Is there proof that CO2 causes warming?
If so, please provide a link to said proof.

It doesnt help plant growth. Why do some hate plants?

Yes its been proven by our resident scientific atmospheric expert bmy! He can give you a link to Newsweek if you would like or Vox!

Nope.

I know what does cause warming. Heat from the sun.

Al Gore said so



Duh....

There’s a lot of correlation in the ice core data, and CO2 does have the ability to trap sunlight more so than oxygen and nitrogen. However, it has not been proven to be the causative factor of warming, and anyone who tells you otherwise doesn’t know their arse from a hole in the ground.

I need a study on this. Appeal to authority is more conclusive than observation with your own eyes.

Observation of direct increase in surface temperature attributable to CO2

quote:

Here we present observationally based evidence of clear-sky CO2 surface radiative forcing that is directly attributable to the increase, between 2000 and 2010, of 22 parts per million atmospheric CO2. The time series of this forcing at the two locations—the Southern Great Plains and the North Slope of Alaska—are derived from Atmospheric Emitted Radiance Interferometer spectra3 together with ancillary measurements and thoroughly corroborated radiative transfer calculations4. The time series both show statistically significant trends of 0.2 W m-2 per decade (with respective uncertainties of ±0.06 W m-2 per decade and ±0.07 W m-2 per decade) and have seasonal ranges of 0.1–0.2 W m-2. This is approximately ten per cent of the trend in downwelling longwave radiation5,6,7. These results confirm theoretical predictions of the atmospheric greenhouse effect due to anthropogenic emissions, and provide empirical evidence of how rising CO2 levels, mediated by temporal variations due to photosynthesis and respiration, are affecting the surface energy balance.


Always happy to show you evidence that you're wrong.

Define "trap" in terms of W/sec-m^2. Without units the term "trap" is meaningless.

Of course. We know that our Earth is kept warm by greenhouse gases, and that CO2 is a greenhouse gas. An increase in any greenhouse gas will cause an increase in warming. The only debate is by how much.

Since you asked for a link, here is the first one that Google gave me: LINK

I'd like to know when higher co2 levels have ever been bad for life overall on Earth.

How does that ability compare to water vapor and methane?

Probably never since the biosphere has done a pretty good job keeping up with what is released naturally.

Now, take all that work the biosphere has stored over the millions of years and release it at once, while at the same time reducing the cleansing capacity of the Biosphere.

Could that be a problem over time? Sure. It will probably put more pressure on the oceans to absorb that CO2.

Well, the greenhouse effect is caused by water vapor. We should ban water.

At a C02 concentration level of 400 part per million the total radiative forcing is 259.01 W/m^2.

According to this:

the radiative forcing from 378 ppm of CO2 to 440 ppm is 0.24 W/m^2.

Interesting that my calculations are consistent with the observed calculations in the study you linked.

0.2 versus 0.24...pretty close.


But relative to the total of almost 260 W/m^2 that is tiny...really tiny contribution.

People are causing global warming. You can’t deny this. Just look at the overall world population. In roughly 1804 is when the world population hit 1 billion. It took 123 years (1927) to hit 2 billion. Then just 33 years to hit 3 billion, 14 years to hit 4 billion, 13 years to hit 5 billion, 12 years to hit 6 billion, and 10 years to hit 7 billion.

Why does this matter? People exhale CO2. So the more people on the planet the more O2 is used and CO2 produced. To stop global warming we need population control.

I suggest we start by aborting all liberal babies so no more liberals are born. I see it as a win win. We stop global warming (liberals are happy) and we kill unborn babies (liberals are happy). The conservatives will be happy once all the liberals are gone.

The Climate Change believers are not really interested in "life overall". It is primarily the humans they are trying to save.

And we should ban R12 freon, it depletes the ozone lay....... oooops we did ban it and it had no effect...

Data does not show this:
