Place à l’amélioration Économie En Vidéos États-Unis

Le système de santé américain, un système qui serait contaminé par le démon du privé et la loi de la jungle capitaliste…

Well, think again…

La plus grande privatisation du système de santé aux États-Unis fait en sorte que leur système est supérieur au nôtre. Mais ce système est loin d’être parfait; en limitant encore plus l’ingérence du gouvernement, ce dernier pourrait être amélioré.

World may not be warming, say scientists
The Times of London

The United Nations climate panel faces a new challenge with scientists casting doubt on its claim that global temperatures are rising inexorably because of human pollution.

In its last assessment the Intergovernmental Panel on Climate Change (IPCC) said the evidence that the world was warming was “unequivocal”. However, new research, including work by British scientists, is casting doubt on such claims. Some even suggest the world may not be warming much at all.

“The temperature records cannot be relied on as indicators of global change,” said John Christy, professor of atmospheric science at the University of Alabama in Huntsville, a former lead author on the IPCC.

The doubts of Christy and a number of other researchers focus on the thousands of weather stations around the world, which have been used to collect temperature data over the past 150 years. These stations, they believe, have been seriously compromised by factors such as urbanisation, changes in land use and, in many cases, being moved from site to site.

“We concluded, with overwhelming statistical significance, that the IPCC’s climate data are contaminated with surface effects from industrialisation and data quality problems. These add up to a large warming bias,” he said.
