https://phys.org/news/2019-01-landscape-unseen-years.html Glacial retreat in the Canadian Arctic has uncovered landscapes that haven't been ice-free in more than 40,000 years and the region may be experiencing its warmest century in 115,000 years, new University of Colorado Boulder research finds. The study, published today in the journal Nature Communications, uses radiocarbon dating to determine the ages of plants collected at the edges of 30 ice caps on Baffin Island, west of Greenland. The island has experienced significant summertime warming in recent decades. "The Arctic is currently warming two to three times faster than the rest of the globe, so naturally, glaciers and ice caps are going to react faster," said Simon Pendleton, lead author and a doctoral researcher in CU Boulder's Institute of Arctic and Alpine Research (INSTAAR).

However, the degree to which recent Arctic warming is unprecedented remains debated. Ages of entombed plants in growth position preserved by now receding ice caps in Arctic Canada help to address this issue by placing recent conditions in a multi-millennial context. Here we show that pre-Holocene radiocarbon dates on plants collected at the margins of 30 ice caps in Arctic Canada suggest those locations were continuously ice covered for > 40 kyr, but are now ice-free. We use in situ 14C inventories in rocks from nine locations to explore the possibility of brief exposure during the warm early Holocene. Modeling the evolution of in situ 14C confirms that Holocene exposure is unlikely at all but one of the sites. Viewed in the context of temperature records from Greenland ice cores, our results suggest that summer warmth of the past century exceeds now any century in ~115,000 years. <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> https://phys.org/news/2019-01-faster-co2.html Faster CO2 rise expected in 2019 January 25, 2019, University of Exeter Figure 1: Forecast CO₂ concentrations at Mauna Loa over 2019 (orange), along with previous forecast concentrations for 2016 (blue), 2017 (green), 2018 (pink) and Scripps Institute measurements (black).

It struck me since my last post that there's a bigger issue here. How in the name of all that's holy is "breaking free of the Pacific Plate" from "the Asian mainland " anything but plate tectonics? There's possibly an argument about where the boundaries are, but plates moving away from each other + carrying landmasses with them is exactly the "myth" that the OP objects to. And that's before we remind him of his "rather fragile" idea about the Earth getting bigger. Essentially, his equestion"Plate Tectonics: A Modern Myth?" is best answered by reference to his own use of shifting plates on the Earth's surface. If it's a myth Doug, - it's one you believe in

Growing up in Australia - where a "shutdown" has only happened once in 1975. It resulted in a "double dissolution" election - where both houses of government are dissolved and a full election is held for every parliamentary seat. I wonder how often the US government would block appropriations if it meant that every senator and congressman would have to face an immediate re-election.

Until he shows some mechanism for the expansion he is just spinning his wheels...

time will tell

Presumably the same unknown mechanism that cause the Earth to blow up like a balloon. And that same magic hides the hollow centre.

Thanks - will Google those

I know what they are. I also see that it is not stated in that link that it applies, You assumed that it did, and the other link indicated your assumption was correct. I am continuously amazed at how people that have impeccable logic in science threads do not seem to have the same in political ones.

Education is always good if you're looking for smart solutions. Access to affordable healthcare is also good. If we took MUCH better care of our environment we could have a lot more people without stressing natural resources or endangering other species. If we did all three of these things, I think our population wouldn't get to become a problem until we had perfected offworld colonization technology. That seems like the most rational course for mankind, to me. But we really should learn to respect ourselves and our home more.

I, for one, don't believe money brings happiness. But that's just me. A poor guy whos mantra doesn't matter.

How are they different? What is unclear about saying the tax applies to assets above $50 million? I am continually amazed at people who presumably pay taxes in countries that use marginal tax rates, and yet do not appear to understand the concept (there are some, including politicians and pundits, who I think only pretend to not understand, in order to advance their agenda)

I didn't remove the tag and now when I smell it it has a weird chemical smell. Is it safe? what is it?
