«No one has
yet shown that CH4 [methane] from hydrates is
reaching the
atmosphere today,» Thornton says.
Isn't the main problem that, even if we stopped adding any fossil - fuel - derived CO2 to the
atmosphere, the ocean circulations haven't
yet reached «steady state» — i.e., a stable thermocline and deep ocean temperature — and therefore THAT is the source of the Hansen et al. «heat in the pipeline»?
Most of the Methane is NOT
Reaching the
Atmosphere,
YET.
Brienen et al. estimate that an increase of 3.8 GtC in necromass (dead wood) produced since 1983 has
yet to
reach the
atmosphere.
Yet carbon dioxide would continue to build up in the
atmosphere — breaching the level of 450 parts per million by volume (ppmv) that most climatologists now recommend as an upper limit, then passing the 550 ppmv mark that is the goal of many current policy initiatives, and eventually
reaching 1,000 ppmv, a level not seen on Earth since the days of the dinosaurs.
Most deserts in the world
reach 100 % relative humidity daily when morning dew forms
yet they are still have exceedingly dry
atmospheres with large temperature differences between daily high and nightly low.
Many believe that increased water vapor, solar variations in radiation and magnetic flux, our relative position in the solar system, the tilt of our planet's axis, the clearing of our
atmosphere of pollutants which allows more sunlight to
reach the ground, or our position in the Milky Way galaxy that affects the amount of radiation
reaching our
atmosphere and affecting cloud formation, are also important and are not (and can not be
yet) adequately considered in the computer models used by the IPCC consensus.
Maybe some sort of crushed comet could hit the upper
atmosphere with a sort of spread - out shotgun blast of tiny particles, all vaporizing long before they
reach the earth,
yet creating a «disturbance in the force.»
Isn't the main problem that, even if we stopped adding any fossil - fuel - derived CO2 to the
atmosphere, the ocean circulations haven't
yet reached «steady state» — i.e., a stable thermocline and deep ocean temperature — and therefore THAT is the source of the Hansen et al. «heat in the pipeline»?
The paleo record is not at all ambiguous: as temperature rose in response to natural increases in insolation more GHGs were released into the
atmosphere (mainly CO2, CH4, and H2O), and then those GHGs induced
yet more warming, which released
yet more GHGs, etc., until equilibrium — and a warmer climate — was
reached.
Today we're just skipping that first natural warming step by injecting GHGs directly into the
atmosphere, which is already inducing warming, which will result in
yet more GHGs being released naturally, etc., until equilibrium — and a warmer climate — is
reached.
