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...

Freshwater stress
Today, the great pressure on water resources is rising human populations, particularly growing concentrations in urban areas. This diagram shows the impact of expected population growth on water usage by 2025, based on t...

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...

Potential dengue transmission in case of temperature rise
A warmer climate increases occasions of vector borne tropical diseases. This figure depicts weeks of potential dengue transmission under current temperature and 2°C and 4 °C warming. Presence of dengue virus, mosquito ve...

Emissions of CO2 - selected countries (1995)
The rich countries of the world historically have emitted most of the anthropogenic greenhouse gases since the start of the industrial revolution in the latter half of the 1700s. Per capita, the significant emissions sti...

Great weather and flood catastrophes over the last forty years
Some reports suggest that increase in climate variability or extremes has taken place in recent decades. However, there are inadequate data to determine whether such global changes have occurred consistently over the 20t...

UN Convention on Climate Change (UNFCCC)
The United Nations Framework Convention on Climate Convention is the foundation of global efforts to combat global warming. Opened for signature in 1992 at the Rio Earth Summit, its ultimate objective is the 'stabilizat...

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 ...

CO2 emissions from land use change
Emissions of carbon dioxide due to changes in land use mainly come from the cutting down of forests and instead using the land for agriculture or built-up areas, urbanisation, roads etc. When large areas of rain forests ...

Six IPCC scenarios
The projection of future climate change depends partly on the assumptions made about future emissions of greenhouse gases and aerosol precursors and the proportion of emissions remaining in the atmosphere.

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...
