I believe, therefore, that although it is not the case today, that there may some day come a time, I should hope, when it will fully appreciated that the power of governments should be limited; that governments ought not to be empowered to decide the validity of scientific theories, that this is a ridiculous thing for them to try to do; that they are not to decide the description of history or of economic theory or of philosophy.

Global warming likely to reduce the habitat for  native Hawaiian birds in future.

Avian malaria is a vector borne disease that is transmitted by mosquitos. So far high elevation native forests provide save environments for native/endemic Hawaiian birds. But with future warming the 'safety-line' will move up the mountains and leave less forest habitats for unique species like the I'iwi.

Hawaii's higher mountain elevations will experience larger warming than at sea level -

In my recent publication published in International Journal of Climatology it could be shown that the atmospheric temperature over the subtropical North Pacific is projected to increase in the middle troposphere temperature by a factor of about 1.5 faster than at sea level. This directly has impacts on the high elevation sites on Hawaii. This information has been used to downscale the future temperature changes with statistical methods to a fine spatial resolution.  Data can be accessed online at the Asia-Pacific Data Research-Center of the IPRC.
