Studies suggest that tropical cyclones are becoming more powerful with the most dramatic increase in the North Atlantic. The increase is correlated with an increase in ocean temperature. A debate concerns the nature of these increases with some studies attributing them to natural climate fluctuations, and others suggesting climate change related to anthropogenic increases in radiative forcing from greenhouse gases.

Costa Rica pioneered the use of the payments for environmental services (PES) approach in developing countries by establishing a formal, country-wide program of payments, the PSA program. The PSA program has worked hard to develop mechanisms to charge the users of environmental services for the services they receive.

The summits of the neotropical Guayana Highlands in Venezuela have a unique biodiversity that is under serious threat because of habitat loss resulting from climate warming. Although conservation studies are urgently needed, these are blocked by official bodies that will not grant permits for fieldwork in the region. (Correspondence)

A unique drilling project in the western Ross Sea has revealed that Antarctica had a much more eventful climate history than previously assumed. A new sediment core hints that the western part of the now-frozen continent went through prolonged ice-free phases

Honey, being a natural product manufactured by honey bees is considered to be free from any extraneous material. The over-reliance on pesticides caused several environmental problems including pesticide residues in food. This constitutes a potential risk for human health, because of their sub acute and chronic toxicity.

Payments for environmental services (PES) have been distinguished from the more common integrated conservation and development projects on the grounds that PES are direct, more cost-effective, less complex institutionally, and therefore more likely to produce the desired results.

Climate-conscious consumers want to cut their carbon footprints. Retailers have responded, initially, labelling air freighted produce with an airplane. But this simplistic strategy hit developing country producers in an unfair way, and today schemes to consider the full carbon lifecycle of goods are underway.

Meeting in Bangkok in early April, climate change negotiators started grappling with key trade related issues, such as intellectual property rights and competitiveness concerns. Delegates also considered the responsibilities that countries could take on in the post-Kyoto climate regime they hope agree on by 2009. India proposed basing future commitments on per capita emissions, which could potentially

More than 20 United Nations development agencies joined the World Bank and the World Trade Organization this week in Bern, Switzerland, to discuss emergency humanitarian aid and other measures to combat the growing world food crisis. The World Food Programme says it needs an extra US$755 million just to meet existing needs for food aid.
