May global warming be reversed over time, or is the damage that man has done to the environment, irreversible?
Answer:
Hello,
(ANS) It is my understanding that according the climate scientists and the current climate change theories, we (humans) have a window of between 8years to 15years (20 yrs max) to make deep & radical changes in the way we use energy & go on causing pollution (specifically carbon dioxide emissions).
If we don't make those drastic changes i.e. reduce our carbon emissions in that time frame the window of opportunity will be lost for ever. Meaning that we will have reached a tipping point where green house gases will thus cause unstoppable climate warming. Humans wont be able to stop the global climate changes, these changes may well result in a real threat to continued human existence on this planet.
**Climate change will inevitably lead to wars over fresh clean water for example.
**Climate change will increase the spread of deserts into areas currently inhabitable.
**Climate change will lead to changes in the global weather systems, which we are already starting to see.
**The human impact upon planet earth is only one factor at work here I believe, the earth as a planet has continued to under go climate change. We in Britain have seen numerous ice ages & periods of desertification, many times over before humans arrived here. So on that basis who is to say the climate change we are starting to experience now wouldn't have happened anyway? Humans or no humans, humans may have only sped up the process with our pollution.

I think the sun will play a bigger part in the future of our planet and global warming. What man has done to the environment in some cases can be reversed, but over all, we need to look at the bigger picture. We really have little control over it. The sun could go into a massive active solar activity and we will be helpless to reverse that.
global warming is inevitable! the question is whether man has a big effect on it. or not?
Global warming is all spin (did you get the pun there?). The earth has to evolve and managed to do it all by itself before man were put here. If it weren't for the fact that the earth has gone through many changes since it came into being, we wouldn't be here now fretting about it. Scare mongery rules okay!
I'm not sure, is the increase in global temperature due to human activity or is it part of a natural cycle? If its part of a natural cycle, then there is not a lot that can be done, if the warming is artificial, then there are measures that can be taken to try and minimise the effects such as reducing the flow of carbon into the atmosphere and that's much easier said than done. Paradoxically, some scientists now believe in the scenario shown in the film The Day After Tomorrow in which the Gulf Stream would grind to a halt and plunge Western Europe into an ice age. If that were to happen, it would reduce the area for growing crops substantially and could lead to global famine. Cheerful subject this innit?
Global warming can never be reversed. We can slow the progress down by cutting carbon emissions.
Global warming is a natural phenomena but what we are doing to the planet is excellerating the effects
Global warming is happening since many years ago. We have started to see its consequences recently and then, we started researches and we, recently, reached a consensus about its causes and ways to reverse it.
Some consequences are irreversible, eg species extinted.
Some consequences will take thousands of years. eg, balance and new life chains were species have migrated
Some consequences would not take so long if humankind would reduce global temperature, ocean acidification, lack of fresh water, etc.
Unfortunately, stopping and then reducing emissions has not started yet. Emissions grow and grow. Even more. Unfortunately, bigger emitters dont want to stop growing emissions.
jesus.
Since CREATION the world has heated and cooled constantly. so i would say that the earth will start cooling again. but i guess the scientist that are saying that now can not be heard because of AL GORE .
In theory, it should be reversable. In reality, we live in a really hard to manage world. Rich people in every country over consume, and if you have money, you have the right to pollute.
The changes required at this stage are so drastic that noone will adopt them unless forced to do so. As voluntary action, the net result of a handfull of people around the world doing the right thing is inconsequential.
It will take years of strife and hardship for governments to implement new laws, by then of course, it will be too late.
I am certain that even as the Earth's ability to sustain life is strained, the world's wealty, and cockroaches, will continue to survive.

We can slow it down enough to reduce the damage to nature caused by us, if we work hard.

Reversing our impact will take a lot longer. Say, 100 years to get greenhouse gas emissions back to where they were in something like 1950. Then a few hundred years for Earth to get things back to natural conditions. There will be some differences, of course, things change naturally, but they'll be pretty minor.
It took hundreds of years to complete Notre Dame cathedral. The people who started it knew they'd never see it done. Didn't stop them from working hard.
Yes, global warming will be reversed. The Earth's energy engine, fueled by the Sun, has a massive momentum ( or inertia depending on how you want to look at it). A colony of ants have a better chance at stopping a farm tractor than man does of significantly altering this planet's global climate.
Some of the damage that mankind has done to the environment is probably irreversible,but as for Global warming ,well I think it's a far more complex issue than CO2 emissions ,after all the climate in the UK has been warmer than it is now and much colder than it is now,it's not going to stay the same either way,and of course that large yellow ball in the sky has a lot more say over it than you or I
remember:
never say never
u can always try to undo what u did
butt this hole planet is in soooo deep,
that EVERYONE will have to try and stop it
not just one, or two.
1. No one knows about global warming and its effects. These weather patterns are relatively new as opposed to just 30 years ago when we were in a cooling pattern.
2. Man can not control climate or weather. Unless you are an X-men.
3. There is no doubt we have cause a high level of polution and we will not know the effects of that fo years to come.
Your best course of action is to worry less about global warming and more about polluting your enviroment, and what you can do to help cleaning up our oceans and air.
