How Are Penguins Affected By Climate Change in the NORTHERN Hemisphere?
What are some facts or statistics showing that penguins are being affected by climate change in the northern hemisphere NOT southern.
and also what are they being affected by and how do these factors change the penguins life in a negative way ( being related to climate change or global warming) Thanks!
Hmmm let me think, how are a non existent group of animals affected by something that doesn’t exist.– thats a tough one
Wild Penguins do not exist in the Northern Hemisphere.

The closest thing was the great awk. It went extinct nearly 16 decades ago. http://en.wikipedia.org/wiki/Great_Auk
Edit:
Most of the Global warming that has happened in the last 3 decades has happened in the Arctic (0.5 kelvins), while the Antarctic has not changed much at all. http://www.ssmi.com/msu/msu_data_description.html#figures
During the 3 decades from 1940 to 1970, when the earth was cooling, most of the cooling happened in the Arctic (-0.5 kelvins), while the Antarctic did not change much at all. http://en.wikipedia.org/wiki/File:Global_Cooling_Map.png
So perhaps, you were asking because most of the changes have been in the Arctic. Note that the cooling map linked to above looks like a negative of the warming map linked to above.
Edit @Antarcticice:
The increase of 0.5 Kelvins for the Arctic, and the lack of change in the Antarctic is based on the TLT (Temperature Lower Troposphere) map in the SSMI.com (satellite measurements) link that covers the last 31 years. The decrease of the same amounts between 1940 and 1970 is based on the Wikipedia link right next to the numbers.
Yes, Arctic warming and cooling at twice the global average is about right as per the same links.
If you wish to know whether or not the ice cover in the Arctic is "normal", you need to consider the 95% confidence level, normally considered the minimum for statistical significance. (Expect a result outside of 95% confidence once in twenty samples if everything remains normal.) This is at 2.1 standard deviations from the curve for a 22 sample data set. Here is a link to your graph with the the 94% confidence level (2 standard deviations) added. http://nsidc.org/data/seaice_index/images/daily_images/N_stddev_timeseries.png
Notice that the current ice cover is not an outlier. http://en.wikipedia.org/wiki/Outlier
As for where the penguins actually live, ice cover is also normal, but slightly above average. http://nsidc.org/data/seaice_index/images/daily_images/S_stddev_timeseries.png
Interesting article you provided about the Antarctic warming. They used 1957 as a base reference point based on the establishment of one of the weather stations there in that year. Note that they did not say how much it warmed, and that they used the same data for the last 31 years that was used to create the map that shows almost no net change for the last 31 years. Their data includes the period from 1957 to 1979 based on a hand full of temperature recording stations that the TLT map I linked to does not. The cooling map that shows no net cooling in Antarctica from ~1940 to ~1970 is based on averages around the start/stop dates based on existing temperature recordings from existing stations there.
You can show either a warming trend or a cooling trend for Antarctica if you cherry pick your dates.
The closest Penguins to the Northern Hemisphere are the Galapagos Penguin, the Galapagos Islands are right on the equator but these penguins are able to survive here because of the Humboldt current. A cold water current, which flows up the west coast of S. America.

"Most of the Global warming that has happened in the last 3 decades has happened in the Arctic (0.5 kelvins), while the Antarctic has not changed much at all."
Not sure what NW Jack is basing this on, as Arctic temperature is rising at around twice the global average.

As far as the Antarctic not warming

Yeah, right.
And for those deniers still pretending Arctic sea ice has returned to normal

It’s terrible. It appears to have wiped them out completely. Exactly the same has happened to the Polar Bears in the SOUTHERN hemisphere.
It is interesting that polar bears only live in the NORTHERN Hemisphere (The Arctic)
And penguins only live in the SOUTHERN Hemisphere (The Antarctic, and the southern parts of Australia and NZ, Africa, and South America and the Galapagos)
Also interesting is the fact that the only thing protecting the penguins of Antarctica is the freezing temperatures that keep most humans and their exterminating ways away…
Well that would mean that the cooling units at zoos would have to be doing more work to cool ambient air to keep their habitats nice and cold for them. This means increased operating costs for the zoos.That’s about all you can say since wild penguins don’t live in the northern hemisphere.
penguins are native to Antarctica (Southern Hemisphere), not the Arctic (Northern Hemisphere.)
