Sentences with phrase «human fossil fuel»

Healthy forests absorb carbon dioxide from human fossil fuel combustion and at the same time reduce regional temperatures.
This is a quantity roughly equivalent to historical human fossil fuel emissions to date.
The basic understanding of greenhouse gas warming, human fossil fuel combustion, and the simple math this article uses to reach the conclusion you don't like is very straightforward.
Many lines of evidence, including simple accounting, demonstrate beyond a shadow of a doubt that the increase in atmospheric CO2 is due to human fossil fuel burning.
Given the massive effect fossil fuel consumption has had on the sulphur cycle and the accompanying addition of SOx NOx and other chemicals to the atmosphere there may be a source of MUCH greater influence on cloud variations, over the timescale of human fossil fuel use and in synchrony with the CO2 changes.
By that time the United Nations had already determined that global warming was a crisis and that human fossil fuel CO2 emissions were the cause.
Favorable energy economics are just one of solar's many benefits — including less water use, lack of requirement for a centralized grid in undeveloped regions, low cost, zero air pollution, and in providing a mitigation for the rising problem of global climate change (which is primarily driven by human fossil fuel burning).
One is CO2 fertilization and the other is N fertilization... either or both could occur and would increase in general at the same time and amount wrt human fossil fuel burning.
This is in direct opposition to the IPCC's contention that global warming is accelerating, and supports arguments that the amount of warming that will occur over the remainder of the 21st century as a result of human fossil fuel usage will be at the low end of the IPCC projections, or even lower.
It has sometimes been argued that the earth's biosphere (in large part, the terrestrial biosphere) may have the capacity to sequestor much of the increased carbon dioxide (CO2) in the atmosphere associated with human fossil fuel burning.
«All this adds up to what scientists expect to be a gradual slowing of ocean CO2 uptake if human fossil fuel use continues to accelerate.»
Over the last three decades, five IPCC «assessment reports,» dozens of computer models, scores of conferences and thousands of papers focused heavily on human fossil fuel use and carbon dioxide and greenhouse gas emissions, as being responsible for «dangerous» global warming, climate change, climate «disruption,» and almost every «extreme» weather or climate event.
They have firmly linked glacial loss to global warming driven by profligate human fossil fuel combustion and they have warned that such loss risks social change and potential catastrophe for millions.
«This is in direct opposition to the IPCC's contention that global warming is accelerating, and supports arguments that the amount of warming that will occur over the remainder of the 21st century as a result of human fossil fuel usage will be at the low end of the IPCC projections, or even lower,» the two scientists added.
Science tells us undeniably that human fossil fuel consumption is rapidly warming the planet.
No matter how well informed you are, no matter how many peer - reviewed studies you cite, or how many times you point out the overwhelming agreement based on the evidence that exists among climate scientists that global warming is real and is principally caused by human fossil fuel use, you will get no where.
One climate doomsday scenario (among many) that continues to have no basis in climate science reality is the infamous prediction that Gaia will soon have a Venus - like atmosphere and boiling oceans... because of humans fossil fuel use.
Next, Doney (p. 1512) reviews how the chemistry of the oceans is changing, mostly due to human fossil fuel combustion, fertilizer use, and industrial activity.
What the outsize footprint means in physical terms is that the world does not have enough forests to soak up all the excess CO2 from human fossil fuel — burning and other activities.
Nor do they accept repeated research indicating the overwhelming consensus among credential climate scientists that human fossil fuel use is the primary driver of unnatural global warming — in fact Heartland's staff have repeatedly lied to cast doubt upon that research.
Most of these perturbations, tied either directly or indirectly to human fossil fuel combustion, fertilizer use, and industrial activity, are projected to grow in coming decades, resulting in increasing negative impacts on ocean biota and marine resources.
If you accept that carbon dioxide is a greenhouse gas and that human fossil fuel use is now the dominant contributor to atmospheric CO2 changes, then knowing how much global temperatures respond to increased greenhouse gases in the atmosphere is important for understanding the future climate.
Overall, they find that by far the largest radiative forcing over the past 250 years comes from the increased greenhouse effect, which we also know is due to human fossil fuel combustion (Figure 3).
1) Basic physics - human fossil fuel combustion has increased the greenhouse effect, causing a global energy imbalance, which the planet responds to by warming.
Nor do they accept repeated research indicating the overwhelming consensus among credential climate scientists that human fossil fuel use is the primary driver of unnatural global warming — in fact Heartland's staff have repeatedly lied to cast doubt upon that research.
Human fossil fuel use is also behind a general warming trend in the oceans observed over the past 50 years that increases the resistance to CO2 uptake.
