A global team of more than 11,000 scientists is warning that the planet “clearly and unequivocally faces a climate emergency.”

In a report published Tuesday in the journal Bioscience warns in no uncertain terms that the world would face “untold human suffering” if it does not make deep and lasting shifts in human activities that contribute to climate change.

The study, called the “World Scientists’ Warning of a Climate Emergency,” was led by ecologists Bill Ripple and Christopher Wolf of Oregon State University, and climate scientist William Moomaw of Tufts University, along with scientists from universities in South Africa and Australia. The signatories to the report represent several fields of study and come from 150 countries.

“Despite 40 years of global climate negotiations, with few exceptions, we have generally conducted business as usual and have largely failed to address this predicament,” the study says. “Climate change has arrived and is accelerating faster than many scientists expected.”

It is the first time a large group of scientists have collectively used the world “emergency” in reference to climate change.

The report identified six areas that need to be addressed immediately.

They include:

  • Cutting fossil fuel use by imposing carbon taxes and using energy more efficiently
  • Stabilizing global population growth by strengthening women’s rights and making family planning services “available to all people”
  • Cutting emissions of pollutants like soot and ethane
  • Moving to a more plant-based diet
  • Preventing the loss of biodiversity and the destruction of forests
  • Moving the global economic focus away from growth of wealth to sustainability and income equality

The scientists said it will most likely take strong actions by the public to move politicians toward adopting lasting policy changes.

“We believe that the prospects will be greatest if decision-makers and all of humanity promptly respond to this warning and declaration of a climate emergency, and act to sustain life on planet Earth, our only home,” the paper said. (VOA)

Mars Losing Water Faster Than Expectations of The Scientists

The ExoMars rover will travel across the Martian surface to search for signs of life

Mars may have been a place brimming with water in the form of seas, lakes and rivers once but all of that evaporated into space as researchers now report that the Red Planet is losing water faster than expected.

Mars today is cold and dry – a desert world — but dry river valleys and lakebeds suggest that water covered much of the Red Planet billions of years ago. Previous research has also found that Martian water mostly escaped into space.

The gradual disappearance of the water occurs when sunlight and chemistry turn water molecules into the hydrogen and oxygen atoms that they are made up of. When they are broken down, Mars’s weak gravity is unable to keep hold of them and they disappear off into space, according to the study, published in the journal Science.

In the new study, an international research team, led partly by Franck Montmessin from French National Centre for Scientific Research in France, revealed that water vapour is accumulating in large quantities and unexpected proportions at an altitude of over 80 km in the Martian atmosphere.

The development was spotted using the Trace Gas Orbiter probe that was sent to the Red planet on board the ExoMars (Exploration of Mars) mission, run by the European Space Agency (ESA) and its Russian counterpart Roscosmos.

Measurements showed that large atmospheric pockets are even in a state of supersaturation, with the atmosphere containing 10 to 100 times more water vapour than its temperature should theoretically allow.

“With the observed supersaturation rates, the capacity of water to escape would greatly increase during certain seasons,” the authors wrote. The researchers point out that seasonal changes were the key factors behind how water vapour was distributed in the Martian atmosphere.

The 2020 mission of the ExoMars programme will deliver a European rover and a Russian surface platform to the surface of Mars. A Proton rocket will be used to launch the mission, which will arrive to Mars after a nine-month journey.

The ExoMars rover will travel across the Martian surface to search for signs of life.
