Will There Be Climate Migrants en Masse?
While some countries are historically responsible for climate change, should the global community take up responsibility for climate migrants, even if they do not cross international borders? Should there be immigration concessions for climate migrants when they need to or have to cross borders? These are important questions that arise at a time of global climate change.
Climate Change and Our Common Future: A Historical Perspective
I saw at one time a leaflet that asked people to come together in stopping climate change. It seems that many are not aware that the climate changes all the time and that the change is not stoppable. Climate changes, however, differ in their timing and magnitude and are a result of many factors, such as the distance between the sun and the equator, which contributes to the heat budget of the Earth, and the difference in the temperature of the equator from that of the cooler poles due to deviations in Earth's orbit, or variations in solar radiation.
Unlayering of the Ozone: An Earth Sans Sunscreen
The formation of the Antarctic ozone hole is a graphic demonstration of how rapidly we can change the atmosphere of our planet. There are many other environmental issues facing us today and we must link them together to understand and debate the underlying causes, rather than treat each issue in isolation.
Greening the Workforce
The challenge of striking a deal in Copenhagen is not underestimated by the representatives of the world of work -- employers, workers and governments -- who come together at the International Labour Organization (ILO). They are aware of the profound changes in production and consumption patterns that a meaningful climate agreement will have. But their message to world leaders and to the negotiators is that they are ready for the challenges of the transformation of enterprises, jobs and employment patterns.
The Pattern of Response to HIV/AIDS and Climate Change – A Commentary
Almost three decades into the HIV/AIDS pandemic, there is still widespread stigma, denial and government inaction. There are reports of rising rates of infection in the Western industrialized nations and concerns about the possibility of explosive epidemics in the Asian block; yet sub-Saharan Africa, with less than 15 per cent of the world's population, remains at the epicentre of the epidemic, with over 70 per cent of the infections worldwide.

A Modest Extension of the Kyoto Protocol Can End the Impasse Between Industrial and Developing Nations
Beyond Carbon Markets
The headlines generated by the carbon trading mechanisms at the heart of the Kyoto Protocol, most notably the Clean Development Mechanism, tell a story of a scheme in trouble. But why has it caused such controversy?
Africa – A Future for Itself
How does Africa intend to deal with climate change and how can it help shape a better future for itself in the face of the coming environmental catastrophe? As concerns grow, the continent will for the first time negotiate under one umbrella in Copenhagen.
A Hypothesis of Hope for the Developing World
About 99 per cent of climate change casualties take place in the developing world. While economic growth and development are priorities in all countries, the needs in developing and least developed countries are on a different scale altogether. Developing countries are constrained by their particular vulnerability to the impacts of fickle weather and climate. The poor in these countries are at a higher risk to future climate change, given their heavy dependence on agriculture, strong reliance on ecosystem services, rapid growth and concentration of population and relatively poor health services.
The True Costs of Conventional Energy
Renewable energy is expensive -- we cannot afford it. I have heard this argument many times over. But those who bring it up are wrong. The costs of renewable energy are not higher than those for conventional energy. Instead people confuse costs with prices and need to be better aware that the market price of conventional energy does not tell the truth.
Biotechnology – A Solution to Hunger?
World hunger and food insecurity is a recurring problem in most parts of the developing world. Among the many potential biotechnologies that are available, and the different ways in which they can be applied, genetic modification (GM) of crops demands particular attention. Genetically modified crops possessing genes from different species, could possibly relieve global food shortages.
