Sentences with phrase «much smaller concentrations»

For example, the direct radiative effect of a mass of methane is about 84 times stronger than the same mass of carbon dioxide over a 20 - year time frame [22] but it is present in much smaller concentrations so that its total direct radiative effect is smaller, in part due to its shorter atmospheric lifetime.
It is also in much smaller concentrations, measured in ppb not ppm.
Lab spectrometry results show that CO2 is also a GH gas, but it only exists in much smaller concentration in our atmosphere.

The mere presence of filter feeders as large as Tamisiocaris suggests that Cambrian ecosystems were much more productive than previously recognized, the researchers contend: As seen in modern species as diverse as fish, sharks, and whales, large animals can successfully exploit small prey only when they can be sieved from the environment in great concentrations.

The fund can have termed «high risk» because unlike most ELSS funds that follow a multi-cap approach with a relatively safe large - cap bias, the large cap exposure in Reliance Tax Saver for the past two years has been 30 to 40 percent with a much higher concentration in small and mid-caps.
Northern hemisphere concentrations are a bit higher than they are in the Southern hemisphere (here), but the magnitude of the difference is small enough to support the conclusion from the methane budget that tropical wetlands, which don't generate much interhemispheric gradient, are a dominant natural source (Kirschke et al 2013).
The concentration of HCO3 — goes up a bit, but there is so much HCO3 — that the relative change in HCO3 — is smaller than the changes are for CO2 and CO32 -.
Global - scale variations are therefore much smaller, and they reflect changes in global climate drivers, for example in greenhouse gas concentrations or in solar activity.
In particular, the authors find fault with IPCC's conclusions relating to human activities being the primary cause of recent global warming, claiming, contrary to significant evidence that they tend to ignore, that the comparatively small influences of natural changes in solar radiation are dominating the influences of the much larger effects of changes in the atmospheric greenhouse gas concentrations on the global energy balance.
More than half of India's population lives in areas where the average concentration of small airborne particles, known as PM 2.5, are much higher than considered safe, causing increased rates of lung and heart disease.
It is certainly much smaller than the radiative forcing associated with anthropogenic increases in GHG concentration
Methane that escapes the sea is generally a small fraction of methane that is released from clathrates at the sea floor, though if the concentration rose high enough so much could make it to the atmosphere that the impact of methane as a GHG in air (before it devolves to CO2 in air) overwhelmed the negative effects of methane decomposing to CO2 in the oceans..
A reduction to surface layer pH of only 0.1 (which is much too small to be detectable) would induce more than all the change to atmospheric CO2 concentration of 290 ppmv to ~ 400 ppmv which has happened since before the industrial revolution.
Salby apparently finds a much stronger correlation between changes in CO2 concentrations and global temperature plus (to a smaller extent) soil moisture, although he cited no source of data in his lecture.
Gavin (correctly) points out that if a relatively small temperature change of the past century caused the observed 115 ppm change in CO2 concentration, then much larger changes in past global temperature (e.g., glacial / interglacial temperature changes) ought to have caused swings in CO2 of 500-1000 ppm.
