A logging site at Nesset, Mau Forest, Kenya. Humans are clearing  a net 10 billion trees a year from the surface of the Earth.

The Earth fairly bristles with trees, with new research showing it has an estimated 3.04 trillion of them. Although this is almost 10 times more than(...)

Researchers at Maynooth University may have discovered a way to switch off the development of Type 2 diabetes in people who are overweight. It blocks (...)

Beavers are consummate dam builders, blocking rivers to create ponds and surrounding wetlands. Leaves, branches and other carbon-rich material builds up on the floor of the ponds, rotting to release methane, a greenhouse gas much more powerful than carbon dioxide. Photograph: Thinkstock/Getty

Efforts to retrieve the beaver from near extinction have met with great success - so much so that the animals have now become major polluters. The pon(...)

As Prof Noel Caplice describes it, a revolutionary new system that avoids putting patients through heart bypass operations was literally a “back-of(...)

Carbon dioxide levels increased by 2.2 parts per million during the year, putting average levels for the 12 months at 393.1 parts per million. This is a staggering 141 per cent above the pre-industrial level of 278 parts per million, the report said.

The levels of greenhouse gases in the Earth’s atmosphere have continued their relentless rise, according to figures just released in Geneva by the (...)

Higher temperatures mean more moisture and more energy to be released. Ireland also lies under a region where these filaments pass overhead and so we too face this increased risk of flooding. Photograph: Cyril Byrne

Our weather is going to take a turn for the worse in the coming years as the climate warms and rainfall amounts increase. It will lead to more storms (...)
