Featured review
Start planting trees please. Check out ecosia.org
An important climate change episode that provides an easy to understand graphical illustration of how much C02 humans are emitting globally. They suggest imagining digging up 10 billion tons of coal per year and setting in on fire. That is essentially what humans are doing. Who in their right mind or not brainwashed by big energy corporation propaganda could possibly think that will not significantly affect ecosystems and climate globally? They tell us that humans currently emit about 37 billion tons of C02 globally and that must be reduced to 0. But that is not the end of the problem. There is still over 600 billion tons of C02 emitted from the beginning of the industrial revolution still lingering in the atmosphere and warming the planet via the greenhouse effect. Nothing major about that can possibly be done anytime within the next 15-20 years and it will still be highly debatable then. There will not be one solution but many. This episode covers some of those briefly including carbon capture; carbon recycling; cloud seeding to cool regions or the entire planet; and probably the simplest and best idea, planting a trillion trees. The later could capture 200 billion tons of carbon. They show how new advanced mapping technologies using laser and 3D imaging can better measure forests and land, revealing that the planet has room to plant 1.2 trillion trees. The downside is that food demand will increase significantly over the next 30 years, so do we create another problem by restricting land for trees. Not necessarily because we can also grow crops more efficiently and in ways that captures more carbon.
Also, let me dispel some of the misinformation in other "reviews" here. A basic definition of climate is "the weather conditions prevailing in an area in general or over a long period". So when people say "the climate always changes" it is clear they do not know the basic definition. Yes, climates can change but they may not do so for millions of years. We are seeing climate change now in the geological blink of eye.
No, volcanoes do no emit far more C02 than humans. That is ignorant. I know it can be hard to imagine, but just look at any gigantic open-pit mine of anything dug up by humans. Multiply that by 1000's. Or just use the illustration of gigaton coal blocks from this show, and then it is not so difficult to see how drastically humans are altering the Earth, much more than volcanoes.
For the 10 billionth time people, what is most relevant is the rate of change. Just about NEVER has the Earth warmed this fast. Furthermore, there has been enough data to statistically link the increase in temperatures to human C02 emissions. Stop with the pathetic and vague "climates always change" cries please. Nothing happens without some cause! If it is not C02 then what is it? All the other explanations deniers have tried like sun activity have been proven not to be the cause. In fact, solar activity is at a low, so that cannot possibly be the cause of warming.
