Now it's NASA warning us on climate change

The sceptics keep on banging on about this and that relating to climate change - principally, out of pure ignorance, wilful or otherwise, that things aren't really changing at all, or not that much to be concerned about  - but the evidence, from reputable scientists and trusted bodies and organisations, keeps on confirming that a wake-up call on climate change is needed.

Now NASA has joined the ranks of those making predictions - which we ignore at our own peril.

"By 2100, global climate change will modify plant communities covering almost half of Earth's land surface.

Climate change will also drive the conversion of nearly 40% of land-based ecosystems from one major ecological community type - such as forest, grassland or tundra - toward another, according to a new NASA and university computer modelling study.

"For more than 25 years, scientists have warned of the dangers of human-induced climate change," said Jon Bergengren, a scientist who led the study while a postdoctoral scholar at the California Institute of Technology in the U.S..

"Our study introduces a new view of climate change, exploring the ecological implications of a few degrees of global warming. While warnings of melting glaciers, rising sea levels and other environmental changes are illustrative and important, ultimately, it's the ecological consequences that matter most."

"The model projections paint a portrait of increasing ecological change and stress in Earth's biosphere, with many plant and animal species facing increasing competition for survival, as well as significant species turnover, as some species invade areas occupied by other species. Most of Earth's land that is not covered by ice or desert is projected to undergo at least a 30% change in plant cover - changes that will require humans and animals to adapt and often relocate.

In addition to altering plant communities, the study predicts climate change will disrupt the ecological balance between interdependent and often endangered plant and animal species, reduce biodiversity and adversely affect Earth's water, energy, carbon and other element cycles."

Robert Fisk's predictions for the Middle East in 2013

There is no gain-saying that Robert Fisk, fiercely independent and feisty to boot, is the veteran journalist and author covering the Middle East. Who doesn't he know or hasn't he met over the years in reporting from Beirut - where he lives?  In his latest op-ed piece for The Independent he lays out his predictions for the Middle East for 2013. Read the piece in full, here - well worthwhile - but an extract... "Never make predictions in the Middle East. My crystal ball broke long ago. But predicting the region has an honourable pedigree. “An Arab movement, newly-risen, is looming in the distance,” a French traveller to the Gulf and Baghdad wrote in 1883, “and a race hitherto downtrodden will presently claim its due place in the destinies of Islam.” A year earlier, a British diplomat in Jeddah confided that “it is within my knowledge... that the idea of freedom does at present agitate some minds even in Mecca...” So let’s say this for 2013: the “Arab Awakening” (the t...

The NPT (Nuclear Non-Proliferation Treaty) goes on hold.....because of one non-Treaty member (Israel)

Isn't there something radically wrong here?    Israel, a non-signatory to the NPT has, evidently, been the cause for those countries that are Treaty members, notably Canada, the US and the UK, after 4 weeks of negotiation, effectively blocking off any meaningful progress in ensuring the non-proliferation of nuclear weapons.    IPS reports ..... "After nearly four weeks of negotiations, the Nuclear Non-Proliferation Treaty (NPT) Review Conference ended in a predictable outcome: a text overwhelmingly reflecting the views and interests of the nuclear-armed states and some of their nuclear-dependent allies. “The process to develop the draft Review Conference outcome document was anti-democratic and nontransparent,” Ray Acheson, director, Reaching Critical Will, Women’s International League for Peace and Freedom (WILPF), told IPS. “This Review Conference has demonstrated beyond any doubt that continuing to rely on the nuclear-armed states or their nuclear-de...

#1 Prize for a bizarre story.....and lying!

No comment called for in this piece from CommonDreams: Another young black man: The strange sad case of 21-year-old Chavis Carter. Police in Jonesboro, Arkansas  stopped  him and two friends, found some marijuana, searched put Carter, then put him handcuffed  behind his back  into their patrol car, where they say he  shot himself  in the head with a gun they failed to find. The FBI is investigating. Police Chief Michael Yates, who stands behind his officers' story,  says in an interview  that the death is "definitely bizarre and defies logic at first glance." You think?
