WND previously reported President Obama's science czar John Holdren was among the scientists who predicted 1 billion people would die in "carbon-dioxide induced" famines in a coming new ice age by 2020. Oh brother! THAT didn't take long.....
I just want to know (from the people who claim to know), does CO2 cause global warming or global cooling?
I thought that it helped plants to grow?
I dunno....
Without getting technical. Yes. Plant life requires CO2 to grow and maintain. The process of photosynthesis in plants require CO2 gas in order to create the sugars and some other things they need to stay healthy. Animals breath out CO2 as well as do plants. It is a harmless gas.
Can CO2 cause either warming or cooling within any of the layers of our atmosphere? Not to any extent where it can effect the over all temperature ranges of our atmosphere.
We must remember CO2 constitutes only 0.36 of 1 percent of the total gas mixtures. In short it is a trace gas.
Lab studies using instrumentation such as Infrared Spectroscopy can accurately measure at what frequencies C02 can absorb heat energy. Take my word for it, it is a very small amount of energy and the issue as how this energy can then somehow be transmitted into say water molecules just to name one part of the over all atmosphere is in constant debate.
But most studies on the subject show that C02 simply cannot contribute to any significant level of atmospheric warming that then somehow (non-technical remember), through what is called emissions. One can view papers by physicist and others that clearly show the thermodynamics (heat transfer mathematics), simply would not allow C02 to cause any form of global warming. Nor an opposite effect, global cooling.
In fact there are papers that I for one am trying to get peered reviewed that demonstrate the whole greenhouse effect is bad science to begin with. It gets very complicated.
But as many have been predicting we have been in a continued slow global cooling for many many years, with a short break of warming for about a ten year stretch that ended about ten years back, roughly.
The people who have pushed for global warming fudged the models used to predict climate changes, and we now know they also badly manipulated a lot of raw data that many of the models used to make it look like we where in a steady global warming trend.
Hope the above gives you a little snap shot into what has been going on. Here is one web site you can view to get an idea as to what has been going on
Climatedepot.com you may find it rather an interesting site.
There are other sites, but they indulge in more technical writings. If you want some. Ask me I will provide the URL to the sites.
