And by every measure, we are losing food production capability. Fish stocks are dropping. We've lost 50% of fertile soils in 50 years. Population control is very important and an increase of 4 billion is not inevitable--merely probable. There's a difference. But, what matters most is not how many people are on the planet, but how much each person consumes. 11 billion living like Americans would wipe-out Earth's resources in a matter of months. Rosling's rosy future is a fantasy. He was in denial. Paul Ehrlich had a better handle on reality, even if his projections were not perfect.

Certainly his presentation is excellent, but one thing stuck out to me: the claim that the leading cause of death in adolescent girls is suicide followed by linking that to limits placed on their education. A small amount of googling leads me to several sites that claim suicide is also a leading cause of death for adolescent boys, but no-one would swallow a throw-away claim that this is caused by limiting their education, but a moment's thought might lead you to wonder. Someone once said that there are lies, damned lies, and statistics. A slick presentation ought to make one all the more suspicious.Tim Abbotthttps://www.blogger.com/profile/15545748728442623013noreply@blogger.comtag:blogger.com,1999:blog-4912713243046142041.post-49999556877171297392015-03-13T19:37:46.828-05:002015-03-13T19:37:46.828-05:00So, 33% increase of a potent greenhouse gas in the...So, 33% increase of a potent greenhouse gas in the atmosphere over a 100 year time period, by your own estimation.

Maybe educating someone isn't possible without offending or embarrassing, which is why media rather confirm our preconceived notions rather than actually inform and educate us.

The underlying principles of interaction between gas and (heat) IR radiation is straight up quantum mechanics. CO2 because of this molecules geometry happens to absorb various frequency bands of infrared. Now water vapor is somewhat similarly shaped and also absorbs a lot of heat, but unlike CO2 it actually eliminated from the atmosphere as rain, snow or dew, as soon as the concentration reaches a certain level, whereas CO2 isn't eliminated by weather it can only be absorbed by plants.<br />You might say that CO2 concentration is still really small compared to H2O in air, which can reach up to 5% in a very hot and humid climate, but the same isn't true for the atmosphere at large which is generally too cold for water, clouds don't get that high up where it's cold. <br /><br />Water has a percentage in air that is fixed and rather small, but it completely makes weather, climate, life etc. Small percentage - big importance. The percentage is fixed by an equilibrium. CO2 or other greenhouse gases aren't affected by temperature as much as water is. <br />If only we could make it rain dry ice, charcoal or limestone, our climate troubles would be over.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-4912713243046142041.post-84629436519750624772015-03-10T20:38:15.016-05:002015-03-10T20:38:15.016-05:00I am big BIG Rosling fan.

If not BY him, then by someone using the same facts. <br /><br />And where does he get his facts?<br /><br />All of his facts on his Gapminder graphs (free download) are from the official statistics of each country. He isn't inventing any of it. He is only presenting what is real.<br /><br />The amazing things he points out are the vast increase in life expectancy and the great drop in births per woman. Mexico has a birth rate nearly as low as the USA. Even with the Catholic church's huge influence in Mexico (the world's most Catholic nation in simple numbers). But women in Mexico discovered the Pill a long time ago, and they have basically been telling the Pope to shove it, because they can SEE the benefits of smaller families. And it is not just Mexico, not at all.<br /><br />What Rosling does by giving us the REAL facts is to allow us all to actually think the world is getting more sane, and that some of the big problems ARE being solved. We are given some hope that the world ISN'T going to hell in a handbasket.<br /><br />(Sorry for the editorial, but...) Now we only need to get people to learn about their misconceptions regarding global warming, which is happening at a much smaller rate than the headlines would have us believe and which is NOT solely due to CO2. The warming we have seen is from a multitude of factors - the "urban heat island effect" skewing the temperature averages, climate variability that is begin recognized as cyclical, and the world coming out of the Little Ice Age which ended in about 1820. Yes, the world warms as it comes out of cold periods; no DUH. And the further we get out of that cold period, the warmer the planet; it doesn't take rocket scientists to see that. CO2 is a very minor player.<br /><br />A quick quiz (don't peek below) - What percentage of the atmosphere is CO2?<br />A. 14%<br />B. 4%<br />C. 1%<br />D. 0.4%<br />E. 0.04%<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />.<br />The answer is E, 0.04%. <br /><br />400 parts per million.<br /><br />99.96% of the atmosphere is NOT CO2.<br /><br />In 1900 the answer was about 0.03%.<br /><br />At that time 99.97% of the atmosphere was NOT CO2.<br /><br />So the non-CO2 portion of the atmosphere has changed from 99.97% to 99.96%. Can any of us tell the difference?SteveGinGTOhttps://www.blogger.com/profile/00697382976006839418noreply@blogger.comtag:blogger.com,1999:blog-4912713243046142041.post-61699988619315063592015-03-10T15:37:56.969-05:002015-03-10T15:37:56.969-05:00This was the best thing I've seen in a few wee...This was the best thing I've seen in a few weeks! <br />Thanks for sharing and for smashing some of my ignorant misconceptions!kaynoreply@blogger.comtag:blogger.com,1999:blog-4912713243046142041.post-18531699520690916392015-03-09T19:18:45.060-05:002015-03-09T19:18:45.060-05:00He really is an amazing lecturer.
