I still think my sister has figured it out. Cement!
More and more land is being replaced with cement, construction, roads buildings, parking lots. And when that natural land of dirt and grass is paved over with cement, thus the obvious takes place. Less natural grass land to absorb water and to give off evaporation. The natural ebb and flow is interrupted and the climate definitely affected.
Add to this the fact that cement holds heat and then gives off heat like a furnace. That absorption of heat from the sun then radiating that heat back into the atmosphere definitely warms up the atmosphere. Dirt and grass does not absorb heat like does cement, and grassland does not radiate heat back into the atmosphere like does cement.
People.... right there is the most plausible answer to climate change and increased seasonal temperatures. And, responsible for screwing up the weather patterns world-wide. You gotta admit it folks, what is happening is not good, not normal, and not typical to any other time in human history. And I do not see any way in hell to stop this trend or to reversed this trend no matter how much money we toss at climate change efforts.
To save the planet, we would have to stop building and expanding, then we would need to tear up acres and acres of pavement, and then replace that pavement with dirt and grass just as it was before. I don't see that ever happening. It will never happen.
And as we build and cement more and more this will only get worse Much worse.
Ok... a little fun game we can play.... Just imagine if you will.
Just imagine if you will a planet like the earth paved entirely with cement. What would you expect the climate of that planet to be like? Maybe that of Mars? Or that of Venus? Pluto? Well here's a shocker... that cement earth we imagine would never and could never support LIFE.
And THIS is our future.
