A freind of mine states anthropogenic CO2 emissions have no affect on global warming. I disagree?

Question

Can anyone supply the scientific facts and evidence that anthropogenic CO2 emmisions have an affect on global warming ?

I disagree with him....I can't seem to remove the "?"

Answer 1

Researchers have recovered a nearly two-mile-long cylinder of ice from eastern Antarctica that contains a record of atmospheric concentrations of carbon dioxide (CO2) and methane--two potent and ubiquitous greenhouse gases--spanning the last two glacial periods. Analysis of this core shows that current atmospheric concentrations of CO2--380 parts per million (ppm)--are 27 percent higher than the highest levels found in the last 650,000 years.

and what do they say?? an ice age comes every 11,000 years approximately? how many ice ages are in 650,00 years??

Concentrations of CO of 800 parts per million (ppm) can be lethal after three hours.


First of all, the results demonstrate clearly that the relationship between climate and CO2

Comparison of CO2 emissions from volcanoes vs. human activities.
Scientists have calculated that volcanoes emit between about 130-230 million tonnes (145-255 million tons) of CO2 into the atmosphere every year (Gerlach, 1999, 1992). This estimate includes both subaerial and submarine volcanoes, about in equal amounts. Emissions of CO2 by human activities, including fossil fuel burning, cement production, and gas flaring, amount to about 22 billion tonnes per year (24 billion tons) [ ( Marland, et al., 1998) . Human activities release more than 150 times the amount of CO2 emitted by volcanoes--the equivalent of nearly 17,000 additional volcanoes like Kilauea (Kilauea emits about 13.2 million tonnes/year)!

assume that he is lying on everything he says, and research the claims yourself.
you'll find his only real mistatements, are:
1) implying that Lincoln freed the slaves based on moral obligation.

2) trying to predict how long it will be before we face consequences is quite impossible. the problems could come soon, or they could come a cnetury from now. it is pretty impossible to predict.

and
3) the CO2 concentrations will probably get us before global warming will.

Answer 2

Present-day carbon dioxide (CO2) emissions from subaerial and submarine volcanoes are uncertain at the present time. Gerlach (1991) estimated a total global release of 3-4 x 10E12 mol/yr from volcanoes. This is a conservative estimate. Man-made (anthropogenic) CO2 emissions overwhelm this estimate by at least 150 times.

Answer 3

The CO2 is absorbed by plants. Plants have recycled our air for millions of years. Look up photosynthesis on the net . The plants make there food out of the C in CO2 and the O2 is returned to us. That is also why the CO2 level is a small fraction of what you should expect to find. If it was not for the plants we would all be dead.

Answer 4

According to the CMIP5 climate model the rate of fossil fuel emissions should have a measurable impact on surface temperature about a decade down the line (See Ricke and Caldeira, "Maximum warming occurs about one decade after carbon dioxide emissions", Environmental Research Letters, December 2014). However, there is no empirical evidence of this effect in the data for the period 1850-2014. Please see

Answer 5

politicians like glenn beck do no longer think of it exists you recognize. through fact the scientist's have hidden schedule to get greater money for grant's and to take yet another step we'd certainly shop drilling on the sea floor through fact it is so secure and we've been assured via many conservatives christians that the earth would be re regulated via bypass son do no longer difficulty approximately it and that i'm particular europe isn't freezing now and that i will possibly get deleted for question answer format even nonetheless it relatively is the reality
