Climate change is already happening too fast...

Animals failing to adapt to speed of climate crisis, study finds

Scientists warn of ‘alarming’ lag between human-driven seasons shift and animals’ behavioural changes


The speed of climate disruption is outstripping many animals’ capacity to adapt, according to a study that warns of a growing threat to even common species such as sparrows, magpies and deer.

Scientists behind the research described the results as alarming because they showed a dangerous lag between a human-driven shift in the seasons and behavioural changes in the natural world.

Previous academic work has shown that species respond to warming temperatures by earlier timing of biological events, for example egg-laying by birds, budding of plants and flying of insects. The new meta-study, published in Nature Research, examines how effective this is in terms of reproduction and survival.

Based on 10,090 abstracts and extracted data from 71 published studies, it found a clear lag in the majority of species studied and none could be considered safe. “The probability that none of the study species is at risk is virtually zero,” the paper notes.

The authors said hundreds of thousands of species were not covered by their study, which was weighted heavily towards birds in the northern hemisphere, but they said the problems of adaptation to climate change were likely to be even greater for other animals already deemed at risk of extinction.

Viktoriia Radchuk of the Leibniz Institute for Zoo and Wildlife Research in Germany, said: “Personally I find the results alarming. Species attempt to adapt to changing environment, but they cannot do it at a sufficient pace to ensure that populations are viable. Climate change has caused irreversible damage to our biodiversity already, as evidenced by the findings of this study. The fact that species struggle to adapt to the current rate of climate change means we have to take action immediately in order to at least halt or decrease the rate.”

Fungi are adapting:

Research argues that deadly Candida auris "may be the first example of a new fungal disease emerging from climate change.

the concept of cascading tipping points not only applies to climate sensitivity but also to coming potential society instabilities, as discussed in the linked article:

Lost Cities and Climate Change

by Kate Marvel (2019)

https://blogs.scientificamerican.com/ho ... ;text=Lost

… the adversity brought by climate change caused societies to break apart, magnified pre-existing divisions, and made desperate people easy prey for dangerous people.

“The climate has changed before,” say people who want to minimize the scale of the current challenge. I have never understood how anyone could find this comforting. The natural climate changes that have shaped human history have almost always been smaller and more regionally contained than the large-scale human-caused change we are currently experiencing. And even these changes have provoked suffering, scapegoating, and the collapse of civilizations.

I am often asked what frightens me most about climate change, whether I lie awake at night thinking about ocean hypoxia or arctic permafrost or other feedback processes that could turn a bad thing into a catastrophe. I am scared of the physical changes that await us on a warming planet, but the most important feedback process is the least well understood. The scariest thing about climate change is what it will make us do to each other.

While we're talking about agriculture, I found this:

Dicamba revisited: Will corn be the next herbicide debacle?
https://thefern.org/ag_insider/dicamba-revisited-will-corn-face-the-same-damage-as-soybeans/

Somehow, Dicamba (Round-up, I think) is able to spread very easily geographically. Does the weather affect this? Heat and evaporation? Possibly.

Why NOTHING will be done to avert rapid climate change:

Basically it requires a new mindset other than: me, me, I want it NOW, of Western Civilization. It goes against our social DNA. It cannot be rewired in just the few generations that we have had since being warned.

Why nothing can be done to avert climate change. Welcome to a glimpse of the Plutocene - what follows our Anthropocene (or just replaces the name, as it is happening so quickly).

"Hope, I try to avoid it like the plague!"

"We live in a futuristic bubble."

"Get out the champagne for everything we've enjoyed!"

Well, the last is my own sentiment.

Planning for global warming:

1. Acquire lawn chair.
2. Lay in supply of popcorn and beer.
3. Identify a location for lawn chair with a good view of the action.
4. Watch the fur fly.

Oh, I never forget.

Think of the humor as whistling past the graveyard ... although I'm still hopeful that they'll be able to keep the lights on and the convenience stores full of cheese doodles until I'm safely in the grave.

And the truly terrifying thing ... population is still going up, energy consumption is still going up. We haven't even reached the start of the downslope yet.
