozen or so of the widest growth rings of any where on all the Sequoias that had to be cut down". "Whats going on here?" the ranger asked us? Now with dead silence as nobody knows, our teacher with a big smile blurts out "Mt Vesuvius" she knows her history. The ranger agrees and while none of us 3rd graders knows what Vesuvius is we most certainly will after our teacher turns it into learning experience over the next week. Mt Vesuvius spewed so much carbon dioxide straight up into the atmosphere at such a rate that it displaced all the air in a 5+ mile radius at the base with super heated carbon dioxide gas turning humans and pets to carbon statues instantly in the town of Pompeii 5 miles from the spew hole. Why the wider growth rings in the years just after the eruption? Carbon dioxide is a greenhouse gas that makes for warmer growing season and the extra CO2 also increases the growth rate thus the best growing conditions for trees. So what happened to all the extra CO2? The fossils of plankton in a sedimentary rock quarry with yearly sedimentary rings of it own- ocean water laid down an annual fossil record has both fossils of CO2 consuming and O2 consuming plankton's. Normal proportions of the plankton changed to grab up all the CO2 and return the earth atmosphere to equilibrium in just a couple decades. Today with the proportions of plankton changing in a chase to keep up with more and more green house gasses we may see an Ice Age soon if we don't keep a head of the plankton. So if you look at ice core data and don't find the extra CO2 in the decade from 80 A.D. should you believe its good data?

No one can deny the recorded temperatures of Global Warming, but the debate is whether to panic, and how much is caused by gasoline engines.

The sun makes things grow. Like trees and food.
Worldwide increases include food production, trees, polar bears, etc.
1. "Contrary to the prevailing view that forest area has declined globally—tree cover has increased by 2.24 million km2 since1982." (Nature). See chart below
2. "Food production has increased 25 percent since the year 2000." (UN-FAO)
3. "Polar Bears numbers are dramatically up since the 1960s." (Zoologist Dr Susan Crockford)

Yes, first day of spring was 84F here. Must be some natural cycle thing, even though it can be explained by greenhouse gas emissions. 🤔 I'll trust my loud mouth conservative friends, their angry arguments and cherry picked observations must be right. Right wing nonsense, that is.
