Is global warming real?

Yes, it is real, yes some is caused by man. The earth goes through cycles and that cycle make the ice melt creating a flood then with too much co2 in the atmosphere the earth goes into an ice age and then the earth starts to slowly heat up, the heating up melts glaciers that cause the "flood”.

The study found that 98% of the causes of global warming is carbon dioxide emissions from burning fossil fuels that has been done since the 18th century. , Land use change accounts for 30 percent of carbon dioxide emissions. The greenhouse effect is great and the world's climate will change dramatically, inevitably again.

Source ecosystem that is already used to the maximum level by overfishing and destroying large areas of forest. Six billion people now use the earth's natural resources excessively and uncontrollably. If global warming continues, the man and civilization will become extinct as the dinosaur extinction.

Scientists forecast to show an increase of 7.0 meter sea-level, low-lying areas will be flooded.

Increased awareness of the world community difficult. Educating them not to worry but to ask them to act correctly and accurately.

The size of earth has not changed so it intercepts the same amount of stuff from the sun as it always did. However changes in the atmosphere could cause the earth to retain more heat. For example lots of volcanic activity or burning lots of oil and trees=more greenhouse gasses. We can estimate what man and volcanoes have exuded into the environment over the years. Then we need to figure out where it went. We notice changes in the ocean acidity and can can thus account for like 30% of it being absorbed there. We see some still in the atmosphere. Many unknowns of course but ALL evidence points in the same direction.
I think the 3+6 foot rise in sea level in the next 100 years is inevitable no matter how much science or politics you throw at it. What is bad about it is that what needs to be done is planning for the inevitable not trying to reverse or stop it. Millions of people need to either move, change their way of life or suffer because of it.
But individual people are opportunistic and will largely act at the last minute and only as needed. Groups will shift behavior only after catastrophe. So it goes.

Climate change is the greatest environmentalthreat of our time, endangering our health, communities, economy, and national security
