Sentences with phrase «part by human emissions»

While the greenhouse effect is undeniably real, and while most scientists agree that there has been a rise in global temperatures caused in some part by human emissions of carbon dioxide, no one knows how much more warming will occur this century or whether it will be dangerous.

Not exact matches

Suffice it to say that there are indications that at least a major part of the current sea ice retreat is due to naturally occurring shifts in weather patterns, rather than simply to Arctic swarming caused by human GHG emissions, as some people apparently believe.

Luntz insists that Americans would support a cap on carbon emissions — 80 percent of Dems, but also 43 percent of Republicans he surveyed are either definitely or pretty sure climate change is a problem that's caused in part by humans.

Scientists in the US say parts of Australia are being slowly parched because of greenhouse gas emissions — which means that the long - term decline in rainfall over south and south - west Australia results from fossil fuel burning and depletion of the ozone layer by human activity.

The Advisory Board shall recommend changes to offset methodologies, protocols, or project types, or to the overall offset program under this part, to ensure that offset credits issued by the Administrator do not compromise the integrity of the annual emission reductions established under section 703, and to avoid or minimize adverse effects to human health or the environment.

As it so happens, there were significant human GHG emissions in the early 20th Century, which caused atmospheric CO2 levels to rise from 300 to 310 parts per million by volume (ppmv) from 1910 to 1945.

This is so because in addition to the theological reasons given by Pope Francis recently: (a) it is a problem mostly caused by some nations and people emitting high - levels of greenhouse gases (ghg) in one part of the world who are harming or threatening tens of millions of living people and countless numbers of future generations throughout the world who include some of the world's poorest people who have done little to cause the problem, (b) the harms to many of the world's most vulnerable victims of climate change are potentially catastrophic, (c) many people most at risk from climate change often can't protect themselves by petitioning their governments; their best hope is that those causing the problem will see that justice requires them to greatly lower their ghg emissions, (d) to protect the world's most vulnerable people nations must limit their ghg emissions to levels that constitute their fair share of safe global emissions, and, (e) climate change is preventing some people from enjoying the most basic human rights including rights to life and security among others.

The carbon dioxide that is building in the atmosphere, at least in part, gets there through human emissions of carbon dioxide that are the by - product of burning fossil fuels (coal, oil, natural gas) to produce the vast majority the energy that has powered mankind's industrial and technical ascent since the Industrial Revolution.

It has long been observed that temperatures in cities are higher than in the surrounding countryside, caused, in part, by human structures that reduce albedo and evapo - transpiration, as well as by the effects of waste heat emissions, McCarthy et al 2010.

Of the total CO2 mass, some extra part is removed, equal to about halve the human emissions, partly by less natural emissions and partly more natural sinks.

WASHINGTON (AP)-- If carbon dioxide emissions continue at their current pace, by the end of century parts of the Persian Gulf will sometimes be just too hot for the human body to tolerate, a new study says.

That's Why the Cause of Global Warming is a Fundamental Concern If global warming is only part of a greater climatic fluctuation, perhaps partially influenced by human activity, then there is less need to address human - caused carbon emissions.

It seems to me that a rational agenda on the part of climate alarmists should either be to disprove the Wallace et al. studies or to implement actions that would carry out the conclusions suggested by the research (most importantly, abandoning efforts to reduce human - caused emissions of CO2).

Approximately 55 % of human CO2 emissions currently remain airborne (the remainder is absorbed by carbon sinks), and each 7.8 Gt CO2 emitted corresponds to roughly 1 part per million by volume (ppmv) increase in atmospheric CO2 concentration.

The inertia in the climate system is not in the physics of the system, but rather in the rate of human emissions, determined in part by our investments in plant and infrastructure, investments that have an effect on our energy systems for decades.
