Climate Catastrophe will become a reality approximately in 2030-2040.
What, specifically, awaits us all?
What will be the real situation in our Life?
This tragedy of the all humankind will begin near 2030, but it will be not an instant flash and after it the complete darkness.
We’ll say that the Global Climate Catastrophe (GCC) has begun when Climate changes will reach such a level
that many people will be not able to live in their habitats.
Our Life on the Earth during this time can be described as three periods:
●1 period: (if to say figuratively a fire under the boiler caught fire and already the water in the boiler is noticeably heating…)
That is, in many places
the sea level will rise so much that large areas of land will constantly be flooded entirely.
In other places, droughts will become permanent and make large areas of land unsuitable for agriculture at all.
As a result, large groups of people will be forced to leave their permanent places of residence and become climate refugees.
When the quantity of such climate refugees (CRs) will become noticeable, it can be said that the GCC has begun.
During this 1-st period, the quantity of CRs will begin to exceed the quantity of war refugees who, at least theoretically, are able to return to their permanent habitats in the future.
This very big quantity of such 
CRs will lead to great stress in other countries where they will arrive.
There will be significant difficulties with food, fuel and water.
The crime rate will increase 
significantly, but the police and society will still be able to restrain criminality.
Famine will be noticeable in many places.
(But the water in the boiler still does not boil.)
▲ Whether we can prevent this future horror?
● 2 period: (the water in the boiler begins to boil)
The quantity of climate refugees will reach an unimaginable size, it will be billions of people..
Thousands of enterprises, factories and factories will be closed, as a result, hundreds of millions of people will lose work and will stay without funds for a living.
All fuel supplies will stop. Electric power outages will become a permanent occurrence. Cities will be choked with garbage.
Money will turn into simple candy wrappers, nothing can be bought for them.
Lack of food and water will cause armed clashes, first local and later universal.
The crime rate will be monstrous.
Rampancy of criminality will be more terrible than lack of food and water.
Armed gangs will fight both among themselves and with local armies.
A states will close their borders. Many governments will declare a state of emergency or martial law on their territories.
In many countries, cruel dictatorial regimes will be established.
Soon hunger and lack of water, as well as cannibalism will become a widespread ordinary phenomenon.
To see the future situation in reality, look the Film “The Road” (2009, USA), that is like documentary film about events near 2031-2033 years, the events which are waiting us all very soon.
!!! N.B. This film is very heavy, it’s not for nervous persons. It is not advertice.
●3 period: the shortest.
(The water temperature in the boiler reaches its maximum and the pressure rose so much that the boiler was about to explode…)
As it’s impossible to provide by food and simply coexist on very limited areas for billions of people because it is theoretically impossible so the BIGGEST WORLDWIDE WAR will start. 
This War will start approximately at the period of 2033-2036 and it will be the war for survival in the literal meaning of word.
As the content and sense of this War will be elementary “Either they – or we!”, so this war will continue no until the result “Who will WIN whom” – but “Who will KILL whom”.
Therefore, of course, any weapons 
will be in use, including biological and nuclear weapons.
(The boiler has exploded.)
As a result, by 2037 maybe near 10 million people will remain on the planet, and till the end of their short lives they will envy those who already died because a living in dirty and poisoned territories will be a real hell…
But, of course, the food resources for them will quickly end in these poisoned territories.
As a result by about 2040 the humans, as a species, will die out completely.
