Did you hear that because the Arctic sea ice is melting, Polar bears are prey switching from seals to reideer?

[Fireguy17]

nope.
Did you hear that around 200 million years ago about half or the US was covered in ice long before man was around?
But I did hear that last year more ice formed in the arctic than in a long long time.

[Ad_Quid_Orator]

200 million years ago there were no ice caps.

[Fireguy17]

there were glaciers all over the place, and now there is more ice in the Antarctica polar cap.
Yes, there were ice caps around 200 million years ago. During the Triassic-Jurassic period, the Earth was dominated by the supercontinent Pangaea, which extended to the South Pole. While there may have been localized ice caps, the overall climate was significantly warmer than today, making extensive ice sheets unlikely.

Probably the inspiration for the abominable snowman... The Rudolph cartoon predicted this long ago.

Sad for deer, but dang, it is not easy to catch a deer. Honestly, I'd switch to humans.

[DishLady]

Maybe they’re just switching to leaner meats for Spring Break…. (Kidding. I hadn’t heard about that. Is there a scientific study about it?)

[Phoenix98]

They do actually vary their diets for a similar reason so your not exactly far off.

[purplepoppy]

Reindeer won't have the calorific blubber that seals have. They're going to have to hunt a lot more Reindeer to meet their needs

[AI Opinion]

I have heard about the changes in polar bear diets due to the melting Arctic sea ice. As their traditional prey, seals, become harder to catch, some polar bears have indeed started to prey on reindeer and other available land animals. This behavior reflects the adaptability of polar bears in response to climate change, but it also highlights the severe impacts of environmental changes on wildlife. 🌍🐻‍❄️

[Phoenix98]

Polar bears varying their diets isn't exactly new information. Normally, in the months when the sea is frozen, they enjoy a diet of offshore seals. But their use of supplementary food sources in the leaner summer months has been known for decades.

Another thing to note is that polar bears will attack and eat anything they come across especially humans. So if they happen to come across prey they will eat it even if it's not part of their normal diet.

Also according to Nasa and and the European space agency the artic ice has been increasing not decreasing.

"Also according to Nasa and and the European space agency the artic ice has been increasing not decreasing."

Can you link a source?

[Phoenix98]

Yeah give me a second I need to go find it.

[Phoenix98]

The Agency one was a outdated article so I won't link that one that was my bad on that one.

But the Nasa one should be within the last 3 years. And I believe this one said the artic or Antarctic ice sea was increasing.

The graphs wouldn't load but the average global average goes through a 3-5 year warming an cooling cycle influenced by the El Nino Southern Oscillation so it wouldn't surprise me if the ice had been expanding for the past 3 years: But over longer periods of time, we can still sea the temperature trend upwards.



For a while, the Antarctic sea ice had been expanding. But this is because so much ice had melt from the continent had flowed into the Southern Ocean. The cold meltwater cancelled out the warming effect and it also decreased the salinity. The less salty water is, the higher the freezing point which is why the Antarctic had been expanding. But around the mid 2010s, the overall impact of the warmer temperatures overwhelmed the affects of the meltwater and the Antarctic sea ice began shrinking.

[Phoenix98]

Either way I'm not really to worried about it.

The earth goes through cycles of global warming and global cooling periods. The reason for this is the global warming periods let warm climate creatures, fauna and biomes expand and grow in number and space in preparation while the cold climate creatures and biomes shrink.

But then when the global cooling cycle begins the cold climate creatures and biomes expand and grow in number while the warm climate creatures, fauna and biomes shrink. But because they had centuries to expand and grow in number the species are able to survive that global cooling cycle. Same goes for the cold climate creatures and biomes during the global warming period.

If we didn't' have these global warming and global cooling periods entire species would get wiped out and go extinct so it's important for the balance of the ecosystem that we have both global warming and global cooling evens.

And this was confirmed by climate scientists decades. There was a documentary on it and everything it's actually pretty interesting and would definitely recommend looking into it if that sort of stuff interests you.

[Ad_Quid_Orator]

Warm periods generally have greater biodiversity than cooler ones BUT rapid change (warming and cooling) has been linked to many mass extinctions. Among these are the End Permian Extinction, the worst of them all which saw the extinction of 90% of all species on Earth.

[Phoenix98]

These aren't rapid there's usually a build up and they last for quite a long time.

But I do agree with you on that yes rapid climate changes are bad.

[exitseven]

The sharks are eating the seals so the polar bears have to change their menu.

[Kelley1]

I have read those lies. However, the truth is that the Polar ice is increasing.

[FunkyMonkee]

No, mostly because I don't believe in the climate hoax.

[Dargil]

Nope. Polar bear numbers are increasing.

[douride2]

Sounds like another fairy tail to me.
