To illustrate, Fig. The scientists modeled the effect of greenhouse gas emission reductions on changes in the Earth's climate from 1850 to 2500 and created projections of global temperature and sea level rises. If greenhouse gas emissions continue apace, Greenland and Antarctica’s ice sheets could together contribute more than 15 inches of global sea level rise by 2100. “If we do not stop greenhouse gases from rising further, especially CO 2, large regions of … In 2019, the concentration of carbon dioxide — the most abundant greenhouse gas — in the atmosphere passed levels not seen for millions of years, and has continued to rise throughout 2020. A focus on the 21st century thus fails to provide a complete picture of the consequences of anthropogenic greenhouse gas emissions on future sea-level rise … Running head: GREENHOUSE GASES 2 Greenhouse Gases and Sea Level Introduction Seas have absorbed heat from greenhouse gases that have been poured into the atmosphere. The loss of large areas of ice on the surface could accelerate global warming because less of the sun's energy would be reflected away from Earth to begin with (refer back to our discussion of the greenhouse effect). The gases that contribute to the greenhouse effect include water vapor, carbon dioxide (CO2), … In response to greenhouse gas warming, sea level is expected to rise due to the thermal expansion of sea water as the ocean warms. Three primary factors of the changes in sea level are thermal expansion, melting glaciers, and loss of Greenland and Antartica's ice sheets. The 'greenhouse effect' is the warming of climate that results when the atmosphere traps heat radiating from Earth toward space. “Well-understood physics tells us that the increasing levels of greenhouse gases are heating Earth’s surface, melting ice and accelerating sea-level rise,” Tans said. Because the deep ocean will warm much more slowly than the upper ocean, the thermally driven rise in sea level is expected to continue for centuries after atmospheric CO 2 stops increasing. In computer-based models, rising concentrations of greenhouse gases produce an increase in the average surface temperature of the earth over time. If greenhouse gas emissions continue apace, Greenland and Antarctica's ice sheets could together contribute more than 15 inches (38 centimeters) of global sea level rise - and that's beyond the amount that has already been set in motion by Earth's warming climate. The Process: Take the required photos and complete all parts of the assignment (calculations, data tables, etc.). Initially, the rise in sea level would only be an inch or two. The industrial slowdown due to the COVID-19 pandemic has not curbed record levels of greenhouse gases which are trapping heat in the atmosphere, increasing temperatures and driving more extreme weather, ice melt, sea-level rise and ocean acidification, according to the World Meteorological Organization (WMO). Greenhouse Gases and Sea Level Rise Laboratory [WLO: 3] [CLOs: 1, 3, 5] This lab enables you to create models of sea level rise resulting from melting of sea ice and glacier ice and examine the effects of this potential consequence of climate change. Read More >> Certain gases in the atmosphere resemble glass in a greenhouse, allowing sunlight to pass into the 'greenhouse,' but blocking Earth's heat from escaping into space. The Global Monitoring Laboratory (GML) of the National Oceanic and Atmospheric Administration conducts research that addresses three major challenges: greenhouse gas and carbon cycle feedbacks, changes in clouds, aerosols, and surface radiation, and recovery of stratospheric ozone. Rising temperatures may produce changes in precipitation patterns, storm severity, and sea level. Collectively, this is … An immediate result of melting glaciers would be a rise in sea levels.
