What the Hockey Stick missed about climate change [Video]

The infamous hockey stick figure was published in 1999. A new paper just blew it out of the water with an INCREDIBLE reconstruction. Learn how climate change altered human history on CuriosityStream! https://www.curiositystream.com/simonclarkYou may have already heard of the 1999 hockey stick created by Michael Mann, Malcolm Hughes, and Raymond Bradley. It’s a frequent skeptic talking point, and was involved in a whole scandal called climategate that rocked the scientific world. Eventually however it was validated by dozens of independent studies, and its conclusions accepted – the world is currently undergoing warming the likes of which humans have never seen before. Last month however, the hockey stick got an amazing upgrade. A new paper by Osman et al reconstructed the past 24,000 years of climate using new techniques, and gave us new insights into just how unprecedented anthropogenic global warming really is.You can support the channel by becoming a patron at http://www.patreon.com/simonoxfphysNOTES/REFERENCES(1) https://agupubs.onlinelibrary.wiley.com/doi/abs/10.1029/1999GL900070(2) This is a simplification – tree rings can sometimes act as a proxy for temperature or for precipitation, depending on the typical climate at a location(3) https://geni.us/mannhockeystick(4) https://www.nature.com/articles/s41586-021-03984-4(5) I’m slightly oversimplifying here, what the paper did was attribute mechanisms to the principal components (PCs) of the temperature timeseries. PCs allow a signal to be broken down into components, ranked by size, that, when combined, reconstruct the signal. Solar and orbital forcing appears to be responsible for PC2, which was itself responsible for 3.5% of the total signal. The vast majority (over 90%) of the warming was accounted for by PC1, which could be explained almost entirely by greenhouse gases and changes in albedo.(bonus) Ars Technica did a nice article writing this up, if you’d like some more material! https://arstechnica.com/science/2021/11/scientists-extend-and-straighten-iconic-climate-hockey-stick/Check out my website! https://www.simonoxfphys.com/———- II ———-My twitter – http://www.twitter.com/simonoxfphysMy facebook – http://www.facebook.com/youtubesimonMy insta – http://www.instagram.com/simonoxfphysMy goodreads – http://www.goodreads.com/simonoxfphys———- II ———-Music by Epidemic Sound: http://epidemicsound.comThis video is about the hockey stick graph created by Michael Mann and his collaborators in the MHB99 paper reconstructing the earth’s past climate. I talk about how Mann missed key information in his analysis due to limitations of data at the time, and how instead of an eigenvector approach, a new study using Bayesian reconstruction paints a different picture of the Earth’s past. The planet has never been as warm as it currently is during the holocene, with the medieval warm period and the little ice age barely featuring in the timeseries of past climate. This new nature paper from Osman et al is really something, amazing new climate change science that highlights present global warming.Huge thanks to my supporters on Patreon: Andrew Knop, Shab Kumar, Cameron Grey, Brady Johnston, Liat Khitman, Jesper Norsted, Kent & Krista Halloran, Rapssack, abruptbanana, Kevin O’Connor, Timo Kerremans, Thines Ganeshamoorthy, Jerry Moore, Sam Harvey (the ever lasting student), Ashley Wilkins, Michael Parmenter, Samuel Baumgartner, Dan Sherman, ST0RMW1NG 1, Adrian Sand, Morten Engsvang, Josh Schiager, Farsight101, K.L, poundedjam, Daan Sneep, Felix Freiberger, Chris Field, Robert Connell, Jaime Stark, Kolbrandr, , Sebastain Graf, Dan Nelson, Shane O’Brien, Alex, Fujia Li, Harry Eakins, Will Tolley, Cody VanZandt, Jesper Koed, Jonathan Craske, Albrecht Striffler, Igor Francetic, Jack Troup, SexyCaveman , James Munro, Oskar Hellström, Sean Richards, Kedar , Alastair Fortune, bitreign33 , Mat Allen, Anne Smith, Rafaela Corrêa Pereira, Colin J.

January Jones- Chef Curtis Stone’s Cooking Philosophy& Mother Nature 12/12 by Ms January Jones [Video]

My Cooking Philosophy My cooking philosophy is to keep it simple and cook with naturally produced ingredients just as Mother Nature intended. My philosophy really evolved while coming up the ranks in Marco’s restaurants. We worked only with the best local and seasonal ingredients and treated them simply. Filming Surfing the Menu cemented my philosophy even further as it enabled me to personally meet farmers and manufacturers, and visit orchards, vineyards, paddocks, fish farms, even an apiary, and much more, to truly see where food originally comes from. When Mother Nature worked out what we should be eating at different times of the year, she did a pretty good job, so listen to her. Food that is in season just tastes better and you really don’t have to do a whole lot to it to make it taste great! It is always less expensive, and chances are it hasn’t been artificially treated or travelled halfway across the world to reach your kitchen.

FLYING OVER SCOTLAND (4K UHD) Beautiful Nature Scenery with Relaxing Music | 4K VIDEO ULTRA HDScotland (Scots Gaelic: Alba) is the second-largest of the constituent nations of the United Kingdom. It has a sixty mile (96km) land border with England to the south, and is separated from Northern Ireland by the North Channel of the Irish Sea. The capital is Edinburgh and the largest city is Glasgow.Scotland is surrounded by the bracing waters of the North Sea to the east, and the North Atlantic Ocean to the west and north. There are over 700 islands, mostly in groups to the west (the Inner Hebrides and Outer Hebrides) and north (Orkney Islands and Shetland Islands).Scotland is a beautiful country well known for its dramatic scenery of mountains and valleys, rolling hills, green fields and forests, and rugged coastline. While everyone knows the Highlands for this, Scotland is beautiful in the Lowlands, islands and the flat lands of the North-East as well.scotland, scotland 4k, scotland relaxation film, 4k, scotland relaxation, relaxation film, calming music, stress relief, scenic relaxation, 4k video, 4k video 60fps, video 4k, 4k, 4k videos, relax 4k, piano, ultra hd, piano music, bgm, background music, focus, soothing relaxation, calm, soothing, music, beautiful piano music, Piano Relax, piano relaxing, relaxing music, nature sounds, scotland, australia relaxation film, scotland relaxation, relaxation film, calming music, stress relief, scotland 4k video, scotland island, scotland 4k, scotland untra hd, scotland travel, 4k nature, 4k 60fps hdr, Relaxation films, relax music, relaxing music, spa music, Beautiful Nature, Meditation Music, Yoga music, 4k, Italy, Venice, Sad piano, Cello, Strtings, Dolomites, vecchio bridge, Rome, tuscany, Praiano, Ravello, Montepulciano, Calabria, Positano amalfi, roccella jonica, verona, Amalfi, Violin, scotland, scotland 4k, nature, nature 4k, 4k, 4k video, piano music, music for meditation, music for sleeping, relax music, soothing, healing music, relaxation music, stunning nature, relax, sleep music, dream music, stress relief, background music, calm, drone film, aerial film, blue planet, simple happiness, nature video, instrumental music, relaxing music, planet earth, scotland 4k drone, scotland drone, Calming Music, drone footage, scotland nature, scotland travel, scotland vlog📌 Helios Records:◾ Spotify: https://spoti.fi/2OgiA6M◽ SoundCloud: https://bit.ly/1V3lGKg◾ Youtube: https://bit.ly/2BQ5Y3D◽ Instagram: https://bit.ly/2Zjztnc◾ Facebook: https://bit.ly/2ZhUKgV📌 Contacts:◽ relax@wondermusic.us◾ channel@wondermusic.us
