They reached a daily average above 400 parts per million, reported NOAA, for the first time in human history.

The milestone, hit on May 9, may be symbolic, notes Climate Central, but manmade CO2 emissions from the burning of fossil fuels continue to rise, bringing greater atmospheric warming and exacerbating the effects of climate change.

Scientists argue we've loaded the "climate dice" in favor of more weather anomalies and extreme heat waves.

Research also shows that continued emissions of long-lived greenhouse gases like carbon dioxide will mean "largely irreversible" climate change for 1,000 years even after we curtail emissions.

"The last time we're confident that CO2 was sustained at these levels is more than 10 million years ago, during the middle of the Miocene period," climate scientist Michael Mann told The Huffington Post in an email. "This was a time when global temperatures were substantially warmer than today, and there was very little ice around anywhere on the planet."

Readings are taken at the NOAA-operated Mauna Loa Observatory in Hawaii and form part of the Keeling Curve -- a continuous record of CO2 measurements dating back to 1958. Bubbles found inside Antarctic ice core samples provide a longer record of CO2 in the air for the past 800,000 years.

CO2 measurements surpassed 400 ppm in the Arctic last summer, but the readings from Hawaii mark the first time prolonged levels above 400 ppm have been observed at more moderate latitudes.

Global carbon dioxide levels fluctuate over the course of the year, reaching an annual peak in May. LiveScience explains that the cycle reveals how trees and vegetation remove more CO2 from the air during the summer, until the annual minimum is reached in October.

"Take this day and the milestone it represents to reflect on the fragility of our civilization and and the planetary ecosystem on which it depends," Al Gore urged on Friday. "We must take immediate action to solve this crisis. Not tomorrow, not next week, not next year. Now."

Funny how for years some proponents of man-made global warming have been saying that the earth is hotter now than ever before. But this article concedes that it was hotter 10 million years ago. Must have been due to all of those prehistoric cars and BBQ grills!

A fraction of one degree over the next 50 years isn't making warming worse. In fact, the computer models have failed; the temperature has not kept up with rises in CO2 as predicted by the alarmists.

hmmm but 50 years is so little.

and one must ask how fast will the earth warm up/cool down.

Well, it dropped 30 degrees here yesterday in about 45 minutes.... pretty quick I`d say.

Global warming has bypassed my area and seems to be in other parts of the country

I was going to avoid this because there are people who clearly deny what is going on.
Both for or against and argue the most ridicules facts.

The above scientist is correct, but he didn't outright deny climate change.

The reason why the Milocene was warm was because the ocean current was not fully circumventing with the Antarctic.

Basically the cold Antarctic Ocean current circumvents with warm ocean currents and the earths temperature becomes balanced.

You can't look at a small portion and claim something.

What would you think of a Car Mechanic that says your car is okay but he only looked at the engine and failed to look at the brakes?

The Earth is a integrated system.

Why do you think San Fransisco is Cold in the summer?

Simple, The Ocean Currents distributing heat/cold.

If you don't understand that these fact perhaps you shouldn't claim otherwise.

My point is climate change is happening its more of debate of if its a human cause or a natural process.

But, as Earth History has proven the earth can heal itself. But Organisms can't and that includes us.

We have more to lose than the earth does.

Every time there is a change in climate or the environment mass extinctions occur or organism are forced to evolve for the change.
(Dinosaurs being the most well known, Stromatolites both died and reappeared twice).

For example flour was previously grown in Ireland, but because of the shorter growing season potatoes were found more suitable.

The earth has changed climate 30+ times.

As mentioned, you have to look at the big picture.

This includes ocean currents, the Atmosphere, the core's declining heat, the sun, the consumption of organisms, the waste produced by organisms and chemistry.

If you can't connect all of it together or don't understand it don't say anything.

Climate change is a tricky subject because both organisms and the earth changes.

Briefly after the Precambrian, CO2 levels were so high that the only living organisms were stromatolites and marine organism because they live off of CO2 and photosynthesis, not oxygen.

Plants later came onto the planet around the Mid-Ordovician period to take advantage of the CO2.

Eventually thanks to the Plants there was enough oxygen for marine organisms to move inland.

They evolved to take advantage of the change, gradually gills became irrelevant and lungs to breath the oxygen were developed the first were amphibians and stromatolites dies out because of less CO2.

The same thing will occur. We can change the environment and earth can take whatever we through at it but the conditions for "us humans" to live will change.

Do you want to be a deny what is going on or realize climate change is occurring and evolve for the change?.

I bet those same people who deny climate change are ones who have it the hardest with the changing economic world and fail to evolve.

Users can just leave or make the choice to make less of a presence.

Katonic chose to leave, I'm taking the later of the two.

Sorry Randall, My phone auto corrects for words and I have a battered keyboard.

I have nothing against what people say as long as they are respectful.

I respect what other opinions are and I would expect to be respected in return.

I know its your website, but I would hope the same for all the other users as well.

They don't have to agree but be respectful of each other.

Well, one would expect more neutrality and respect especially with the moderators.

Its Ironic because at my university the Physical Geography department is all for Climate Change.

While the Earth Science department all the faculty members are fiercely divided.
