Warming could spur "evolution explosion": study (fast-growing weeds evolve/adapt to climate change)

But some long-lived species -- like the venerated California redwood tree, with a life-span of hundreds of years -- will not have the capacity to adapt so quickly, because their life cycles are so long,

True.  But it's unlikely the climate in northern California could get hot fast enough to kill them anytime soon.  

If the weather changed enough to stop the regular fogs though, those forests would be toast in short order.

I don't know what kind of temperature change that would take.  It's more likely that a permanent shift in the currents off southern Oregon and northern California would do it.

Wow. That's just....sad. What a pathetic perspective you have.

Well, guess what, Weis Guy? The current CO² increase is expected to last only for a couple of hundred years more. With their lifespans of 'hundreds of years, there's every reason to expect the redwood forests to weather any relatively transient climatic changes due to atmospheric CO² concentrations just fine.

Oops. That's CO₂.

Are you serious? Because I wasn't.

"climate change"

Your response reflects too much thinking and logic. You will never be a liberal. (smirk) Actually I've always been perplexed at the libs perpetual whine of disaster due to climate change. They never see any possible positive happenings (like expanded areas of agricultural growth) that would occur due to global warming. With the leftists there can be nothing but disaster from g-w. By leftist logic then global cooling, even leading up to another ice age, would be a positive thing.

[Northern Yankee]

Sounds like a good idea to me.

People tend to forget that trees are a renewable resource.

How many climate change cycles have the giant redwood trees adapted to already?

I predict the giant redwoods will be destroyed by wildfires, and not by climate changes, because of the environmentalist continued blocking of forest harvesting and resource management by logging industry.

[Northern Yankee]

Exactly!

When you think how long the redwoods have been around, its folly to predict they are going to meet their demise real soon.

[Tolerance Sucks Rocks]

Just wait. If the globe started into a long-term cooling trend (on the scale of decades), people would be barking about the coming ice age.
