Climate change has had a profound effect on the Earth's weather. By Mark McCormick. Together we can make the world's oceans safe for whales. And many species that depend on ocean currents for reproduction and nutrients will be affected. By Mark McCormick. A 18-meter-long sperm whale swims in the Mediterranean sea, off the coast of Nice, France, July 22, 2009. How Whales Can Help Us Change the World’s Climate for the Better 5 years ago. Climate change will likely be one of the main drivers of extinction in the 21st century because of the speed at which average temperatures are warming—faster than at any time in the last 15,000 years. Species are at risk of extinction Wild orcas may not survive climate change If Chinook salmon populations continue to dwindle, killer whales could be driven to extinction-- Let’s take a look at five ways orcas are threatened in the wild. For example, many reef-building coral and reef fish species rely on … The current topic in regards to climate change is that of ocean acidification. Climate change is affecting humans and animals alike, including orcas. Changes in temperature, freshening of seawater, acidification, sea level rise, loss of icy habitats and the decline of food sources are just some of the threats posed by climate change. How Whales Can Help Us Change the World’s Climate for the Better 5 years ago. Climate change, depletion in the ozone layer and the related rise in UV radiation may also lead to a fall in the population of krill, a primary food source for many marine species. * 97% of active climate scientists agree that today's climate change is caused by human activities . As mentioned earlier, many marine species’ migratory patterns can change as the currents they follow are altered. One of the most impacted populations by climate change are pollinators who are facing unprecedented difficulties as they struggle to survive. Climate change will likely be one of the main drivers of extinction in the 21st century because of the speed at which average temperatures are warming—faster than at any time in the last 15,000 years. Climate change, an indisputable, human-induced phenomenon, is altering the environment at unprecedented levels. Climate Change. * 97% of active climate scientists agree that today's climate change is caused by human activities . Many of them see the orcas as a threat because they have learned to steal the fish from them. What Antarctic Killer Whales Can Teach Humans About Climate Change The giant mammals are extremely vulnerable to changes in the ecosystem, making their health a … Climate Change Changes in temperature, freshening of seawater, acidification, sea level rise, loss of icy habitats and the decline of food sources are just some of the threats posed by climate change. For example, fishermen in Brazil say that killer whales are able to consume 50 percent or more of the swordfish catch. Although some choose to implement inoffensive actions to deter killer whales, others with less patience can shoot them. In Antarctica, climate change is having a range of impacts, from ocean acidification (which is more pronounced in colder waters) to warming temperatures (the Western Antarctic Peninsula is one of the fastest warming places on the planet), and loss of sea ice. Climate change is affecting the chemistry of seawater The same burning of fossil fuels that increases greenhouse gas levels in the atmosphere, is also altering the chemical composition of … The effects are already being felt around the world and on the islands. Species are at risk of extinction Sea creatures like whales have a clear impact on the pace of climate change. Climate change has impacted the natural rhythms of weather, the behavior of animals, and the blooming of flowers. Without dramatic changes to our government policies and lifestyles, the world’s environment, economy, and people will face ever-increasing challenges. Climate-change.
