Global Warming

Global Warming is a "hot" topic. This video looks at the evidence and focuses on these two questions; Is the Earth getting warmer? and What ARE the effects of Carbon Dioxide in the atmosphere? Check it out, the answers may surprise you.

Can I have the source of the music played background? Its played in Mechanisms of Evoltion too,,

@jhonnygilbert We have an audio technician on staff who creates our audio tracks. His primary source for the music is from a subscription we have with FirstCom. We do not maintain a music list for each video and we do not maintain a separate music file for each video.

The video completely ignores the shrinking ozone layer.

I had never seen a video explaining how such a small amount of CO2 could warm the whole atmosphere, so I made one. It’s an explanation for school kids, so even if you don’t get science, you should still find it very informative. Google "GW017 Air and CO2"

LOL Look who has a a bigoted closed mind now.

Yay global warming doesn't exist. Now we can stop worrying about pathetic arguments that state we are ruining our planet.. Because we're not. Even if humans wanted to deliberately change the climate I believe we would fail. The Earth's state of equilibrium is far too stable to be changed by humans. Everytime humans try to fight nature, nature always wins out

The pie chart concerning carbon is very contradictory. It argues that the carbon increase is insignificant, but then goes on to to say that it has had profound effects on plant life. ....So why can't it have incremental effects on temperature?

I would also question the percentage of the greenhouse effect it says is caused by human activity. Did it take into account the past few hundred years of deforestation? Did you know warming and pollutants effect cloud cover?

The videos low point is when it quotes various news articles from winter in the northern hemisphere in 2008. This is a very specific time and place and means nothing in the long term global trend. The bias is shown when the video neglects to mention the record highs that have been broken and rebroken recently.

It then reaches a "verdict" saying we don't need to worry. It is also a failing of logic to say "everything is alright because the increasing extremes haven't killed us yet."

The videos information on polar ice is about seasonal ice. It does not talk about the ancient ice, which is what climate scientists talk about, not this. Ice which has been permanent for hundreds, thousands or even tens of thousands of years is now melting.

Chart 4 says the correlation is unmistakable, and yet it states the solar output is falling while the temperature data it is correlating to is climbing.... this suggests there are unknown factors at work, and you can't draw any conclusion from it.

Chart 5 shows a drop in global temperature between 2007 and 2008. Year to year fluctuations are just microscopic bumps on a larger trend (the first chart), so are fairly meaningless.
