Iceland reports the presence of mosquitoes as climate warms

I’m surprised they didn’t already have them. They’re a plague in central and northern Alaska due to the permafrost creating standing water.

Mosquitos are adapted to long, cold winters and they're also extremely common just over the water in Greenland. Mosquitos have had literally centuries of opportunity to colonize it. They've simply failed every time.
What I've always been told is that Icelandic winter danced around the freezing point enough that mosquitos weren't able to overwinter effectively. The larvae would hatch prematurely thinking it was spring and be killed by another freeze before they could get a foothold.
That hypothesis relies on a pretty careful climatic balance though. Clearly it's hit a point where some parts of the country can now support endemic populations. My wife swears she was attacked by them when I took her to meet my grandparents a couple years ago, which I was quite resistant to believing at the time vs the similarly annoying midges. Maybe she was right?

this. i dont really believe it has to do with climate change. Is it a change in precipitation?
jazzyjackson
would a change in precipitation over historical averages not count as 'climate change' ? could we even say perhaps the whole globe is warming?

If this follows the "with vs. of COVID" thing, we're going to get "No, it's not climate change, it's change that which is climatic" here pretty soon.

"The institute noted that the mosquitoes were one of a number of new insect species discovered in Iceland in recent years."

When I was a kid in the 1980's I had a classmate from Iceland who was very smug about them not having mosquitoes there.
The Nordic varieties of mosquito are not known to carry any diseases, but the sting itches. Authorities in these countries sometimes poison wetlands where mosquito populations would otherwise grow large enough to become a public nuisance in summer.

Curious, aside from people who are immune or whatever, does any type of mosquito bite not itch?

Condolences Iceland, in the words of the late great Joe Dassin - "No me moleste mosquito, retourne chez toi"[0]

Some mosquitoes just itch way less, to the point where it isn’t really noticeable

I have no basis for this, but I think this is also based on personal genetics or similar. Most of the bites I get seem to create no bumps or itchiness at all. When i was a kid, that wasn't the same, but now in my late 30s it seems to no phase me.

LMK when it gets bad enough that you feel a mosquito biting your leg and slap it, and you end up killing twenty of the little buggers and blood all over your hand.
But seriously, mozzies suck and I hope it's not Iceland's future. On the other side of the world here, in some parts it is getting too hot and dry for much in the way of mozzies. Not sure if that is a good thing either though.

I’m sorry Iceland. :( Mosquitoes are the absolute worst. I have to cover myself in picaridin anytime I go outside in the summer where I live. I wouldn’t wish that on anyone.

This garbage article is a great example of why NPR taxpayer funding should never be restored. Ridiculous, unsubstantiated claim here. No evidence whatsoever of any link to climate change is presented. These mosquitoes came via ship and are thus like any other invasive species. Mosquitoes flourish in Siberia, Greenland, Canada, and the northernmost parts of Alaska, all places hundreds of miles north of the Arctic circle.

If you read the source article, it mentions in passing at the end that Iceland in general has seen more insects lately, partly due to climate change. It doesn't connect the mosquitos themselves to climate change. But the NPR article does indeed incorrectly connect the two. "taxpayer funding should never be restored" seems a bit of a histrionic reaction to this sloppy reporting, however.

There’s probably been a constant flow of mosquitoes to Iceland via trade for decades, but they weren’t able to establish before. You’re right though, the article could have done better showing the link.

Well obviously they didn’t spontaneously manifest there and were imported somehow. But perhaps they are gaining a foothold know when they might lot have 100 years ago?

Like Jesus before him: they hated him, for he told them the truth.

Who needs evidence when there’s a good narrative to sell? The addicted crowd will clap on cue.

Sting ?? They bite, and given a chance will engorge on one's blood. Pretty sure they came after Adam's bite, so I guess as a form of Eden-ruining punishment that makes sense.

The punishment is labour.
Climate has absolutely nothing to do with this discovery. All of the other Northern countries, many of which are colder than Iceland, already have mosquitoes (Greenland has lots of them!). Culiseta annulata is well adapted to cold climate. And it's not even particularly cold in Iceland at this time of year – the mosquitoes may not even have needed to survive a winter yet!
