No, they cant, they need magic to do that and magic does not exist
They may someday have the ability to say if man has anything to do with the issue or not. They absolutely have no control over the issue itself as man only makes 0.28% of all the greenhouse gas that is attributed to global warming.
Without global warming, we would all die as it is what keeps us warm. Currently, they have missed on every prediction they have made. From 1970's claim of cooling until the 1999 reports from the IPCC stating claims of wild flooding and destruction. They missed the fat that there has been zero warming in over a decade currently. The record growth in the Arctic last fall was also missed by them. Climate is MUCH harder then the weather. How do they do with the weather?
Scientists have been using the data over the last 250 years (since the start of the Industrial Revolution) to monitor the rise of Global Warming.
There are many fears of scientists who write about global warming. Ozone depletion, floods, warming etc are some of them.
Most scientists and scientific organizations round the world agree that global warming is happening. A few scientists disagree.
Not many. Most (97% of) climate scientists agree that the earth is warming and that humans are causing global warming by burning fossil fuels and cutting down forests.
Because it is GLOBAL, not local warming.
Global Warming is a threat to Polar Ice. Because of rising temperatures in the polar regions, the ice caps are melting. Scientists predict that in a few decades from now, the polar ice caps would have fully melted.
The enhanced greenhouse effect in our atmosphere is believed to be causing global warming.
Many scientists hypothesize that deforestation intensifies global warming trends.
The work of 15 climate scientists is helping to educate the public about the overwhelming scientific evidence for human-caused global warming.
Scientists as a group do not take measures to prevent global warming other than those taken by individuals.
Global warming is no longer a theory, as it is accepted as fact by the vast majority of climate scientists.
Al Gore is not a climate scientist, but a concerned citizen who listened to what the scientists had to say. He is doing what he can to alert the world about the impending disaster climate scientists predict if we do nothing to reduce our global emissions of greenhouse gases.
