Sentences with phrase «with higher carbon dioxide emissions»

The observatory's location in Hawaii was chosen specifically due to the cleanliness of the air that produces more accurate measurements than what would be measured close to areas with higher carbon dioxide emissions.

In the new study, McGuire and his colleagues used simulations to study changes in permafrost and carbon storage in the northern permafrost region from 2010 to 2299 using two climate change scenarios: One with low carbon dioxide emissions and one with high carbon dioxide emissions.

Count on a higher degree of engagement this time around, especially with a hike in fuel - economy and carbon - dioxide - emissions reductions equivalent to 62 mpg (3.9 L / 100 km) on the table.

Many studies have demonstrated the risks that ocean acidification pose to marine organisms, such as coral dissolving in more acidic water.6 However, new findings suggest that the August and September time period could be particularly challenging for the earliest life stage of elkhorn coral — an important reef - forming coral of the Caribbean — if we continue on a path of high carbon dioxide emissions.5 Ordinarily each August or September elkhorn corals flood the water with eggs and sperm (gametes) for sexual reproduction.2

Specimens of elkhorn coral living in water with excess carbon dioxide have been studied for fertilization rates, ability of larvae to settle on reef substrate (where they produce new corals), and subsequent growth and survival.3 Three levels of carbon dioxide were tested, corresponding to concentrations today, at mid-century, and at the end of the century on a high - emissions path.3, 5 At the mid-century concentration, the ability of fertilization to occur and for larvae to settle successfully on the reef was significantly reduced: around 52 percent, and the decline intensified to about 73 percent at the late - century concentration.3 The corals» ability to survive over the long run declined as well, by an average of 39 percent and 50 percent respectively.3, 4

The United States — which accounted for a good third of the Annex I countries» emissions of carbon dioxide in 1990 and has the world's highest emissions per capita — abandoned the protocol in 2001, with the excuse that it excluded 80 per cent of the world's population and would, moreover, be detrimental to the US economy.

With carbon dioxide levels shooting up to unprecedented levels, it is high time we group together for a concerted action against the huge amounts of climate - change - inducing emissions from fires in Hell.

China produced 6,200 million metric tons of carbon dioxide last year, compared with 5,800 million tons for U.S. CO2 emissions in China are now 7.5 percent higher than in America, whereas last year China's emissions lagged 2 percent behind those of the U.S., which faces a slowing economy.

Thawing permafrost also delivers organic - rich soils to lake bottoms, where decomposition in the absence of oxygen releases additional methane.116 Extensive wildfires also release carbon that contributes to climate warming.107, 117,118 The capacity of the Yukon River Basin in Alaska and adjacent Canada to store carbon has been substantially weakened since the 1960s by the combination of warming and thawing of permafrost and by increased wildfire.119 Expansion of tall shrubs and trees into tundra makes the surface darker and rougher, increasing absorption of the sun's energy and further contributing to warming.120 This warming is likely stronger than the potential cooling effects of increased carbon dioxide uptake associated with tree and shrub expansion.121 The shorter snow - covered seasons in Alaska further increase energy absorption by the land surface, an effect only slightly offset by the reduced energy absorption of highly reflective post-fire snow - covered landscapes.121 This spectrum of changes in Alaskan and other high - latitude terrestrial ecosystems jeopardizes efforts by society to use ecosystem carbon management to offset fossil fuel emissions.94, 95,96

Carbon dioxide emissions associated with burning coal are the greatest of any fossil fuel, and coal has the highest carbon content among all unburned fossil fuel reserves.

Primary energy demand until 2035, from «Facing China's Coal Future», figure 1, page 7, Increases in carbon emissions by fuel type for regions with highest absolute emissions growth, 2008 - 2035 from IEO2011, figures 115, page 143, and «Cumulative carbon dioxide emissions by region», figure 116, also on page 143, same link as above.

Because of the combination of high absorption, a regional distribution roughly aligned with solar irradiance, and the capacity to form widespread atmospheric brown clouds in a mixture with other aerosols, emissions of black carbon are the second strongest contribution to current global warming, after carbon dioxide emissions.

The dwindling do - nothing crowd likes to cite the high cost of complying with the Kyoto Protocol, which is supposed to cut carbon dioxide emissions of the industrialized nations that ratified it.

The report also shows that Texas has by far the highest total emissions from power plants and refineries, with 294 million metric tons of carbon dioxide equivalent spewed into the atmosphere.

With the Golden State's headlong rush toward lower carbon - dioxide emissions and greater use of renewables, the energy poverty figure is surely much higher today.

• Won a key 2007 victory on greenhouse gas vehicle emissions when the nation's highest court sided with our coalition and struck down the Environmental Protection Agency's refusal to regulate carbon dioxide as a pollutant under the Clean Air Act.

These changes to the ocean are directly linked to anthropogenic carbon dioxide (CO2) emissions, with current atmospheric CO2 levels approximately 30 % higher than over the last 2 Myr [6].

This is set to rise steadily higher — yet it is being imposed for only one reason: the widespread conviction, which is shared by politicians of all stripes and drilled into children at primary schools, that, without drastic action to reduce carbon - dioxide emissions, global warming is certain soon to accelerate, with truly catastrophic consequences by the end of the century — when temperatures could be up to five degrees higher.
