People forget we are in a warming period and have been since the last ice age 11,700 years ago. There have been at least five documented major ice ages during the 4.6 billion years since the Earth was formed — and most likely many more before humans came on the scene about 2.3 million years ago.
The last one typically defined as the Pleistocene Epoch was the time period that began about 2.6 million years ago and ended 11,700 years ago since then we have been in the planets warming system.
At the time of the Pleistocene, the continents had moved to their current positions. At one point during the Ice Age, sheets of ice covered all of Antarctica, large parts of Europe, North America, and South America, and small areas in Asia. In North America, they stretched over Greenland and Canada and parts of the northern United States. The remains of glaciers of the Ice Age can still be seen in parts of the world, including Greenland and Antarctica.
But the glaciers did not just sit there. There was a lot of movement over time, and there were about 20 cycles when the glaciers would advance and retreat as they thawed and refroze. Scientists identified the Pleistocene Epoch’s four key stages, or ages — Gelasian, Calabrian, Ionian, and Tarantian. The name Pleistocene is the combination of two Greek words: pleistos(meaning “most”) and kainos (meaning “new” or “recent”). It was first used in 1839 by Sir Charles Lyell, a British geologist, and lawyer.
As a result of Lyell’s work, the glacial theory gained acceptance between 1839 and 1846, and scientists came to recognize the existence of ice ages. During this period, British geologist Edward Forbes aligned the period with other known ice ages. In 2009, the International Union of Geological Sciences established the start of the Pleistocene Epoch at 2.588 million years before the present.
We are now due to another ice age and it's that what we should be concentrating on because as our planet's population gains strength we have to feed that population. Food that we eat, plants will not grow unless we have heat. Animals that we eat will have to adapt to the cold or die and become extinct. That means that Humans will die and become extinct.
If we can't grow our food because our land is covered by ice, if the animals cant graze because of the ice then life as we know it will change and for the worse.
What the Warmegedinists will never tell you is that our world revolves around CO2 it is life-giving, it keeps us all alive, plants that we rely on, rely in turn on CO2 to grow and feed us. They also forget that our nearest Star is life-giving and that among anything else controls our climate. Our nearest star the Sun as we call it also has periods where it changes our climate in the Sun’s brightness can change global temperatures. At the moment we are seeing a great change.
The Sun has what is known as Sun Spots. You can see sunspots if you look at the sun through a telescope with a very dark lens ( never look at the sun without one) Sunspots can be very large, up to 50,000 kilometers in diameter. They are caused by interactions with the Sun’s magnetic field which are not fully understood. But a sunspot is somewhat like the cap on a soda bottle: shake it up, and you can generate a big eruption. Sunspots occur over regions of intense magnetic activity, and when that energy is released, solar flares and big storms called coronal mass ejections erupt from sunspots.
The bigger the sunspot storms the more frequent they are the warmer the planet becomes. At the moment we are in a decline of sunspots erupting and have been for quite a few years. This means that our earth is becoming cooler not as the Warmegedinists are saying warmer.
We will nor see a great change for at least 200. What we will see is that our summers becoming cooler until one day our future generation will wake up one morning to see snow on the ground in their summer months. depending on where they live in the world.
We have around 200 years maybe 300 to think of a way for us all to exist. Because once it starts in earnest we will be unable to stop it. Its happened before and its now happening again. The clock is ticking and it's our greatest challenge to date. Better get cracking now or become responsible for the extinction of the future human race.
