Climate change - Ignore the man behind the curtain

TPP is a scientist, but a botanist not a climate scientist. Still it seems that some people want assurance from someone who speaks and reads science about scientific conclusions about climate change. What bothers this scientist the most about climate change is what is not being talked about, and that what is human population growth. In many places the rate of growth has slowed but in other places, mainly African & Middle East, the growth rate is unabated.  It's a simple equation, more people means more energy, more food, more water, more waste, more contributions to the things causing global warming. Even with our reduced rate of reproduction, the population of the USA will grow by 50% in the next 80 years. There are countries on Earth where that growth may be as high as 400%!!  This tends to make for a pessimistic attitude, where the potential movers and shakers act as if population growth were no matter at all.  A few people are daring to broach this topic, so whether this gets any traction or not will be seen. There have been so few people willing to act on population, willing to even acknowledge this if a problem, that should you bring it up legions of denialists will arise. It's as if all of human culture has been constructed as a huge population Ponzi scheme, such that without a constantly expanding base the whole pyramid would come tumbling down.  Sorry to bring this up what with so much cheerful news of late to buoy your spirits and optimism.  So to end with something positive alternative energy technologies are increasing in importance and getting more economically feasible and at a faster pace than anyone could have guessed. And it's a Monday.

Yes. We need an economic system that works with a shrinking (then steady)
population. There is no future for an economics that depends upon growth.
