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.

Loss of habitat is the greatest threat to biological diversity, and 85 per cent of the species on the 2006 Norwegian red list are threatened by changes in habitat. Highly-specialized species appear to be the most vulnerable. The polar bear is one such species, and the extent and sustainability of sea ice is essential for its survival. The global population of polar bears consists of roughly 20,000-25,000 individuals spread between 19 sub-populations.

When it comes to the subject of energy in the Middle East, we instinctively think of oil -- the black gold that has been the source of stable and healthy economies in the region. Nevertheless, this is about to change. With the lead up to the United Nations Climate Change Conference in Copenhagen, Governments are realizing the imminent threat of climate change, and that there is no choice but to act fast.

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 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.

While not on the front line of climate solutions, recycling of waste materials, wastewater, and wasted energy is a locally available and highly desirable means of reducing greenhouse gases. One potent greenhouse gas, the methane emitted from landfills and wastewater, accounts for about 90 per cent of greenhouse gas emissions from the entire waste sector

For centuries, rural communities in the high plateaus of the Andes have utilized water from melting glaciers that typify this amazing mountain range. But the retreat of these glaciers is forcing the communities to reconsider their livelihoods and ways to adapt. From a wider perspective, the melting of glaciers is an iconic warning to the larger cities in the Andes that rely on glaciers for potable water.

On 10 December 2008, the United Nations led worldwide celebrations to commemorate the sixtieth anniversary of the Universal Declaration of Human Rights. Six decades ago, the international community affirmed that the strength of shared ideas and a common vision of respectful and peaceful coexistence could prevail over brutality, hatred and destruction.

Poverty reduction is the greatest challenge facing humanity today. An ideological commitment to reduce or eradicate this phenomenon should be contemplated as part and parcel of social moral responsibility and shared human values across countries and generations. Failure to do so will have unprecedented repercussions on human development.

We live in an age of wonders. From nano-surgery to space stations, networking sites to solar cells, Internet start-ups to smart capital, the world is a more connected, attractive and safe place than was dreamed possible, even fifty years ago.
