While we won't become extinct by 2030 like people such as Guy McPherson say, by 2050 the 7th mass extinction will be well under way, as a matter of fact it is right now.
For those of you who have not been keeping up on the latest climate change news. Within the last year 27% of the great barrier reef was pronounced dead. These reefs are home to more than 9 million different species of organism. Such a die off has never before been seen since humans started recording history. These reefs are millions of years old. As key species fall out of the ecosystem, such as bees or coral reefs, the extinction rate will increase exponentially.
take a look at some of these figures:
The amount of ODZs (ocean dead zones-low oxygen hypoxic areas) has increased exponentially since the early 1900s and can be mapped almost perfectly by an exponential function. We have the increases in industrialization, which means an increase in commerce, China being a good example and contributor, plus the contributions of this commerce and industrialization to total Global Warming trends. Total Global Warming Trends (TGWT) contribute to the ‘kill,’ increase Ocean Dead Zone frequency and size.
As of 2010 there were 96,000 sq miles of ODZs-about the size of Michigan. The surface area of earth' oceans is 140 million sq miles. This might seem insignificant. But looking at the graph of the exponential curve n2=n1 x 3^(1/3)
which fits the increase in the last 100 years. This exponential plot based on ‘e’ an inverse natural log means that the harder we try and stop it, the faster it will proceed. We can extrapolate where this number will be in 2100 and 2200, given the current increase in industrialization and the compounding factors which will also add to the overall kill.
In 2100 the amount of ODZ will exceed 1 million sq miles. 2150 18 million. 2200 86 million square miles.
At about the year 2200, the Earth’s oceans will be completely void of all life, and fail to produce oxygen altogether. 45% of atmospheric oxygen is produced by Earth’s oceans. Add to this the current rate of deforestation, and this will put atmospheric oxygen levels at around 5.4%. Homo sapiens cannot live in an atmosphere of 5.4% oxygen. Homo sapiens will be extinct.
Where does global warming fit in to the picture? As the amount of CO2 and methane (30x more potent a greenhouse gas than CO2) being pumped into the atmosphere increases globally, we will continue to see rising global temperatures. The surface temperatures will spiral upward quite suddenly as the albedo breaks past that magic number where we are losing reflectivity and absorbing heat from the sun. How high the temperatures can go is unknown, but certainly enough to bring about a 7th global extinction. At that point, all of the Northern ice has melted, causing a complete breakdown in the AMOC ( Atlantic Meridional Overturning Circulation ) system. This is where the Big Freeze we see in the Antarctic takes control of the entire ecosystem. The change in density brings about the collapse of the AMOC system in the Northern hemisphere. By now the entire Southern hemisphere is as Antarctica, under miles of ice, and creeping northward. Where once Antarctica was a tropical paradise now frozen under 4 miles of ice, so the entire planet will be consumed by ice, miles thick, and forever frozen.
The solitary reason Earth recovered 650 million years ago, leading into the Ediacaran epoch, was that at that time the Moon was close enough to the Earth to bring about sufficient cracking and tidal forces to result in the formation of liquid water once again, over millions of years, of course. However, the Moon’s distance from the Earth has increased significantly since that time, and such tidal forces will no longer occur as a result. The Moon is close enough to effect liquid water tides, but sufficient energy to bring about ice-tides is no longer possible at the Moon’s current distance from Earth. Thus, there will be no reformation of liquid water after the next ‘Snowball Earth’ event. I want to make it absolutely clear that once the Earth freezes over in this impeccably predicted ‘Snowball Earth’ event, there will be no thawing, ever. The planet will remain a frozen ball of ice hundreds of degrees below zero, indefinitely. And that will have been the last extinction event, number 7.
There is a script for a Hollywood movie in there somewhere.
