Climate change.

Date. November 2019.
 

This has been my pet subject for nearly 40 years now. The page is new and it is created because i do know stuff on the subject and i do care that people should have the opportunity to access honest information. To understand climate change you have also to understand its long history. I have put the below information together as simply as i possibly can. My aim is to create “quick find” statistics for self learning.

 

There will probably be some minimal dysfunction in content layout because i am not from an academic background.

 

I hope some youngsters will take time to read it all as its their future we are talking about.

It is important to have some understanding of our planets ancient atmospheres history because the evolution of these atmospheres decided what life could inhabit them. We need this lovely blue sky one we have today, so read on to understand why!

 

The history has a three main periods, the start of life, old life, visible life.

 

HADEAN and ARCHEAN...This is everything that took place from the start, which is from 4.5 billion years ago till 2.5billion years ago. It introduced single cell life and then introduction of oxygen.

 

PROTEROZOIC...(the Old Life)...is from 2.5billion down to 541million years ago. From the introduction of oxygen and stops at proliferation of soft bodied organisms, just before proliferation of complex life. “Old life.

PHANEROZOIC...(the Visible Life)... is from 541million years till today.... life explodes....this is the phanerozoic era. It is from Greek meaning "visible life."

 

 

Towards the end of the Phanerozoic era is the most recent 60 million years....

the Cenozoic ......it is the age of mammals.

EXPANDING FROM THE ABOVE...

with only the very most important events of time

All the below main eras have many other very important other eras within them where great important historic changes took place. They can be studied by someone wanting a university degree. I am keeping things as simple as i can... So one could say that the below are the rooms of time without all the furniture of times inside them being described as well.

HADEAN, 4.5b to 4b (and i suspect a lot of guesswork on this far back in time)
basically a water world and at 4b first single cell life forms appeared.

ARCHEAN, 4b to 2.5b
Era of single cell and intro of oxygen into the climate.
3.5b to 2.5b where atmosphere oxygen became present

ProterOZOIC, 2.5b to 541 million years ago.
Spanning the time from oxygen in Earth's atmosphere to just before the proliferation of complex life. Period (635 to 541m) is defined by the evolution of abundant soft celled multicellular organisms and provides us with the first obvious fossil evidence of life on earth.

PhanerOZOIC, 541 million years ago to present.
Phanerozoic from greek phaeneros and zoe meaning visible life.
The PhanerOZOIC is the full life history of visible life 541m years ago to the present day and breaks down into the following...

PaleOZOIC
...541-251.9 million years ago....age of ancient life and ended in a massive extinction, the ...  Triassic Extinction.
The early period of paleOZOIC saw explosion of (Cambrian era) early life in sea and on to land.
The time of great forest and privative life which is what formed most of todays coal.

Gondwana land ........tectonic plates 550m to 180m years ago

Pangea land .............tectonic plates 335m to 175m years ago

MesOZOIC....251.9m to 66 million years ago...The age of reptiles and conifers ending with the famous .... Jurassic Extinction. 

CenOZOIC...66 million years ago to present... this is more relevant to us in todays world climate except for CO2 coal which comes from the old world



Thats the old world in simple terms. During these billions of years of time the world tectonic plates have had a ball of a time travelling all over the planet at about 25 kilometres every million years (2.5 cm a year). But thats all long gone into history. It has nothing to do with the tectonic plates format and climate we live in today.
The now famous Yucatan asteroid impact 66 million years ago has left its trace and a long recovery time passes.

 

During that time.....Tectonic plates 
The tectonic plates continue moving around the planet. The tectonic plate with India collides and forms the Himalayas, North America parts from Europe and Australia parts from Antarctica.

 

Then we arrive to where the tectonic plates started forming what we see and have today.


..................................................................................................................................................
TODAY...I am defining today as after the dinosaurs extinction. At this point in history the plate tectonics are about to start their last journey to shape todays world. All i want you to remember is that coal was made from the 'old world' above. Use your imagination on the tectonic plates moving all over the planet during these vast periods of time. Huge climate changes took place. We could not have survived in these ever changing atmospheres of the past. This was so long ago most of the history has been wiped off todays surface and scientists have to make do with the trace information left. 

At this point a completely different equation must be brought into the story. this is a very important player in our more recent climate history... MILANKOVITCH CYCLES

A lot of climate change sceptics feed from this equation.
We have been in an “ice house” climate for the past 30 million years and currently slowly coming out of it. So when we refer to todays ice ages we are referring to the 100,000 year Milankovitch cycles in the current “ice house” climate we have evolved in. The Milankovitch cycles are to do with the (astronomy) gravity effects of other solar bodies as the earth rotates the sun.
This is important because it explains what causes today, the coming and going (expanding/contracting) of ice ages within todays 30 million year old “ice house” climate.

There is more about this relevance further down, read on.

We are now referring to the short eras of todays climate.

The Pliocene time is from 5.333m (million years) to 2.58m years bp. (before present)
The age of the mammals.
This was hot times and best example for what to soon expect in todays CO2 400ppm.



The Pleistocene time 2.58m to 11,700k (thousand)  years ago and contains the Younger dryas, the 12.9k to 11.7k cold period in the slow warming curve of coming out of  our 30m years “ice house” climate.
Man appeared 300k years ago, first language about 50k years ago and first signs of any agriculture was about 10k years ago.

Now comes HUMANS...what a long time to get here and what a short time we have been here.

The holocene time is 11,000 years ago to today, from the end of the most recent ice age. Then rapid growth of human population in last 100 years.

 

That is the basic background history which is required so to understand why scientists are worried about climate change. ..................................................................................................................................................
 

Reading the ancient history should give you a feel of just how long ago "long ago" can be. It can be so long ago that it becomes too alien a planet to judge anything of today on. But there is climate history scars and clues left for scientists to use when speculating what will happen if we burn fossil fuel and add extra carbon CO2 smoke into todays carbon cycle.

 

This is important...

We should only refer back to the start of the “Pliocene” because if we go further back we start shifting the tectonic continental plates a good bit and that makes the oceans shapes, currents, climate weather and of course the landscape map different to todays world map. Its todays world we live in and we require todays climate to survive.
 

Note...
Concentrations of CO2 in the atmosphere were as high as 4,000 ppm during the Cambrian period about 500 million years ago to as low as 180 ppm during the past two million years.

During all this humongous long time Earth had periods of very different atmospheres to todays lovely clean (atmosphere) blue sky. If there is an atmosphere change, and thats what we are doing by adding CO2ppm, you change the climate and extinctions take place. You dont need to be a scientist to work that one out. Thats why i wanted you to read the evolution as extinctions are well documented. For us on this continuing path, there may be survivors, but cities and lifestyles are certainly gone. Money will become what it always was, paper from a tree. When the fossil fuels were still (trees and stuff) part of that long ago existing carbon cycle, that climate was uninhabitable for humans. Put it back into the equation and you get that climate (or similar) again. You dont need to be a scientist to understand that either. This is simple logic like walking off the pavement in front of a bus. It is avoidable simplicity.

 

Stay focused because this CO2 equation should start to make sense to you now.

Two million years ago is not a long time in the world climate history but it is for us.

Two million years ago CO2 was at 180ppm and is an important point to note.

 

CO2 has been stable between 180ppm to 280ppm (parts per million) for last 800,000 years.

The CO2 measurements for the past 800,000 years have been in harmony with the 100,000 year Milankovitch cycles. The sums are simple, every 100,000 years the CO2 in the atmosphere swung from a high 280 ppm to a low of 180 ppm and the temperatures swung from +5°C to -5°C respectively at 280 ppm and 180 ppm. Its really that simple! This is most relevant. CO2 at 180ppm brings down the temperature -5˚ and into an iceage. CO2 at 280ppm raises the temperature +5˚ and we are out of the iceage. Its been behaving like a room thermostat for 800,000 years.

Burning fossil fuel creates CO2 and now, through our love for lifestyle, it is 'suddenly' over 400ppm in the atmosphere today. 400ppm has not been in our atmosphere for millions of years. This is the biggest single alarm bell on the subject of climate change and it is seriously not good.

 

Today unfortunately the CO2 is over 400ppm, busting the 800,000 years of records when 280 ppm brought in its wake +5°C, which, in the past, radically altered the planet beyond comprehension. We can only expect that CO2 at over 400ppm will soon radically change our climate. Want to get more alarmed? Have a listen here then, but only if you want to.☠️

Please note...

I have avoided truly alarming web links (example of their sincere serious work) and stuck to palatible reading.

The extreme statistics can be best described as information that we "really dont want to know" but a lot of it can not be dismissed because of the statistics. There is a real danger of sticking your head in the sand after reading their stuff. I dont want you to do that, so please dont. That does not help your future. 

 

My aim is simply to help you to understand the equation. There are many people doing this and  everyone doing so has a different way of expressing their thoughts. I am adding mine and hope that it contributes to some more light (brain cells) bulbs getting switched on. You can then decide for yourself what to make of it all.

 

There is no easy answer to the CO2 problem for sure but i would rather the young generation understand the urgency, be well informed and self motivated, empowered to do something constructive about Climate Change.

I see an irony with our world population explosion and the effect we put upon the planet. According to the scientists evolving statistics the irony is that the more you defend your lifestyle the quicker you will loose it all.

Now go back to why we should be concerned as it should make better understanding after reading this page.

 

I hope it has been of interest.

I think this is a very good read... by Veli Albert Callio 24th April 2017

 

I love this one....just type in a number like 300 and see the result on the tectonic plates of time 300 million years ago.

 

Europes ever changing borders.....one thing for sure is that changing borders never solved disharmony in the long run. We are our own worst enemies for sure. WDYT

Statistics are being improved every year because of  NEW TECHNOLOGY and field work by scientists. Just for the record, most new, latest information regularly turns out to be worse than previous. One comes to realise that this climate change subject is continually being played down. You are now this year 2019 beginning to see a lot about Climate Change in the media. This is good.

The below are older links of interest.

A video

Natallia Shakova...VIDEO

This was 6 x years ago. At the end of the video you can visibly see her emotional concerns.

Of course this year 2019 they are seeing some increasing signs of what she was so concerned about. This lady is one of the most informed individuals on the planet regarding what is going on in the arctic.

Just stuff to read

Sometimes just reading mixed miscelaneous stuff helps to get to grips with what is being explained. A sort of attacking it from different angles.

There is just so much stuff to read. So much crap from all sides of the debate. Statistics are just thrown about all over the place by people indulging in attention seeking. Unfortunately, this is what we have to deal with today. Honesty contaminated by fake news is 2019s reality and honest information is difficult to trust. I have this in mind while doing this. I have done my honest best to keep away from any misinformation. However, the statistics are always being updated and the information on Climate Change is becomming better quality every year. It is important to keep reading the latest information. The scientists are producing new reports every day.
