Thousands of land and ocean temperature measurements are recorded each day around the globe. Time series of seasonal (red dots) and annual average (black line) of global upper ocean heat content for the 0-700m layer since 1955.
While ocean heat content varies significantly from place to place and from year-to-year (as a result of changing ocean currents and natural variability), there is a strong trend during the period of reliable measurements. Average of monthly snow cover extent anomalies over Northern Hemisphere lands (including Greenland) since Nov 1966. One way climate changes can be assessed is by measuring the frequency of events considered "extreme" (among the most rare of temperature, precipitation and storm intensity values). A large body of evidence supports the conclusion that human activity is the primary driver of recent warming.
Simulated global temperature in experiments that include human influences (pink line), and model experiments that included only natural factors (blue line).
Global climate models clearly show the effect of human-induced changes on global temperatures.
Carbon dioxide concentration (parts per million) for the last 800,000 years, measured from trapped bubbles of air in an Antarctic ice core.
Over the last 800,000 years, natural factors have caused the atmospheric carbon dioxide (CO2) concentration to vary within a range of about 170 to 300 parts per million (ppm).
Global surface temperature (top, blue) and the Sun's energy received at the top of Earth's atmosphere (red, bottom).
The amount of solar energy received at the top of our atmosphere has followed its natural 11-year cycle of small ups and downs, but with no net increase. Eric spends most of his time writing, reading, and hanging out with his chinchilla and bunny. Carbon,which your beloved Biology expert should really explain the genesis of a car-bon first and foremost. Co2 does not cause global warming or a greenhouse effect,nor does it have a needed role in our plant or forest system.
Its NOT my fault that the institute that trains men like Dr.Clint does not have enough information to be accredited in earth Sciences. Planet science does not work the way the Universities and institutes have been trained to think.And like the Reich-stag fire,someone can really rally the troops to further their agenda. If I was a presenter at the forum listed in this promo, everyone with 2 neurons still left to rub together would be on a much different track with a better process to go forth with their support being to assist our eco system and their families. Galaxy historical,periodic processes create the energetic enhancement of our planet here,and over-warm the magma,and stasis will be returned when the componentry that creates this process recdes from our galaxy here.
Like the returning Halleys comet,other systemic energetic events come and go, after this one we have been experiencing for about 40 years recedes,we will actually get cooler. Now that and a multitude of other system information is never spoken to unless one of our science officers tramsmits it. There are certain factions who make a great amount of money and process from no one understanding what what actually transpires,and its criminal but whats even more criminal is for Doc-tuhs to parrot someones information without doing the work it takes to support that information.
I know its tough these days because of the hidden hand up their back,but when someone gives them the science and the logic so they might repair themselves,they usually do not.
The direct warming influence of all long-lived greenhouse gases in the atmosphere today attributable to human activities. Carbon dioxide remains the undisputed king of recent climate change, but other greenhouse gases measurably contribute to the problem. Discussions with colleagues around the time of the 2009 United Nations’ climate conference in Copenhagen inspired three NOAA scientists – Stephen Montzka, Ed Dlugokencky and James Butler of NOAA’s Earth System Research Laboratory in Boulder, Colo.


Scientists know that stabilizing the warming effect of CO2 in the atmosphere would require a decrease of about 80 percent in human-caused CO2 emissions — in part because some of the carbon dioxide emitted today will remain in the atmosphere for thousands of years. The new review paper describes the major human activities responsible for these emissions, and notes that steep cuts (such as 80 percent) would be difficult. The climate-related benefits of reductions in non-CO2 greenhouse gases have limits, Montzka and his colleagues showed.
The scientists also noted in the paper the complicated connections between climate and greenhouse gases, some of which are not yet fully understood.
NOAA’s mission is to understand and predict changes in the Earth's environment, from the depths of the ocean to the surface of the sun, and to conserve and manage our coastal and marine resources. This page presents the latest information from several independent measures of observed climate change that illustrate an overwhelmingly compelling story of a planet that is undergoing global warming.
This includes measurements from climate reference stations, weather stations, ships, buoys and autonomous gliders in the oceans. Red bars indicate temperatures above and blue bars indicate temperatures below the 1901-2000 average temperature.
The global surface temperature is based on air temperature data over land and sea-surface temperatures observed from ships, buoys and satellites. Increasing heat content in the ocean is also consistent with sea level rise, which is occurring mostly as a result of thermal expansion of the ocean water as it warms.
The Climate Extremes Index (CEI) value for the contiguous United States is an objective way to determine whether extreme events are on the rise. The blue band shows how global temperatures would have changed due to natural forces only (without human influence). The 2008 observed value is from the Mauna Loa Observatory in Hawaii and projections are based upon future emission scenarios.
The concentration of CO2 in the atmosphere has increased by roughly 35 percent since the start of the industrial revolution.
By day he can be found working at Quirk Books, promoting awesome books, and by night, he can be found writing them. Clint really should get a much better set of facts before any symposiums to destroy the information of folks who deserve a proper science tasking. The combined influence of the non-CO2 greenhouse gases is equivalent to the heat from about 5 trillion bulbs.
A new study, conducted by NOAA scientists and published online today in Nature, shows that cutting emissions of those other gases could slow changes in climate that are expected in the future. In contrast, cutting all long-lived non-CO2 greenhouse gas emissions by 80 percent could diminish their climate warming effect substantially within a couple of decades. Without substantial changes to human behavior, emissions of the non-CO2 greenhouse gases are expected to continue to increase.
Even if all human-related, non-CO2 greenhouse gas emissions could be eliminated today, it would not be enough to stabilize the warming influence from all greenhouse gases over the next 40 years – unless CO2 emissions were also cut significantly. The non-CO2 gases studied have natural sources as well as human emissions, and climate change could amplify or dampen some of those natural processes, Dlugokencky said. It is worth noting that increasing global temperature is only one element of observed global climate change. There is a clear long-term global warming trend, while each individual year does not always show a temperature increase relative to the previous year, and some years show greater changes than others. The inset shows global mean sea level rise since 1993 - a period over which sea level rise has accelerated. Much of the sea level rise to date is a result of increasing heat of the ocean causing it to expand.


Glaciers have been retreating worldwide for at least the last century; the rate of retreat has increased in the past decade.
The figure to the left shows the the number of extreme climate events (those which place among the most unusual of the historical record) has been rising over the last four decades. The first line of evidence is our basic physical understanding of how greenhouse gases trap heat, how the climate system responds to increases in greenhouse gases, and how other human and natural factors influence climate. Globally, over the past several decades, about 80 percent of human-induced CO2 emissions came from the burning of fossil fuels, while about 20 percent resulted from deforestation and associated agricultural practices. This indicates that it is extremely unlikely that solar influence has been a significant driver of global temperature change over several decades. The category “other”includes a few very long-lived chemicals that can exert a climate influence for millennia.
Therefore cutting emissions would quickly reduce their direct radiative forcing — a measure of warming influence.
Increasingly warm and dry conditions in the Arctic, for example, could thaw permafrost and increase the frequency of wildfires, both of which would send more methane and carbon dioxide into the atmosphere. These measurements are processed, examined for random and systematic errors, and then finally combined to produce a time series of global average temperature change. These year-to-year fluctuations in temperature are due to natural processes, such as the effects of El Ninos, La Ninas, and the eruption of large volcanoes.
Only a few glaciers are actually advancing (in locations that were well below freezing, and where increased precipitation has outpaced melting). The second line of evidence is from indirect estimates of climate changes over the last 1,000 to 2,000 years.
In the absence of strong control measures, emissions projected for this century would result in the CO2 concentration increasing to a level that is roughly 2 to 3 times the highest level occurring over the glacial-interglacial era that spans the last 800,000 or more years.
Phil… before you go criticizing good educators who are trying to make a difference maybe you should look at yourself in the mirror. A number of agencies around the world have produced datasets of global-scale changes in surface temperature using different techniques to process the data and remove measurement errors that could lead to false interpretations of temperature trends.
Notably, the 20 warmest years have all occurred since 1981, and the 10 warmest have all occurred in the past 12 years. The progressive disappearance of glaciers has implications not only for a rising global sea level, but also for water supplies in certain regions of Asia and South America.
These estimates are often obtained from living things and their remains (like tree rings and corals) which provide a natural archive of climate variations.
The close match between the black line and the pink band indicates that observed warming over the last half-century cannot be explained by natural factors alone, and is instead caused primarily by human factors.
The warming trend that is apparent in all of the independent methods of calculating global temperature change is also confirmed by other independent observations, such as the melting of mountain glaciers on every continent, reductions in the extent of snow cover, earlier blooming of plants in spring, a shorter ice season on lakes and rivers, ocean heat content, reduced arctic sea ice, and rising sea levels. These indicators show that the recent temperature rise is clearly unusual in at least the last 1,000 years. The third line of evidence is based on comparisons of actual climate with computer models of how we expect climate to behave under certain human influences. For example, when climate models are run with historical increases in greenhouse gases, they show gradual warming of the Earth and ocean surface, increases in ocean heat content, a rise in global sea level, and general retreat of sea ice and snow cover.
