Are we really responsible for global warming?

Question

I Mean think about it!! billions of ppl coughing and exhaling Carbon dioxide, cigar,cigarrette, smoke. Farting

Pig and Cow farms reeking of crap (Methane)

Stop blaming the industries and vehicles!!!!

Answer 1

Plants take CO2 out of the air as they grow. They release the O and keep the C. A year later people eat the plant and also breathe out CO2. The O in that exhaled CO2 came from the air and the C came from the plants eaten, which got it from the CO2 in the air. So people are not adding CO2 to the air, they are just recycling it after a year or so. Same with all living things. But when people dig coal out of the ground and burn it, that releases carbon dioxide into the air that did not get removed from the air last year. It is carbon that has been buried for millions of years. That is the problem!

Answer 2

I know it's not politically correct, but I think the jury is still out (if the present CO2 levels that we have increased over the last century are raising average temperatures). The whole atmosphere and how it interacts is just too chaotic and dynamic to get a handle on and model, look at our miserable attempts at weather forecasting. And besides, long term we are headed into an ice age. So perhaps some additional CO2 is a good thing long term...? But common sense; adding more and more sequestered CO2 and then just not worrying about the consequences? That's just dumb.

"Look and make up your own mind"...then he links to a tirade against the global warming consensus, instead of to data.

"Recent research shows that human activities have lifted the boundary of Earth's lower atmosphere. Known as the troposphere (from the Greek tropos, which means "turning"), this lowest layer of the atmosphere contains Earth's weather. The stable layer above is called the stratosphere. The boundary that separates the two layers, the tropopause, is as high as nine miles above the equator and as low as five miles above the poles. In an astounding development, a 2003 study showed that this tropopause has shifted upward over the last two decades by more than 900 feet. [10] The rising tropopause marks another human fingerprint on Earth's climate.

"In their search for clues, scientists compared two natural drivers of climate (solar changes and volcanic aerosols) and three human drivers of climate (heat-trapping emissions, aerosol pollution, and ozone depletion), altering these one at a time in their sophisticated models. Changes in the sun during the twentieth century have warmed both the troposphere and stratosphere. But human activities have increased heat-trapping emissions and decreased stratospheric ozone. This has led to the troposphere warming more because the increase in heat-trapping emissions is trapping more of Earth's outgoing heat. The stratosphere has cooled more because there is less ozone to absorb incoming sunlight to heat up the stratosphere. Both these effects combine to shift the boundary upward. Over the period 1979-1999, a study shows that human-induced changes in heat-trapping emissions and ozone account for more than 80 percent of the rise in tropopause height. [10] This is yet another example of how science detectives are quantifying the impact of human activities on climate."

The Canada Free Press article, by contrast, offers this for evidence: "These climate changes are well within natural variability and explained quite easily by changes in the sun."
