The scientists, almost unanimously worldwide, are repeatedly telling us that we must do something about the world climate change- reining in carbon emissions, etc. - or else a host of rather dire consequences are bound to happen. Rising sea levels (resulting in some Pacific islands being submerged) or excessive climate variations giving rise to shortages of water (hello California right now!) or crops failing, as but 2 examples.
Now, the latest warning how we are facing the loss of 1 in 6 of the plants and species we know.....
"Climate change could drive to extinction as many as one in six animal and plant species, according to a new analysis.
In a study published Thursday in the journal Science, Mark Urban, an ecologist at the University of Connecticut, also found that as the planet warms in the future, species will disappear at an accelerating rate.
“We have the choice,” he said in an interview. “The world can decide where on that curve they want the future Earth to be.”
As dire as Dr. Urban’s conclusions are, other experts said the real toll may turn out to be even worse. The number of extinctions “may well be two to three times higher,” said John J. Wiens, an evolutionary biologist at the University of Arizona.
Global warming has raised the planet’s average surface temperature about 1.5 degrees Fahrenheit since the Industrial Revolution. Species are responding by shifting their ranges.
In 2003, Camille Parmesan of the University of Texas and Gary Yohe of Wesleyan University analyzed studies of more than 1,700 plant and animal species. They found that, on average, their ranges shifted 3.8 miles per decade toward the planet’s poles.
If emissions of carbon dioxide and other greenhouse gases continue to grow, climate researchers project the world could warm by as much as 8 degrees Fahrenheit. As the climate continues to change, scientists fear, some species won’t be able to find suitable habitats."
