• The Amazon: a hot spot for biodiversity and climate regulation

  climate regulation mechanism with climate-damaging teleconnections rippling out across the planet. Ten per cent of the world’s biodiversity is thought to exist within this region. How likely is this? But the Amazon basin is already drying out and it has been affected by drought this year with media

• What are the Northern Lights and what causes them?

  causes them? Author: Press Office 30 May 2025 The Northern Lights, or aurora borealis, are one of nature’s most mesmerising displays. This phenomenon can be seen as waves of colour that ripple across the night sky in hues of green, pink, red, and violet. While often associated with the Arctic Circle

Cirrus is of a discontinuous structure and of limited horizontal extent which is the distinction between it and cirrostratus. Dense cirrus patches or tufts of cirrus may contain ice crystals large

In this case, Humberto’s transition from a hurricane to an extra-tropical system was expected to create a ripple in the Jetstream, which in turn would affect the development and track of the next low-pressure system approaching the UK. Even subtle shifts in the Jetstream’s position
