The fact that there is a natural greenhouse effect (that the atmosphere restricts the passage of infra-red (IR) radiation from the Earth’s surface to space) is easily deducible from; i) the mean temperature of the surface (around 15ºC) and, ii) knowing that the planet is normally close to radiative equilibrium. in IPCC TAR).

The paper results from a major computational effort, based on running a state-of-the-art climate model (the CESM model with horizontal resolution 1° for the ocean/sea ice and 2° for the atmosphere/land component) for 4,400 model years.

These interactions were thought to lead to alternating decades-long intervals of warming and cooling centered in the extra-tropical North Atlantic that play out on 40-60 year timescales (hence the name). Background. any oscillation that was produced has to be internally generated.

Furthermore, if you squinted, you could perhaps convince yourself that there was a correlation to solar activity – well, at least Soon could ( Soon, 2005) ).

I had reason to be reviewing the history of MSU satellite retrievals for atmospheric temperatures recently. Remember ‘satellite cooling’?]. This was before Wentz and Schabel (1998) pointed out that orbital decay in the NOAA satellites was imparting a strong cooling bias (about 0.12 and that had a raw trend of -0.01

Simply put, gases that trap heat in the atmosphere (. Yes, water vapor is the most abundant GHG in the atmosphere, but it is a different animal and water vapor does control Earth’s temperature but, there is never a change in the amount of water on Earth.). We have been doing this GHG work since 2005.

It was a bold claim and some researchers initially struggled to accept the implications because it meant that energy must be flowing from the “cool” 6000 K surface of the Sun into the hotter corona – seemingly in violation of thermodynamics. This estimate was later revised upwards to 10 6 K and above. million kelvin (green).
