Ask a scientist

Hi there, I wonder if you can help me. I have to do a geography project on a cold environment and discuss how people, animals and plants adapt, how the seasons change and affect the people and how the environment affects the future of the region. I am in year 8 of secondary school. I […]

Interesting writing about West Antarctica. I’m interested also about West A and PIG. I read somewhere that Greenland icemass has gravitational effect drawing  water 20-30 cm higher than normally. So , if all that ice would melt, sea water would not rise in northern areas but in southern areas more. Is that true and does

Asked by Alyssa Hi Alyssa, Antarctica is a protected environment, and the Protocol on Environmental Protection to the Antarctic Treaty was signed in 1991. However, Antarctic environments are still threatened by several things: Climate change resulting in melting glaciers and ice shelves; People transporting invasive species in like rats or deer on ships; Environmental damage caused

Asked by John Global Warming is the slowly increasing long term average mean annual air temperature of the world. Instrumental records worldwide record this increase in temperatures. However, this warming has a significant effect on our climate. It doesn’t just get warmer; different places warm at different rates. Changes in ocean and atmospheric circulation means

Asked by Richard In short, yes, they are melting! East Antarctica gains some snow, but for more is lost each year by the West Antarctic and Antarctic Peninsula ice sheets. The overview In more detail, the story of melting glaciers in Antarctica is a complex one. Overall, the Greenland and Antarctic ice sheets are melting

Asked by Elli I am an A Level student studying geography. I have recently taken up an EPQ (extended project qualification) and I am thinking about doing it on the Antarctic glaciers/ice shelves. Is there a specific area within this that you would recommend researching into? Thank you! Hi Elli, What exactly does your project

Asked by An interested scientist Periglacial landforms are landforms created by perennially frozen ground that it subject to freeze-thaw processes. You can read more about it on the Periglacial page.

Asked by Dale In October of 2012 a plane from the IceBridge mission made a radar survey of the gateway area of the Thwaites Glacier; can you let me know how to find out the results of this aerial radar survey (either from a NASA website or from a report)? Hi Dale. You can find

Asked by Dale You can find out a lot of information about the GRACE satellite on the GRACE website, but most information using the GRACE data appears in peer-reviewed publications. For example, Chen et al. 2007 discuss the recent change in the Patagonian Ice Sheet, and in the Antarctic Ice Sheet. Skeptical Science also discuss

Asked by Alex A glacier that has periodic episodes of faster and slower flow is called a surge-type glacier. You can learn more about Surge-Type glaciers here.
