Sentences with phrase «masked by the aerosol»

How about BAU with carbon dioxide buildup partially masked by aerosol - induced global dimming, building climate crisis leading to a major economic recession?

Then there is stated to be another 0.5 C warming being masked by aerosol pollution, principally in Asia that will clear as they hopefully clean up their air.

The team found that 74 percent of the warming that occurred during 1964 to 2010 was indeed masked by the aerosol cooling effect.

However in John's recent weekly news (28 Dec) the 3rd article (Climate change 2013: Where we are now - not what you think) contained - «The new IPCC report tells us that half of warming (57 %) that should have already occurred has been masked by aerosols mostly emitted since the turn of the century in rapidly developing Asian nations (yes, warming would double if cooling smog pollutants were suddenly cleaned up in Asia).»

Consider that currently we are at approximately 1/2 of one doubling since pre-industrial levels now (ignoring other gases), and that delta T is 0.8 DegC, 0.6 DegC estimated still to come from the thermal lag of the oceans, and some warming having been masked by aerosols.

Not exact matches

The amount of warming caused by CO2 might have been masked over the years by accompanying aerosol emissions.

The observed amount of warming thus far has been less than this, because part of the excess energy is stored in the oceans (amounting to ~ 0.5 °C), and the remainder (~ 1.3 °C) has been masked by the cooling effect of anthropogenic aerosols.

In addition to those blasts of aerosol and the dance of the wrist, viewers will be rewarded by looking as well for the ways in which Solomon would mask off certain forms within the painting.

This has been partly masked by a negative human aerosol forcing so far, but that masking will likely become smaller as more people will demand cleaner air.

Research by an international team of scientists recently published in the journal Geophysical Research Letters says that the cooling effect of aerosols is so large that it has masked as much as half of the warming effect from greenhouse gases.

This is a peer reviewed paper by respected scientists who are saying that aerosol forcing means that the majority of the warming caused by existing co2 emission has effectively been masked thus far, and that as aerosols remain in the atmosphere for far shorter a duration of time than co2, we will have already most likely crossed the 2 degree threshold that the G8 politicians have been discussing this week once the cooling effect of aerosols dissipate.

Probably this effect is usually masked by variations in anthropogenic, volcanic or biogenic aerosols, and is revealed only in Antarctica where other signals are quiet.

There is a nice article in GRL by Kyle Armour and Gerard Roe on the interplay of aerosol masking and climate sensitivity.

Steve 440 says: «A recent paper by Douglas and Christy seems to claim that either 2C02 would lead to less than 1C or if 2C02 leads to greater than 1C then some forcing other than aerosols must be «masking» CO2's effect....»

By comparing this with only the GHG forcing of 3 W m - 2 (90 per cent interval of 2.6 - 3.6 W m - 2), it is seen that aerosols in ABCs have masked 20 — 80 per cent of GHG forcing in the past century.

Aerosol emissions associated with fossil fuels are masking approximately 1/2 of the total energy imbalance experienced by planet earth.

The observed temperature hasn't risen that much because aerosol cooling parameters are postulated by climate modellers which alledgedly mask the «real effect».

Less cooling from aerosols means there is less masked warming waiting in the wings for when the skies are eventually cleaned by pollution regulation.

This is said to be, by AGWers, because aerosols were masking the true trend.

Hmmm... don't suppose it occurred to anyone to check the amount of anthropogenic aerosols that were emitted during this time frame 1940 - 1970, or the fact that aerosols have an immediate cooling effect on troposphere temperatures that can mask the underlying warming caused by the CO2 emissions that also accompany the aerosols.

This is because the net warming it reports includes the cooling effects of aerosols which partly masks the warming caused by greenhouse gases.

(d) Cowtan & Way (2013); England et al. (2014); Santer et al (2014); and Rosenfeld (2014); all provide solid evidence that the current mean global temperature has been masked by such causes as: limited data; the negative phase of the PDO cycle; volcanoes, and aerosols, respectively.
