IPCC terms WHS
IPCC terms to know WHS
| Term | Definition |
|---|---|
| IPCC | 1,200+ climate scientists from around the world who compile existing climate research; part of the UN |
| anthropogenic | Caused by humans |
| unequivocal | without doubt; complete confidence |
| mitigation | to reduce the severity |
| quantifiable | can be measured (as opposed to qualitative, which is descriptive) |
| confidence | measure of accuracy |
| robust | strength of data, based on quantity and precision |
| ocean surface salinity | amount of salt at the ocean's surface |
| ocean acidification | decrease in pH due to absorbtion of CO2 by ocean; CO2 + H2O = H2CO3 (carbonic acid) |
| sea ice | forms from the edge of land out over ocean; sea ice is fresher than ocean water |
| glacier | ice formation on land |
| irreversable | cannot be reversed |
| RCP - Representative Carbon Pathway | possible future scenario of CO2 emissions; based on statistical analysis of population and consumption trends |
| permafrost | thick subsurface layer of soil that remains frozen throughout the year, occuring mainly in polar regions |
| mid-latitude regions | halfway between equator and poles; continental US would be considered mid-latitude |
| high latitude regions | areas nearest the poles; the Artctic and Antarctice |
| Arctic | Area around the North pole; Polar bears live here; |
| Antarctic | area around the South pole; actual continent with large glaciers and extensive sea ice |
| precipitation intensity | shorter storms which dump more water at once instead of spreading out the precipitation over longer periods; likely to increase flooding |
| greenhouse effect | Radiant energy from the sun bounces off darker surfaces of Earth. Energy is transformed into infrared energy which is trapped by greenhouse gases. |
| albedo effect | Radiant energy bounces off ice or snow and is not trapped by greenhouse gases. |
