    Earth just hit a terrifying milestone

    Earth just hit a terrifying milestone for the first time in more than 800,000 years

    The average concentration of carbon dioxide in Earth's atmosphere just topped 410 parts per million, according to measurements from Mauna Loa Observatory in Hawaii.
    It's the highest CO2 level in the 800,000 years for which we have good data.
    This is expected to have a catastrophic effect on human health and the planet itself.
    We have a pretty good idea of what Earth's atmosphere has looked like for the past 800,000 years.

    Humans like us — Homo sapiens— evolved only about 200,000 years ago, but ice-core records reveal intricate details of our planet's history from long before humans existed. By drilling more than 3 kilometers deep into the ice sheets over Greenland and Antarctica, scientists can see how temperature and atmospheric carbon-dioxide levels have changed since then.

    From that record, we know the atmosphere and the air that we breathe has never had as much carbon dioxide in it as it does today.

    For the first time in recorded history, the average monthly level of CO2 in the atmosphere exceeded 410 parts per million in April, according to observations at the Mauna Loa Observatory in Hawaii.

    The record is not a coincidence — humans have rapidly transformed the air we breathe by pumping CO2 into it over the past two centuries. In recent years, we've pushed those gas levels into uncharted territory.

    That change has inevitable and scary consequences. Research indicates that if unchecked, increased CO2 levels could lead to tens of thousands of pollution-related deaths, reach a point at which it slows human cognition, and contribute to rising sea levels, searing heat waves, and superstorms that scientists project as effects of climate change.

    "As a scientist, what concerns me the most is what this continued rise actually means: that we are continuing full speed ahead with an unprecedented experiment with our planet, the only home we have," Katharine Hayhoe, a climate scientist, said on Twitter.

    Breathing the air of a new world
    For the 800,000 years for which we have records, average global CO2 levels fluctuated between about 170 ppm and 280 ppm. Once humans started to burn fossil fuels in the industrial era, things changed rapidly.

    Only in the industrial era has the number risen above 300 ppm. The concentration first crept above 400 ppm in 2013, and it continues to climb.

    There's a debate among scientists about the last time CO2 levels were this high. It might have been during the Pliocene era, 2 million to 4.6 million years ago, when sea levels were 60 to 80 feet higher than today. Or it may have been in the Miocene, 10 million to 14 million years ago, when seas were more than 100 feet higher than now.

    In our 800,000-year record, it took about 1,000 years for CO2 levels to increase by 35 ppm. We're currently averaging an increase of more than 2 ppm a year, meaning we could hit an average of 500 ppm within the next 45 years.

    Humans have never had to breathe air like this. And it does not seem to be good for us.

    Global temperature tracks very closely to atmospheric levels of CO2. The potential effects of higher average temperatures include tens of thousands of deaths from heat waves, increased air pollution that leads to lung cancer and cardiovascular disease, higher rates of allergies and asthma, more extreme weather events, and the spread of diseases carried by ticks and mosquitoes — something we're already seeing.

    Higher levels of CO2 also exacerbate ozone pollution. One 2008 study found that for every degree Celsius the temperature rises because of CO2 levels, ozone pollution can be expected to kill an additional 22,000 people via respiratory illness, asthma, and emphysema. A recent study found that overall, air pollution already kills 9 million people every year.

    Other research has raised even more concerns. The average CO2 level doesn't represent the air most of us breathe. Cities tend to have far more CO2 than average — and those levels rise even higher indoors. Some research indicates that it may have a negative effect on human cognition and decision-making. (There's a full list of possible ways climate change will affect human health on an archived Environmental Protection Agency page.)

    President Barack Obama's EPA ruled in 2009 that CO2 was a pollutant that needed to be regulated under the Clean Air Act, though the Trump administration is reevaluating that ruling.

    Drowning in CO2
    The human-health effects of CO2 increases are just one part of the bigger story here.

    The change we've seen in CO2 levels recently has been much more rapid than the historical trends. Some experts think we're on track to hit 550 ppm by the end of the century, which would cause average global temperatures to rise by 6 degrees Celsius. For context, the increase in superstorms, rising sea levels, and spreading tick-borne disease that we're already seeing comes after a 0.9-degree rise.

    Data from Parrenin et al., 2013; Snyder et al., 2016; Bereiter et al., 2015.Ben Henley and Nerilie Abram/The Conversation
    Projections of sea-level rise will only get bigger as CO2 levels continue to climb.

    Right now, carbon-dioxide emissions are still rising. The goal set in the Paris agreement on climate change is to limit the global temperature increase to 2 degrees Celsius or less. But as a recent feature in the journal Nature put it, we're on track for more than 3 degrees of warming.

    The latest measurements from Mauna Loa show that if we want to avoid that, we'll need to make some dramatic changes very quickly.

    Promoting the idea we need to try and limit ourselves to one kid, and I'm not talking about ham fisted government that controls you, but teaching people we need to reduce the population as there just to many of us.

    Mention Global Warming or Climate Change and I immediately become I happen to know that this is a Illuminati/Deep State REALITY Climate Change is meant to destroy capitalism in the NEW WORLD ORDER.....has nothing to do with TEMPERATURE. Also, please understand that the UN (United Nations) is under total DEEP STATE CONTROL and has been since its beginning.

    Figueres Christiana
    A shocking statement was made by a United Nations official Christiana Figueres at a news conference in Brussels. Figueres admitted that the Global Warming conspiracy set by the U.N.’s Framework Convention on Climate Change, of which she is the executive secretary, has a goal not of environmental activists to save the world from ecological calamity, but to destroy capitalism. She said very casually:

    “This is the first time in the history of mankind that we are setting ourselves the task of intentionally, within a defined period of time, to change the economic development model that has been reigning for at least 150 years, since the Industrial Revolution.”

    She even restated that goal ensuring it was not a mistake: “This is probably the most difficult task we have ever given ourselves, which is to intentionally transform the economic development model for the first time in human history.”

    I was invited to a major political dinner in Washington with the former Chairman of Temple University since I advised the University with respect to its portfolio. We were seated at one of those round tables with ten people. Because we were invited from a university, they placed us with the heads of the various environmental groups. They assumed they were in friendly company and began speaking freely. Dick Fox, my friend and Chairman of Temple, began to lead them on to get the truth behind their movement. Low and behold, they too admitted it was not about the environment, but to reduce population growth. Dick then asked them, “Whose grandchild are we trying to prevent from being born? Your’s or mine?”

    All of these movements seem to have a hidden agenda that the press helps to misrepresent all the time. One must wonder, at what point will the press realize they are destroying their own future?

    Huh. If this were really that catastrophic, I guess we can expect people to be keeling over in the streets, behind the wheel of their vehicles and not waking up at all in the morning.

    But then, I grew up in smokestack suburb of a steel-producing city. Before there was a "Clean Air Act". If all that was so deadly, I shouldn't be here right now. And I should have asthma, COPD, or worse.

    Global warming, global cooling and, finally, climate change have all been constructs of globalists to use as an avenue for redistribution of wealth. Look how much it distributed to Algore.

    Earth changes are normal and cyclical. Look it up.
