Not exact matches
The most common indicator is the atmospheric background CO2 concentration, the global mean temperature, the global mean sea level, and the area with snow or Arctic sea ice.
Climate alarm depends on several gloomy assumptions — about how fast emissions will increase, how fast atmospheric concentrations will rise, how much global temperatures will rise, how warming will affect ice sheet dynamics and sea - level rise, how warming will affect weather patterns, how the latter will affect agriculture and other economic activities, and how all climate change impacts will affect public health and welfare.
With global GHG emissions and concentrations continuing to increase; with climate change intensifying changes in ecosystems, ice sheet deterioration, and sea level rise; and with fossil fuels providing more than 80 % of the world's energy, the likelihood seems low that cooperative actions will prevent increasingly disruptive climate change over the next several decades.
«It is very likely that the rate of global mean sea level rise during the 21st century will exceed the rate observed during 1971 — 2010 for all Representative Concentration Pathway (RCP) scenarios due to increases in ocean warming and loss of mass from glaciers and ice sheets.
Using a statistical model based on winter near - global sea surface temperatures, Tivy shows high concentrations of ice remaining throughout the NWP region.
Based on proxy records from ice, terrestrial and marine archives, the LIG is characterized by an atmospheric CO2 concentration of about 290 ppm, i.e., similar to the pre-industrial (PI) value13, mean air temperatures in Northeast Siberia that were about 9 °C higher than today14, air temperatures above the Greenland NEEM ice core site of about 8 ± 4 °C above the mean of the past millennium15, North Atlantic sea - surface temperatures of about 2 °C higher than the modern (PI) temperatures12, 16, and a global sea level 5 — 9 m above the present sea level17.
The IPCC 2007 Fourth Assessment of climate change science concluded that large reductions in the emissions of greenhouse gases, principally CO2, are needed soon to slow the increase of atmospheric concentrations, and avoid reaching unacceptable levels.However, climate change is happening even faster than previously estimated; global CO2 emissions since 2000 have been higher than even the highest predictions, Arctic sea ice has been melting at rates much faster than predicted, and the rise in the sea level has become more rapid.
We are pleased to announce that the High Latitude Level 3 Global AMSR Sea Ice concentration product is operational since March 16th 2017.
Higher methane concentrations in the atmosphere will accelerate global warming and hasten local changes in the Arctic, speeding up sea - ice retreat, reducing the reflection of solar energy and accelerating the melting of the Greenland ice sheet.
The second set of simulations, referred to as Tropical Ocean - Global Atmosphere (TOGA) experiments, are forced with observed SSTs for the 30 ° N — 30 ° S domain only, while SSTs and sea ice concentrations outside of the domain are set to climatology.
The first set of simulations, referred to as Global Atmosphere - Global Ocean (GOGA) experiments, are forced with prescribed SST and sea ice concentrations from the observational datasets of Hurrell et al. (2008) for 1979 — 2008, with different initial conditions for each ensemble member.
For both hemispheres combined, then, the addition of about 65 ppm of atmospheric CO2 concentration since 1979 has apparently had no overall effect on global - scale sea ice trends.
As Media Matters has noted, the IPCC's 2007 «Synthesis Report» concluded that» [w] arming of the climate system is unequivocal, as is now evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice and rising global average sea level» and that» [m] ost of the observed increase in global average temperatures since the mid-20th century is very likely [defined in the report as a» > 90 %» probability] due to the observed increase in anthropogenic [human - caused] GHG [greenhouse gas] concentrations.»
They also ran atmospheric models that used observed global sea surface temperatures, Arctic sea ice conditions and atmospheric carbon dioxide concentrations in 2010 to assess whether such factors might have contributed to the heat wave.
methane concentrations have been increasing in the atmosphere... but NASA do not include it among their 5 indicators of Global Warming (Sea Level, Arctic Sea Ice, Atmospheric CO2 Concentration, Global Surface Temperature, Ozone Hole).
