Abstract. A workshop on Long-Term Monitoring of Global Climate Forcings and Feedbacks was held February, at NASA's Goddard Institute for Space Studies to discuss the measurements required to interpret long-term global temperature changes, to critique the proposed contributions of a series of small satellites (Climsat), and to identify needed.

We describe the rationale for long-term monitoring of global climate forcings and radiative feedbacks as a contribution to interpretation of long-term Cited by: Climate forcing has to do with the amount of energy we receive from the sun, and the amount of energy we radiate back into space.
Variances in climate forcing are determined by physical influences on the atmosphere such as orbital and axial changes as well as the amount of greenhouse gas in our atmosphere.

An Editorial; C. Miller, F. Bretherton. Long-Term Climate Monitoring by the Global Climate Observing System. CLIMATE. Climate is the average state of the atmosphere and the underlying land or water, on time scales of seasons and longer.
Climate is typically described by the statistics of a set of atmospheric and surface variables, such as temperature, precipitation, wind, humidity, cloudiness, soil moisture, sea surface temperature, and the concentration and thickness of sea ice.
Forests and Climate Change: Forcings, Feedbacks, and the Climate Long-term monitoring of global climate forcings and feedbacks book of Forests Article Literature Review in Science () July.
Long-term monitoring of forcing and other climate variables at much improved accuracy is needed to detect and understand future changes. In addition, surface-based observational networks for the detection of long-term changes in climate variables need to be improved, notably by accounting for local changes (e.g., in land use and vegetation.
Climate feedbacks are processes that change as a result of a change in forcing, and cause additional climate change. An example of this is the "ice-albedo feedback." As the atmosphere warms, sea ice will melt. Ice is highly reflective, while the underlying ocean surface is. Long-term climate response to stabilized and overshoot anthropogenic forcings beyond the twenty-first century Article in Climate Dynamics 28(2) February with 20 Reads.
We summarize here forcing datasets used in GISS global climate models over the years. Note that the forcings are estimates that may be revised as new information or better understandings of the source data become available.
We archive both our current best estimates of the forcings, along with complete sets of forcings used in specific studies. What Makes the Climate Change. The two components of climate change are forcings and feedbacks.
Natural climate forcings, which have operated throughout geological time, include solar evolution and cycles, continental drift, continental collisions and mountain building, volcanism, orbital variations, and ocean current cycles. Global warming - Global warming - Feedback mechanisms and climate sensitivity: There are a number of feedback processes important to Earth’s climate system and, in particular, its response to external radiative forcing.
The most fundamental of these feedback mechanisms involves the loss of longwave radiation to space from the surface. Since this radiative loss increases with. Change of climate forcings, in watts per square meter, between and Vertical bars show estimated uncertainty.
Uncertainty for "other greenhouse gases" is similar to that for carbon dioxide. (Data from Hansen et al., "Efficacy of Climate Forcings." See sources.) Note: This figure is based on Figure 28(b) of the "Efficacy" paper. Also, a lot of discussion has come up recently over Richard Lindzen’s ERBE analysis in which he purports to show that global climate sensitivity is small, and that the net effect of climate feedbacks is to dampen the so-called Planck response.
That. Jing-Jia Luoa,Wataru Sasaki, and Yukio Masumoto, Indian Ocean warming modulates Pacific climate hed online before print Octodoi: /pnas PNAS Octo Radiative forcing is a measure of the change in energy balance as a result of a change in a forcing agent (e.g., greenhouse gaseous, aerosol, cloud, and surface albedo) to affect the global energy balance and contribute to climate change.
It has been used as a measure to investigate the climate sensitivity of an Earth system component in recent Intergovernmental Panel on. Global warming and climate change are terms for the observed century-scale rise in the average temperature of the Earth's climate system and its related effects.
Description Long-term monitoring of global climate forcings and feedbacks PDF
Multiple lines of scientific evidence show that the climate system is warming.   Although the increase of near-surface atmospheric temperature is the measure of global warming often reported in the popular. Global warming is the ongoing rise of the average temperature of the Earth's climate system and has been demonstrated by direct temperature measurements and by measurements of various effects of the warming.
It is a major aspect of climate change which, in addition to rising global surface temperatures, also includes its effects, such as changes in precipitation. Introduction  A climate forcing, measured in W/m 2, is an imposed change of the planetary energy examples of forcing agents are an increase of atmospheric CO 2 or a change of solar irradiance.
It is implicitly assumed in most discussions of global climate change that global forcings of the same magnitude will yield similar changes of global mean by: Stratospheric aerosols that are caused by a major volcanic eruption can serve as a valuable test of global climate models, as well as severely complicate tropospheric-aerosol monitoring from space.
In either case, it is highly desirable to have accurate global information on the optical thickness, size, and composition of volcanic aerosols.

We report sensitivity study results, Cited by: 2. James Edward Hansen (born Ma ) is an American adjunct professor directing the Program on Climate Science, Awareness and Solutions of the Earth Institute at Columbia is best known for his research in climatology, his Congressional testimony on climate change that helped raise broad awareness of global warming, and his advocacy of Fields: Atmospheric physics.
The take home message is that there are a number of human climate forcings, in addition to CO2, that have a long term effect on the climate system.
nitrogen deposition. black carbon (soot) 3. dust from degraded land. land cover/land use change. All of the global-scale state shifts noted above coincided with global-scale forcings that modified the atmosphere, oceans and climate.
These examples suggest that past global-scale state shifts Cited by: HEARTLAND REPORT’S CLAIM: “Doubling the concentration of atmospheric CO 2 from its pre-industrial level, in the absence of other forcings and feedbacks, would likely cause a warming of ~°C to °C, almost 50 percent of which must already have occurred.
VERDICT: This claim only highlights warming in the absence of any feedbacks, meaning it has limited relevance to.

Things that change the balance between incoming and outgoing energy in the climate system are called forcings. Natural forcings include volcanic eruptions.
Manmade forcings include air pollution and greenhouse gases. A climate forcing, such as greenhouse gas increases, may trigger feedbacks like the loss of sunlight-reflecting : Rebecca Lindsey.
Welcome to Climate Change Monitoring. The Climate Change Monitoring Services (CCMS) is taking steps to bring this evidence to the public's attention, with the goal of building support for action to reduce the heat-trapping gas emissions that cause global warming.
Fingerprints of global warming are indicators of the global, long-term warming. Global average surface temperature is only one of many variables included in climate models, and models can be evaluated against many other climate metrics.
There are specific “ fingerprints ” of human warming in the lower atmosphere, for example, that are seen in .More Evidence that Global Warming is a False Alarm: A Model Simulation of the last 40 Years of Deep Ocean Warming June 25th, by Roy W. Spencer, Ph. D. NOTE: I am making available the Excel spreadsheet with the simple forcing-feedback .There are a variety of climate change feedbacks that can either amplify or diminish the initial forcing.
Some parts of the climate system, such as the oceans and ice caps, respond more slowly in reaction to climate forcings, while others respond more quickly. There are also key threshold factors which when exceeded can produce rapid change.
