Sentences with phrase «i.e. human greenhouse gas»

A linear warming trend plus natural cycles can be mistaken for a step function, but physically the global warming is caused by an external radiative forcing (i.e. human greenhouse gas emissions).

Not exact matches

Granted, there are more benefits to reducing particulate and greenhouse gas emissions than just climate change, i.e. PM 2.5 which can be stuck in the human lung and cause cancer / respiratory issues, SO2 which contributes to acid rain (we've already eliminated the majority of this problem), as well as soot (nobody wants the surrounding area covered in ash).
Human water vapour emissions are irrelevant, as water vapour is in dynamic equilibrium with ocean water, an equilibrium controlled by global mean temperature, i.e., other greenhouse gases etc..
But the IPCC concerns itself with consideration of anthropogenic (i.e. man - made) global warming (AGW) as a result of emissions of greenhouse gases (notably carbon dioxide, CO2) from human activities.
First, while the early 20th century warming was likely predominantly naturally - caused (i.e. low volcanic activity and increasing solar activity), there was also a significant human contribution as greenhouse gas emissions began to ramp up.
The reduction in nighttime cooling that leads to this bias may indeed be the result of human interference in the climate system (i.e., local effects of increasing greenhouse gases or human effects on cloud cover), but through a causal mechanism different than that typically assumed.
Also, the basic theory behind the scientific argument i.e. increasing greenhouse gases in the atmosphere due to humans burning fossil fuels will lead (and is leading) to global warming which will change the climate, is not being stated often enough in the media.
The largest climate forcing today, i.e. the greatest imposed perturbation of the planet's energy balance [1,2], is the human - made increase in atmospheric greenhouse gases (GHGs), especially CO2 from the burning of fossil fuels.
We support educating the public and policymakers in government and industry about the harmful human health effects of global climate change, and about the immediate and long - term health benefits associated with reducing greenhouse gas emissions (i.e., heat - trapping pollution) and taking other preventive and protective measures that contribute to sustainability.
The solar contribution to recent temperature change is probably minimal and / or negative (i.e., the sun has probably caused cooling, but human increases in greenhouse gasses have overwhelmed that small cooling to cause a net warming).
