Doesn't the world's enviroment constantly change. Most
of it froze over at one point. Did the dinsaurs cause
global warming then to unfreeze the ice age?? Or did they
cause it in the first place.
Maybe they used to much areosol??
Funny. :)
From what I have read, the planet *is* warming on it's own, but the natural timeline involves millenia instead of decades.
We are just putting a fast forward on certain aspects of this, which has it's own issues.
IMO, corporations and greed are the root cause and the largest obstacle to why we haven't implemented more efficient fuels for our vehicles, heating, and power generation.
I have a good friend who owns an HVAC company, and his industry experts have been marketing equipment upgrades based on warnings for many years about natural gas and propane price spikes... and recently we have been getting them.
There are a lot of people who think that the price increases on gasoline, diesel, nat. gas, propane, etc. are not even close to peaking.
George Bush installed a geothermal heating and cooling system at his ranch in TX that uses the stable temp of the earth (in the 5-50 ft below surface) which is then only *supplemented* by traditional fuels to achieve the desired temperatures in the home.
Total fuel/electricity usage is like 1/4 of traditional high-efficiency HVAC systems and central air conditioning.
What does he know that we may not??
Solar, wind, and geothermal are very easy to implement, yet there is resistance and negative spin when these are mentioned... where does that come from?? My bet is that the corporations who have billions (to trillions) invested in the rights for oil drilling/nat. gas, and mine coal... They have a *pretty strong* lobby...
My community just built a new jail/police building, and they looked into geothermal. A *study* concluded that the geothermal was not practical and that the traditional systems would be a better solution. The study got into the hands of some of the country's experts on geothermal who all said that the study's findings were all based on incorrect assumptions and flat out misleading data.
Who were the experts involved in that study?? Probably utility company cronies.
