If CO2 causes global warming, why does it increase after global warming has occured?

Question

When global warming occured in the twenties and thirties it had nothing to do with CO2. What is different about today? The only difference I see is that you are measuring CO2 on the worlds largest active volcanoe.

I guess I deserved that, I think in twenty years everyone will wan't to live in Miami, it will be much colder then.

John Walkup your source's are just speculation, mid century cooling is because of pollution. How about a 2 watt drop in solar output.

Answer 1

Yes - In fact what we are experiencing today is not anything different than the last 500,000 years.

Looking at the proxy data from the Vostok ice cores, we can determine that it was warmer in the past than it was today.

The difference today is that there's TV and the internet to scare people en mass.

Answer 2

When one measures amounts of CO2, it's true that it's measuring the natural and man-made CO2 (being chemically identical). We can do nothing about volcanos CO2, we can do nothing about moose burps of CO2. The extent to which mankind has created CO2 (by creating more CO2 and eliminating sources that capture CO2) is where the problem is. If levels were higher in the past (millions of years ago) that is moot. Animals would simply have migrated to higher ground, and in the natural scheme plants would have flourished more, thus (in time) reducing the amount of CO2. With more people on the planet, and fewer trees, and populations crowding on the coasts around the world, any significant melt of ice (through warming) could be culturally, economically catastrophic. If we can measure and take actions that would reduce the amount that we contribute to the CO2 %, doesn't it make sense to do so?

Answer 3

The CO2 data from Mauna Loa is completely unaffected by volcanism (I continue to marvel that people think scientists are idiots).

Two independent proofs: First proof, show me the eruptions in the data:

Second proof. The data looks exactly like Mauna Loa at stations in a variety of locations all over the world. General site and one sample location:

Florida, not known for volcanoes.

What's different about today is this. In the 20s and 30s the rise in temperature was due some to greenhouse gases, and some to natural factors. These days greenhouse gases dominate. Here's a nice picture, from the source below:

CO2 used to rise hundreds of years after the Sun started warmings, as CO2 was released from warming ocean waters. Today CO2 is going up almost simultaneously with temperature, because it is the major cause of warming. This is one of many proofs that this warming is NOT natural. More details:

Answer 4

Now a days there are cars and as technology has increased the amount of CO2 in the air has also increased crossing the limit and causing the melting of ice. If human do nothing about it all the ice will melt and as a result there will be flood and lot of other destruction. There is no stop to the amount of CO2 that is released in the air. After global warming as the sea level increases all the plants are destroyed resulting in the increase in the level of CO2.

Answer 5

Increasing levels of CO2 leads to global warming

and...

Global warming leads to increasing levels of CO2

It's a feedback mechanism in which one leads to the other irrespective of which comes first. Historically warming occured first as a consequence of natural cycles, in the last 200 years humans have turned things around by releasing large quantities of CO2 and other greenhouse gases.

Human induced warming has been ongoing for about 200 years, the warming in the 20's and 30's was as much human induced as it was natural, more so in fact.

The volcano you're referring to is Mauna Loa (Hawaii), about three quarters of the way up on the northen flank are two observatories. CO2 levels are measured at the NOAA's Mauna Loa Observatory (the other is the Solar Observatory). The readings that are taken there are adjusted to allow for venting of CO2 from the volcano itself.

CO2 monitoring stations exist around the world, there's almost certainly one not far from where you are. They're in most cities, large cities have several. They're at airports, observatories, weather stations, remote islands, mountains, forests, ships etc. These measure ground and low level CO2, in addition there are extensive mid and upper atmosphere recordings.

CO2 levels are computed from millions of readings worldwide, not just from a single location.

Answer 6

CO2 is not the only greenhouse gas or force factor, when you crossed the moat did they tell you that? If you want to see the effects of large volcanoes on global warming read up on the Permian Extinction.

When the temperature rises more CO2 comes out of solution in the oceans.

Answer 7

Why can't you realize we have a problem!!!! Plain and simple if you dont want to believe that people are contributing to the warming then I'm sorry but you're being ignorant by choice...
Global Warming is natural but these unnatural data records are caused by "US"
badda bing badda boom!
****AND by the way just because I was raised and live in Miami doesn't mean i can't believe in Global Warming. If anything I am more worried because of my vulnerability to it.

Answer 8

CO2 is measured at a number of stations all over the world.
The best measurements come from the South Pole, which is far from any volcano or industrial activity.

Answer 9

Not really true, but your real problem is your sources. You can't effectively make a scientific argument and back it up with wikipedia, or something like this. Every citizen on the planet is free to blast away with their hoax and conspiracy theories, and it doesn't make one D****d one of them true.
