That form of migration is happening all over the world right now.
Virginia opossums, traditionally associated with the deep south, are now routinely spotted around Toronto, and are moving even further north. Armadillos, though still shy of the Canadian border, have crossed the Ohio River. American alligators, long stopped around Cape Hatteras, are now spotted in the tidal creeks of Virginia’s Eastern Shore. [1] Lobsters are moving north to the Canadian Maritimes from New England, and the blue crabs of Chesapeake Bay are filling the niches they're leaving behind.
It's much the same way in Europe. The European praying mantis used to be a hot-climate central Italian and Balkan insect. Now it's routinely spotted in Germany, has been found as far north as Latvia, and I found one in the usually-chilly Slovenian mountains just the other day!
Wherever you are on the map, look at the climate and ecosystem a few hundred miles south. That's likely where things are heading for you; it's a safe bet that the species that thrive there are the ones that are going to be best adapted to where you live in the second half of the 21st century.
Not doubting all this, but the possum thing is interesting.
They were in southern ontario in my youth in essex county ( late 80s ). And google says they were reports as far back as the 60s of scattered sightings.
But not all species are mobile enough, and up north the winters are darker and the summers are lighter.
The shift will be incomplete, other species just go extinct.

There was a vaccine developed for Lyme disease in the early 2000's. It was canned because the market wasn't believed to be favorable. Lyme disease is an awful illness that often progresses to chronic and incurable.
Tick populations have exploded recently with our new warmer climates, and now a new vaccine is slated to enter the market in the next few years.
Unfortunately however the vaccine will not protect against lone star tick bites, which can make you allergic to red meat.

The context on this site is often assumed to be American. I consider myself to be multicultural and I'm definitely guilty of that in some of my posts.
There's a lot of misinformation and conspiracy theories about vaccines in the USA in addition to the valid questions which are equally serious. The Centers for Disease Control (CDC) is currently run by an individual who has superstitions about them, and is actively dismantling the professional efforts which further vaccination. Even if there was a vaccine available on the medical market in the US, because that is what we have in this country, a market for medical care, it's not clear that it would be accessible to everybody or the people who need it. The reason for this is because Americans do not have universal healthcare, and in fact, the President has recently enacted a law that cuts public healthcare for many millions of Americans, which would provide such a vaccine.

I'm aware of the post-COVID vaccine hesitancy (this is definitely not limited to the US) but the vaccine the CDC is talking about was discontinued "citing insufficient consumer demand" in 2002, over 2 decades ago.

In this case, what they're doing is clearly going beyond their lawn and negatively impacting you.
It's weird to suggest that "spraying poison on your neighbors" is deemed acceptable, as long as you're standing on your own property when you do it. If they were standing on their lawn throwing rocks at your apple trees, or shooting a gun at your apples, we wouldn't say they're free to do whatever they like. Heck, we don't even let people play loud music if it disturbs their neighbors.
We really need to update our mental models of harm and violence to account for modern possibilities. We should treat harm from pollution exactly as seriously as we treat harm from projectiles. Dying from cancer from your neighbors incidental pollution is just as bad as dying from a bullet from your neighbors errant gunshot.

I think the issue is for the animals that actually need a colder climate and/or rely on ice/snow cover - a warming world won't give them a new space to move to (yet).
giarc 4 hours ago [-]
One anecdote/example that has stuck with me is a heard of caribou in the Canadian north. In winter, they typically dig through the snow to find plants to eat. One year, with rising temperatures, a large area was left with a thick layer of ice on top of the snow. Precipitation was falling as rain (instead of snow) due to warmer temperatures, then freezing overnight creating this thick layer of ice. The caribou couldn't punch through the ice and ended up starving to death resulting in a mass die off.

The ones that survived will have had more efficient metabolisms, or harder hooves that could break through the ice to get to the food, or could have learned a technique to cope. Hopefully their next generation will retain those traits or that culture to adapt.

Greenhouse gas emissions have been rising to fuel growth that allows billions of people to achieve a quality of life that we would consider basic. Meanwhile, America's greenhouse gas emissions are below what they were 30 years ago. On a per-capita basis, they are over 25% lower.

Current Mediterranean water temps are +6C above normal, as observed over peak human civilization in the 20th century. That is 6kWh per cubic meter, in just the Mediterranean. The article briefly mentions this extending 30m down.
To give the order of magnitude of the energy involved, the Mediterranean surface area is 2,500,000,000,000 sq m. At 6kWh cu m and 18m deep, that is the energy equivalent of about 390,000 megatons. Or about 8,000 Tsar Bombas. The Mediterranean is small, about 0.7% of ocean surface area.
bondarchuk 1 hours ago [-]
I still have no clue at all how much a Tsar Bomba is in the context of the climate.
grues-dinner 49 minutes ago [-]
1 Tsar Bomba (50 MT = 2e17J) is about 1/28,000,000 of the total solar power delivered to Earth annually, so about 1.4 seconds of top-of-atmosphere solar power (~1.5 million PWh / year).
On the other hand, it roughly equals 1/2000 to 1/3000 of annual global energy consumption (~175 PWh / year) so about 4 hours of human energy.
The energy of those 8000 Tsar Bombas in the Mediterranean then is the same as all of human energy, electrical and fossil and otherwise, going to heating up that sea for a little over 2 years straight, or focussing all sunlight over the disc of the Earth on it for 3 hours.
(All these figures depend on who you ask as all the figures are a little bit fuzzy).
It also shows that any key to climate change revolves around adjusting the modulation of insolation and/or retention - the actual energy used by humans is, for the forseeable future, completely irrelevant except on local scales like warm water outflows into rivers and seas.
throwaway5752 33 minutes ago [-]
Plants and any organisms in photosynthesis-dependent food chains may have issues with modifying the degree of insolation.
Also, again, the Mediterranian is 1/100-1/200th of global ocean surface area. And we have melted a lot of ice cap/glacier mass. The latent heat of fusion of water is very large, also.
Long term, insolation and retention are important, but short term we are reaching the limits of the "Free Ride" portion of climate change where energy sinks absorb the additional delta created by the CO2 induced greenhouse effect.
edit: the tsar bomba was to try to make it tangible, as people don't understand these orders of magnitudes well.
grues-dinner 5 minutes ago [-]
The point is not that "we're not fucked" (we probably are pretty fucked). Just that Tsar Bomba yield, like basically any amount of energy directly generated by human endeavour, is a pretty irrelevant unit of energy when talking about the climate because they are on a completely different scale.

On the other hand, it roughly equals 1/2000 to 1/3000 of annual global energy consumption (~175 PWh / year) so about 4 hours of human energy.
The energy of those 8000 Tsar Bombas in the Mediterranean then is the same as all of human energy, electrical and fossil and otherwise, going to heating up that sea for a little over 2 years straight, or focussing all sunlight over the disc of the Earth on it for 3 hours.
(All these figures depend on who you ask as all the figures are a little bit fuzzy).
It also shows that any key to climate change revolves around adjusting the modulation of insolation and/or retention - the actual energy used by humans is, for the forseeable future, completely irrelevant except on local scales like warm water outflows into rivers and seas.
Also, again, the Mediterranian is 1/100-1/200th of global ocean surface area. And we have melted a lot of ice cap/glacier mass. The latent heat of fusion of water is very large, also.
Long term, insolation and retention are important, but short term we are reaching the limits of the "Free Ride" portion of climate change where energy sinks absorb the additional delta created by the CO2 induced greenhouse effect.
edit: the tsar bomba was to try to make it tangible, as people don't understand these orders of magnitudes well.
