President, but you're wrong. I think that the people who are alarmist are in a very strong position.
Basic Intermediate While there are many drivers of climate, CO2 is the most dominant radiative forcing and is increasing faster than any other forcing. CO2 is not the only driver of climate CO2 is not the only driver of climate.
There are many influences of climate that all need to be considered together to gain the full picture.
Positive radiative forcing has a warming effect so obviously, negative radiative forcing has a cooling effect. Surface Albedo has changed due to activity such as deforestation.
Consequently, more sunlight is reflected directly back into space, giving a cooling effect of Ozone affects the climate in two ways. The depletion of stratospheric ozone is estimated to have had a cooling effect of Solar variations affect climate in various ways.
There is an indirect effect from UV light which modifies the stratosphere. Note that the radiative forcing from solar variations may be amplified by a possible link between galactic cosmic rays and clouds.
However, considering the sun has shown a slight cooling trend over the last 30 years, an amplified forcing from solar variations would mean a greater cooling effect on global temperatures during the modern warming trend over the last 35 years.
Volcanoes send sulfate aerosols into the stratosphere.
These reflect sunlight, cooling the earth. A strong volcanic eruption can have a radiative forcing effect of up to -3 Wm However, the effect of volcanic activity is transitory - over several years, the aerosols wash out of the atmosphere and any long term forcing is removed.
Aerosols have two effects on climate. The trend in cloud cover is one of increasing albedo which means a cooling effect of Nitrous Oxide reached a concentration of ppb in Methane is actually a more potent greenhouse gas than CO2.
Pre-industrial methane levels, determined from ice core measurements, were around parts per billion ppb.
Currently methane rates are at ppb eg - 1. CO2 levels have increased from around parts per million ppm in pre-industrial times to ppm in CO2 forcing is also increasing at a rate greater than any decade since Anthropogenic RFs and the natural direct solar RF are shown.
by Garth Paltridge An essay on the state of climate change science. (1) Is the science of climate change ‘settled’? The scientific uncertainties associated with climate prediction are the basis of most of the arguments about the significance of climate change(25), and as well are the basis of much of the polarized public opinion on. In particular, a few computers at NASA's Goddard Institute seem to be having a disproportionate effect on global warming. Anthony Watt takes a cut at an analysis I have tried myself several times, comparing raw USHCN temperature data to the final adjusted values delivered from that data by the NASA computers. Dr. Tapio Schneider discusses the science behind human-induced climate change. He is a climate scientist and Professor of Environmental Science and Engineering at the California Institute of Technology. Atmospheric carbon dioxide concentrations are .
Probability distribution functions PDFs from combining anthropogenic radiative forcings. Three cases are shown: Surface albedo, contrails and stratospheric water vapour RFs are included in the total curve but not in the others.How to Write a Thesis Statement.
