Driving The Climate Change

Driving The Climate Change

1. It is dirve by....

   • The Oceans
     • Warm water colects in one place, evaporation and clouds buildup may increase. Marine organisms consume huge amount of CO2
   • The Water Cycle
     • When evaporation its formed leads to cloud formation, which can have a cooling effect
   • Clouds
     • By reflecting solar energy and warm Earth by up trapping heat being radiated up from the surface
   • The Atmosphere
     • Gases give Earth a temperature. Green-houses gases, watervapor, CO2, and other gases absorb heat energy, then re-rediate a portion of it back on the surface
   • Ice and Snow
     • Bright white expansive of ice and snow reflect sunlight back into space, cooling the planet. Melting sea ice draws heat from the ocean
   • Solar Input
     • Solar energy having travelled miles, hits the upper atmosphere. The rest warms Earth and fueld it´s weather engine
   • Land Surface
     • When solar energy penetrates the land surface it is converted into heat, most of which radiates upward. And it can have major effects on climate.
   • Human Influences
     • The green-house gases, the fuel combustion and the aerosols are the main human activities magnify warming effects

2. Global Temperatura Rising

   • Earth´s surface has risen ahalf degree Celsius in the last past century. Dips and Spikes reflect natural fluctations and short-term events.

3. Green-house effect

   • The atmosphere, only a fraction of that heat makes it directly back into space. Therest is trapped in the lower air layers, which contain a number of gases, that absorb the outgoing infrared radiation. As does gases heat up, some of their warmth radiates back down the surface. With increased heating more evaporation, this creates a powerful feed backloop.

4. Models and Uncertainty

   • The general circulation models consist of equations representing the laws of the atmospheric physics and ocean circulation

5. Missing CO2

   • Oceans
     • Serve as a vast "sink" for CO2. The oceans apparently remove at least 2 billion tons frmo the atmosphere each year
   • Clouds
     • Clouds shade Earth´s surface, promoting cooling, but depending on their altitude, density, and other conditions, they can also trap outgoing heat, promoting warming
   • Human Activity
     • We releases aprox. 7 billion metric tons of CO2 every year.

6. As the World Warms

   • Warming of the magnitude anticipated by the IPCC cloud also prompt widespread calamity. For one thing, it would putmore water vapor into air. Causing more more rainfall worldwide and probably more intense weather generally. The most probable effect is that the averge amount of precipitation in any given event will be greater
