Energy and sustainable development at global environmental summits

Energy and sustainable development at global environmental summits

Table of Contents

Introduction

The 2002 World Summit on Sustainable Development (WSSD) was the most recent of a series of attempts to deal holistically with global environmental issues by holding high-profile, multi-issue policy summits. The last thirty years of such summitry have not only yielded a rapidly expanding global environmental agenda but have also witnessed a noteworthy evolution in the policy framing of global environmental issues.

The first of these mega-meetings, held at Stockholm, Sweden, in 1972, was called the United Nations Conference on the Human Environment (UNCHE) and dealt with – as its name rightly suggests – a rather small set of issues that were most directly related to the ‘human environment’. Twenty years later, a far more elaborate agenda came under discussion at Rio de Janeiro, Brazil, when the more ambitiously titled United Nations Conference on Environment and Development (UNCED) sought to radically expand the global agenda by moving well beyond the merely environmental and seeking to establish ‘environment and development’ as the central policymaking framework. By 2002, in Johannesburg, South Africa, the concept of ‘sustainable development’ which had already begun to assume salience at Rio gained further centrality not only by being incorporated into summit’s title but also by becoming the key motivator of the expanded Johannesburg agenda, which now included such issues as sanitation, HIV/AIDS and poverty eradication.

If this evolution – from a policy framework principally rooted in ‘environmental’ concerns to one imbedded in the broader and more integrated notion of ‘sustainable development’ – is to be anything more than rhetorical it should be reflected not only in the titles of the major conferences but also in how particular issues are tackled at these summits. This paper will review one such issue, energy, in terms of a) how it relates to sustainable development at a conceptual level; and b) whether there is any noticeable difference in how it was treated at the three major global environmental summits, in particular, at WSSD./.../

Before the Big Bang


More Thoughts (and now math!) On What Came Before the Big Bang

Physicist Sean Carroll gave a wonderful talk at the June 2008 American Astronomical Society meeting about his "speculative research" on what possibly could have existed before The Big Bang. (Here's an article about Carroll's talk.) But now Carroll and some colleagues have done a bit more than just speculate about what might have come before the beginning of our Universe. Carroll, along with Caltech professor Marc Kamionkowski and graduate student Adrienne Erickcek have created a mathematical model to explain an anomaly in the early universe, and it also may shed light on what existed before the Big Bang. "It's no longer completely crazy to ask what happened before the Big Bang," said Kamionkowski.

This day in history
Max Planck's Quantum Theory is Born (1900)
Considered the inventor of quantum theory, Max Planck shocked the science world by showing that atoms emit or absorb energy in bundles, or quanta, not in a continuous stream as taught by Newtonian physics. This insight, along with subsequent developments by Einstein, Bohr, and others, established the revolutionary quantum theory of modern physics and earned Planck the 1918 Nobel Prize in Physics. In 1945, Planck's son was executed following a failed attempt to assassinate what political figure?

MADRID, Spain, Nov. 26 -- The number of biologic agents for rheumatoid arthritis has increased in recent years, but the best results come from more effective use of available treatments, researchers found.
Action Points  
  • Explain to patients who ask that although newer drugs for rheumatoid arthritis have improved treatment since 2000, better management of treatment, including use of older drugs such as methotrexate, proved more important than specific drugs.

Disease activity scores decreased, independent of the availability of new therapies, both in patients with severe and milder disease, Isidoro González-Alvaro, M.D., of the Hospital de la Princesa in Madrid, and colleagues reported in Arthritis Research and Therapy.

TNF antagonists and Leflunomide (Arava) have shown efficacy in randomized controlled trials, not only controlling disease activity but also slowing or arresting radiological damage, the researchers wrote.

However, they said, when used outside of clinical trials, the effectiveness of new drugs may differ, in part because clinical-trial patients are generally younger, have less comorbidity, and show greater disease activity than real-life patients./.../
