Emissions fluctuate slightly during the year and are highest in spring and summer.

«Many of California's water managers are now working with projections of a one foot rise by mid-century and a three to four foot rise by 2100, slightly above the levels projected in the higher emissions scenarios of the Intergovernmental Panel on Climate Change (IPCC)...»

This is slightly higher than the IPCC's estimate under the same emissions scenario of 7 cm by 2100.

Fuel economy of 56.5 mpg is on par with a comparable X1, although the Mercedes» slightly higher CO2 emissions put it one tax bracket higher for company car drivers.

The Police Interceptor engine calibration includes a slightly higher idle speed (by approximately 40 rpm) and minor changes in the emissions settings.

This is an all new engine, and also uses BMW's TwinPower Turbo technology, or basically variable turbine geometry which allows the engine to put out slightly higher power (about 7 - 8 bhp more), but still reduces consumption (and emissions) by 17 % according to manufacturer data.

A 185 bhp 2.3 - litre light pressure turbo engine replaces the 170 bhp unit in the 9 - 5 range; this delivers improbed acceleration, better fuel economy, lower emissions and a slightly higher top speed.

This leads to slightly higher than normal emissions.

So it is quite likely that plant photosynthesis (including that happening in the ocean from phytoplankton) could well be constrained by CO2 concentration at 280 ppmv, with a slightly higher input from animal respiration plus emissions from the Earth's interior balancing out the natural decay rate.

Was this «decay rate» offset in the past by slightly higher animal respiration than plant photosynthesis, plus unknown CO2 emissions from submarine volcanoes and fissures in Earth's crust?

N2O emissions from zero till were slightly higher or similar to conventional till during the growing season.

Thus the 2020 GHG emissions limit established in response to AB 32 is now slightly higher than the 427 MMTCO2e in the initial Scoping Plan.»

The only exception is in 2030, where countries acutely vulnerable to climate change will have slightly higher average emissions than those in the severe category (2030: severe = 48.83 mtCO2e, acute = 103.13 mtCO2e).

To project future emissions from human activities, we used the SRES higher (A1FI) and lower (B1) emissions scenarios that capture to some extent the uncertainty in future climate due to human decisions [22], with CO2 emissions ranging from slightly less than present - day levels up to four times present - day levels by 2100.

It is reasonable to assume that human CO2 emissions will continue to grow at a slightly higher level than population, despite the fact that there is considerable pressure on fossil fuels (economic as well as environmental) and the carbon efficiency of all nations is continuously improving (especially in the developed nations).

«When open burning emissions, which emit high levels of organic matter, are included in the total, the best estimate of net industrial - era climate forcing by all short - lived species from black - carbon - rich sources becomes slightly negative -LRB--0.06 W / m2 with 90 % uncertainty bounds of -1.45 to +1.29 W / m2).

A higher bio-diesel portion generally leads to slightly elevated nitrogen oxide emissions with simultaneously clearly reduced particulate mass emissions, which can be explained with the higher oxygen portion in the fuel among other things.

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

This is slightly higher than the IPCC's estimate under the same emissions scenario of 7 cm by 2100.

In fact the CO2 increase has been roughly linear since the 1950's, with the 1993 - 2010 rate only slightly higher than the preceding years, while our emissions have seen strongly nonlinear growth.

6 Today's high - income countries (per capita income of $ 20,000 or more) are responsible for slightly less than half of all CO2 emissions.

The infrared radiation hangs around longer than it would have done, some being absorbed by matter, causing heating, which causes higher re-emission (the blackbody spectrum of the whole Earth's emissions moves slightly to a higher energy - temperature profile, in order to balance out the radiation budget of the Earth).

It is because so little energy is being used, and because alternatives are ruled out ab initio (the model contains no nuclear power, and no technology for storing away carbon emissions from fossil fuels; natural gas prices rise strongly and coal plants are retired well before they are clapped out) that the model ends up with such a high percentage of renewables; indeed given the premise it's slightly surprising it doesn't end up with even more.
