look at the Database section by clicking on the top menu. The database includes: more than 900 operational satellites,  approximately 150 launchers,  all spaceport from where the satellites were launched,  nearly 400 key stakeholders in the sector.

Global change and the satellites

There is a common agreement on the global warming, i.e. the average increase of world temperature in the last few decades. The debate is on the causes, whether it is an anthropogenic climate change or not. Climate is a very complex matter: we don’t have simple deterministic models neither elegant theories like the Einstein’s relativistic ones. From one side we have many scientists (a majority) who support anthropogenic climate change option. NASA’s scientific community is openly deployed for the anthropogenic option and clearly identify with the the Intergovernmental Panel on Climate Change:

In its recently released Fourth Assessment Report, the Intergovernmental Panel on Climate Change, a group of 1,300 independent scientific experts from countries all over the world under the auspices of the United Nations, concluded there’s a more than 90 percent probability that human activities over the past 250 years have warmed our planet. (link to NASA web page).

Other experts deny such an evidence. Somebody openly evoke the role and relevance of international bureaucracies. Other scientists reckon that we don’t have a strong evidence to discriminate between the two opposite parties. One interesting portrayal of the last viewpoint is from the italian scientist Antonino Zichichi in the paper  METEOROLOGY AND CLIMATE: PROBLEMS AND EXPECTATIONS.

For sure the importance of Satellite Remote Sensing for Global Change Research is increasing.

So let’s point our antennas and see the course of the debate.
