  • Forest ecosystems cover large parts of the terrestrial land surface and are major components of the terrestrial carbon (C) cycle. Most important, forest ecosystems accumulate organic compounds with long C residence times in vegetation, detritus and, in particular, the soil by the process of C sequestration. Trees, the major components of forests, absorb large amounts of atmospheric carbon dioxide (CO2) by photosynthesis, and forests return an almost equal amount to the atmosphere by auto- and heterotrophic respiration.

  • Carbon offsets are an innovative tool for allowing companies and individuals to reduce greenhouse gas emissions beyond what they can easily achieve on their own. In the past two years, interest in carbon offsets has grown dramatically as companies and concerned consumers have sought ways to help mitigate climate change. However, the global market for voluntary carbon offsets is currently unregulated, which has led to growing concerns about whether buyers are really getting what they are paying for.

  • But there is another potential impact for the environment and nature conservation which is a much more positive one. The 1999 structural fund regulations for the first time recognised that the funds could be used for the protection and improvement of the environment (emphasis added). This change in wording was extremely significant – for the first time the doors were open to local and regional authorities and national governments to start putting forward environmental and nature programme proposals which meet the European Union’s cohesion policy objectives set out in the Treaty.

  • Scientists predict the earth is facing 40-to-60 years of climate change, even if emissions of carbon dioxide and other global warming gases stopped today. One inevitable consequence of the greenhouse gases already in the atmosphere will be an increase in the frequency and severity of natural disaster events. Global Warming, Natural Hazards, and Emergency Management documents the imperative need for communities to prepare for the coming effects of climate change and provides a series of in-depth, road-tested recommendations on how to reduce risks for communities and businesses.

  • The environmental science of ecology is the study of the relationship of plants andanimals to their physical and biological environment. The physical environment includeslight and heat or solar radiation, moisture, wind, oxygen, carbon dioxide, nutrients in soil,water, and atmosphere. The biological environment includes organisms of the same kindas well as other plants and animals.

  • IN CHAPTER 5 WE DISCUSSED plants’ requirements for mineral nutrients and light in order to grow and complete their life cycle. Because living organisms interact with one another and their environment, mineral nutrients cycle through the biosphere. These cycles involve complex interactions, and each cycle is critical in its own right. Because the amount of matter in the biosphere remains constant, energy must be supplied to keep the cycles operational. Otherwise increasing entropy dictates that the flow of matter would ultimately stop.

  • The Review takes an international perspective. Climate change is global in its causes and consequences, and international collective action will be critical in driving an effective, efficient and equitable response on the scale required. This response will require deeper international co-operation in many areas - most notably in creating price signals and markets for carbon, spurring technology research, development and deployment, and promoting adaptation, particularly for developing countries. ...

  • In later eras, new materials have been closely associated with radical change. The development of paper was as important as the printing press in revolutionising communications. The introduction of gunpowder into Europe transformed warfare. In more modern times, gas lighting only became demonstrably superior to oil and candles with the introduction of the gas mantle, composed of novel materials such as thorium and cerium oxides. A hundred years ago electric filament lamps were made possible by other novel and fairly unusual materials, osmium and tungsten.
