WMO: 2011-2015 is the warmest five year period on record
Posted by Greg Laden on November 25, 2015 
The World Meteorological Organization has announced that they expect 2015 to be the warmest year on record, and that we are in the warmest five year period on record. We are speaking here of global surface temperatures, though similar descriptions probably apply to the upper 2000 meters or so of the ocean as well. The…
Honey, We Broke The Global Warming Graph. Again.
Posted by Greg Laden on October 22, 2015 
We’re gonna need a bigger boat. Well, actually we’re gonna need a bigger y-Axis. This has been happening for a while. NOAA has just published September’s global surface temperature, which turns out to be 0.90C above their baseline (20th century average). According to NOAA, this is the highest value for September on record, 0.19C higher…
Arctic Sea Ice in 2015
Posted by Greg Laden on October 5, 2015 
Every year the sea ice that covers the northern part of the Earth expands and contracts though the winter and the summer. The minimum extent of the sea ice is usually reached some time in September, after which it starts to reform. Human caused greenhouse gas pollution has increased the surface temperatures of the earth,…

The recently produced Massive Open Online Course on climate science denial is chock full of great videos that should be at everyone’s fingertips. HERE is a list of the videos. Use it well and powerfully.
Will 2015 be warmer than 2014?
Posted by Greg Laden on April 26, 2015 
That is a good question, and difficult to answer. If it turns out to be, it will be the warmest calendar year in the instrumental record, which goes back into the 19th century. Regardless of what El Nino (ENSO) does, 2015 will be a warm year. Why? Because everything is warm and getting warmer and…
Global warming’s effects are coming on faster than previously thought.
Posted by Greg Laden on January 22, 2015 
Arctic sea ice decline happened faster than expected. This has the effect of accelerating global warming because less of the Sun’s energy is reflected back into space by ice. Northern Hemisphere snow also sends some of that energy back into space. The amount of snow cover we have is also declining. The warming of the…
New York Times Puts AGW Above The Fold, But …
Posted by Greg Laden on January 17, 2015 
The New York Times put the news of 2014 being the warmest year on their front page, in the precious space known as “Above The Fold.” But, the venerable paper of record continues to give credence to science denialists by calling them “skeptics,” and continues to imply that there really is a debate between consensus…
Top Global Warming Skeptic Explains Global Warming
Posted by Greg Laden on January 10, 2015 
This is serious. A highly regarded and widely recognized planetery physicist put together the most dangerous scientific ingredients that exist: skepticism of the established science, a comprehensive list of hypotheses that stood in opposition to that established science, a huge amount of data, a healthy amount of funding including a good chunk from energy companies…
Global Temperature A Century Ago Vs. Today
Posted by Greg Laden on December 22, 2014 
With what may be the warmest year in centuries about to close, I thought it would be fun to have a graphic comparing the march of global average temperature over several years about a century ago with the present state of affairs. This graphic is based on NASA’s data, using John Abraham’s estimate for the…
How scientists unraveled the El Niño mystery
Posted by Greg Laden on December 4, 2014 
The Road to Paris is a web site created by the ICSU, “…a non-governmental organization representing a global membership that includes both national scientific bodies (121 National Members representing 141 countries) and International Scientific Unions (30 Members),” founded in 1931. If the ICSU had not existed when the UN was formed, the UN would have…
