Climate data from air, land, sea and ice in 2013 reflect trends of a warming planet - comments updated 7/18/2014

This might explain why Fiscal Times had an article yesterday trying to cast doubt on global warming. The article has already been removed. I have noticed that conservative web sites often/usually post articles trying to cast doubt on news they don't like very shortly before, like the day before, I see it on the internet. They know that once people have a belief, it is very hard to change it, even with massive amounts of proof that the belief is not true. I have no doubt that they monitor scientific news in order to try to preempt information they don't like.

Update :

How interesting. Two days ago, Fiscal Times had a global warming denialist column. I posted comments, with links, about the facts. I get e-mails when people post replies to my comments, and yesterday, when I went to respond to the expected ignorant replies, I got the "Page not found" message. So today I got several more e-mails of replies, with today's date for the date of their posting. Is Fiscal Times able to block me from loading their page, maybe based on the IP address of my computer? The link is http://www.thefiscaltimes.com/Columns/2014/07/17/How-Media-Bias-Censors-Debate-Climate-Change
I know e-mails can be delayed when going from place to place. But the message contains a date and time for the reply, which indicates that the replies were posted today.

More and more interesting. When I did an advanced Google search, I was able to find and load the page. The date part of the address is 2014/07/16, not 2014/07/17 as was given in the e-mail reply option. So the link is
http://www.thefiscaltimes.com/Columns/2014/07/16/How-Media-Bias-Censors-Debate-Climate-Change

Of course, many of the replies are full of more misinformation.

And now I am not able to put a comment at all on the Fiscal Times article.

In 2013, the vast majority of worldwide climate indicators—greenhouse gases, sea levels, global temperatures, etc.—continued to reflect trends of a warmer planet, according to the indicators assessed in the State of the Climate in 2013 report, released online today by the American Meteorological Society.

Scientists from NOAA’s National Climatic Data Center in Asheville, N.C., served as the lead editors of the report, which was compiled by 425 scientists from 57 countries around the world (highlights, visuals, full report). It provides a detailed update on global climate indicators, notable weather events, and other data collected by environmental monitoring stations and instruments on air, land, sea, and ice.

The report uses dozens of climate indicators to track patterns, changes, and trends of the global climate system, including greenhouse gases; temperatures throughout the atmosphere, ocean, and land; cloud cover; sea level; ocean salinity; sea ice extent; and snow cover. These indicators often reflect many thousands of measurements from multiple independent datasets. The report also details cases of unusual and extreme regional events, such as Super Typhoon Haiyan, which devastated portions of Southeast Asia in November 2013.

Highlights:

Greenhouse gases continued to climb: Major greenhouse gas concentrations, including carbon dioxide (CO2), methane and nitrous oxide, continued to rise during 2013, once again reaching historic high values. Atmospheric CO2 concentrations increased by 2.8 ppm in 2013, reaching a global average of 395.3 ppm for the year. At the Mauna Loa Observatory in Hawaii, the daily concentration of CO2 exceeded 400 ppm on May 9 for the first time since measurements began at the site in 1958. This milestone follows observational sites in the Arctic that observed this CO2 threshold of 400 ppm in spring 2012.

Warm temperature trends continued near the Earth’s surface: Four major independent datasets show 2013 was among the warmest years on record, ranking between second and sixth depending upon the dataset used. In the Southern Hemisphere, Australia observed its warmest year on record, while Argentina had its second warmest and New Zealand its third warmest.

Sea surface temperatures increased: Four independent datasets indicate that the globally averaged sea surface temperature for 2013 was among the 10 warmest on record. El NiƱo Southern Oscillation (ENSO)-neutral conditions in the eastern central Pacific Ocean and a negative Pacific decadal oscillation pattern in the North Pacific. The North Pacific was record warm for 2013.

Sea level continued to rise: Global mean sea level continued to rise during 2013, on pace with a trend of 3.2 ± 0.4 mm per year over the past two decades.

The Arctic continued to warm; sea ice extent remained low: The Arctic observed its seventh warmest year since records began in the early 20th century. Record high temperatures were measured at 20-meter depth at permafrost stations in Alaska. Arctic sea ice extent was the sixth lowest since satellite observations began in 1979. All seven lowest sea ice extents on record have occurred in the past seven years.

Antarctic sea ice extent reached record high for second year in a row; South Pole station set record high temperature: The Antarctic maximum sea ice extent reached a record high of 7.56 million square miles on October 1. This is 0.7 percent higher than the previous record high extent of 7.51 million square miles that occurred in 2012 and 8.6 percent higher than the record low maximum sea ice extent of 6.96 million square miles that occurred in 1986. Near the end of the year, the South Pole had its highest annual temperature since records began in 1957.

Tropical cyclones near average overall / Historic Super Typhoon: The number of tropical cyclones during 2013 was slightly above average, with a total of 94 storms, in comparison to the 1981-2010 average of 89. The North Atlantic Basin had its quietest season since 1994. However, in the Western North Pacific Basin, Super Typhoon Haiyan – the deadliest cyclone of 2013 – had the highest wind speed ever assigned to a tropical cyclone, with one-minute sustained winds estimated to be 196 miles per hour.
