The New Record Low Arctic Sea Ice and Our Weather

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…

Scientist Reveals 7% More Water Vapor Fuels Storms Today

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…

Expert asks, can we control the climate crisis in time?

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? Stefan Rahmstorf’s homepage http://www.pik-potsdam.de/~stefan

Most accurate climate models predict greatest future warming

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…

Francis: A Trigger for Rapid Arctic Warming

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).

The 936 PPM CO2 NASA Model Prediction

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

CO2 makes largest Jump in recorded history, hits record high

The concentration of carbon dioxide in the atmosphere increased at record speed last year to hit a level not seen for more than three million years, the UN has warned. https://www.theguardian.com/environment/2017/oct/30/global-atmospheric-co2-levels-hit-record-high The Keeling Curve animation via Scripps Oceanography https://www.youtube.com/watch?v=rEbE5fcnFVs

Global Average Temperature vs Temperature Extremes

In his March 2017 talk “The Brutal Logic of Climate Change”, at the University of Sheffield, Aaron Thierry outlined many of the aspects of climate change.This video here is the excerpt on temperature anomalies.
