  1. Three most important things you can do:
    – Eat less meat
    – Consume less (ex. don't switch iPhones every year because the new model has some minor upgrades)
    – Recycle and spread the mentioned information

  2. Where are the facts? "Can be" and "consequences" – do not mean anything, if the assumption is not proofed, that CO2 causees global warming. Unless this is done, this video is nothing more than propaganda.

  3. While you're at it, challenge the system of Capitalism which gorges itself on consumption and is the dominant form of pollution production. However, this would require getting together with other communities and protesting with solidarity.

  4. Warmest on record. We've only been recording weather accurately since 1880. So what about before then? Nat Geo, you should get a real scientist to talk about these issues. Not a mechanical engineer who an entire generation is going to automatically believe just because he taught them elementary science from a Zenith television when they were children.

  5. What about the snow in the desert we have had and all the cold weather we are currently getting in Europe and America…

  6. I hate all these people that talk about "overwhelming" consensus. Back in Copernicus's time, there was a "Scientific consensus" that the earth was the center of the universe. Did it make their model anymore correct? No, it didn't. Yes, its good to have scientific consensus, but if that's the only thing you can use to back up your statement, then it only turns into a club; a useless one at that.

  7. Pure propaganda. CO2 only comprises 0.04% of the atmosphere and has a specific gravity that is heavier than oxygen and nitrogen so its impossible for it to rise in the atmosphere. End of discussion.

    For several years the amount of pollution and Co2 being put into the air is increasing everyday. This creates global warming. Global warming causes wildfires, water rises, and an increase of heat. It is our fault for fueling this with pollution, deforestation, and our lack of trying to change the situation. Global warming has significant effects on the health of the planet and us as a species.

    To start this off, forests are affected by global warming in reason of more pollution, means more heat from global warming, meaning less rain, equalling to dry forests waiting for destruction. In an article called “Is Global Warming Fueling Increased Wildfire Risks?” it states “As the climate warms, moisture and precipitation levels are changing, with wet areas becoming wetter and dry areas becoming direr They also said “…hot, dry conditions also increase the likelihood that, once wildfires are started by lightning strikes or human error, they will be more intense and long-burning.”. This shows how global warming sets up forests like matches ready to be ignited by us, or naturally.This shows that global warming is causing dryness in the air, and that is a key element to fire. To add on, deforestation and wildfires means less trees to balance Co2 for less global warming, and wildfires are mostly caused naturally or by us.

    Not only that but also, due to global warming the polar ice caps are melting and causing waters to rise and flood areas. In an article called “Are the Effects of Global Warming Really That Bad?” states “The polar regions are particularly vulnerable to a warming atmosphere”…”This not only has grave consequences for the regions, people, wildlife, and plants; its most serious impact may be on rising sea levels. By 2100, it’s estimated our oceans will be one to four feet higher, threatening coastal systems and low-lying areas,” This shows that hat is an enemy to ice. The higher we let global warming to do this, beaches will overflow land area causing people to go the hills andhigher land. To add on, when the water rises, we have less land to live on like places in California, San Francisco, Japan or “other close to the beach” areas.

    Although this may be true, others think global warming is a myth or a debatable subject not yet proved. To a website called “friends of science” it states “Carbon dioxide levels have indeed changed for various reasons, humans and otherwise, just as they thought geological time…However, there is no proof that Co2 is the main driver of global warming.” They also said “There is no scientific evidence whatsoever that supports such claims on a global scale. Regional variations may occur.” This shows how people may have thought global warming isn’t real, and maybe said we “don’t have evidence” because people haven’t seen real problems yet. These people believe it’s not global, as in some places because they think its in some places instead of a global scale, however if they keep believing that until something bad happens it might be too late to fix this.

    The increased activity on pollution being put into the air causes disasters such as wildfires, water rises and heat. We fuel this with deforestation, smoking and pollution. Global warming is on of our significant effects in health of us and our planet.

  9. I'm gonna eat more beef. I love warmer climates, hope to have palm trees instead of snow where I currently live.

  10. I can't take him seriously when he is using ancient impractical units like imperial.
    Grow up idiot and use metric.

  11. "slight changes" in the earth's history? i think there have been some pretty major climatological changes in the past.
