Why you're a freakin genius!!! I never thought of that! We'll just add more CO2 to the atmosphere which will create more heat...which will create them bigger leaves...which will give off more oxygen...

As can be seen in the first picture, the traditional Passage, shown in yellow, entering between Devon and Baffin Islands in the east and exiting between Banks and Prince Patrick Islands in the west, is still probably impassable without assistance of an icebreaker. However, if one looks closely at a blown up version of the second picture it becomes clear that the traditional passage might be possible or soon become possible for a brave person without an icebreaker. The southern passage outlined in red will likely remain open for another month at least.

If one isn't experienced viewing these satellite images, it may not be clear that the view of the western end of the passage is obscured by fairly heavy clouds.

The psuedo-skeptic led effort to bastardize and co-opt Professor Zarkova's findings has already been discussed in detail here. All the times that Zarkova appears in the video, she's taken out of context. The instance at 2:46 is especially obvious.

Apparently you missed this video, which might help anyone interested in ferreting out the truth make sense of some of the things one sees in the media.

Of course, if one were merely interested in seeking confirmation for their biases, they could continue to seek out inaccurate, poorly produced and misleading videos expressing vague opinions of internet bloggers, rather than synopses of the science, done by the scientists who did the work and performed the studies.

Some examples of which I speak follow.

Can't imagine why anyone would deliberately seek out ignorance though...

There are thousands like these available, any reasonably informed person has no excuse to doubt the constantly improving science of and evidence for rapid, human-induced climate warming we are currently experiencing.


Or, if you prefer to read your science, here's a good one, from 1978 no less. (So much for the pseudo-skeptic assertion that in the 70's everyone was predicting 'global cooling'.)

There are also thousands of these available, all it takes is the same effort to find real science by the real scientists, instead of the half-baked warm and fuzzies of bloggers opinions.

Guess you're still using a magnetized needle floating on oil for navigation?

In case you're unsure of what the Northwest Passage is, can I append this simplified map, courtesy of Google?



Obviously, on the map from Enviroment Canada and the satellite picture from NASA below, the southern northwest passage is open now, and has been for at least 2-3 weeks.

A further note on the current state of arctic ice. A cursory look at any of the images at this website,

https://lance.modaps.eosdis.nasa.gov...6222.terra.4km

which covers the entire arctic, will reveal that the traditional view of the 'ice pack' has undergone a paradigm shift in the last 15 years. The days of an seemingly endless expanse of frozen wasteland are gone, for who knows how long, replaced by a rapidly shifting mass of thin floes and increasingly open water. The only reason this year probably won't make the top 3 lowest extent records is because of the lack of wind sufficient to compact the ice. I'll leave it to your imagination, and the scientists work, to figure out the cause of that one...

Life expectancy & population almost certainly would not have increased as shown without such large amounts of (non sustainable) free energy dug up from the ground.

So yes, a connection is very likely.

To those who have taken me to task for playing up the right/left correlation with views on climate change... you're right, it's not so clear-cut.

Two former Republican EPA administrators throw support to Clinton

In their statement, Ruckelshaus and Reilly say that Republicans have a long history of environmental stewardship, noting that Nixon created the EPA, and argue that Trump, a real estate mogul, “threatens to destroy that legacy.”

The former administrators take particular exception to Trump’s stand on climate change, which he has characterized as a hoax. They say climate change is “the singular health and environmental threat to the world today” and praise the Paris agreement adopted in December by nearly 200 nations.

“To back away now, as Trump wants to do, would set the world back decades — years we could never recover,” the statement from Ruckelshaus and Reilly says. “The young people in this country deserve far better than that as our legacy.”

Since coral bleaching is caused, in part, by excessively warm water temperatures, and since it will undoubtedly take many decades of concerted effort by the whole world community to reverse that temperature rise, folks are working on different schemes to help coral before they are totally wiped out. Hence the Australian Government buying and closing a major source of pollution of a section of the Great Barrier Reef, which may give the reef a fighting change to survive.

Rejection of experts spreads from Brexit to climate change with 'Clexit' | The Guardian

Clexit calls for withdrawal from climate treaties, rejects the conclusions of 97% of climate science experts and 95% of economics experts.

Brexit support and climate denial have many similarities. Many Brexit Leave campaign leaders also deny the dangers of human-caused climate change. Older generations were more likely to vote for the UK to leave the EU and are more likely to oppose taking action on climate change; younger generations disagree, and will be forced to live with the consequences of those decisions. On both issues there’s also a dangerous strain of anti-intellectualism, in which campaigners mock experts and dismiss their evidence and conclusions...

Global warming could 'unfreeze' waste buried in old Greenland military base | USA Today

Global warming is slowly thawing out a once top-secret subterranean U.S. nuclear base in northern Greenland, potentially exposing the environment to radioactive coolant, PCBs, and raw sewage that the military originally believed would stay entombed for millennia.

The hazardous waste could emerge by the end of the century, according to a new, peer-reviewed study published Thursday in Geophysical Research Letters, a journal of the American Geophysical Union. The melting seems likely to bring modern-day environmental and political headache...

It was the Queensland state government that purchased Springvale. Good on them, I reckon. However to put the 500,000 tonnes quoted into perspective, one major river that faces the reef and whose catchment lies outside the wet tropics deposits 10 times that value of sediment into the ocean annually.

One can conclude from these two posts that the health and well being of zooxanthellae is far more important than the health and well-being of homo sapiens.

Umm, it's toxic radioactive waste dropped in a hole in the ground. Ain't nuttin' gonna make it any more dangerous than it already is.

UK-funded ice breaker in 'elite' Arctic tourism row | BBC

Funded by the UK government, the RRS Ernest Shackleton normally carries out support work for the British Antarctic Survey (BAS). But this summer the ice breaker has been chartered to accompany a luxury liner's voyage in the Arctic. Critics say it is inappropriate for a vessel dedicated to science to support tourism in such a fragile area...

Climate change could force huge migrations for people and animals living near the equator | Washington Post

...The problem presented in the study is that temperatures throughout the tropics — which stretch from about 23 degrees north of the equator to 23 degrees south — tend to be fairly uniform. It’s only once you move into the subtropics that temperatures begin to cool significantly as you travel north or south toward the poles. And as climate change causes temperatures to rise, the tropics also warm more or less to the same extent throughout.

Even a little bit of warming at the equator can be devastating to the organisms living there, Hsiang pointed out, simply because it’s so hot already. “Once it’s 95 degrees, one more degree can actually be very damaging to crops, very damaging to human health,” he said...

That's true. I worked in Baltimore as a federal agent for six years and when it got hot, there were even more killings than in the winter time (which was not easy to do).
