Sentences with phrase «atmosphere over a short period»

Wildfires in Indonesia have been known to release massive amounts of carbon into the atmosphere over short periods of time.

This could be random variation of the atmosphere over a short period, or random measurement error, or some combination.

Not exact matches

Bowen and colleagues report that carbonate or limestone nodules in Wyoming sediment cores show the global warming episode 55.5 million to 55.3 million years ago involved the average annual release of a minimum of 0.9 petagrams (1.98 trillion pounds) of carbon to the atmosphere, and probably much more over shorter periods.

Scientists now think that massive volcanic activity, in a Large Igneous Province called the Siberian Traps, raised air and sea temperatures and released toxic amounts of greenhouse gases into the atmosphere over a very short period of time.

Methane has a relatively short life in the atmosphere where it oxidizes into CO2 over a period of 9 - 15 years.

GHG continue to increase in amounts in the atmosphere and as such, over time more warming inevitably continues though there may be breaks for short periods, and some cooling, as already discussed at great length regarding aerosols.

Methane has a relatively short life in the atmosphere where it oxidizes into CO2 over a period of 9 — 15 years.

Despite this higher cumulative total, the green curve has a higher peak warming than the yellow curve because its emissions are put into the atmosphere over a shorter time period.

This time period is too short to signify a change in the warming trend, as climate trends are measured over periods of decades, not years.12, 29,30,31,32 Such decade - long slowdowns or even reversals in trend have occurred before in the global instrumental record (for example, 1900 - 1910 and 1940 - 1950; see Figure 2.2), including three decade - long periods since 1970, each followed by a sharp temperature rise.33 Nonetheless, satellite and ocean observations indicate that the Earth - atmosphere climate system has continued to gain heat energy.34

The short - term change in surface temperature over the 2000 - 2010 period is a result of ocean heat being exchanged with the atmosphere (via ENSO).

«A reduction in the rate of warming (not a pause) is a result of short - term natural variability, ocean absorption of heat from the atmosphere, volcanic eruptions, a downward phase of the 11 - year solar cycle, and other impacts over a short time period,» Cleugh says.

When you say «we're» cooling now, you must mean the troposphere over some short period of time and certianly less heat is flowing from ocean to atmosphere during the current cool PDO.

Methane has a restricted lifetime in the atmosphere, measured in decades, but while present in the air it has a greenhouse effect some 25 times that of CO2 over a 100 - year period and higher values over shorter periods.

The data and the statistical analysis does not provide the evidence that the so called «pause», a time period with a lower trend estimate than the longer - term trend estimate, was more than just a short - term fluctuation around the median warming trend, mostly due to short - term unforced internal variability in the Earth system (and some contribution from decreasing solar activity and increased reflecting aerosols in the atmosphere, counteracting the increased greenhose gas forcing to some degree), like the «acceleration» over the 16 - year period from 1992 to 2007 (e.g., UAH trend: 0.296 + / - 0.213 (2 sigma) deg.

A. Weather — condition of the bottom layer of the earth's atmosphere in one place over a short period of time B.

But some scientists argue that the impact of methane gas should be calculated over a shorter time period, because methane degrades quickly, and because gas drilling releases large quantities of methane into the atmosphere all at once, likely concentrating and amplifying the effect.
