Real World: Monitoring Earth's Energy Budget with CERES

In this NASA eClips video segment learn how NASA uses CERES, a satellite in our Earth observing system, to make accurate measurements of energy leaving the Earth. Discover how NASA studies the interactions of clouds with sunlight and heat to determine how much heat is emitted back into space. Demonstrations are used to help support the segment.

Look up Richard Lindzen´s paper on the earth´s energy budget and you will find that CERES actually reports the opposite, (science is numbers, nothing more) of what Lin Chambers says in this video.

Because the cost of adaptation is 5-20% of the cost of amelioration, it is financially correct to get "worked up" if the confidence is as low as 20%.

The confidence is about 90%.

And satellite energy imbalance measurements can be confirmed with ocean heat content measurements.

[WombatsOnUTube]

1 W/m2 will cause warming, and that warming will continue while there is an energy imbalance.

Global warming is only 0.02°C per year.

The numbers are about right.

NASA will tend to use the satellites that are up there rather than the better ones that are purely hypothetical. They turn in less hypothetical measurements. And small samples rapidly build up a statistically accurate picture.

All of the rise in CO2 is from man. More than all - fossil fuels plus cement has released about twice the CO2 required to cause the observed increase in atmospheric concentration. This is because both the oceans and terrestrial biosphere have been carbon sinks.

Surface temperature is important because that is the metric for global warming. Satellite data has little history, and even over that time no consistency of instrumentation. And interpretation is non trivial.

Not all of the raise in CO2 is from man, but a good part of it is.

Land based temperatures are actually not all that great, they only tell you the surface temperature. Sattelite data is still good, but bad at looking int the energy balance your talking about.

You need to watch the whole world at the same time to really get a reading on that.

The weather system is still far from being understood and it plays a greater roll the the greenhouse effect in saying what the temperature will be.

[WombatsOnUTube]

270ppm natural. 390ppm current. 44.4% increase.

Trace gas does not imply not a major part of the greenhouse effect.

The 45% increase in CO2 is from combustion of fossil fuels.

Satellite data only goes back 30 years, and the technology has changed over that time. It is non trivial and arguable to interpret and calculate a temperature at surface.

Land based temperature measurements are better.

NASA _are_ scientists.

[Silentsam7532]

greenhouse gasses are 45% higher? Thats changing the numbers. CO2 is higher and thats only a trace gas, not a major part of the greenhouse effect.

The amount of CO2 man produces is very small. For every 100000 molecules of air we add 1 CO2 molecule every 5 years. This isnt going to cause a drastic change.

I am taking this from a climatologist. Changes in CO2 are measured in parts per million.

Satellite data shows nothing alarming. You need to read what the scientists say, not the journalists.

[WombatsOnUTube]

The science does not agree with you that there is nothing abnormal in the climate.

Greenhouse gases are 45% higher than normal. Greenhouse effect will follow.

Meteorologists also believe that it is due to mam.

The American Meteorological Society, The Australian Meteorological and Oceanographic Society, The Canadian Meteorological and Oceanographic Society, The Royal Meteorological Society and The World Meteorological Organization have all released statements supporting the science behind AGW.

[WombatsOnUTube]

Of the 928 scholarly papers with the ISI keywords "global climate change" in the decade to 2003, not one took the position that the current warming is mostly natural.

Scientists agree.

People who don't believe in global warming don't follow the science.

[Silentsam7532]

These are small trends over extremely short periods of time. In the long run there is nothing abnormal with the current climate.

We are still coming out of cool period in the earths history. Ofcourse there is warming, and thats all the scientists agree on, is that its gotten warmer. They dont agree that man causes it.

model builders tend to belive its due to man, meteorologists tend not to.
