(12-14) 04:00 PST Ashland, Ore. -- In the natural world, animals take cues about when to migrate and when to mate from the hours of daylight, the temperature and the amount of rain and snow. Here in the Applegate Valley, for example, every spring the yellow-and-black anise swallowtail emerges from its cocoon just as the wildflowers it feeds on bloom.
That's the way it's supposed to work: a natural synchronicity between seasons and species, born of evolution and adaptation. But now nature's timing is off.
After three decades of warming not seen in more than 1,000 years, spring arrives earlier around the world. As species shift their ranges toward the cooler poles or higher elevations, the season brings unexpected arrivals of migrating birds and mistimed hatchings of insects and flowerings of trees.
Some species on the move may flourish, but others may die. And the loss of just one kind of plant or animal, scientists say, can set off a cascade of biological events that can extinguish a whole ecosystem.

We have hundreds of species going extinct at any given time. I would say that we have quite successfully survived the passing of the dodo bird.
The author hangs herself:
"...After three decades of warming not seen in more than 1,000 years..."
So she's admitting that this also happened 1000 years ago - and yet apparently Nature survived that OK, since it's still here functioning. IOW, this warming spell should be nothing to get alarmed over.
I think the more we study Earth climate, the more we realize that it's dynamic, not static - it's ALWAYS changing!!
Hmmmmm... I bet that is that why my 2 dogs got into it with a skunk last Wednesday!
Thankfully I keep the enzyme on hand that kills the animal odors on contact.
Going to be a long spring here in Oregon.
They think the earth is warm now?
During the Cretaceous, the Antarctic was covered with pine trees, and populated by dinosaurs.
boy, Bush & Rove must have a blast with that time machine, going back 1000 years and starting global warming and all
this really isn't such a surprise coming from San Fran, I mean the whole San Fran area is full of people mixed up about how to mate
You are right on target.
You are right on target.
The dodo bird went extinct I think about 350 years ago. Soft tissue still exists. The odds of it being re-animated from the DNA are above 99%. Going extinct doesn't mean much anymore.
True. And the vernal equinox still occurs on March 20 every year. The sky is not really falling.
I wouldn't be too sure. According to the "butterfly wing" principle, that could be ultimately what cratered the Pubbies in the last election.
Dunno about who wrote this, but most caterpillars, this one included, eat leaves, not flowers. And the leaves are up way before the flowers.
It's true they will also eat flowers, but they eat many species of the carrot family, including the common weed cow parsnip, and can live perfectly well without a single flower.
The alarmists counter that the rate of change is too fast. There's little evidence to support that. CO2 increasing from 0.028% of the atmosphere to 0.038% during the last several hundred years is only detectable with precision laboratory instruments, and only by averaging thousands of readings over time to detect a slight difference. We are not close to hitting any evolution speed limit. Humans are evidence that fast rates of environmental change result in advanced genetics. In our case rapid advances in technology, culture, and tribal war fighting produced Earth's most genetically advanced and most fit to survive animal ever.
The chronicle has stories on the horrors of global warming every week or two and generally on the front page. There whole outlook is that global warming is in fact happening and it is caused by man and man alone. There is never any balance or any views representing both sides of the issue. Global warming is taken as fact.
The amount of faith required to believe in global warming makes it a cult religion. There are a remarkable number of similarities, including religious crusades, silencing critics, doomsday predictions. If you take away conventional religion from many people they are strongly drawn into a replacement.
