Global warming benefits once-rare butterfly

WASHINGTON - Global warming is rescuing the once-rare brown Argus butterfly, scientists say.

Man-made climate is threatening the existence of many species, such as the giant polar bear. But in the case of the small drab British butterfly, it took a species in trouble and made it thrive.

It is all about food. Over about 25 years, the butterfly went from in trouble to pushing north in Britain where it found a veritable banquet. Now the butterfly lives in twice as large an area as it once did and is not near threatened, according to a study in today's issue of the journal Science.

Decades ago, the brown Argus "was sort of a special butterfly that you would have to go to a special place to see and now it's a butterfly you can see in regular farmland or all over the place," said study co-author Richard Fox, an ecologist at Butterfly Conservation, a science and advocacy group in the United Kingdom.

Global warming helping the brown Argus is unusual compared to other species and that's why scientists are studying it more, said study co-author Jane Hill, a professor of ecology at the University of York.

Biologists expect climate change to create winners and losers in species. Stanford University biologist Terry Root, who was not part of this study, estimated that for every winner like the brown Argus there are three loser species, like the cuckoo bird in Europe. Dr Hill agreed that it is probably a three-to-one ratio of climate change losers to winners.

As the world warms, the key interactions between species break down because the predator and prey may not change habitats at the same time, meaning some species will move north to cooler climes and will not find enough to eat, Dr Root said.

"There are just so many species that are going to go extinct," Dr Root said.

What makes the brown Argus different is that it found something new to eat, something even better than its old food, the less common rockrose plant, Dr Hill said. The new food is a geranium and it is more widespread.

"It's almost like the whole of the buffet is now open to it," Dr Hill said. AP

No, they die as soon as they step in the water. It's a fact. Check google.

In the meantime, this butterfly is doing quite well.

So much for those alarmists, eh?

The boys at goose lake Nunavut sent me pics of Mallards in the lake,they did not know what they are as they have never seen them that far north.Kind of neat how that global warming works.

Indeed.

Accepting it exists is the first step.

I dont know any geologist that will dispute the fact the climate changes and has been and allways will be changing.

Well at least you're not crazy, like Ezra Levant.

Many years in the strip mine,I saw about 500 million years of sedimentary layers with my own eyes.

It's true, there are both natural and human-related factors at hand.

Exactly. The Climate will change no matter how much money exchanges hands.

If you're talking about natural climate factors, yes, they will always exist.

Some people are silly enough to believe the latter has more effect than the former.

A majority of scientists, yes.

When it comes to climate science, I'll listen to the experience of climate scientists.

Regardless of what I want to hear, they all say the same thing.

Quote:

A survey of all peer-reviewed abstracts on the subject 'global climate change' shows that not a single paper rejected the consensus position that global warming is man caused.

Quote:

Subsequent research has confirmed this result. A survey of 3146 earth scientists asked the question "Do you think human activity is a significant contributing factor in changing mean global temperatures?" ( Doran 2009 ). More than 90% of participants had Ph.D.s, and 7% had master’s degrees. Overall, 82% of the scientists answered yes. However, what are most interesting are responses compared to the level of expertise in climate science. Of scientists who were non-climatologists and didn't publish research, 77% answered yes. In contrast, 97.5% of climatologists who actively publish research on climate change responded yes.

I think most geologists are about as close as you can get when it comes to environmental science,sedimentary layers dont lie(pun) and reading them is not rocket science either.

I wouldn't make an assumption about global warming based on sedimentary rock.

You have not worked with any climate scientists and I think you are mistaking a few field geologists for scientists.

As mentalfloss posts later, there are no contradictory science studie. The verdict is unanimous that the warming is occurring faster than at any time in the history of the Planet and that the warming of the past several decades is entirely anthropogenic. There are natural variations within the warming but they happen in both directions. The trend is exclusively from human factors.

This is quintessentially, the correct position on the matter.

The only real disagreement is in the degree of effect and scope of AGW.

If present trends continue, the world will be about four degrees colder for the global mean temperature in 1990, but eleven degrees colder by the year 2000. … This is about twice what it would take to put us in an ice age.

Thats real funny because I never said that,of course its warming and cooling.
What else is new?
