how are harp seals affected by global warming?

Climate Change Makes Life Harder for Baby Harp Seals. Warming in the North Atlantic Ocean has decreased winter sea ice and increased the death rate for baby harp seals over the past three decades, according to a new study. ... "These animals have evolved to take advantage of this ephemeral ice cover."

Ocean acidification impacts important sectors of the US economy, like fisheries and tourism, it affects food supply, and makes global warming worse by hindering the oceans' ability to absorb CO2. For communities that depend on coastal resources, their way of life and cultural identity are on the line.

Effects of Global Warming While adaptable species will survive, and other migrate, the end result will be lost biodiversity. Global warming also has potential to melt ice caps, raise sea levels and displace human populations due to coastal flooding and droughts.

The polar ice caps help keep Earth a nice temperature, but the melting of polar ice caps increases the rate of global warming. Maintaining the Earth's temperature is very important to all the organisms that live in or around the polar ice caps.

Impacts of a Changing Climate Rising global temperatures threaten human health, increase the risk of some types of extreme weather, and damage ecosystems. And as the oceans warm and polar ice caps melt, sea levels are rising, endangering coastal areas.

A warmer climate will have a major impact on the Arctic and result in major changes for plant and animal species. Melting permafrost will cause large quantities of methane and carbon dioxide to be released, boosting global temperatures already on the rise.

At the front line of climate change, the ocean, the coastlines and coastal communities are being disproportionately impacted by increasing carbon dioxide (CO2) and other greenhouse gas (GHG) emissions from human activities. The ocean plays a central role in regulating the Earth's climate.

The effects of global warming in the Arctic, or climate change in the Arctic include rising air and water temperatures, loss of sea ice, and melting of the Greenland ice sheet with a related cold temperature anomaly, observed since the 1970s.

It has a silver-gray fur covering its body, with black harp or wishbone-shaped markings dorsally. Adult harp seals grow to be 1.7 to 2.0 m (5 ft 7 in to 6 ft 7 in) long and weigh from 115 to 140 kg (254 to 309 lb).

In addition to the wildlife impacts we're already seeing, global climate change will bring another serious consequence to San Francisco Bay: sea level rise. ... This would lead to significant economic damage, and also send large amounts of toxic pollution into the Bay.

Though our planet's forests and oceans absorb greenhouse gases from the atmosphere through photosynthesis and other processes, these natural carbon sinks can't keep up with our rising emissions. The resulting buildup of greenhouse gases is causing alarmingly fast warming worldwide.

They will eat just about anything they can catch. Juveniles eat krill and other pelagic crustaceans, and the diet diversifies as they grow. Adult harp seals are eaten by killer whales and large sharks. Juveniles are eaten by polar bears and other terrestrial predators, including foxes and wolves.

Biosphere's Impact on Other Spheres This flux in methane in the atmosphere increases the amount of greenhouse gasses and leads to global warming. The biosphere impacts the atmosphere because the biological pump stores vast amounts of carbon dioxide in the oceans, decreasing atmospheric CO2 levels.

Climate change is also an issue. Scientists continue to track and compare temperature data to determine whether it has affected taiga. Warming temperatures can affect habitats, by melting permafrost areas, raising lake levels, and changing vegetation growth patterns.

In our oceans, which provide the largest natural carbon sink for greenhouse gases, plastic leaves a deadly legacy. ... As our climate changes, the planet gets hotter, the plastic breaks down into more methane and ethylene, increasing the rate of climate change, and so perpetuating the cycle.

Sudden rises in temperature and acidification can lead to the loss of marine habitats and species. Shifting ocean currents and warming waters are changing the distribution of fish stocks and altering the structure of ecosystems.
