"We Just Breached the 410 PPM Threshold for CO2
Carbon dioxide has not reached this height in millions of years."

On Tuesday, the Mauna Loa Observatory recorded its first-ever carbon dioxide reading in excess of 410 parts per million (it was 410.28 ppm in case you want the full deal). Carbon dioxide hasn't reached that height in millions of years. It's a new atmosphere that humanity will have to contend with, one that's trapping more heat and causing the climate to change at a quickening rate.

In what's become a spring tradition like Passover and Easter, carbon dioxide has set a record high each year since measurements began. It stood at 280 ppm when record keeping began at Mauna Loa in 1958. In 2013, it passed 400 ppm. "

...

Carbon dioxide concentrations have skyrocketed over the past two years due to in part to natural factors like El Niño causing more of it to end up in the atmosphere. But it's mostly driven by the record amounts of carbon dioxide humans are creating by burning fossil fuels.

"The rate of increase will go down when emissions decrease," Pieter Tans, an atmospheric scientist at the National Oceanic and Atmospheric Administration, said. "But carbon dioxide will still be going up, albeit more slowly. Only when emissions are cut in half will atmospheric carbon dioxide level off initially."

Even when concentrations of carbon dioxide level off, the impacts of climate change will extend centuries into the future. The planet has already warmed 1.8°F (1°C), including a run of 627 months in a row of above-normal heat. Sea levels have risen about a foot and oceans have acidified. Extreme heat has become more common.

All of these impacts will last longer and intensify into the future even if we cut carbon emissions. But we face a choice of just how intense they become based on when we stop polluting the atmosphere.

Right now we're on track to create a climate unseen in 50 million years by mid-century.

Hmm, so all of that money the world has blown on "sustainable" energy has not done a damn thing to help. Since that is obviously a futile waste of money, we should start saving to rent moving vans instead. In the meantime, I am still willing to buy up your beach houses at 75% of current value, which would allow you guys to buy a nice place in the mountains. I am too nice to you people.

When the ecosystem collapses and human population (our kids and grand kids) is cut in half our carbon emissions will go down and warming will reverse. It's a natural cycle. But more importantly your taxes may go down next year and up again in the near future. Also a natural cycle.

My beach house, and most are safe for decades. We will both be dead before they are threatened.

You really aren't dumb enough to buy this sort of argument, you have enough brains to understand the time scales involved so why do you persist with such weak arguments?

I don't think he has kids, so no reason to worry about the future.

I'm going to do what I can. We're accountable to our own conscience.

Denialists are the right's version of the left's vaxxers, science illiterates that show the world how stupid they are anytime they open their mouths or write about it.

Is it wrong that I find it absolutely comical when a vaxxer and a denier call each other stupid and argue with each other?

I don't think Vaxers are so common the left, a lot of them are righties.
Sam for the anti GMO crowd.

But almost the entire Republican party has bought the "climate change is not real " hoax.

Maybe the party, but not the voters. Party line politics are in play on both sides, which is why we needs new teams and players. Plenty of conservative voters believe in climate change, saying otherwise is silly.

I know liberals who don't believe in climate change, though they are typically religious and believe it is gods plan. I know conservatives that are anti vaccination, for the exact same reason. More liberals are vaxxers and more conservatives are deniers for sure, beyond a shadow of a doubt imo.

don't play to the kook lawyer's bs.  He's just trolling.  He'll be dead long before any significant impasse.  We will get to see and read about the impact on a wide variety of wildlife across the world in the interim.  

In the grand scheme of things, comparatively speaking, nothing has been spent on renewable energy.

What, one in a thousand cars is electric? Yea, that's a big help.

When, exactly, will we be flooded out?

Great argument Tpapsmear, since we cant do everything, we should do nothing, or is it that since we haven't tried to much and that didn't work, we shouldn't try anything and just treat it like it was meant to be, fate and what not.

"One of the reasons why propaganda tries to get you to hate government is because it's the one existing institution in which people can participate to some extent and constrain tyrannical unaccountable power." Noam Chomsky.

"Exactly" makes it a dumb question, but it depends a lot on what we do. If you look at the IPCC concencus, the possible range is huge. If climate sensitivity to carbon is at the low end of the range, and if we slow down enough carbon emissions to restrict warming to less than 2 degrees C this century, we, (meaning satellite beach at 15 feet above sea level) could be OK for centuries. (Miami and lots of other low lying cities are still screwed in though). On the other hand, if sensitivity is high, and we do nothing to stop the increase in emissions and we see 6-8 degree C increase global temps this century, then I wouldn't want to be owning any FL real estate in 2100. But in either case most old rich American farts likes us will escape the brunt of the problem.
