atmospheric physics
The sun's angle from the vertical or solar zenith angle, is determined by the latitude, time of year, and time of day. In the Northern Hemisphere, the sun shines directly overhead at noon at the Tropic of Cancer on the first day of summer, at the equator on the ...

carbon cycle
Scientists are actively investigating the carbon cycle to see if their data does indeed indicate a balancing of the cycle. These types of investigations have led many scientists to believe that the forests of the Northern Hemisphere are, in fact, absorbing 3.5 Gt C per year, and so changing land use is actually removing carbon from the ...

CRU Information Sheet no. 5: The Millennial Temperature Record
UK and USA have begun producing spatial reconstructions of past temperatures and estimates of average temperatures for the Northern Hemisphere (NH). Figure 1 shows several of these series for the NH for the millennium. Evidence for the Southern Hemisphere is increasing also, but only about 5% of available proxy series come from this hemisphere. How do these ...

Climate Ark: Climate Change Overview
Precipitation changes: trend over land from 1900 to 1994 Precipitation has increased over land at high latitudes of the Northern Hemisphere, especially during the cold season. Decrease in precipitation occurred in steps after the 1960s over the subtropics and the tropics from Africa to Indonesia. 16. Sea level rise due to global warming Over the last 100 ...

David Suzuki Foundation: Climate change : Science of Climate Change
And it has already begun - global average temperature has risen by 0.6 degrees Celsius since 1900, and the northern hemisphere is substantially warmer than at any point during the past 1000 years. Burning fossil fuels such as coal, oil and gas is largely responsible for climate change. Deforestation and modern intensive farming methods also contribute to the ...
