Climate data from air, land, sea and ice in 2013 reflect trends of a warming planet

Increases in temperature, sea level and CO2 observed; Southern Hemisphere warmth and Super Typhoon Haiyan among year’s most notable events

July 17, 2014

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.

“These findings reinforce what scientists for decades have observed: that our planet is becoming a warmer place,” said NOAA Administrator Kathryn Sullivan, Ph.D. “This report provides the foundational information we need to develop tools and services for communities, business, and nations to prepare for, and build resilience to, the impacts of climate change.”

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 parts per million (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 Nino Southern Oscillation (ENSO)-neutral conditions in the eastern central Pacific Ocean and a negative Pacific decadal oscillation pattern in the North Pacific had the largest impacts on the global sea surface temperature during the year. 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 plus or minus 0.4 millimeters (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.

State of the Climate in 2013 is the 24th edition in a peer-reviewed series published annually as a special supplement to the Bulletin of the American Meteorological Society. The journal makes the full report openly available online.

Bryce, isn't it true that before the ice age at the time of dinosaurs the planet was much warmer, green house gases much higher levels than today to feed the much bigger and more abundant plant life. To make it sound that humans can change the climate and stop something that is occurring naturally as it has in the past is irresponsible. We need to prepare and use tools to adapt. We will use farming as an example, it is forecasted the the upper Midwest ( prairie pothole region) will experience more rain and larger events yet at the same time these groups are forcing policy that are taking away drainage rights and tools away from this region. These are the facts. Current policies are not addressing the problems correctly.

Bryce: I am not sure where you are getting your data, but red-faced NOAA had to admit recently that there has been no warming since 1996. The U.N. data is completely fabricated.

I'm wondering why nitrous oxide doesn't get more press? Its mentioned here but there are no quantitative values. Nitrous oxide is 296 times more persistent than CO2 - my generation won't make a climate difference with that! In my area, environmentalists are constantly attacking drainage tile. Unwittingly, they don't seem to realize how much drainage tile can reduce denitrification - the production of nitrous oxide. Are the environmentalists ignorant about agriculture or is global warming/carbon dioxide their avenue to assert socialist behavior?!

Farming forty miles south of Chicago, we had our third coldest winter in 140 years and we just set another record for the lowest high temperature for the July 15th of 67 degrees for the high that day. Curt is right about the tile.

I guess that since Chicago's weather determines the price of grain it should also determine the state of global climate? I did see in C-3 website (climate, conservative, consumer) what Tom refers to in his reference. This website shows with graphs that increases in atmospheric carbon (which by the way it denies is happening on the same page) corresponds to increase of grain yields since 1960 so it concludes that carbon is a good thing to grain production, let's tell seed companies like Pioneer that we haven't needed their research, yields are going up because of increases in carbon that C-3 also says is a hoax! This is the "science" that conservatives point to in climate denial. You know I was in the super market and saw a newspaper that claimed Elvis never died and that a "Batboy" was found in a cave! Its all in print, I am sure its real and so why the heck listen to 97% of climate scientists or any scientists when we just want to believe what we want to believe?

Jay, it's good to make jokes. but just to be clear we are talking about proposed laws that will hurt our ability to feed the world. You can't eat dirt, you can't eat recyclables, Pioneer, Monsanto and other seed companies are giving us the traits we need to double our yields so we can feed and fuel this world. I am positive the earth is warming and cooling and warming and cooling. I wonder if the reported rise in greenhouse gasses was caused by plants using less co2 in 2012? Plants shut down before grain fill in a lot of fields.

The climate has always been changing. What caused the glaciers in North America to melt? It must have been GLOBAL WARMING!!!
Posted by JEFF HANSON at 8:01AM CDT 07/21/14
I'm referring to the glacial meltdown that took place hundreds of years ago! Was that caused by native americans keeping warm around their campfires?
Posted by JEFF HANSON at 8:37AM CDT 07/21/14
Oh you're so silly Jeff, natives and as far as that the entire worlds population wasn't burning 90 million barrels of oil per day plus millions of tons of coal,,, in fact they weren't burning ANY fossil fuels! What you fail to understand is that fossil fuels are stored carbon which accumulated over millions of years (yes there are scientists out there that believe the world is older then 5000 years) and releasing this carbon in huge quantities for only <100 years is turning us back to a prehistoric atmosphere. And yes Mark you are right, you can't eat dirt so what kind of ag will exist when all the fossil fuels are depleted? There are better ways to power our transportation system and power the grid, why don't we make the switch now instead of drilling deeper and mining Canadian tar sands which takes a HUGE carbon footprint to extract??? Hanity and Rush are right, there is a "Mideast" of oil in North America,,, only they fail to say it will take another "mideast" of oil to extract it!
Posted by Jay Mcginnis at 9:50AM CDT 07/21/14
Jay,you still haven't answered as to why North America warmed up to melt the glaciers hundreds of years ago?
Posted by JEFF HANSON at 12:01PM CDT 07/21/14
I'm waiting to here for your response Jay. It seems people don't look any farther than they can see. The glaciers melting and moving thru the glacial lake system seems to never be addressed along with the ice from the last ice age melting.
Posted by Unknown at 7:34PM CDT 07/21/14
Oh wow,,, you guys are on to something I am sure scientists never thought of this! Hurry and call NOAA so they can tell 97% of all scientists they are wrong!
Posted by Jay Mcginnis at 5:28AM CDT 07/22/14
Well then answer the question Jay, your here shooting off your mouth as to how much fossil fuels is to blame for our current climate change. You surely should have an educated idea as to why the glaciers melted. And keep NOAA and your scientist out of it.
Posted by GWL 61 at 6:27AM CDT 07/22/14
Don't feel bad guys, I've been asking that glacier melting question to all my "green" friends for years to no avail. I'm sure all the fossil fuel use does not do the climate any good, I'm all on board with that. Surely one of those 97 percent of scientists can answer this question and shut all of us simpletons up.
Posted by TOM DRAPER at 7:30PM CDT 07/22/14
Again how times change. Going to school in the 70"s we were told by scientist that the world was returning to the ice age because the sun was burning itself out. Al Gore starts a global warming fad and all the "experts" jump in for the ride. Why is the almighty USDA not in on this, all we need to clear the air is one of their corrupt "reports" or "estimates" to guide everyone in the right direction like their markets they control.

I have posted these statistics before, but here they are again regarding the subject of "global cooling" predictions 40 years ago--A survey of the scientific literature has found that between 1965 and 1979, 44 scientific papers predicted warming, 20 were neutral and just 7 predicted cooling. So while predictions of cooling got more media attention, the majority of scientists were predicting warming even then. Out of 71 papers reviewed, only TEN percent predicted cooling in the future. 44 out of 71--or SIXTY-TWO percent--predicted warming.

I'd like to see some statistics posted pertaining to the fraudulent figures that NOAA has been throwing around. Haven't seen too many responses by the usual suspects when someone posts about THAT 900 lbs. gorilla in the corner of the room.
Posted by Brandon Butler at 8:25AM CDT 07/23/14
Mr. Butler--are you referring to the temperature trends that NOAA has been cataloguing and reporting on? That topic was brought up four years ago in the so-called "Climategate" controversy, and a review of the research and data scientists were working with found no manipulation of the numbers. And regarding the solar cycle--yes, the solar cycle is less at this time, which would have brought on an overall cooler trend in temperatures, but has not. We continue to see global temperatures increase as highlighted in the climate reports.
