Today, the only land that is visible from the central part of the Bering land bridge are the Diomede Islands, the Pribilof Islands of St. Paul and St. George, St. Lawrence Island, and King Island.[1]
During the Pleistocene epoch, global cooling led periodically to the expansion of glaciers and lowering of sea levels. This created land connections in various regions around the globe.[19] Today, the average water depth of the Bering Strait is 40–50 m (130–160 ft), therefore the land bridge opened when the sea level dropped more than 50 m (160 ft) below the current level.[20][21] A reconstruction of the sea-level history of the region indicated that a seaway existed from c. 135,000 – c. 70,000 BP, a land bridge from c. 70,000 – c. 60,000 BP, intermittent connection from c. 60,000 – c. 30,000 BP, a land bridge from c. 30,000 – c. 11,000 BP, followed by a Holocene sea-level rise that reopened the strait.[22][23] Post-glacial rebound has continued to raise some sections of coast.
During the last glacial period, enough of the earth's water became frozen in the great ice sheets covering North America and Europe to cause a drop in sea levels. For thousands of years the sea floors of many interglacial shallow seas were exposed, including those of the Bering Strait, the Chukchi Sea to the north, and the Bering Sea to the south. Other land bridges around the world have emerged and disappeared in the same way. Around 14,000 years ago, mainland Australia was linked to both New Guinea and Tasmania, the British Isles became an extension of continental Europe via the dry beds of the English Channel and North Sea, and the dry bed of the South China Sea linked Sumatra, Java, and Borneo to Indochina.

40YEARSWAITING: Expert on climate science in arctic regions despite living in Virginia while paying someone else to tend to his garden impacted by climate.
The posted article is about taking away EPA existing regulations that were put into place to insure that the environment is protected.
Climate change is a different topic. If climate change was the topic then a massive amount of data would need to be researched in order to find accuracy.
Not some one sided dubious publications.
So many studies have been published it can be confusing.
However, when you line them up the majority show a direct correlation to mans influence on climate change not weather.
Common sense again not so common here.
Just look around the world at what is taking place on a daily basis from mans pollution.
How can anyone think that there can be zero impact?
Look at any major city smog. Fires in the Amazon and Australia.
Natural events happen. A volcano erupts. That ends. Not a daily constant bombardment.
The ice caps. Glaciers. The evidence is clear.
But again the article is about our backyard. What we can do to immediately impact things we can control. Our water. Our environment. The air we breath.
I can not understand how anyone would not want to protect that. When we can. And we were.
trumps move is for one reason only not our environment. Fossil fuel companies and lobbyists power to corrupt political policy to insure higher profit.
By allowing industry to pollute it does create jobs. Someone has to clean up pipeline spills and streams choked out by coal plant waste. Just think of the innovations that’ll come about for scrubbing toxins from our air. New filtering techniques to remove fracking waste from tap water. In a few short years with less regulations there’ll be a bigger need for oncologists and respiratory therapists too. I mean all the jobs that’ll be created will be wonderful.
(If you need purple to see the sarcasm you might be a trump voter.)
So, clearly, the solution to Global Warming is to go back to putting fine dusts into the air to trigger an ice age.
See? China and their smog and dust storms has it right. I miss the days where Los Angeles had daily smog reports and smog levels got regular play in the Late Show monologues.
Browns is the Browns
... there goes Joe Thomas, the best there ever was in this game.
Honestly what is so disturbing is how anyone would buy into how this could be good for all?
Forget republican or democrat not relevant.
How can someone not see through what this about?
Companies don't spend millions to lobbyists to corrupt politicians for the good of all. Their motives could not be clearer.
Understanding here is not difficult.
Why not buy bottled water with lead in it?
Playing Devil's Advocate for a moment:
There is reasonable oversight, then there is strangulation and death by bureaucratic micromanagement. If I had to take a flyer of a guess, just as all things in the universe eternally march into entropy, I would say that our government unfailingly sprints towards bureaucratic micromanagement at every turn.
The idea is to find the balance between reasonable oversight while not miring everything in a review process that does nothing but move papers across government desks.

Forget fine dust, we got coal dust by the buckets!
If regulations are removed it clears the path for the companies to reap higher profits.
At the expense of not knowing the impact of their plans.
Even with regulations that have been in place for decades look at the number of disasters that have happened.
This is related to the Pebble Mine. The EPA has been given the ability to reset the table on what has already been voted on by the people of Alaska. This will allow Pebble Mine to move forward when the science provided by numerous sources proved the impact of mine tailings on salmon spawning grounds.
and anytime somebody says they are for freedom of choice, YET they don't want the baby or the father to have the same choice then they are discriminating against the baby and the father.
The father? Lol. The father made a choice to get laid without protection. Maybe he forced the encounter. GMAFB. The father...lol. It’s the women’s right to choose now. Get over it. It’s the law.
It's the law today. It may not be the law next year
Good until then please stop condemning lawful acts, and start condemning unlawful acts. You know like abuse of power and contamination of the air we breath and the water we drink, thank you.
"The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants." Thomas Jefferson.
President Donald Trump, who has referred to climate change as a "Chinese hoax" and a "make-believe scandal" in the past, sounded a much more realistic note recently. Asked whether he still believed his past "hoax" comments, Trump responded: "No, no. Not at all. Nothing's a hoax. Nothing's a hoax about that. It's a very serious subject."
Good until then please stop condemning lawful acts, and start condemning unlawful acts. You know like abuse of power and contamination of the air we breath and the water we drink, thank you.
How about I continue to be me, and you continue to be you.

Ok I’ll stand for prosecuting those who break the environmental laws and against those who abuse their power on the world stage. While you go be yourself and vote for and stand by those same criminals.

That's the thing they don't wish to talk about. I understand some being against regulations. Some are too intrusive. But turning the clock back to when contaminating our air and water to dangerous levels is something that's unforgivable.
Intoducing for The Cleveland Browns, Quarterback Deshawn "The Predator" Watson. He will also be the one to choose your next head coach.
People are affected. Abortion is a difficult topic. And people have strong beliefs regarding it.
But this different. We all are impacted by what happens to the environment around us. Major cities all over the US have contaminated tap water.
Water is a basic life element. We can not live without water. You can live longer without food than you can without water.
Air quality. Back in the day "Smoke Means Jobs". Was a slogan.
What can be more important than our air and water?
Of all the many criminal acts trump has been involved in his policies on the environment are the most destructive and unconscionable.
He has made a conscious assault on everything that been passed to protect the environment.
I don't care about economic numbers. That is a moving target that goes up and down and is influenced by many factors not just the presidency.
But environmental policies like this and others impact our lives and the world around us.
I can not think of anything that has more impact on future generations. Who are we if we can not protect our children and their children with the basic elements of life?
But our parents made the environment cleaner. So did we.
When I was but a child, the Great Lakes were filthy.
Birds had crossed-bill syndrome from pollution.
Never saw an Eagle, rarely saw a hawk. Their eggs were too thin due to DDT.
Couldn't see Los Angeles on a sunny day.
Government was detonating Nukes in the western deserts as the wind blew the fallout east over the pastures, making milk poisonous.
Episodes of high levels of sulfurous smog killed or sickened thousands in Donora, Penn., in 1948, as well as in London in 1952.
These events were the result of very high emissions of sulfur dioxide, smoke, and other particles during stagnant, foggy weather conditions.
As we controlled more traditional pollution sources and urban vehicle fleets grew, a different type of air pollution also arose. Photochemical air pollution—a new phenomenon, distinct from sulfurous smog—clouded the skies over Los Angeles, first recognized in the 1950s. This type of air pollution results from photochemical reactions involving nitrogen oxides and volatile organic compounds (VOCs; ethylene and benzene) that produce ozone and particulate matter. Both cause lung problems, among other deleterious effects, and particulate matter reduces visibility.
Then we made things even cleaner by vastly reducing photochemical air pollution and switching to Natural Gas.
The success of these efforts has caused the most severe air pollution episodes to be distant memories. However, as industrialization spread, air quality concerns also spread to other areas of the globe. For example, recent news headlines warn of extreme air pollution episodes in many Chinese cities, including Beijing, Shanghai, and Guangzhou, showing that urban air pollution remains a major world health issue.
Cleaning up the world’s air is a daunting task. However, a broad review of about 6 decades of efforts in Los Angeles, including how scientists overcame societal and technical challenges, demonstrates that air quality in megacities can and has in fact, be greatly improved.
So you make your additions to a cleaner planet and stop panicking that the world will end without a major overhaul.
Step by Step by Step, each generations makes improvements as we continue to thrive on planet Earth.

Step by step the idiot in the Oval Office steps us back to the times of smog and cross bills. Your generation is now looking to walk us back... for your own profit. Stuff it boomer.
You're so worldly we should bow to your expertise.
I was merely commenting on tastey’s misinformed summation of the city I live in. If I said something like “Archbold is filled with poorly educated backwater folk”, having never been there, I’d be in the wrong. (I wouldn’t say such a thing... as I’ve never been there.) You’d likely respond that the person making such a statement was uninformed in such a thought as they have never been there.
