21 - Rising Temperatures

Set 1 www.climatefresk.org 21 La temperatura promedio del aire en la superficie de la Tierra ha aumentado en 1.2 ° C desde 1900. Posibles escenarios de emisiones futuras predicen que este aumento alcanzará entre 1.5 ° C y 5 ° C para 2100. Durante la última edad de hielo, hace 20,000 años, la temperatura promedio del aire era 5 ° C más baja que la actual y el calentamiento tardó 10,000 años.

Energy Budget

As mentionned on card 21, this is the temperature of the air, above ground, in average on the Earth.

Consequences

Disruption of the Water Cycle

Rising Temperatures


Terrestrial Biodiversity

Rising Temperatures


Decline in Agricultural Yields

Rising Temperatures

In northern countries, a little increase in temperature can lead to better yields, but in southern countries, it's the contrary: Any degree warmer is a decrease in yields.

Other possible consequences

Vectors of Disease

Rising Temperatures

The vectors of disease card is generally linked to the Terrestrial Biodiversity card because disease vectors are a sub-part of biodiversity, but it can also be linked to the same causes as the biodiversity card, i.e. Disruption of the Water Cycle and Rising Air Temperatures.
