NOAA: 2013 November Average Global Temperature was the 345th Straight Month of Above Average Global Temperatures and Earth’s Warmest November of Record

November was a hot month for planet Earth. Government scientists reported Tuesday, December 18, that last month was the warmest November on record, across Earth, since record-keeping began in 1880.Connect the Dots on Global Warming

In 2010, the United States emitted over 6.8 billion metric tons of greenhouse gases (CO2e). Greenhouse gases are emitted by all sectors of the economy, including electric power (34% of total), transportation (27%), industry (21%), residential & commercial (11%), and agriculture (7%).

The growing demand for air travel has resulted in increasing levels of greenhouse gas (GHG) emissions from the aviation sector, despite efficiency improvements. Compared to driving, traveling by bus or taking the train, flying has a greater climate impact per passenger mile, even over longer distances. It’s also the mode of freight transport that produces the most emissions.

A special characteristic of aircraft emissions is that most of them are produced at cruising altitudes high in the atmosphere. Scientific studies have shown that these high-altitude emissions have a more harmful climate impact because they trigger a series of chemical reactions and atmospheric effects that have a net warming effect. The IPCC, for example, has estimated that the climate impact of aircraft is two to four times greater than the effect of their carbon dioxide emissions alone.

The National Oceanic and Atmospheric Administration says average global temperature, for water and land surfaces combined, was 56.6 degrees (13.7 Celsius). That’s 1.4 degrees (0.78 degrees Celsius) above the 20th century average. It was the 37th consecutive November with above-average temperatures. The last below-average November was in 1976.

It was also the 345th straight month with above-average temperatures. That’s almost 29 years. Among the November hot spots: much of Eurasia, Central America and the Indian Ocean. In Russia, it was the warmest November on record. But parts of North America were cooler than average.

The Intergovernmental Panel on Climate Change (IPCC) states that “the atmospheric concentrations of carbon dioxide, methane, and nitrous oxide [greenhouse gases] have increased to levels unprecedented in at least the last 800,000 years. Carbon dioxide (CO2) concentrations have increased by 40% since pre-industrial times, primarily from fossil fuel emissions and secondarily from net land use change emissions [deforestation]. The ocean has absorbed about 30% of the emitted anthropogenic carbon dioxide, causing ocean acidification”.

“Global mean sea level will continue to rise during the 21st century.  The rate of sea level rise will very likely exceed that observed during 1971 to 2010 due to increased ocean warming and increased loss of mass from glaciers and ice sheets.”

“It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century”, the IPCC report states, and ” cumulative emissions of CO2 largely determine global mean surface warming by the late 21st century and beyond. Most aspects of climate change will persist for many centuries even if emissions of CO2 are stopped” and that “this represents a substantial multi-century climate change commitment created by past, present and future emissions of CO2.

I am presently a Volunteer for Habitat for Humanity, Madison, Wisconsin. I oppose all long (>500 miles) distance travel (via fossil fuel burning) for nonessential purposes and all ownership of more than one home. I am opposed to militarism in any form particularly for the purpose of monetary gain. I am a Strong believer in people everywhere having the right to speak their minds openly, without any fear of reprisal, regarding any concerns; especially against those in authority who are not acting for the public good?in a timely fashion and in all countries of the world not just the U S.. My identical twin, Pat, died in June 2009. He was fired from his job with the National Weather Service despite having a long and successful career as a flood forecaster with the Kansas City National Weather Service. He took a new position in the Midwest Regional Office in Minneapolis. Unfortunately, Pat’s work for the NWS went sour after he began to see the evidence for concern about rising global temperatures shortly after relocating to Minneapolis, and how they appeared to effect of flooding on the Red River that flows out of Canada before entering the U.S. in North Dakota. . Pat and I conversed on a regular basis with other scientists on the Yahoo Group named “Climate Concern “ and by personal email. The NWS denied his recommendation to give his public presentation o n his research at the “Minneapolis Mall of America” in February 2000, which deeply affected h,im. I will h He strongly believed the information ought be shared with the public to which I concurred. That was the beginning of the vendetta against my brother, Patrick J. Neuman, for speaking strongly of the obligations the federal government was responsible for accurately informing the citizenry. A way great similar response to my raising the issue of too many greenhouse gases being emitted by drivers of vehicles on Wisconsin highway system, my immediate supervisors directed: “that neither global warming, climate change nor the long term impacts upon the natural resources of Wisconsin from expansion of the state highway system were to be any part of my job requirements, and that I must not communicate, nor in a memorandum to all the bureau, shall any person who works in the same bureau I do communicate with me, neither verbally on the phone, by email.
