Any attempts to engineer the climate are likely to result in "different" climate change, rather than its elimination, new results suggest. Prof Ken Caldeira, of Stanford University, presented research at a major conference on the climate risks and impacts of geoengineering. These techniques have been hailed by some as a quick fix for climate change.
But the impacts of geoengineering on oceans, the water cycle and land environments are hotly debated. They have been discussed at a meeting this week of 12,000 scientists in Vienna. Researchers are familiar with the global cooling effects of volcanic eruptions, seen both historically and even back into the deep past of the rock record. With this in mind, some here at the European Geosciences Union General Assembly ( http://www.egu2015.eu ) have been discussing the possible worldwide consequences of pumping sulphate aerosols into the stratosphere to attempt to reflect sunlight back into space and cool the planet.

Good answer.
I've long been convinced that mankind's most harmful affects on the environment is deforestation. People see the lack of vegetation in a desert as the result of to little moisture. Looking at it from another angle, we can just as easily say that there is little moisture because there is so little vegetation to hold the moisture. Much of the mideast was very fertile, thousands of years ago. Today - much of it is desert. What happened? Well - they cut down the trees, over grazed the pasture lands, and when nothing else could subsist on the drying land, they put goats on the land to finish killing off the vegetation.
Want to save the earth, as we know it? Plant some trees. World Wide Arbor day! If a tree won't grow where you live, plant some shrubs. If there's not enough moisture for shrubs and bushes, plant some drought resistant grass. Let's turn the world green, with photosynthesis!!
Good news for those who are worried about carbon dioxide. Planting all that green stuff will sequester BILLIONS of tons of carbon!!
