How much should we curtail our production and enforce strict carbon emission, i.e., to what extent do we allow our concerns for global warming affect our GNP? Additionally, other countries, especially China (I know, I lived there) completely (well, not completely) ignore their pollution contribution? And because of this, was Trump correct to withdraw from The Paris Accord? And why can't we produce an equation that accurately will predict the continued warming effects?Account
