I have not driven a car to work in 6 years, ride a bike (recumbent trike) instead. We have 2 cars and four drivers in the house, with the cars being a Toyota and a Subaru. LED bulbs throughout the house. 1800 square foot house, minimal lawn but a lot of flowers and shrubs.
That being said, the Chicago area used to be covered by ice 2 miles thick. It melted, was gone for a long time, then reformed, and melted again. All this was before man had any impact. If climate change happens, I'm glad its warming and not cooling!
The glaciers I saw on the Ptarmigan traverse in the North Cascades of Washington are smaller now than then. I have pictures from 1973 of pretty decent sized glaciers, that now are much smaller.
IMHO, all environmental problems start with too much human population and too much habitat conversion to housing, roads, and agriculture. All proposed fixes don't do anything for population growth.
My personal soapbox: the sooner we run out of oil (in the world) the better. Gas will get more expensive, cars will get smaller, public transportation will get better. When I am elected King (president would not have enough power to do this) gas will never cost less than $4 a gallon. Every city will have its own nuclear power plant. Nevada will host hundreds or thousands of them. Every house will have solar panels. Golf courses will be taxed heavily on water usage. Cooper Minis will be the largest car on the road. But backpackers will be allowed to have a small SUV to get to the trailhead.
