Climate Change Could Wipe Out a Third of Parasite Species, Study Finds (nytimes.com)
An anonymous reader quotes a report from The New York Times (Warning: source may be paywalled, alternative source): Recently, scientists carried out the first large-scale study of what climate change may do to the world's much-loathed parasites. The team came to a startling conclusion: as many as one in three parasite species may face extinction in the next century. As global warming raises the planet's temperature, the researchers found, many species will lose territory in which to survive. Some of their hosts will be lost, too. Researchers have begun carefully studying the roles that parasites play. They make up the majority of the biomass in some ecosystems, outweighing predators sharing their environments by a factor of 20 to 1. For decades, scientists who studied food webs drew lines between species -- between wildebeest and the grass they grazed on, for example, and between the wildebeest and the lions that ate them. In a major oversight, they didn't factor in the extent to which parasites feed on hosts. As it turns out, as much as 80 percent of the lines in a given food web are links to parasites. They are big players in the food supply.
Some researchers had already investigated the fate of a few parasite species, but Colin J. Carlson, lead author of the study and a graduate student at the University of California, Berkeley, and his colleagues wanted to get a global view of the impact of climate change. Some kinds won't lose much in a warming world, the study found. For instance, thorny-headed worms are likely to be protected because their hosts, fish and birds, are common and widespread. But other types, such as fleas and tapeworms, may not be able to tolerate much change in temperature; many others infect only hosts that are facing extinction, as well. In all, roughly 30 percent of parasitic species could disappear, Mr. Carlson concluded. The impact of climate change will be as great or greater for these species as for any others studied so far. The study has been published in Science Advances.

So, once chance in three we get rid of the lawyers?
Could be worth it then.
Any of them?
While we're on the topic, a new study just came outhttp://dailycaller.com/2017/06...">fully admitting the models are wrong. They've over-predicted the amount of warming we've seen, compared to reality. Here's a link to the paper.
So it's reasonable to assume that the worst predictions from AGW are not going to happen.

I am ashamed of what Conservatism has become, as a human being, part of a web of life on this 1 planet that we know of with any life at all.
So this is why liberals are always against climate change. A third of them could die from it!
I agree completely...except for mosquitos and cockroaches, fuck those guys.
One of the parasites has already disappeared:

You are welcome on my lawn.
Cockroaches and mosquitoes are food for the things that the things that you eat, eat. Well, it's complicated. The point is nobody eats without everybody eating.
Except the fungii that will own the entire doomed planet long after we're gone, they will do whatever the hell they want.

Do Humans count as parasites? Maybe humans will be wiped out.

We are doing alright without Variola major .
What about these parasites that nest in children eyes and make them blind?
Or all the other horrible ones you don't know about?
It might wipe out roughly 1/3 of hosts also, so it would generally "balance" out.

Fleas? I don't think so.
Maybe specific fleas finely tuned to a particular animal.
But fleas in general?
My experience with climate change over the last 30 years is more bugs, more parasites, more diseases reaching in to my area from down south than used to.

There are lots of species I'll try to save. Intestinal worms are not one of them.
Oh, that's a shame

Are climate alarmists so afraid to have an actual discussion that they must denounce anyone who disagrees as a troll?
Thank you, Bradley Manning, Edward Snowden and so many others, for courageously defending humanity, my freedom and more!

We seem to do OK without smallpox.
At least you're not denying that it's happening.
If you could understand even just the summary, you'd know parasites play a big role in the food chain. So it's not an unequivocal good thing.
Maybe it's time you stop getting your news from headlines.
Those who do not learn from commit history are doomed to regress it.
Not really, have you seen how many humans there are now?
If you eliminate one predator species, their prey will multiply uncontrollably.

Only because they're not fluffy. Specist!

Bad? Hell no. It's one of the best things that happened to the Earth in its more recent history. Finally it can return to the state it was in a couple million years ago when it was warmer on this planet, with a higher CO2 concentration that made those wonderful, huge forests possible that could be found all over the place. We might even see those deserts vanish (yes, despite warmer climate, it will probably also be more humid and generally more beneficial for plant growth).
Ok, we won't see it. But maybe if there is some more intelligent life in this universe that makes experiments like this with some planet other than their own might.
We used to have a Bill of Rights. Now, with the rights gone, all we have left is the bill.
Oh no! Whatever will we do without fleas riding pets into our homes and forcing us to fumigate? Hartz could go out of business!
Here it's not a problem with people being killed by something or someone but more one of people not being born. This is mostly due to people noticing troubling times ahead and refusing to propagate. Something you can observe in a few species that do not have young if it's likely that there will not be enough food for them to survive.

Indeed. Problem is that that re-balancing act might take millions of years and involve getting humans out of the equation.
What many climate change critics and proponents get wrong is that environmentalism is about saving "nature" or the planet, but really it isn't. The planet doesn't care and will be just fine. Ten million years are nothing on a planetary scale and life will adapt to our pollution and destruction and go on even without us.
What this is about is conserving the fragile ecosystem that humans managed to evolve and thrive in. We are not so resilient.
Mosquitoes do not make up a substantial part of any creatures diet. Even bats do not depend on mosquitoes. Bats eat beetles, wasps, and moths. Mosquitoes make up less than 1 percent of their total diet.
Studies of areas where mosquitoes have been eliminated show no major ecological disruption. They are seasonal anyway. Mosquitoes (at least the ones that harm us) are a blight on the world and should be eliminated.
Please, Tell me more about the extinction of fleas. I want to know if there are any downsides to this. Can we mitigate those?
Can we get Ticks on the list too?

We can do without humans. Frankly speaking, we can do without any particular species. Life will re-balance, it always has.
And who exactly is this "we"?
What usually happens when one species is diminished is that another species takes its place.
So, we may not get fewer parasites, only fewer species of parasites.
Overall, when the Earth gets warmer, species from places that were warmer are likely to become more common in places that used to be colder, but now are not. That's not just parasites, but all types of insects, plants, animals and diseases.

Who wold have thought, then when the dodo died out, its parasites died out too.
So either I change my ways and save the mosquitos and evil spouses or a big chunk of the world dies, coastlands reduce, and we all have to disgusting lab grown algae.... how long do I have to think about it?
Now I itch all over . . .

As mentioned elsewhere, Forbes' claim that states with the lowest wages, the worst life expectancy, the worst education, the worst health care and the worst you-name-it are "better off" because the cost of living is sometimes a hair lower is both ridiculous and amusing.
