  • 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.

  • 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.

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 order to attract the best engineers of each generation to one of the most urgent fields of engineering development we must embed understanding not just of the challenges, but the opportunities, within the collective consciousness of the public through the mass media. We must design a career path that is desired by young professionals, accredited by institutions and that will afford recognition and esteem. We must develop university courses that will excite and entice students to address the challenge of creating a low carbon world.
