Scientist: ‘No Sun Link’ to Climate Change

Cloud cover affects temperature – but what determines cloud cover?

Scientists have produced further compelling evidence showing that modern-day climate change is not caused by changes in the Sun’s activity.

The research contradicts a favoured theory of climate “sceptics”, that changes in cosmic rays coming to Earth determine cloudiness and temperature.

The idea is that variations in solar activity affect cosmic ray intensity.

SUPPORT THE STRUGGLE FOR SURVIVAL AT BIG MOUNTAIN, BLACK MESA, AZ

FIRST NATIONS, FIRST RESISTANCE—

SUPPORT THE STRUGGLE FOR SURVIVAL AT BIG MOUNTAIN, BLACK MESA, AZ.

On behalf of their peoples, their ancestral lands, and future
generations, more than 350 Dineh residents of Black Mesa continue
their staunch resistance to the efforts of the US Government– acting
in the interests of the Peabody Coal Company—to relocate the Dineh
and destroy their homelands. This land is the basis for the Black
Mesa peoples’ traditions, livelihoods, and spirituality.

At this moment the decision makers in Washington D.C. are planning
ways to seize tribal lands to extract mineral resources. The coal
companies are funding both the Republican and Democratic parties
because they have huge interests at stake. Presidential candidate
John McCain recently sponsored forced-relocation legislation
targeting these Dineh families; Peabody Coal, the world’s largest
coal company, currently has plans to expand its strip mine operations
and to seize more deep aquifers beneath these indigenous lands.
Peabody Coal Company has completely dug up burials, sacred sites, and
shrines designated specifically for offerings, preventing religious
practices. Not only were the principal concerns of the communities
directly affected by the legislation never addressed, those
communities were not even notified.

Emission reduction assumptions for carbon dioxide overly optimistic, study says

BOULDER–Reducing global emissions of carbon dioxide (CO2) over the
coming century will be more challenging than society has been led to
believe, according to a new research commentary appearing April 3 in
Nature.

The authors, from the University of Colorado at Boulder, the National
Center for Atmospheric Research (NCAR) in Boulder, and McGill
University in Montreal, say the Intergovernmental Panel on Climate
Change (IPCC) has significantly underestimated the technological
challenges of reducing CO2 emissions. The study, “Dangerous
Assumptions,” concludes that the IPCC is overly optimistic in
assuming that, even without action by policymakers, society will
develop and implement new technologies to dramatically reduce the
growth of future emissions.
