Historical trends in carbon dioxide concentrations and temperature, on a geological and recent time scale Historical trends in carbon dioxide concentrations and temperature, on a geological and recent time scale
The most recent geological history, in the last hundred thousand years, has been characterised by cycles of glaciations, or ice ages. The historic temperatures, through these times, have been low, and continental ice sheets have covered large parts of the world. Through ancient air, trapped in tiny bubbles in the Antarctic ice, we have been able to see what the temperature cycle was at that time, and also the concentration of carbon dioxide (CO2)...

Increases in annual temperatures for a recent five-year period, relative to 1951-1980 Increases in annual temperatures for a recent five-year period, relative to 1951-1980
Warming is widespread, generally greater over land than over oceans, and the largest gains in temperatures for the planet are over the North American Arctic, north central Siberia, and on the Antarctic Peninsula. These recent increases in temperature are confirmed by changes in other features: loss of sea ice, shift of tundra to shrub vegetation, and migration of marine and terrestrial ecosystems to higher latitudes.

Solid waste management cost for selected cities Solid waste management cost for selected cities
As garbage piles up, however much space we set aside for landfill, we are beginning to realise that producing waste at this rate is no longer viable. It is time for the three “Rs”: Reduce, Reuse, Recycle and integrated waste management. Waste management strategies are as diverse as waste itself. But whatever we do there is no escaping the “waste of waste” (unless we rein in our greed and buy less).

Environmental policy responses Environmental policy responses
This graphic shows the general responses to the need for policy from region to region around the world. The trend looks optimistic that many different types and level of policies are being implemented in most areas of the world. Please note that this graphic is outdated.

Losses in windstorm catastrophes Losses in windstorm catastrophes
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

Natural and industrial disasters Natural and industrial disasters
Some places are more prone to disaster than others. But that does it take to turn a cyclone into a disaster in one place and just a climatic event somewhere else? The main reasons are obvious enough. Economically deprived people living in shacks are more likely to suffer from any calamity. Rich countries may have more to lose financially, but they also have more resources for anticipating hazards. There are many ways of determining vulnerability,...

Human impact, year 2032 (policy first scenario) Human impact, year 2032 (policy first scenario)
The GLOBIO-2 model is based on settlements and modern infrastructure such as roads, powerlines and pipelines. This map presents the possible situation in 2032, using the GEO-3 policy first scenario. This scenario suggests that decisive initiatives are taken by governments in an attempt to reach specific social and environmental goals.

Human impact, year 1700 (approximately) Human impact, year 1700 (approximately)
The GLOBIO-2 model is based on settlements and modern infrastructure such as roads, powerlines and pipelines. This map presents the situation as it could have been before the advent of industrialization, with very little impact and fragmentation. The main human impact at this stage would have been the conversion of land, primarily in Europe.

Human impact, year 2032 (sustainability first scenario) Human impact, year 2032 (sustainability first scenario)
The GLOBIO-2 model is based on settlements and modern infrastructure such as roads, powerlines and pipelines. This map presents the possible situation in 2032, using the GEO-3 security first scenario. This scenario suggests a new environment and development paradigm emerging in response to the challenge of sustainability, supported by new, more equitable values and institutions.

Official Development Assistance in 2004 Official Development Assistance in 2004
Official development assistance, or foreign aid, consists of loans, grants, technical assistance and other forms of cooperation extended by governments to developing countries. A significant proportion of official development assistance (ODA) is aimed at promoting sustainable development in poorer countries, particularly through natural resource conservation, environmental protection and population programs. (from environmentalindicators.com) Th...
