A once rare butterfly living in the United Kingdom is the latest unexpected beneficiary of the rising temperatures brought about by global climate change. Over the last 25 years, the brown Argus butterfly can now exist over a larger range thanks to a warmer environment and a new plant host to raise its young. And these fortunate insects aren't the only ones who stand to benefit from a warmer world. Yes, over the coming decades, there are certainly many other species, including humans, that will feel increasingly pressured by environmental changes brought about by climate change. But there will be some balance of winners and losers among the different species on this planet. Here's a look at some of those who will likely come out ahead.
Change in wind patterns as a result of climate change has helped albatrosses in the Southern Ocean find food more rapidly, according to a study published in a January 2012 issue of Science. The faster and more intense winds reduce the amount of energy albatrosses need to expend to fly, particularly useful given that these birds can fly distances spanning thousands of miles. By using less energy and finding more food, the albatrosses are healthier and often have better breeding outcomes, according to the study's authors.
Gray Nurse Shark
Worldwide, around one third of oceanic shark species are at risk of extinction, according to the International Union for the Conservation of Nature (IUCN). These animals are primarily at risk as a result of human intervention, particularly the overfishing of sharks for their fins. But there is one species of shark that may stand to benefit from man-made climate change, the Australian gray nurse shark. Like many shark species, gray nurse shark populations have been under pressure. This species could disappear entirely by 2050. However, thanks for warmer waters surrounding Australia, two separate populations of this nurse shark on each side of the continent may reunite for the first time in 100,000 years.
Sharks aren't the only sea life that might benefit from warmer waters. Killer whales, too, appear poised to take advantage of rising ocean temperatures, exploiting new feeding areas as Arctic snow ice melts that were once off limits. The orca's gain, however, could be detrimental to other species. Killer whales prey on two species, the beluga and the narwhale, considered "near threatened" by the IUCN. With their chances to escape to safety from the predatory killer whales dwindling as ice melts, these species could face further pressure to their populations.
This tiny insect has made major inroads into the North American continent thanks to warmer temperatures. Mountain pine beetles can decimate entire forests. During cold snaps, they are killed off. But with shorter, warmer winters, more of these bugs are surviving through the cold season and expanding their ranges even further.
Acidifying oceans and warmer waters might be encouraging swells in populations of jellyfish around the world. Although the notion that jellyfish are benefiting from climate change has been subject to debate, studies have shown that coastal jellyfish populations are generally on the rise. More jellyfish would be bad news for any species that relied on the oceans for its food supply, including humans. Jellyfish can essentially reorder the food web by eating the same plankton that would otherwise be consumed by fish, restricting the transfer of energy on the food chain since predators tend to avoid them. The increase in jellyfish populations could also lead to an ecological disaster by resulting in an increase in carbon beyond what oceans can cope with, according to a report from The Guardian. When jellyfish die, they break down into biomass with considerably higher levels of carbon than their vertebrate counterparts. Bacteria that thrive on decaying organisms cannot absorb carbon as well and instead breathe it out into the atmosphere as carbon dioxide.

Once standing on the brink of extinction due to over-hunting for their meat and feathers in the 19th century, trumpeter swans have made a comeback in Alaska, thanks not only to restrictions on hunting these birds but also to global warming. Warmer temperatures have allowed the swans to expanding their ranges, and longer summers have allowed to greater opportunities for breeding and raising young, according to Scientific American.
Americans spend some $40 billion a year caring for their lawn, according to Bloomberg News. And that industry could get even more lucrative with the spread of a pest that has its sites set on your home turf: fire ants. According to a report from the National Wildfire Foundation, the range of red imported fire ants could expand some 21 percent in the United States, more than 80 miles northward, within the lifetime of a child born today.
If there's one creature who's climate change gain is our loss, it's mosquitoes. No longer restricted to strictly tropical environments, mosquitoes have spread as warmer temperatures have crept into environments they had never previously been. More mosquitoes means higher potential to spread diseases, including malaria, West Nile virus and dengue fever. This greater risk of disease is not only bad news for humans, but also some animals, including certain bird species, who had previously been unexposed to these pests. In fact, even some of the world's largest creatures are not immune to the disease transmitted by these tiny insects. Last month, the Whale and Dolphin Conservation Society revealed that two whales kept in captivity died as a result of diseases carried by mosquitoes.
Yellow Bellied Marmot
Although most mammals won't be able to flee climate change quickly enough, some are taking full advantage of the changing conditions. The yellow-bellied marmot, which calls Colorado's Rocky Mountains home, fattens up ahead of winter before its long hibernation into spring. With a shorter season though, the marmots are emerging larger than they otherwise would. As a result, they've also been breeding more and passing their larger size onto their offspring.
Politicians who oppose taking action on climate change or discount the whole matter could be risking their careers.
Public opinion in the United States has shifted in favor of doing something about climate change, and politicians who want to get elected need to take note of it, according to a new study by the Yale Project on Climate Change Communication.
A nationwide survey conducted before the November election found that concern about the effects of global warming is high across political groups, with most Democrats and Independents expressing concern about global warming and its potential harm for people today as well as to future generations. A clear majority of registered voters, 58 percent, said they would consider a candidate's position on global warming when deciding how they will vote.
Most Republicans get the message as well, with 52 percent saying that global warming should be a priority for the President and Congress. In fact, only 2 percent of Democratic voters, 10 percent of Independent voters and 28 percent of Republican voters say the United States should make no effort to reduce global warming.
"We have a whole series of questions we ask again and again and track over time," said Anthony Leiserowitz, director of the Yale project, which polls the same approximately 1,000 people, year in and year out, to get a view of how public opinion changes over time.
Pollsters and statisticians agree that 400 is the minimum survey size for getting a representation of U.S. public opinion, with an accuracy of plus or minus 5 percent. The Yale project uses a pool of 1,000 randomly selected Americans so that they can study sub-groups -- like Democrats, Independents and Republicans -- and still get statistically meaningful results.

For politicians of either party thirsting for the Independent vote, favoring action on climate change would appear to be a good idea, Leiserowitz explained. Only 3 percent of Independents do not believe that climate change is happening, with fully 43 percent say they will vote based on the issue. The remaining 54 percent are unsure or won't base their vote on the issue.
That compares with 9 percent of Republicans who said don't believe global warming is happening or vote accordingly, a whopping 68 percent of Republicans who are not sure, and 24 percent who believe global warming is real.
Among the politicians probably benefiting from public opinion is Governor Jay Inslee of Washington. Inslee was elected while being conspicuously vocal about climate change and even coauthoring a book on the promise of clean energy.
"Every ton of coal that is burned anywhere on the planet Earth ends up in Puget Sound," said Gov. Inslee at a recent meeting with the press in Olympia, Wash. When asked about the negative effects of ocean acidification -- caused by the burning of fossil fuels worldwide -- to the state's shellfish industry, he said, "This is not only about the polar bears. It is about business opportunities in our state that are today being damaged."
The survey also underscores the large segment of people still on the fence about climate change, which is a matter of concern, said Mark McCaffrey, who works on climate change policy matters for the Nation Center for Science Education.
"The thing that really pops out at us is the fact that people are not understanding the basics," McCaffrey said. "This points to the need for a national effort to educate people."
