But the majority is from the following

2) isotastic adjustment.

Thank you for turning this political. I'm sure the 75% of people in the U.S. that believe in Climate Change are wrong and who knows all Commie Leftist...

Na...I come here for the content mostly. I get the political rhetoric when ever I read different news sources online. Although being a 3 boat person is making me a little nervous..

No, the Mi'kmaq were semi-nomadic [seasonally].

In winter, they hunted caribou, moose, and small game, inland.
In summer, they fished and gathered shellfish, and hunted seals, on the coasts.

The single-family inland winter hunting camps were scattered, but during the spring and summer, Mi'kmaq families joined others, to form coastal villages. They would travel between the same areas for a few years, until their knowledge of the land told them that resources were becoming less abundant. At this time they would seek another area, to allow the land they had been using to recover. By spreading out the impact in this way, no one area became seriously depleted.

The issue of coastal flooding has nothing to do with the reservation system. The concept of private property, however, does limit the adaptation strategies, available to the Mi'kmaq [or anyone].

Thanks, for asking. Questions are one way to replace ignorance, with knowledge.
No thanks, for the gratuitous political remarks.
Of course, the invasion & conquest, of the Americas, by European invaders, lies at the root of many [most?] indigenous peoples' current problems.

For at least a million years indigenous populations the world over have been forced to assimilate and interbreed with invaders or die out.

DNA sequencing proves we all have a bit of Neanderthal genes... why is it so?

This is NOTHING new.

WEBB IS FULLY DEPLOYED!

The largest, most complex telescope ever launched into space is fully deployed.

NASA's new space telescope opened its huge, gold-plated, flower-shaped mirror on Saturday [January 9, 2022], the final step in the observatory's dramatic unfurling.

The last portion of the 6.5-metre mirror swung into place at flight controllers' command, completing the unfolding of the James Webb Space Telescope.

More powerful than the Hubble Space Telescope, the $10-billion US Webb will scan the cosmos for light streaming from the first stars and galaxies, formed 13.7 billion years ago.

To accomplish this, NASA had to outfit Webb with the biggest and most sensitive mirror ever launched — its "golden eye," as scientists call it.

The riskiest operation occurred earlier in the week, when the tennis court-size sunshield unfurled, providing subzero shade for the mirror and infrared detectors.

Webb's main mirror is made of beryllium, a lightweight yet sturdy and cold-resistant metal. Each of its 18 segments is coated with an ultra-thin layer of gold, highly reflective of infrared light.

The hexagonal, coffee table-size segments must be adjusted in the days and weeks ahead, so they can focus as one, on stars, galaxies and alien worlds, that might hold atmospheric signs of life.

Webb should reach its destination, 1.6 million kilometres away, in another two weeks; it's already travelled more than one million kilometres from Earth since its Christmas Day launch. If all continues to go well, science observations will begin this summer.

Astronomers hope to peer back to within 100 million years of the universe-forming Big Bang, closer than Hubble has achieved.

Who stopped them from being nomadic ( which would have made the costal flooding which has been happening to them for as long as they have been a people's . A non issue)

Who built the dam that changed how the river deposits sediments and how the sand bars migrate?

So I stand by my statement the Canadian government is the real problem there.

“T cells from common colds cross-protect against infection with SARS-CoV-2"

People with higher levels of T cells, from common cold coronaviruses, are less likely to become infected with SARS-CoV-2.

High levels of T-cells, from common cold coronaviruses, can provide protection against COVID-19, an Imperial College London study [1] has found, which could inform approaches for second-generation vaccines.

The study [1], which began in September 2020, and published on Monday, looked at levels of cross-reactive T-cells, generated by previous common colds, in 52 household contacts of positive COVID-19 cases, shortly after exposure, to see if they went on to develop infection.

It found that the 26 who did not develop infection, had significantly higher levels of those T-cells, than people who did get infected. Imperial did not say how long protection from the T-cells would last.

There are no ‘natural’ disasters

Hazards such as floods, droughts, and heatwaves might be natural, but disasters are human-made, argue [1] disaster researcher Emmanuel Raju, sustainability researcher Emily Boyd, and climate scientist Friederike Otto. Disasters occur when hazards meet vulnerability — such as when the most vulnerable groups of people are pushed to live in hazardous areas. The authors argue that “a discourse in which the role of human activity in disasters is clearly communicated — as opposed to blaming nature, or the climate — will be more conducive to a proactive, equitable, and ultimately successful approach to reducing impacts of disasters”.

What dolphins reveal about the evolution of the clitoris” ~ by Jessica Hamzelou

Patricia Brennan has forged a controversial career, in studying the twist and turns of the evolution of animal genitalia. A biologist based at Mount Holyoke College, in South Hadley, Massachusetts, her latest research [1] suggests that bottlenose dolphins’ (Tursiops truncatus) tissues, nerves, and structures indicate that their clitorises have evolved to function for pleasure, something she says makes sense, given the amount of sex the animals have.

Upper Ocean Temperatures Break Records for Sixth Year

In 2021, according to a new summary [1] of two international datasets, the wave of warmth in our oceans hit a new peak, eclipsing the influence of cooler regional episodes [La Niña].

While last year's ocean warming is unprecedented, it was no exception. This is the sixth year in a row that the world's ocean temperatures have exceeded anything we've measured before.

Since the late 1950s, when reliable recordings of climate change first began, each decade has hosted warmer oceans than the last. Since the 1980s, the authors of the summary [1] say there has been an "unambiguous" increase in marine temperatures.

The heat is being felt right across the board. Last year, the North Pacific Ocean, the North Atlantic Ocean, and the Mediterranean Sea all experienced the hottest marine temperatures on record.

Altogether, the upper 2,000 meters in our oceans absorbed 14 more Zettajoules (ZJ) in 2021 than in 2020.

In 2019, scientists calculated human warming of the ocean was equivalent to dropping the equivalent of five Hiroshima bombs into the ocean per second.

"The oceans are absorbing most of the heating from human carbon emissions," says climate scientist Michael Mann from Pennsylvania State University. [2]
