Default The Arctic has become warmer by 5 degrees. Australia has snowed.

The Arctic has become warmer by 5 degrees. Australia has snowed. German entomologists have found evidence of the beginning of mass extinction, which could be the largest environmental disaster since the extinction of the dinosaurs.

According to scientists, insects, which make up two-thirds of the species diversity of animals, die at an alarming rate, which will lead to disastrous consequences for food chains and ecosystems. This conclusion was reached by experts on the basis of the results of the selection of more than 80 million arthropod specimens, which took place over about 30 years. Insects gathered using traps in 63 places along the banks of the Rhine.

It turned out that over the entire observation period since 1994, the total biomass of insects fell by 76 percent. Arthropods are food for birds, whose populations are also declining. Researchers believe that Western Europe may soon pass the “point of no return” due to a critical reduction in biodiversity, after which natural ecosystems will never recover.
The abundance of large freshwater fish, whose mass exceeds 30 kilograms, has also declined by 94% over the past two decades.

Unfortunately that gels nicely with my own, anecdotal, experience.

In my youth when we travelled by car at night through the countryside you had to use the wipers regularly to get the insects off the windscreen.
Now 30 years later I hardly ever get any insects splat on the screen.

Worrying indeed...

Ah, well we had a good run, and the Earth has recovered from numerous major climate changes and mass extinctions - it is kinda “her” thing.
My money is on tardigrades the next time around. There’s a concrete goal for the next manned lunar mission- check for signs of life at the recent Israeli “landing” site.

I thought this too. I thought maybe it was the result of advancements in aerodynamics and car design, increased windscreen rake and improved slipstreams carrying them over the car, but there is a whole field of research based on it.

I use a different metric - things that sting me, and things that bite me, when I am doing my outdoor tasks.

I do not detect any fall off of stings or bites.

Yes, there were many insects, including bloodsucking, and they annoyed. There were many mosquitoes until the early 2000s. Cockroaches are now completely gone. Under the blow of a bee. But I often see dragonflies in the city, and this is a very good sign. But blood-sucking ticks have spread all over the world. As a teenager in the mid-80s, I often caught spinning huge pikes weighing 8-10 kg on the Volga. And now almost no one catches fish on the Volga, apparently it is almost there. Perhaps there are still many fish only at the mouth of the Volga, where the river flows into the Caspian Sea.

That is so upsetting. What is the point of living in a nice neighbourhood then?

We have mosquitos so big they should be assigned transponder codes. In my misspent youth, I spent a night in a trailer, in a rice field, after a Who concert in Memphis, TN - you could hear the mosquitos banging on the side of the trailer trying to get in.

Sorry you guys in Europe are running out of bugs - come get some of ours. I'm getting ready to go mow about three acres. Since this will be late afternoon, I'll get both the stingers ( day time ) and the biters ( twilight and night ).

Y'all help yourself to some of our ticks, deer, and wild hogs while you are here.

Three acres is about 1.2 hectares. I can reassure you around the Dallas-Fort Worth area, Texas, USA there ARE plenty of cockroaches. I used to live in a really cockroach infested apartment, and my cat brings in snakes, lizzards, and cockroaches on a regular basis.
