Vital Climate Change Graphics Temperature trends and projections The global average surface temperature has increased over the 20th century by about 0.6 degrees Celsius. This increase in temperature is likely to have been the largest for any century in the last 1000 years. Evidence from tree ring records, used to reconstruct temperatures over this period, suggests that the 1990s was the warmest period in a millennium. It is very likely that nearly all land areas will warm more rapidly than the global average, ... The Interactive UK Energy Consumption Guide An interactive data visualisation case study looking into the UK's energy consumption from 1970 to 2010. By Evo Energy Show More Fossil fuels Fuels such as coal, oil and natural gas were formed over millions of years from organic matter like plankton, plants and other life forms. Over time, sand, sediment and rock buried the organic matter and it eventually formed large quantities of fuels. These underground resources, known as fossil fuels, are still the primary fuel source for electricity, heating and powering vehicles around the globe. Five main fossil fuels Coal is a combustible black or brown organic sedimentary rock. It’s mostly carbon and is typically found as layers (coal beds) or veins (coal seams).

Learn how you can recycle or reuse your older model when you upgrade. CSIRO - Cape Grim CO2 Data Cape Grim Baseline Air Pollution Station Cape Grim, on Tasmania’s west coast, is one of the three premier Baseline Air Pollution Stations in the World Meteorological Organization-Global Atmosphere Watch (WMO-GAW) network. Baseline stations are defined by the WMO to meet a specific set of criteria for measuring greenhouse and ozone depleting gases and aerosols in clean air environments. These baseline stations are crucial points of reference for the larger global network of atmospheric gas observing stations. The Cape Grim Baseline Air Pollution Station monitors Southern Hemispheric air.

Life-cycle assessment Life-cycle assessment (LCA, also known as life-cycle analysis, ecobalance, and cradle-to-grave analysis)[1] is a technique to assess environmental impacts associated with all the stages of a product's life from-cradle-to-grave (i.e., from raw material extraction through materials processing, manufacture, distribution, use, repair and maintenance, and disposal or recycling). LCAs can help avoid a narrow outlook on environmental concerns by: Compiling an inventory of relevant energy and material inputs and environmental releases;Evaluating the potential impacts associated with identified inputs and releases;Interpreting the results to help make a more informed decision.[2] Life Cycle Assessment Overview Goals and purpose[edit] The goal of LCA is to compare the full range of environmental effects assignable to products and services in order to improve processes, support policy and provide a sound basis for informed decisions.[3]

Fossil Fuels Fossil fuels: Energy from fossilised organic materials Custom Search How it works: Earth's Inconstant Magnetic Field Earth's Inconstant Magnetic Field Our planet's magnetic field is in a constant state of change, say researchers who are beginning to understand how it behaves and why. Every few years, scientist Larry Newitt of the Geological Survey of Canada goes hunting. He grabs his gloves, parka, a fancy compass, hops on a plane and flies out over the Canadian arctic. Not much stirs among the scattered islands and sea ice, but Newitt's prey is there--always moving, shifting, elusive. His quarry is Earth's north magnetic pole.
