6 Ways Climate Change is Impacting Animals

1. Clownfish are Going Deaf

The adorable reef-dwellers that served as inspiration for Disney’s Nemo are losing their hearing due to ocean acidification. This means that the fish are suddenly less able to respond to the presence of predators, threatening their survival.

2. Evolution Could Go Wild

The conventional wisdom is that evolution happens slowly, over the course of a great many generations. Some new research, however, suggests that faced with rapidly changing environments due to climate change, plant and animal species may be able to kick adaptations into high gear. More research is needed, though some scientists have already witnessed evolutionary changes in select species happening at an accelerated rate.

3. Coral Stops Growing

Coral — the foundation of the “rainforest of the ocean”—responds directly to increases in temperature, according to research. Unfortunately, this response is largely negative, with growth rates slowing to a near standstill.

4. Bird Species Die Off

Recent research has stumbled upon an alarming trend: As average temperature increases, many bird populations decline. The survey, conducted by the University of Utah, found that warming of 3.5 degrees Celsius may result in 600-900 extinctions of land bird species.

5. Animals Could Get Bigger…

Researchers in California have found that birds around San Francisco Bay and Point Reyes National Seashore have slowly gotten bigger over the last 27 to 40 years. The finding was particularly interesting because it counters some conventional wisdom about how animals will respond to climate change.

6. …Or They Could Get Smaller

That conventional wisdom suggests that animals—and cold blooded species in particular—will shrink in size as the global average temperature increases. Some research, too, has extended this trend to certain mammals.

Polar Bears Experiencing Skin Lesions and Hair Loss

Nine Alaskan polar bears near the southern Beaufort Sea were found with skin lesions and hair loss in the past two weeks, according to the The United States Geological Survey (USGS). It is not known what is causing these conditions, but they could be man-made and natural biotoxins, radiation, contaminants, auto-immune diseases, nutritional, hormonal and environmental factors. The same problems were also observed in seals and walruses in the region.

According to a USGS memo,”Evidence of alopecia and other skin lesions may be difficult to see unless the bear can be observed closely. In the polar bears that USGS has observed to date,
the most common areas affected include the muzzle and face, eyes, ears and neck.”

In the southern Beaufort Sea region a USGS survey estimated there were about 1,526 polar bears. Because of climate change, there is less and less ice available for polar bears in this area. Offshore oil drilling began there in the early 1970s due to the presence of large oil and gas reservoirs.

Polar bears are vulnerable to man-made pollutants due to the fact wind currents carry them there from other places, so they can accumulate in large quantities. Polar bear bones have already been weakened by these pollutants.
