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.
This is my understanding of the history of the World climate. I hope it helps to explain the climate calamity we or some of us are starting to experience.

My aim is to create “quick find” statistics.

 

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

I will update this from time to time. I am just happy to share and hope some youngsters will take time to read it all as its their future we are talking about.

Why should we be concerned about climate change

 

 

 

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 today world 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 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 the ever changing atmosphere of the past, it was too toxic. It 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. 

 

MILANKOVITCH CYCLES...(anti-climate change people feed from this information)
 

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.

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 of over 400ppm
https://phys.org/news/2018-02-global-lessons-pliocene-epoch.html

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

 

 

 

THE SMALL PRINT DETAIL NOW UNFOLDS...

Now for the climate change equation that is of such concern to scientists. We need to note the above history of the planet to understand why it is of concern. We should only refer back to the start of the “Pliocene” because if we go further back we start shifting the platonic continental plates a good bit and that makes the oceans shapes and currents different and the landscape different to todays world.
 

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 in the last two million years.

 

Two million years ago is a long time for us to think about, but not the world climate history.

Being at 180ppm is a most important point to note.

CO2 stable at 180ppm to 280ppm (parts per million) for last 400,000 year.

It is regarding the CO2 measurements for the past 400,000 years as they 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. Burning fossil fuel creates CO2 and it is 'suddenly' over 400ppm in the atmosphere today. That is seriously not good.

 

Today unfortunately the CO2 is over 400ppm, busting the 400,000 years of records when 280 ppm brought in its wake +5°C, which, in the past, radically altered the planet beyond comprehension. It horrifies me the to think what CO2 at 400ppm will soon do to our world.

Please note...

I am not offering answers. I have none to what probably lies ahead. I have avoided the alarmist web pages links and stuck to mainstream information.

 

My aim is simply to help you to understand the problem. 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 to do something constructive.

Go to why we should be concerned

 

I hope it has been of interest.

The below is random information.

 

Some are links to lots of stuff that i have read or watched at some point. It will mostly be new information from the most recent technology or expeditions.Today is the 5th Nov 2019 and i will be adding very relevant info when i get it. The top link will always be the most up to date bit of information.

Live weather and data nullschool.net website is available to do your own fact finding on 

 

 

 

                                         ................................................................

Statistics are being improved every year because of  NEW TECHNOLOGY and field work by scientists. Just for the record, new/latest information is 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 the subject regulary in the media. It took long enough. 

The below are all a bit older stuff from the past couple of years or so.

A video

 

Peter Wadhams... VIDEO

 

James Hansen....VIDEO

 

 

Indias Dying Mother....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.

 

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 replaced 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. The scientists are producing new reports every day.
