People make climate change

A scientific report made for the US government concluded that there is clear evidence that human activities cause global climate change.

CCSP sees rising temperatures in the atmosphere as well as on the surface of the earth. However, researchers say more data is needed.

Surveying many years ago showed that the atmospheric infrastructure temperature did not increase although there was evidence that the ground temperature increased.

That contrasts with what people know about the atmosphere, so some industry scientists are skeptical.

The new report, "Atmospheric temperature trends", reviews atmospheric data and concludes that the temperature in the atmosphere is increasing.

That, according to the authors of the report, the impact of human activity on the Earth's climate is clear.

Incomplete data

But more data is needed to help clarify some points.

In general, the atmospheric temperature increases from 0.10 to 0.20 degrees Celsius every ten years since 1979 when data began to be supplied by satellites.

But that is a big distance according to the report, "It is not clear that the atmospheric infrastructure temperature is warmer, or less, than the surface of the earth."

Peter Thorne, of the British Meteorological Institute , contributed to the report saying, "We do not study the atmosphere to learn about temperature."

Mr. Fred Singer, a well-known expert in the industry, still says there is no way people can make climate change.

"Data in blessed is generally good," he said, "The problem is that they come to a conclusion unlike what data shows."

It is not easy to measure atmospheric temperature

The satellites recorded temperatures in the distance from their orbit with the earth, but were not measured in different highs.

Satellite temperature measuring devices are also old, affecting the results, especially when satellites over time are no longer synchronized.

In the case of a bubble measurement, however, the actual temperature is recorded at different heights when the balloon flies up, but then it is lost to an unrecognizable gauge.

Adjusting the data is therefore a complicated and time-consuming task.

The report proposes strengthening the infrastructure to collect accurate data in order to answer problems that do not yet have a response.
