What percent of earth's atmospheric gases by volume is CO2?

We can tell that you're a scientist, since you work at a real estate company!

Kerem Oner... You pulled the 3% figure of CO2 due to man from where, Einstein wannabee? The truth is man now releases 40% more CO2 than at the start of the industrial revolution. And that is increasing yearly. Not to mention, carbon dioxide just happens to be at an 800,000 year high in our atmosphere. And if you are such a scientist, you must realize carbon dioxide readily dissolves into lakes and oceans when there is more of it in the air. In water, it quickly reduces the pH and adversely affects aquatic life. Which we depend on to eat. In my home, all I have to do is turn on my gas oven and the pH in my aquarium drops .2 points in 30 minutes. This as measured my a highly accurate electronic monitor. Let's not be willfully ignorant. We can't pour endless smoke from burning fossil fuels into this planet's atmosphere forever without serious repercussions. Did you submit to a lobotomy when you signed on to be a Republican?

Data from 1990 and references in your source to an nutty blog called hockeyshtick? Being a scientist does not come from reading right wing denial websites. Are you high, Einstein wannabee? You are dismissed.

Kerem Oner, Tea Party. LOL. I knew you were. You are another Sarah Palintardo type. You must need a drool bucket everywhere you go.

Yeah, research like you do on right wing blogs. You know more than Hawking. ROTFLMFAO!!! What a miserable fool you are.

Simpleton Kerem Oner, the idea of you being employed as a coordinator is hilarious. You would struggle coordinating a two car parade.

Kerem Oner, i know more science in my little toe than you will ever know. What is melting the arctic ice at alarming rates? Simple. 9 of the 10 hottest mean temperature years are in the last decade. You deniers think if it was cold somewhere one day that it disproves everything. Study something simple that will get through yohr thick melon. Start with the difference between weather and climate. F you, thimble-brained moron.

Kerem Oner, you should focus on syntax. You can't even present a coherent argument.

babafrby, if you have such disdain for this site why are you still visiting it?

Ben Totuous, Kerem Oner, Ben is correct. Data shows that for at least 650,000 years, greenhouse gases have fluctuated consistently. A greenhouse gas is a gas in an atmosphere that absorbs and emits radiant energy within the thermal infrared range. ... The primary greenhouse gases in Earth's atmosphere are not just CO2, but water vapor, methane, nitrous oxide, ozone AND carbon dioxide. Until recently, greenhouse gases have never been higher than they were in 1950. The levels are now twice what they have EVER measurably been. Please see the chart that is featured prominantly in the following link: https://globalclimate.ucr.edu/resources.html The only difference is man's burning of fossil fuels which has measurably warmed the planet. The chart line since approximately 1900 is virtually a straight line upward; something that has NEVER been seen before. Do not think that most of this heat is retained in the atmosphere; it is retained in the oceans. Sea surface temperature increased during the 20th century and continues to rise. From 1901 through 2015, temperature rose at an average rate of 0.13°F per decade. It is the cause of coral reef bleaching and the deterioration of other marine life. The warmth of the oceans is also responsible for the melting of the polar caps and the increased severity of hurricanes. The US has experienced hurricanes of greater power with greater frequency because of rising atmospheric and marine temperatures. Life's balance in the environment is very fragile and we are, without a doubt, interfering with that balance. They say in ignorance is bliss. You must be very happy.

My daughter helped me with this question as she is a climatological.. sorry about that!!

Darlene Davidson, Don't feel special

Kerem Oner, go north of your country. Not just a bit. Near the poles where glaciers are melting at an accelerated pace. Where the pergelisol, that traps huge quantities of methane, wich is far more dangerous than C02 as a greenhouse gas. Ask the Inuits about the shortened winters. They can tell you about the day last February when they got a day at 0 degrees celsius, 30, yes thirty degrees warmer than average. Then ask us in Eastern Canada about our wi ters now, hen instead of getting snow srorms and an occasional ice or rain storms, our last three winters, we get few all snow storms. And then, seek climatology maps that show month after month, year after year, that the temperatures are consistenly warmer than the a erage. There is a solutely no doubt that the pkanet is heating up. And it is certain that we humans are the main culprit.

An interesting trivia question and explanation ... but you needed to lose the citation in your explanation ...

Got it

Huh; one of those times when the comment section is far more interesting than the game itself.

babafrby, WRONG!! Rounded up Co2 makes up 0. 040. At 50% we'd all be dead. Try to science once in a while

GOT IT CORRE3CTLY

What a disgraceful display of name calling by 2 people who profess to be educated. If you're going to debate you'd garner much more respect by doing it civilly!

I thought there was more CO2 in the air due to needing photosynthesis to help produce oxygen from green plants. .039% seems very small

ok what ever

Ben Totuous, and was that monitor the one on your ankle?

A "scientist" who scores more points on sport....surprise surprise!!!! lol

Kerem Oner, emphasis on AMATEUR. Get some real education.
