Here are some things that are fairly easy. 1) drive a more fuel efficient car. Not only do they emit less CO2, but they cost less to purchase and have lower fuel costs. 2) Do a little planning that can reduce short trips in the car. Sometimes if I forget something at the store, I just decide to do without that evening instead of making a second trip. 3) line dry your clothes on nice days. 4) Eat less meat. While I'm not a vegetarian, I do have several vegetarian recipes that I cook on a regular basis. 5) Buy local. I drink my locally brewed craft beer almost exclusively so that means almost not transportation costs. There are a few west coast brews that I love, but I rarely drink them because they have a big CO2 footprint in the transportation cost.
All of these things take a little more effort, but most actually save money for the average Joe trying to make ends meet.
I do all these things personally, and more, but I was speaking more in general terms for the climate change industry to appeal more directly to people with helpful ideas. Kind of little trickle up solutions instead of hammer down. Where I live most people drive small cars, and the public transit is packed. There is recycling every week, and the bins are well-used. Most people have switched to LED lights and other energy saving devices. When there is money to be saved, people will engage; that's one thing we all have in common.
What I am wary of is the grand schemes of politicians. People march in the streets with placards, but that does nothing but waste wood and cardboard and they use some form of motorized transport to get to these rallies in the first place. It's the same kind of waste as politicans chemtrailing their way to champagne conferences.
I guess there are two ways to look at it; individuals doing what they can, or people in power mandating things. I lean towards the former. I think that people and their free enterprise are always more effective than political beauracracies. I am not sure how places like China, India, and Africa are going to act, with the lion's share of humanity, and it is totally beyond the scope of my abilities or responsibilities to conceptualize it. I do not know whether the people or the politicians there are better suited to bring change, but I tend to think that local actions there too would be more effective than grand global or national strategies. I am still surprised that China is not mass producing electric cars by now.
The only role that I see for governments is to finance the construction of nuclear power plants and subsidize the research and development of electric vehicles. Nothing more. The people will work out the rest. The time for studying, and researching, and writing papers, and publishing charts, having conferences, and so on is over. Such a waste of time and money. All the CC academics, activists, and lobbyists should now move into the two aformentioned industries; enough talk.
Our prime minster writes cheques for billions of dollars and hands them to some global agency. Ridiculous. He should be giving the money to local electrical technology companies. One man, Elon Musk, is doing more to fight climate change that any government on Earth.There is a company based here call Bombardier. They make trains, subways, airplanes, etc. Surprised too that they have not got an electric car on the market. Give them 20 billion dollars and they'll get in done.
My faith in humanity is reserved, but my my faith in politicians in nil.
