I once pointed out to an academic from a developed nation that the emissions resulting from their country's two - car households had been
accumulating in the atmosphere for decades.
They will continue to
accumulate in the atmosphere over the next years and possibly even decades, which together with the inertia of the climate system will support further warming.
The idea behind it is simple: gases
accumulating in the atmosphere as by - products of human industry and agriculture — carbon dioxide, mostly, but also methane, nitrous oxide, ozone, and chlorofluorocarbons — let in the sun's warming rays but don't let excess heat escape.
Unfortunately, these gases — especially CO2 — are
accumulating in the atmosphere at increasing concentrations due to human activities such as the burning of fossil fuel in cars and power plants industrial processes, and the clearing of forests for agriculture or development.
Tacking on industry in general, including producing cement, steel, plastics and chemicals, accounts for 78 percent of greenhouse gases, which
invisibly accumulate in the atmosphere and trap extra heat.
As those gases are expected to
continue accumulating in the atmosphere while aerosols stabilise or fall, that means «dramatic consequences for estimates of future climate change», the scientists agreed in a draft report from the workshop.
Whether the Arctic's 21st - century journey ends with a tipping - point style crash or a whimper remains uncertain, but — even with the current recovery — it's hard to find a researcher probing Arctic ice trends who does not foresee open - water summers, and all that comes with them, in coming decades, as long as greenhouse gases
keep accumulating in the atmosphere.
This, said Ying Sun of the University of Texas at Austin and colleagues, explained why CO2 wasn't
accumulating in the atmosphere quite as fast as climate models predicted it should be.
In my understanding, the temperature gradient is altered by the presence of additional GHGs in such a way that the loss of heat from the ocean is slowed, so OHC, of course, continues to rise as
GHGs accumulate in the atmosphere.
However, any agent with a lifetime shorter than the response time of the physical climate system must be treated in a very different way to CO2, since such emissions do not
effectively accumulate in the atmosphere over multi-decadal time scales.
With the greenhouse gases
already accumulated in the atmosphere, it would take less than 30 years for it to be inevitable that temperature would in time reach 2 °C above the pre-industrial level if the global greenhouse - gas emissions stayed at their current rate.
The conditions stoking the blazes in Southern California are projected to become more common and severe in the years ahead as greenhouse gas pollution from fossil fuel burning, deforestation, farming, and other industrial
practices accumulates in the atmosphere, changing temperatures and rainfall patterns.
