There is no certain answer to this, because science has been unable to determine the cause of the present global warming trend with any degree of certainty.
First, there is the question of whether the warming is natural, man-made, or a combination of these causes.
If, as many scientists contend, the warming is due primarily to human production of so-called greenhouse gases, then it is simply a matter of removing those gases from the atmosphere more quickly than they are being added. One means of doing this is capturing CO2 (assuming that this is a contributing factor) by growing plants and then *not* oxidizing (burning) those plants - say, tilling the unused plant portions back into the soil.
If the warming trend is natural (scientists have reason to believe that the globe has been warming naturally since the ice age about 12,000 years ago), then the matter is more problematic. However, it may be possible to cool the global temperature by adding light-occluding particles to the atmosphere - as has been done by large volcanic eruptions in the past. Historically, dust ejected into the atmosphere by volcanoes has been know to cause global cooling to such an extent that crops fail (because of the cool temperatures) over very large areas of the globe - sometimes for years. A much more controlled occlusion of the sun with non-hazardous emissions could gradually cool the earth - with the coincident effect of lowering the amount of sunlight (by a fraction) that penetrates the atmosphere. Note that this could also be used to counter warming due to greenhouse gases, but the problem here is that the cure might be worse than the disease, as we would have to continue seeding the atmosphere with light-occluding matter as we continue to exude greenhouse gases.
Naturally, one might think that if both causes are contributing to global warming, solutions can also be combined to combat the problem.
A 3rd possibility is that the global warming trend we are seeing now is only temporary. 'Way back in the 70s, many scientists theorized that we were heading for a new ice age - in a matter of only a few decades. This was based on the apparent global cooling that was occurring at that time. As you can see, that theory of climatic calamity has not managed to hold the public's interest. It may well be that the so-called "global warming" is merely a few decades long period that will begin reversing itself at any time. It may also be that this is a normal warming "surge" of a type that could well have been happening periodically over the last 12,000 years (thus separating us from the ice age by fits and starts over the millenia).
The truth is, until we have something resembling conclusive evidence for at least one of the true cause(s) of the current global warming trend, we cannot logically take intelligent, effective action in combating it.
As an aside, it is interesting that the Kilimanjaro glacier has grown over the past year (though polar glaciers have shrunk). Whether this is an indication that global warming is not really global, or that the growth/shrinkage of particular glaciers is not an indication of global warming, is unknown - since we do not know why it was shrinking in the first place. (Scientists earlier this year determined, from historical accounts, that the Kilimanjaro glacier had been shrinking since before the current global warming trend began).

Ask all the Governments around the world, to slow down their development projects to gain popularity. Not to intefere too much with Nature. e.g. forests, rivers, mountains. Like 'Ram-setu' project, Badrinath projects,slow down on making highways and multi-storeys. finally, to plant as many trees as possible, wherever you find space. Give home to animals and birds.

You can't stop something the planet's been doing for 4.55 billion years.
