What can keep the energy in the atmosphere? The answer is greenhouse gases. Science has known about the effect of certain gases for over a century. They ‘capture’ energy, and then emit it in random directions. The primary greenhouse gases – carbon dioxide (CO2), methane (CH4), water vapour, nitrous oxide and ozone – comprise around 1% of the air.

This tiny amount has a very powerful effect, keeping the planet 33°C (59.4°F) warmer than it would be without them. (The main components of the atmosphere – nitrogen and oxygen – are not greenhouse gases, because they are virtually unaffected by long-wave, or infrared, radiation). This is the second piece of evidence: a provable mechanism by which energy can be trapped in the atmosphere.

For our next piece of evidence, we must look at the amount of CO2 in the air. We know from bubbles of air trapped in ice cores that before the industrial revolution, the amount of CO2 in the air was approximately 280 parts per million (ppm). In June 2013, the NOAA Earth System Research Laboratory in Hawaii announced that, for the first time in thousands of years, the amount of CO2 in the air had gone up to 400ppm. information gives us the next piece of evidence; CO2 has increased by nearly 43% in the last 150 years.

It would be nice if someone actually did something about this crisis that has been understood for the past at least 40 years! Instead, we're moving in the exact opposite direction when it comes to carbonizing the atmosphere: the End of the Cold War and end of communism in the Soviet Union and China resulted in the global imposition of neoliberal capitalism on the entire world, through it's governing agencies-- WTO, IMF, and the World Bank, and other agencies of the Transnational Capitalist Class.

A quick example would be what's left of the rainforests in the Indonesian Archipelago: environmentalists keep demanding that no more forests be clear-cut for the growing of palm tree plantations for the production of more and more palm oil for global agribusiness, but guess what! Capitalism...through its international moneylending structures demands more forests be cut down to supply the growing, global palm oil market! Maybe they'll toss a few coins at the WWF to "save the Orangutans" or some other bullshit publicity gesture, but the net result is more wholesale destruction of natural ecosystems on a grand scale, while conservatives declare no such problem as climate change exists...as they fill their wallets with more cash/ while the liberal doogooder business leaders declare they're going to do something about the problem and then DO NOTHING of substance....as they also fill their wallets!

End result: we're ALL dead....including the billionaires unless the entire global hegemonic economic system is scrapped and rebuilt from the bottom up with localized economies.
