Scientists have produced evidence showing dramatically that the current temperature rise there is highly unusual. For most of the last two thousand years, the Arctic slowly cooled, a consequence of variations in the Earth’s orbit.

But over the last century, the cooling abruptly reversed, and the region is now warmer than at any time in the 2,000-year record. Writing in the journal Science, the researchers say this shows how quickly the Arctic responds to climatic changes.

News item 2

The international conservation group, WWF, has accused European toilet and tissue paper manufacturers of contributing to global deforestation by not using enough recycled material. A spokesman said more than a quarter of a million trees were in fact being flushed down toilets or discarded as rubbish each day.

The report found alarmingly low levels of recycled fibers in the vast majority of products and said the fibers were instead being taken from natural forests in South Africa, Asia, Europe and across the Americas. Using virgin forest to make toilet paper, says the report, is wasteful and unnecessary. The report also warns that illegal and unsustainable logging and conflicts over land rights still exist in many of these areas and that all but on of the companies have so far failed to take effective measures to prevent illegal or controversial timber from being used in their products.
