Arctic sea ice decline has long been projected to occur. 2018 and 2017 are the two lowest winter time Arctic sea ice records observed. Disappearing sea ice and moisture transport into the Arctic are believed to cause something called Arctic amplification, which in turn has been linked to two effects (weaker westerly winds, and intensified…
“Rapid Arctic Climate Change: What’s cloud got to do with it?” presented by Patrick Taylor. Originally presented at the Fall AGU 2017 conference on Monday, December 12, 2017 at 10:00 a.m.
Jennifer Francis, Ph.D., Research Professor I, Department of Marine and Coastal Sciences, Rutgers University, speaks about extreme weather changes. And how are those related to climate change? In this presentation, Dr. Francis will explain new research that links increasing extreme weather events with the rapidly warming and melting Arctic during recent decades. Evidence suggests that…
The vital ozone layer has continued to deplete in recent years over the densely populated mid-latitudes and tropics, while it is recovering at the poles https://www.ethz.ch/en/news-and-events/eth-news/news/2018/02/decline-stratospheric-ozone.html Evidence for a continuous decline in lower stratospheric ozone offsetting ozone layer recovery https://www.atmos-chem-phys.net/18/1379/2018/ Ozone loss may have caused mass extinction https://climatenewsnetwork.net/ozone-loss-may-have-caused-mass-extinction Ozone Pollution Maps Show Spikes Amid Broad…
There are 32 million gallons worth of mercury, or the equivalent of 50 Olympic swimming pools, trapped in the permafrost. For context, that’s “twice as much mercury as the rest of all soils, the atmosphere, and oceans combined. And it could be released. https://www.washingtonpost.com/news/energy-environment/wp/2018/02/05/the-arctic-is-full-of-toxic-mercury-and-climate-change-is-going-to-release-it Ambarchik: Research on permafrost at the Siberian arctic coast https://www.youtube.com/watch?v=ZhGcJnRgzy4 Permafrost…
Jim White from the University of Colorado, on climate change, January 2018. Human activities are summarized in this recent lecture.
CO2 emissions from fossil fuel burning caused the Arctic to warm at least twice as fast as the rest of globe, resulting in the disappearance of Arctic sea ice – which in turn weakens the polar vortex, which in turn favors cold air intrusion into lower latitudes, and vise-versa.
Stefan Rahmstorf speaks at the 2017 Bonn climate conference, explaining the basics of global climate change, and outlines our current emissions pathway – asking if we can control the climate crisis. The talk is titled Climate Action and Human Wellbeing at a Crossroads: Historical Transformation or Backlash?

The Arctic is warming faster than anywhere else on Earth, affecting people in the region, fish and wildlife they depend on for food, and their environment. This unprecedented change has ramifications far beyond the region for the global economy, weather, climate, sea level, trade and security. Watch the full Arctic Report 2017 AGU press conference…
The climate change simulations that best capture current planetary conditions are also the ones that predict the most dire levels of human-driven warming, according to a statistical study released in the journal Nature Wednesday. https://www.washingtonpost.com/news/energy-environment/wp/2017/12/06/the-most-accurate-climate-change-models-predict-the-most-alarming-consequences-study-claims Greater future global warming inferred from Earth’s recent energy budget https://www.nature.com/articles/nature24672 Greater future global warming inferred from Earth’s recent energy…
In this lecture by Alex Thomas, he explains how does carbon dioxide interact with water and why the ocean can store so much carbon. What is the effect on the ocean’s pH and how does this in turn determine how much carbon the ocean can store.
Jennifer Francis from Rutgers University speaks about our atmosphere with a scope on the Arctic response to climate change and the connection to weather. This video is part of a panel presentation published by Earth Institute November 2017, with already improved sound quality (reduced humming sound).

Another “warm” and slow freeze season in the #Arctic. Sea ice extent is the 2nd lowest on record for the date (2016 – lowest) & 1.9 million km^2 below the 1980s average… https://twitter.com/ZLabe/status/932663163476045825

This NASA visualization is based on the latest IPCC report, and uses the business as usual scenario, where carbon dioxide concentrations rise to 936 parts per million—more than double today’s levels of 400 parts per million—by the year 2100. Temperature anomalies are estimated to be close to 4°C in the Arctic. https://svs.gsfc.nasa.gov/cgi-bin/details.cgi?aid=11453
The ozone layer protects life on Earth from ultraviolet radiation but it is also a powerful greenhouse gas. Satellites can provide measurements of atmospheric ozone and monitor distribution changes with the seasons.
