The phrase
"to reach the atmosphere" means to go up high into the air, at a level where our planet's gases and weather are found.

The power plant proposal will prevent about 430 million tons of carbon dioxide
from reaching the atmosphere, based on the 30 percent figure and what power plants have already reduced since 2005.
Surprisingly, very little of the methane gas rising up through the sea appears to
reach the atmosphere in the summer.
These clouds vary with the intensity of cosmic
rays reaching the atmosphere and act like a shade in the global greenhouse to control temperature.
CCS is an emerging suite of science and technologies designed to capture carbon dioxide from power plants and store it underground, preventing greenhouse gases
from reaching the atmosphere.
Scientists have found that ancient reservoirs of methane do
not reach the atmosphere due to a role played by ocean waters.
«We (and others) have seen
CH4 reaching the atmosphere from seafloor sources, notably on the East Siberian Arctic shelf, and smaller amounts elsewhere.
Most methane hydrates are buried in ocean water so deep that the journey through the water column is too far for the gas to
ever reach the atmosphere, according to Ed Dlugokencky, a researcher at the National Oceanic and Atmospheric Administration.
Furthermore, the data reveal that the methane - derived carbon was mixed from the surface ocean downward, suggesting that a significant fraction of the initial dissociated hydrate
methane reached the atmosphere prior to oxidation.
But according to the report, water droplets started by salt that
reaches the atmosphere grow by attracting these smaller, pollution - initiated drops.
Now, a new study suggests that one such «coronal mass ejection» in 2015 temporarily weakened Earth's protective magnetic field, allowing solar plasma and radiation from the same storm to more
easily reach the atmosphere, potentially posing a danger to astronauts.
(Methane forms as a by - product of anaerobic bacterial decomposition of organic matter in the soil and
reaches the atmosphere through the roots and stems of the rice plants.)
Brazil has been recognized as a leader in global efforts to reduce deforestation and associated greenhouse gas emissions — mostly due to the successful implementation of forest conservation policies that reduced deforestation in the Amazon by 80 % below historical levels, and prevented more than 5 billion tons of CO2 from
reaching the atmosphere over the last decade.
Exponentially less methane would be able to
reach the atmosphere in waters that are thousands of feet deep at the very edge of the shallow seas near continents, which is the area of the ocean where the bulk of methane hydrates are,» Sparrow says.
As it does so, it oxidises to CO2, dissolving in seawater or
reaching the atmosphere as CO2 which causes far slower warming, but can nevertheless contribute to ocean acidification.
The study observed active methane plumes rising from the seabed, but most of the gas was not from hydrates and much of it did
not reach the atmosphere.
In places where methane is produced, such as wetlands, methanotrophs consume huge quantities of methane before they
ever reach the atmosphere.
Apart from preserving the national park, UNDP said the preservation will keep more than 400 million tons of harmful emissions
from reaching the atmosphere.
It remains to be seen whether such abrupt and massive methane release could have
reached the atmosphere.
But so far, as Dickens says, no one has shown that quantities of methane large enough to change the climate would
reach the atmosphere.
By preventing carbon dioxide from
reaching the atmosphere, CCS can help slow global warming and is recognized as a key technology to meet the Paris Climate Agreement.
The commercial turbine burns coal, the dirtiest of fossil fuels, but it traps nearly all the resulting carbon dioxide underground before
it reaches the atmosphere.
Although the researchers did not examine in this study what prevents methane released from the seafloor from
reaching the atmosphere, they suspect it is biodegraded by microorganisms in the ocean before it hits the surface waters.
However, methane only acts as a greenhouse gas if and when
it reaches the atmosphere — a scenario that would occur only if the liberated methane travelled from the point of release at the seafloor to the surface waters and the atmosphere.
One reason is to prevent nitrogen - cutting «solutions» from causing inadvertent problems; for example, when manure is treated to prevent nitrogen from reaching coastal waters, the molecule can become more likely to
reach the atmosphere and cause trouble there.
Undersea volcanoes could not produce this effect because the dust and aerosols would be absorbed by the sea before
they reached the atmosphere.
An important question is how that coal bed gas is
reaching the atmosphere.
Perhaps most importantly, from a climate perspective, some of the revenue could be used to buy back any carbon produced from energy consumption that was successfully captured and sequestered before
it reached the atmosphere.
