Global warming is a hoax. Greenhouse gases are mostly natural. Only three to four percent are man made. Greenhouse gases are mostly water vapor. If you remove the water vapor from the man made gases it goes down to half of a percent. So what will taxes and regulations do? Nothing on a global scale. Even if you stop all power plants, cars, planes and industry in America (all polution) thus destroying the economy and sending us back to the stone age it might equal one percent of total global greenhouse gases. Again no difference. Climate changes happened before and will continue to happen. Be more worried about the next mini ice age and save your taxes and regulation for real problems.
