Media playback is unsupported on your device UK scientists head to Greenland this week to trial new sensors that can be placed under its 2km-thick ice sheet.
The instruments are designed to give researchers unique information on the way glaciers slide towards the ocean. Dubbed "Cryoeggs", the devices will report back on the behaviour of the meltwaters that run beneath the ice. This water acts to lubricate the flow of glaciers, and in a warmer world could increase the volume of ice discharged to the ocean. This would push up global sea levels - potentially by as much as 7m, if all the ice on Greenland were to melt. Scientists want to understand how fast the process could unfold. "Our models have done a fantastic job so far in building a picture of what might happen, but they've essentially been working blind because we have so little data from the bed of the Greenland ice sheet," said Dr Liz Bagshaw from Cardiff University.

Textbooks featuring diagrams of the Earth’s water cycle breed a "false sense of security" about the sustainability of water, academics have warned.
A team of international experts said the classic diagram used in geography and science lessons needed updating to show the effect of human interference. Primary: The art project opening pupils’ eyes to climate change Labour: Make climate change core part of curriculum Opinion: The climate strikes show 'Generation Snowflake' is tougher than we thought A study published in Nature Geoscience, with an additional comment in Nature, showed that in a sample of more than 450 water cycle diagrams in textbooks, scientific literature and online, 85 per cent showed no human interaction at all with the water cycle. Only 2 per cent of the images made any attempt to connect the cycle with climate change or water pollution. In addition, nearly all the examples studied depicted verdant landscapes, with mild climates and abundant freshwater.

*****Water cycle / Carbon cycle: Resource WJEC Educational Resources Website. Theconversation. The Indus is one of Asia’s mightiest rivers.
From its source in the northwestern foothills of the Himalayas, it flows through the Indian state of Jammu & Kashmir and along the length of Pakistan to the Arabian Sea. The river and its five tributaries together make up the Indus Basin, which spans four countries and supports 215m people. Yet fast-growing populations and increasing demand for hydropower and irrigation in each country means the Indus is coming under intense pressure. India and Pakistan, the two main countries in the basin, divided up rights to the various tributaries under the Indus Water Treaty of 1960 (IWT). The IWT has survived various wars and other hostilities between the two countries, and as such it is largely considered a success. For instance, India recently fast-tracked approval for several major dams along the Chenab, a 900km-long tributary of the Indus that was originally allotted to Pakistan under the IWT.
