I can only speculate but I wouldn't imagine global warming would have had much of an impact on global shark populations to date. Water takes a lot of energy to heat up and changes to global oceanic temperatures are less noticable than atmospheric temperatures. Sharks are cold-blooded so changes in the oceans' temperatures could potentially affect their metabolisms but I would suspect sharks would simply migrate to a more suitable area if one location became unfavourable. Most of the effects of global warming on oceanic ecosystems is through increased concentrations of CO2 in the water which can reduce the ability of invertebrate, such as corals and shellfish, to produce shells made from calcium carbonate. The main threat to shark populations is overharvesting by humans. I heard a statistic a few years ago (so don't know how correct it still is) that shark populations in the Mediterranean were ~3% of their historical size due to overfishing. I'm confident any impact of global warming is fairly irrelevant to the killing of sharks for foods such as shark fin soup.

What threats exist to shark populations and what is being done to help prevent shark populations from declining?
I THINK THE THREATS ARE NETS AND FISH HOOKS AND PEOPLE KILLING THEM

the sharks are decreasing
What changes have dolphins gone through?
dolphins have gone through lots of hard things like shark atacks, scratches on sharp coral and of coarse sometimes being hunted by people. Global Warming is also efecting the dolphins.
What can you do to protect endangered animals?
Preserve their habitats.To do this we have to:stop widespread and illegal loggingstop global warming and climate change by changing completely to renewable energy.stop trading in elephant tusks, rhino horns, shark fins, whales, etc.
What is hurting shark populations?
Humans! people eat shark fin soup and use shark products for medicines. Also many sharks are killed because of people fearing them.
Do sharks swim in Britain?
Some sharks do like the mako shark and basking shark but not sharks like the hammer head and great white and all the reef sharks however they think that many sharks like the great white as the ice caps are melting are migrating to Britain as the water is getting warmer from global warming.
Do shark populations affect other species?
Yes they keep the populations of other sea creatures in balance. Whithout them the eco would be all wrong.
