The study 'final' report on climate change


"The climate change debate has been usurped by the 'exaggerated' and the 'deniers'," says physicist Richard A. Berkeley Muller. "It is time for scientists to return to put things in place: less distortion, more science."
In the midst of an ideological war on global warming, Professor Muller-author of "Physics for Future presidentes', has decided to stand in the middle and try even harder: to develop the most comprehensive, independent and 'final' on climate .
The study has been dubbed "The Berkeley Earth Project 'and aspires to be" a new starting point to set the record straight and try to build a consensus. " Muller, in a telephone conversation with the world, anticipates that the results will be ready in next April or May.

The Climate Change

"The scientist's work is to investigate, analyze results and in any case provide the information to the public to draw their own conclusions," says Muller. "Much of the problem has arisen at the time that scientists have tried to be too activist and have lost their credibility as researchers."
'Exaggerated' vs. 'Denial' adn the climate change.
In the bunch of 'exaggerated', Muller talks about everything from Al Gore, but has many more reservations about criticizing NASA climatologist James Hansen ("your work as a scientist has been very valid.") At the other end of the scale puts the 'deniers', who should not be confused with the 'skeptical' ("an appropriate dose of skepticism is always desirable in a scientist) and the ecology.
According to Muller, the tendency to distort climate science to incite to action "has seriously compromised the work of the UN Intergovernmental Panel (IPCC by its acronym in English). "I will be very difficult to regain credibility," he warns, "as long as the front Rajendra Pachauri."

Berkeley physicist intends to go even beyond the work done so far by the UN IPCC, by the NASA Goddard Institute or the UK Met Office, the three major global benchmarks, trapped in one way or another the "politicization" of climate science, especially after the publication of the emails from the University of West Anglia.

"We're not going to manipulate the findings, we find what we find," says Muller, who claims to be ranked along with many other scientists at an intermediate point of debate. "We are an independent, nonpartisan group. We will collect the data, we analyze and present the results.'ll Let people draw their conclusions."

The ecology and the Climate change

Muller has been proposed not only conduct the largest study to date on the evolution of the temperature on Earth since the eighteenth century, but also make measurements "more stringent climate today, with data from 39,340 stations worldwide.

With the support of the University of Berkeley (the 'laboratory' Energy Secretary Steven Chu), the study is being funded by groups of very diverse: from the Innovation Foundation for Climate and Energy Research (created by Bill Gates ) to the Charles Koch Foundation (linked to the oil magnate).

Richard Muller argues in any case the "autonomy" of the Earth Project has received funding on the grounds that "both the left and right" and trying to lend a ember researchers who have not taken a political party. His team included Professor of Statistics David Brillinger, climatologist of Georgia Institute of Technology Judith Curry, and physical Saul Perlmutter, Art Rosenfeld and Robert Jacobsen, University of Berkeley and the ecology.
According to Muller, the evaluation "independent" global warming may be used as a reference in the U.S. and worldwide, "although we assume that a minority opinion will never change even though the evidence is or is not on your side" .

"Can we reach the same conclusions as other groups, but we will do a new and different," says Berkeley driver of Earth Project. "If all we get is permir consensus on global warming-a true consensus, rather than one based on policy positions," it will be a major achievement. "

The EC adopted for the first time in 12 years a GM crop

The European Commission has approved the cultivation of genetically modified potatoes. This is the first authorization in the last twelve years in the European Union.

Brussels has also accepted the marketing in Europe of three varieties of GM maize from Monsanto's MON 863 maize, according to a statement by the EU executive.

The real novelty is the authorization Amflora potato, a tuber designed by BASF for the industrial use of animal feed. The European Commission gave its green light to GM crops in Europe since 1998.

Climate change becomes promiscuous to a monogamous frog in Peru

There in the Amazon jungle of Peru, a poisonous frog species that, because of climate change, has left to throw practice monogamy in promiscuous attitude to the hunt for suitors that guarantee their survival.

Explains the professor of the Natural History Museum of Peru Ricardo Palma University, Victor Morales, these frogs have changed their reproductive behavior, primarily due to decreased water in the ponds they inhabit.
Climate change and habitat destruction are behind the phenomenon that Morales in March detailed in the publication 'The American Naturalist', with researchers Jason Brown and Kyle Summers.
Most frogs are polygamous

According to the professor, most frogs are polygamous but this particular species, called 'Ranitomeya variabilis', only a couple pairs with beneficial environmental conditions, ie when there is enough water in the tanks of bromeliads where you live.

For thousands of years, the mother only made one or two eggs and neither she nor the male left the home when it came to care for the young.

However, current environmental constraints have changed this behavior, so now think only males and females to ensure their offspring and have been reproduced more individuals.

To demonstrate this new stage adaptation in frogs, Professor Peruvian conducted in recent years, analysis of water and larvae in the tropical forests of Tarapoto and the conservation area of the Cordillera Escalera in northern Peru.
The aforementioned poison frog is abundant in these forested areas where it has been found promiscuity traditionally monogamous species because genetic differences have been found within the same brood.
Included in the red list of threatened species

Toxic skin and colorful, these amphibians are prey diurnal snakes and other predators, but now they face a hostile environment in which the tadpoles are dying and even eat each other over the lack of space and water.

Peruvian biologist Marina Rosales said that global warming and the destruction of the Amazon particularly affect the flora and fauna of wet environments, including this frog is found, including in the red list of threatened species.

In his view, this scientific discovery, apparently "anecdotal" should be interpreted as an indicator that environmental conditions are changing, forcing the amphibians to be more concerned than before about leaving a larger number of offspring and thereby ensure the survival of their genes.

Faced with this predicament, much like Professor Rosales Morales found that amphibians, like other species, they adapt and fight for their survival, but this flexibility is limited and in any case, it is not beneficial in the long term.

Therefore, the specialist of the National Natural Protected Areas by the State (SERNANP) warned that this is not an isolated case, as humans must take actions necessary to mitigate adverse effects on climate and biodiversity .
