Brazilian alcohol transport fleet and regional climate benefits
In Brazil there are noticeable benefits for using alcohol as a fuel over traditional gasoline. This graphic illustrates the reduction in use of fossil fuels (gasoline) in favor of ethanol/alcohol. This has lead to a redu...

Use of renewables and combustible waste for energy production in 2001; Latin America and the Caribbean
Approximately 12 % of the world’s energy supply comes from renewable energy sources (biomass, waste and other renewables, excluding hydropower). The average renewable share in Latin America is higher than the world aver...

Global atmospheric concentration of CO2
Atmospheric CO2 has increased from a pre-industrial concentration of about 280 ppmv to about 367 ppmv at present (ppmv= parts per million by volume). CO2 concentration data from before 1958 are from ice core measurements...

Planets and atmospheres
A planet's climate is decided by its mass, its distance from the sun and the composition of its atmosphere. Mars is too small to keep a thick atmosphere. Its atmosphere consists mainly of carbon dioxide, but the atmosphe...

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 ...

Forest fires in Albania, Macedonia, Montenegro, Serbia and Bulgaria
The summer of 2007 brought another heat wave to the Balkans, with widespread forest fires. The extent of burnt forest may differ a great deal from one year to the next, but it is quite clear that over the past 20 years, ...

Estimated Loss of Rainfall in Amazonia in the Next Century
The synthesis of 23 climate models shows a decline in rainfall between 1980-1999 and 2080-2099 under mid- range (A1B) global greenhouse gas emissions scenarios. The dry season rainfall is particularly important (winter i...
