Disease is the bullet killing frogs, but climate change is pulling the trigger.

I suspect that climate change is involved in general in these enigmatic declines. Ultimately we have to have a transition to cleaner energy technologies, to cleaner sources of energy. But by then, it might be too late for the mountain yellow-legged frogs.

Disease is the bullet that's killing the frogs. But climate change is pulling the trigger. Global warming is wreaking havoc on amphibians, and soon will cause staggering losses of biodiversity.

The measurements show long-term trends. Glaciers react to climate change, and warmer temperatures in the Alps are reflected in the results.

If we let climate change run its course, this could be a fairly typical winter 30 or 40 years from now.

We're vulnerable to begin with, and climate change exacerbates the vulnerability.
