I'm sorry everyone, but I find the extent of climate change deniers and minimizers on this forum to beyond belief. Human caused global warming due in part to CO2 emissions is science fact. The more CO2 the more the warming. period - accept it!
HOWEVER - there are many many questions also:
- How much warming for how much CO2 (we have models, but models have uncertainty)
- What will be the exact effect of how much warming on different parts of the earth
- What is the true cost of that warming (both monetary - for example building coastal defenses - and non-monetary - for example how much is a forest worth?)
- To what extent do contrails reduce warming?
I believe the environmental movement has done a disservice to society by fear mongering and doomsday scenarios.To me their hard line is part of the reason for the push-back against needed changes. Pushing an environmental agenda others with a big stick is wrong. Maybe many here have a hard time accepting climate change due to legitimate career fears?
There are changes aviation can make. Bio-fuels from algae ponds in the Sahara is one interesting option among many. If people were to work together there would be no threat to aviation from the need to reduce CO2 emissions. To me it is hard to work together when many in the environmental movement are so hard line and unwilling to understand the social costs of their demands. People need good stable jobs and many in the environmental movement project a position that they care more for a single tree or owl than the children of those who earn a living in CO2 producing industries.
The real problem is not the science of climate change or the ability for tech to find solutions, the real problem is people can not compromise to a solution that works for everyone.
