Radiative forcing - energy balances and the greenhouse effect Radiative forcing - energy balances and the greenhouse effect
Radiative forcing is the change in the balance between radiation coming into the atmosphere and radiation going out. A positive radiative forcing tends on average to warm the surface of the Earth, and negative forcing tends on average to cool the surface. The figure shows estimates of the globally and annually averaged anthropogenic radiative forcing (in Wm-2) due to changes in concentrations of greenhouse gases and aerosols from pre-industrial t...

Greenhouse effect Greenhouse effect
Human activities are causing greenhouse gas levels in the atmosphere to increase. This graphic explains how solar energy is absorbed by the earth's surface, causing the earth to warm and to emit infrared radiation. The greenhouse gases then trap the infrared radiation, thus warming the atmosphere.

Population by income level Population by income level
The rich world consumes more and thus produces more waste. The World Bank classification based on gross national income per capita is an indication of the global consumption level. Over the last two decades the world as a whole did not get any richer but China and Indonesia, two densely populated countries, entered the 'middle income world', as defined by the World Bank. Consumer items are available to a growing number of individuals, particular...

BedZED (Beddington Zero energy development), location BedZED (Beddington Zero energy development), location
At Beddington, south of London, a housing development known as BedZED (Beddington Zero energy development) was designed from the start to produce little waste of any sort. It was built on a depolluted plot of land, previously used by industry, and recycled materials were used in its construction.

Energy production waste in selected European countries Energy production waste in selected European countries
Waste is a major environmental concern for the energy sector. Depending on the type of energy, the production process itself will generate substantial quantities of waste. The energy sector generates specific types of waste: waste from mining and upgrading coal and lignite (tailing); waste from oil and gas refining; combustion waste from thermal power stations; waste from air-pollution abatement devices and fi nally the components of the power st...

Energy production, consumption and export - Kazakhstan and Azerbaijan Energy production, consumption and export - Kazakhstan and Azerbaijan
The land-based activities of the oil and gas industry in Kazakhstan and Azerbaijan have had a much more severe impact on the environment than marine activity. In particular the growth in hydrocarbon-related activity has destroyed the environmental balance of whole areas throughout the region.

Emissions and energy scenarios by source Emissions and energy scenarios by source
Despite the Kyoto protocol and increased concern over the consequences of climate change, world wide emissions of CO2 continues to grow. According to the International Energy Agency (IEA) world total CO2 emissions will increase by 62% from 2002 – 2030. More than two-thirds of the increase will come from developing countries. They will overtake the OECD as the leading contributor to global emissions early in the 2020s. Despite the strong increase ...

Russia emissions of greenhouse gases (CO2, CH4, N2O) 1990 and 2010 projections Russia emissions of greenhouse gases (CO2, CH4, N2O) 1990 and 2010 projections
Emissions from human activities, and primarily fossil fuels, contribute to climate change, global warming and the greenhouse effect. This is primarily from industry, energy, transportation and related sectors. Please note that this collection of graphics has since been updated, please see http://www.grida.no or http://unfccc.int/ for the latest information and graphics
