It won't be like it is now.
A large portion of the world's population lives near the ocean, and you should expect the sea level to rise a couple of meters in your lifetime.
Global warming will dramatically alter agriculture and where and when food resources can be grown and harvested. Seafood, especially large pelagic fishes, will become precious.
Populations of plants and animals will collapse and diversity will shrink considerably. Hopefully, a significant amount of wild nature can be preserved in pockets around the world ....
Wild temperature swings will be common as atmospheric and ocean currents that have reliably conveyed heat around the globe for eons falter and become unpredictable.
And don't forget that the sun occasionally erupts in gigantic flares of radiation, and that we have not seen once since the dawn of the "electric age" a century ago.
These were "standard" predictions for dystopian writing in the past, and assumed to be possibilities for the distant future. But that future is rapidly (abruptly?) appearing before our eyes, and yet huge swaths of the population remain in denial. I may or may not live to see Miami under water, but, like you, my children will see enormous change.
It will not be possible to escape the problems altogether, but you should carefully consider where to live your life, and ensure that it is a region that is less prone to the "great" catastrophes such as floods, fires, hurricanes, tornadoes, earthquakes (and why aren't we seeing more of these yet? Global Warming must be causing the crust of the Earth to expand, and I would have guessed that there would be more cracks .... ) I am tired of making myself sick so I will stop typing this list.
The human race has been a colossal
FAIL in its responsibility for the stewardship of the planet.
I have maintained my sanity throughout my life by keeping an attitude of optimism and avoiding cynicism as much as possible, but it has been getting stretched thin in recent years. There are generally 2 schools of thought: (1) everything is going to hell so I have to grab as much as I can while I still have the chance, and (2) we are all in this together and only by cooperation can the problems of the world be ameliorated. I have always been in group 2. I believe that we can only "feel good about ourselves" under this principle and it is the only way to live a good life, in my opinion. People in group 1 will always feel empty inside.
But you have to play the cards that you are dealt.
ps - never dwell on the past or fret over what could have been, even though humans have been fantasizing over "time machines" for centuries - don't waste your time!
