The simulations also suggest that the removal of excess carbon dioxide from
the atmosphere by natural processes on land and in the ocean will become less efficient as the planet warms.
The long time scale for this recovery arises because ozone depleting gases such as chlorofluorocarbons are only removed from
the atmosphere by natural processes at very slow rates.
And, of course, it would be strange if CO2, CH4, etc. exhibited different behavior if put into
the atmosphere by natural process versus being put into the atmosphere by human emission.
The cost for carbon sequestration with wood burial is low because CO2 is removed from
the atmosphere by the natural process of photosynthesis at little cost.

There, lightning and other
natural processes may also help create fine particulates, but most of these particles would be trapped
by raindrops and harmlessly removed from the
atmosphere, she said.
Albedo modification would work
by lacing the
atmosphere with tiny particles or aerosols that would reflect sunlight and mimic
natural processes.
Carbon dioxide is produced
by many
natural and industrial
processes, which currently result in CO2 levels of 380 ppmv in the
atmosphere.

Natural variability is primarily controlled by exchange of heat between the ocean and the atmosphere, but it is an extremely complex process and if we want to develop better near - term predictive skills — which is looking not at what's going to happen in the next three months but what's going to happen between the next year and 10 years or 20 years or so — if we want to expand our understanding there, we have to understand natural variability better than we do

If used as an average for the globe, it would represent the sum of all CO2 added to, and removed from, the
atmosphere during the year
by human activities and
by natural processes.
My understanding was that about 60 % of the additional carbon we pump into the
atmosphere each year is immediately sequestered
by natural processes, presumably largely biological.
One should also pay attention to other greenhouse gases, particularly methane (from rice paddies, ruminant animal digestive
processes, industrial
processes, and distributed
natural sources, some of which could be triggered to large releases
by warming) and nitrous oxide (from the nitrogen cycle linking the
atmosphere, plants, and bacteria, now exacerbated
by extremely heavy use of nitrogenous fertilizers in agriculture; note, as does Vaclav Smil from the University of Manitoba, that fertilizer use is required to feed half the world's current population.
The Realclimate theory thus fails and the temperature gradient from the body of the ocean to the top millimetre and then the
atmosphere is maintained at or near to the
natural level with the extra warmth being ejected from the system
by the enhanced evaporation / condensation and weather
processes.
Generally, the carbon cycle is balanced enough such that the amount of carbon put into the
atmosphere by all sources is equal to the amount taken out through
natural feedback
processes.
Here we present a means to estimate this
natural flux
by a separation of oceanic carbon anomalies into those created
by biogenic
processes and those created
by CO2 exchange between the ocean and
atmosphere.
We now recognize more of the
natural climatic variations caused
by the interaction of five highly nonlinear coupled chaotic
processes: earth's
atmosphere, oceans, volcanoes, solar weather, and galactic cosmic rays (Curry 2016, Curry 2017).
GHG's continue to accumulate heat in the
atmosphere from the time they're released to the time they get scrubbed out
by natural processes.
The increase in the
atmosphere is very constant,
by far not looking like any
natural process.
The formation of cloud droplets and cloud ice crystals is associated with suspended aerosols, which are produced
by natural processes as well as human activities and are ubiquitous in Earth's
atmosphere.
Effectively she appears to at least confirm the possibility of my proposition that what is going on is an entirely
natural solar induced
process (destruction of ozone in the upper
atmosphere by more incoming solar protons) which casts doubt on all previous assumptions concerning human CO2 AND CFCs.
The problems begin when human activities distort and accelerate the
natural process by creating more greenhouse gases in the
atmosphere than are necessary to warm the planet to an ideal temperature.
«(6) methane is a powerful greenhouse gas that may be exchanged between terrestrial methane hydrate reservoirs and the
atmosphere by natural or anthropogenic
processes; and
Scientists agree the main cause of climate change is human activities which magnify the «greenhouse effect» — a
natural process in which gases in the
atmosphere warm the Earth
by trapping heat that is radiating towards space (2)(4).
Natural processes in the
atmosphere slowly destroy these non-CO2 GHGs over time, mainly
by oxidation in the troposphere (0 - 20 km high), and
by «photolysis» with UV rays in the stratosphere (> 20 km).
This new concept of anthropogenic impacts on seawater pH formulated here accommodates the broad range of mechanisms involved in the anthropogenic forcing of pH in coastal ecosystems, including changes in land use, nutrient inputs, ecosystem structure and net metabolism, and emissions of gases to the
atmosphere affecting the carbon system and associated pH. The new paradigm is applicable across marine systems, from open - ocean and ocean - dominated coastal systems, where OA
by anthropogenic CO2 is the dominant mechanism of anthropogenic impacts on marine pH, to coastal ecosystems where a range of
natural and anthropogenic
processes may operate to affect pH.
