@ND, if you are wrong? What happens? Should we stop insuring our homes because the natural cycles of the planet's climate are good?
Should we not be investing in alternative energy sources which are cleaner (less air pollution than coal/oil), renewable (ie they don't run out, at least until the sun does, but we've a few billion years on that count), and more opportunity for energy independence (ie you don't have to connect to a government run grid to get your energy if you can produce locally - in your house).
If people in need deserve help, why should the US not spend money saving lives abroad, investing in infrastructure, education, and healthcare for the poorest humans, so they can A) pay for their own needs in the future, B) contribute to the global economy, and C) return the favour if the US ever needs it?
Global warming: describes the increase in average temperature we've seen since the 70s. Long term trends don't lie, but while we have records going back to the 1880s, the measurements have gotten better since we've had satellites (so we could measure the whole globe with one sensor multiple times per day). We have to piece together all the other data, which is harder. That doesn't mean warming isn't happening.
Global cooling: the myth that in the 60s and 70s scientists were more worried about global cooling is based on lies. The fact was at the time many scientists were worried about cooling, and others were worried about warming. Over time they worked out the differences and came to a conclusion. But here you can see that there was still a larger number of papers published predicting warming: https://skepticalscience.com/graphics.php?g=43 .
Climate change: As the globe warms, on average, we will see more energy in the climate allowing for more extreme positions to be explored. This could mean freezing snow storms in may, or 'tropical' storms outside of the typical storm season or region... It better describes the effect or rising temperatures. Of course i'm talking about Human Cause Global Warming. Which is real and will have a devastating effect.
But i'm not talking about the US redistributing money to other countries. That is an agreement between countries, those who choose to make decisions based on the science. No climate scientist has been paid off by poor countries to help redistribute the US's wealth, the suggestion is ridiculous. If that is the outcome of international agreements, then so be it.
If the US refuses to join international agreements, then the international community should boycott US trade. It is a simple mechanism to reduce the US emissions by crippling her economy.
