Rana Virus Expanding with Expanding Warmth

Climate change responsible for severe infectious disease in UK frogs,
Zoological Society of London, May 9, 2019.

MAIN POINTS

UK Frogs
"Climate change has already increased the spread and severity of a fatal disease caused by Ranavirus that infects common frogs (Rana temporaria) in the UK..."

Heat-Disease Correlation
"Historic trends in mass-mortality events attributed to the disease were found to match the pattern of increased temperatures recorded over recent decades..."

More Heat-More Disease
"...disease outbreaks predicted to become more severe, more widespread and occurring over a greater proportion of the year within the next few decades, if carbon emissions continue at their current rate."

Longer Disease Season
Earlier Springs-Later Falls
"...showing that climate change could see outbreaks becoming more frequent from April to October."

Spreading with Warmth
"Up to now, Ranavirus disease has been largely restricted to England, but as average monthly temperatures increase to exceed 16°C (61°F) in more areas over longer periods, as predicted by the IPCC's high carbon-emission model, the disease is likely to spread across most of the UK in the next 50 years."

Trajectory of Doom
"...if we don't eventually slow and reverse human-driven climate change, we unfortunately can only expect things to get worse for our amphibians."

"... the disease is likely to spread across most of the UK in the next 50 years."

Support Tahoe to Whitney

The Tahoe to Whitney Trail Guide and Magazine are walked, written, funded, and supported by my efforts, with the help of kindred spirits and my sister.

We offer valuable Trail Guide, Skills, Weather, News and Analysis.

My goal is to get you out to see your natural and social potential. Help me keep this unique resource accessible and expanding towards its potential. We've a lot of miles to cover ahead...

I NEED HELP!
If you feel these efforts are valuable, I'm cordially inviting you to support them, here:

 

 

I am currently working towards publishing the completed guide between Tahoe & Yosemite as an e-book, while converting this "blog" to a fine magazine format. You will like the results! Help Tahoe to Whitney reach its potential!
