If you live in a coastal zone and have looked at maps of future sealevel rise or have read about how climate change could be slowed with policy changes to reduce emissions, youve likely seen these scenarios in action. Four RCP scenarios describe different levels of radiative forcing in the atmosphere by 2100.
While temperatures provide a measure of the Earth’s climate, it is even better to use the global sealevel , which provides a far more reliable measure. The global sealevel acts like the mercury in a thermometer because warmer water expands.
If people everywhere stopped burning fossilfuels tomorrow, stored heat would still continue to warm the atmosphere. Picture how a radiator heats a home. Water is heated by a boiler, and the hot water circulates through pipes and radiators in the house. The radiators warm up and heat the air in the room.
The ocean has already absorbed 90% of the heat trapped by greenhouse gases and 26% of the carbon dioxide emitted by humans burning fossilfuels. Warmer water also expands and raises sealevels as well as holds less oxygen. So, we’re seeing the ocean heat up, lose oxygen and get bigger.
The Altiplano plateau in western Bolivia has some of the world’s highest and most consistent levels of solar radiation, creating a high potential for solar photovoltaic power in the region, but structural challenges may prevent scaling.

Albedo The amount of solar radiation reflected from an object or surface, often expressed as a percentage. Carbon Dioxide A naturally occurring gas, and also a byproduct of burning fossilfuels and biomass, as well as land-use changes and other industrial processes. compressed natural gas, solar, hydroelectric, wind).
While the main focus has been on operational activities in Antarctica, global warming caused by fossil-fuel burning by these (and other) countries has left Antarctica on the brink of irreversible change. In the Arctic this has led to regional warming four times faster than the global average.
Warmer temperatures will encourage the melting of glaciers, ice fields, summer Arctic sea ice, and permafrost, some of which may be irreversible. Sealevels will continue to rise throughout the 21st century, contributing to more frequent and severe coastal flooding in low-lying areas along coasts around the world.
Fossilfuel : Any mineralized formerly organic material extracted from the ground and used in energy production: coal, natural gas, oil. Greenhouse gas : A group of gases known to be responsible for increasing the “greenhouse effect” - that is, gases that absorb infrared radiation and increase atmospheric density.
JDB: Cities have dense concentrations of asphalt, cement and other surfaces that absorb solar heat during the day and radiate it back into the environment. For example, Phoenix is taking heat mitigation seriously by establishing one of the first heat mitigation and response offices at the municipal level.

Most big environmental groups United States who take money directly from people that made their money in fossilfuels have budgets around 100 million a year, my budget is less than a million. Michael: Well, I mean, what — do you think we're helpless to sealevel rise? And they have a huge sea wall that floats up.
