Sentences with phrase «net emitters»

IMO to lump all the natural mechanisms in as one is not valid unless there is good evidence that no component (s) of these are net emitters..

Only for the planet as a whole, instantaneously at various intervals, provided you are looking from far enough away from Earth, (like maybe from mars), to homogenize the areas that are net absorbers with the areas that are net emitters.

It is a recent discovery that the oceans can act for decades at a time as net absorbers OR net emitters of previously accumulated solar energy on a vast and highly variable scale yet AGW proponents still ignore the overwhelming evidence because to acknowledge it would destroy years of fond memories of a publicly funded gold rush encouraged by their fanciful claims to understand climate and be in a position to influence it.

Over the longer term the sun varies (there is uncertainty as to how much) and in the medium term the oceans vary much more than we previously thought possible in that they can act as net absorbers or net emitters of previously acquired solar energy for decades at a time.

Few studies have placed reservoir GHG emissions into such a context, but those that have find that reservoirs result in a net carbon footprint that exceeds that of the preflooded landscape and that they are net emitters of CO2 equivalents (Jacinthe et al. 2012, Teodoru et al. 2012, Faria et al. 2015).

The highest net emitters are 3rd world countries.

In time, as the temperature rises, even the oceans may become net emitters as the warmer upper layers lose their capacity to hold the carbon dioxide which they have already absorbed.

Now, in a perverse twist, a new study shows that in a few years, the pests will have turned the once climate - friendly forests into net emitters of carbon dioxide.

Ponds and lakes play a significant role in the global carbon cycle, and are often net emitters of carbon gases to the atmosphere.

As exciting as these wildlife changes have been, Hey notes that potentially more important is a change in the environment's chemistry — a change that has turned the wetland from a net emitter of nitrates to an eliminator of these pollutants.

Fires are a major source of carbon emissions in the Amazon, and scientists are beginning to worry that the region could become a net emitter, instead of a carbon sink.

At the same time, beetle damage and drought have devastated Canada's boreal forests, causing it to slip into being a net emitter of carbon, as decaying wood releases carbon to the atmosphere.

Baltic state lobbied for flexibilities in EU rules to enable a dramatic increase in forestry, turning its thriving woodland into a net emitter of carbon by 2030

Speaking of which, the mountain pine beetle infestation in British Columbia is projected to cause that province to become a net emitter of CO2 within a decade or two.

Second, even if and when the ocean becomes a net emitter of CO2, that will be because of human - caused warming, not some natural phenomenon.

Here's an article which indicates that soon, the nature will not be a net absorber (if it even is at the moment), but will be a net emitter of GHGs.

The ocean will first have to cease being a net absorber of CO2 before it can become a net emitter of CO2.

However each natural component, over the given time period (e.g. multiple of years to eliminate seasonal effects), must either be a net emitter, net sink or neutral.

Baltic state lobbied for flexibilities in EU rules to enable a dramatic increase in forestry, turning its thriving woodland into a net emitter of carbon by 2030

Their results showed that the forest's ability to store more carbon dioxide than it emitted had weakened over the last few years - to the point where it has now become a net emitter of carbon.

Not exact matches

Also, dealing with the forests as a «carbon sink,» deforestation and other factors may have rendered trees as a net carbon emitter, rather than a sink.

While Savory's obviously over optimistic, grasslands, depending on how they're farmed, can be either a net carbon sink or emitter, ditto for forests.

But a net carbon sink may become a net carbon emitter — or it may be weakened so that it is no longer acting all that effectively as a carbon sink.

«the tendency to a radiative equilibrium means that the emitter with the higher surface temperature will loose energy due to a negative net radiation balance until this net radiation balance becomes zero.»

It clearly states that (a) emission of energy by radiation is accompanied with cooling of the surface (if no compensating changes prevent it), and (b) the tendency to a radiative equilibrium means that the emitter with the higher surface temperature will loose energy due to a negative net radiation balance until this net radiation balance becomes zero.

Vaughan, I am sure that you appreciate that ideal biofuels are net zero emitters due to their growth taking in CO2.

We process engineers who have to get the sums right use the term «operational emissivity» to specify how much net IR energy is transferred relative to a black body emitter.

There is also has a second stream for the largest emitters, that is to say emitters that produce over 400,000 tonnes of emissions or for brand new facilities like new near zero or net zero manufacturing processes or Carbon Capture and Utilization projects.

We don't really know which farms and forests are net absorbers or emitters.

It is counterintuitive for ACO2 to be so different from natural CO2 to the extent that there is no or little capacity for sinks to reabsorb the human emissions; it is also problematic that there should be a situation where temperatures have slightly increased and yet the ocean remains a net absorber and not emitter of CO2.

Gerlich and Tscheuschner, despite their apparent mastery of the mathematics of radiative transfer, don't know the difference between gross and net radiative flux, and they are apparently unaware of the concept of causality in an Einsteinian framework — a molecule of CO2 emitting a photon in a random direction can't know if there is a (cooler or warmer) surface in the direction of emission until time has elapsed for the photon to travel to the surface and back, and has no mechanism to remember from one photon to the next whether there was a source of photons in that direction, or what the apparent temperature of the emitter was.

As a result of the thawing permafrost, the land switched from a carbon sink (net CO2 absorber) to a carbon source (net CO2 emitter) decades earlier than it would have otherwise — before 2100 for every DEP.
