Data that covers long periods of time which take into account average temperatures for the entire world, not just a local area.
They also take into account el nino and la Nina cycles and other natural phenomena which can give false conclusions if the data being looked at covers too small a period of time. For exmaple, the most recent data would like like it would show the earth is cooling, however, this is only because we're in a la Nina cycle.
they send up weather baloons which can tell them all sorts of different information.
Yes, 97% of peer-reviewed climate scientists agree that there is conclusive proof that carbon dioxide is causing global warming, which is driving climate change.
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.
The minimum time scale used by climate scientists is five years. This is why most of their data is represented by seasonal measurements (to indicate the extent of noise) and a five year running average to chart climate trends. Natural climate change during most of the Cenozoic has occurred over a hundred thousand year cycle known as the Milankovich Cycle. This has been earth's primary driver of climate for many millions of years.
Most scientists believe that the Sahara in Northern Africa changed from grasslands to desert due to a change in the Earth's orbit.
Moderate Climate!!:)

No, scientists neither create the climate, nor imagine the changes occurring within it. Instead, they measure the change.Some climate scientists are financially or politically motivated (generally by the fossil fuel industry) to find no correlation between human activity and climate change. Most scientists, however, lack any financial incentive to find one way or the other. Claims climate scientists not funded by the fossil fuel industry are financially invested in the outcomes of their research are simply false. In fact, climate scientists have an incentive to overturn the current findings. This is how scientists win fame and acclaim--NOT by upholding established findings.
We at Answers.com were hesitant to make predictions, but most of the reliable pundits, pollsters, and political scientists did make predictions: based on the available evidence, the majority said that President Obama would win. And that is exactly what happened.
Well, if they knew about how lighting effects the growth of plants (the color of the lighting), and how the climate effects the plants too, they could make a hypothesis based on that data to figure out the best conditions for a house plant to be in. Most likely in a controlled environment.
It is likely that most predictions of this sort are wrong.

No. Although Al Gore himself is not a scientist, he has listened carefully to what scientists have to say about global warming. He is concerned about scientific predictions about the potential effects of global warming on society and the world as a whole, because that is what most scientists are telling him.
Scientists working in a research station sleep in dormitories and eat in cafeterias. Scientists working in field camps sleep in tents and eat in mess tents.
Yes, the burning of fossil fuels for the past 200 years is accepted by most climate scientists as adding additional greenhouse gases (carbon dioxide) to the atmosphere. This is causing a global warming, which is making the climate change.
The scientists observe the changes in climate very carefully. They know that the daily changes in climate are caused by storms and fair weather moving over the Earth . They know that the seasoning changes are due to the turning of Earth around the sun.The most important cause of climate is the heating and cooling of the air.
