Adapt

It is time to adapt to unstoppable global warming, scientists say

Even if the world’s 7 billion people magically stop burning fossil fuels and chopping down forests today, the greenhouse gases already emitted to the atmosphere will warm the planet by about 2 degrees Fahrenheit by the end of this century, according to scientists who are urging a focused scientific effort to help humanity adapt to the changing climate.

And reality shows no sign of such a magic reduction in emissions. The amount of greenhouse gases in the atmosphere reached another new high in 2012, the World Meteorological Association announced Wednesday. In fact, concentrations of carbon dioxide, the most abundant planet warming gas, grew faster last year than its average growth rate of the past decade.

Critters evolve rapidly to cope with environmental change

Critters can evolve over just a handful of generations to survive whatever environmental maladies humans toss their way, from climate change to over fishing, suggests a new study.

“That is the first take-home message, and it is a positive message,” Thomas Cameron, a biologist at Umea University in Sweden, told NBC News as he explained his new findings reported Tuesday in the journal Ecology Letters.

Swallows evolve shorter wings to avoid cars, study suggests

Cars and trucks thundering down the road in southwestern Nebraska stand a much lower chance today of smacking a cliff swallow than they did in the 1980s, according to a new study that suggests the birds have evolved shorter wings to pivot away from oncoming traffic.

The adaptation is important for the birds’ survival given that they nest by the thousands under bridges and overpasses there, noted Charles Brown, a biologist at the University of Tulsa in Oklahoma who regularly drives those same roads to and from a nearby research station.

How we’ll eat the same with climate change

Want a varied, abundant, and healthy diet in the decades ahead? Then be glad that researchers are beginning to pinpoint the genes that allow plants to thrive and adapt to different climates.

That’s because our agricultural system is largely adapted to perform in today’s climate, which despite some warmer and cooler swings over the past 10,000 years or so, has been relatively stable.

That’s unlikely to be the case in the future, meaning we will need to adapt our agricultural system to a changing climate if we aim to maintain our current eating and drinking habits.
