What's wispy and feathery and made of ice? You got it - it's a cirrus cloud. Cirrus are pretty cool - you can use them to forecast the weather, and despite their flimsy appearances, they actually have a pretty important effect on global climate. ********** If you liked this video and want to support me, please consider becoming a patron on Patreon: https://www.patreon.com/Dr_Gilbz

What is going to happen to Antarctic ice shelves in the near future? How will ice shelves around the continent respond to temperature rise, increased atmospheric humidity and other climatic changes? In a new paper, published in Geophysical Research Letters, we show that melt and runoff increase with warming, meaning that ice shelves are at greater risk of hydrofracturing-induced collapse. Those particularly vulnerable include the Larsen C, Wilkins, Pine Island and Shackleton ice shelves.

I'm a climate scientist, and also a woman, which apparently means I'm fair game to receive unsolicited quackery from climate deniers and Men On The Internet (who sometimes even happen to be the same people!). Sharing is caring, so I asked some of my colleagues to contribute the most hilarious and outrageous correspondence that they had received. Funnily enough, there's a few people who crop up a lot - seems like they have nothing better to do than harass scientists online. So, here I am, reading some of the highlights for your delight and titillation. You're welcome.

What on Earth is the IPO? TL;DR • The IPO is a multi-decadal pressure pattern that influences weather • It varies over long timescales • It may have played a role in the so-called global warming “hiatus” The IPO is a complex climate pattern that involves interactions between the atmosphere and ocean, similar to ENSO, but less well understood. It's also related to the Pacific Decadal Oscillation, which occurs over a different part of the Pacific Ocean. But how is it related to climate change? Can it explain the global 'pause' in warming? Is it even a thing??? ... watch on to find out. ============================================================= If you like these videos and would like to help me make more of them, please consider supporting me on Patreon: https://www.patreon.com/Dr_Gilbz​ ============================================================= References and further reading Henley et al.

The EU's Copernicus Climate Service has announced that 2020 was the joint hottest year since measurements began - it shares the record with 2016. That heat brought record levels of flooding, heatwaves and storms to many parts of the world, with far-reaching consequences. If the pandemic has taught us anything, it's that we can achieve a lot when we tackle something as a priority - it's time to treat climate change as an emergency and take climate action now. ============================================================= If you like these videos and would like to help me make more of them, please consider supporting me on Patreon: https://www.patreon.com/Dr_Gilbz ============================================================= Resources & further reading * https://www.carbonbrief.org/analysis-coronavirus-set-to-cause-largest-ever-annual-fall-in-co2-emissions * https://public.wmo.int/en/media/press-release/2020-track-be-one-of-three-warmest-years-record * https://www.nature.com/articles/d41586-020-02568-y * https://earthobservatory.nasa.gov/images/event/146855/2020-fire-season-in-the-western-us * https://appliedsciences.nasa.gov/what-we-do/disasters/disasters-activations/central-and-east-africa-floods-2020 * https://earthobservatory.nasa.gov/images/147006/excessive-monsoon-rains-flood-asia * https://reliefweb.int/sites/reliefweb.int/files/resources/20201120_CA%20Eta%20SitRep%204%20ENG.pdf

A mega iceberg - known to its friends as A68 - has been drifting in the Southern Ocean since its break-away from the Larsen C ice shelf on the Antarctic Peninsula in 2017. The berg, plus the smaller parts it has broken up into, have been making a beeline for the island of South Georgia, where scientists were concerned it could cause trouble for local wildlife. In one of the few good news stories of 2020, it has now moved off-course and broken up into smaller bits. ********* Track the course of the iceberg using ESA's satellite data browser here: https://earth.esa.int/eogateway/ You can also track its course on Twitter using the hashtag #A68a Some interesting articles on A68a & pals: https://www.bbc.co.uk/news/science-environment-55413969 https://www.bbc.co.uk/news/science-environment-55428520 https://www.theguardian.com/world/2020/dec/29/fractures-to-antarctic-iceberg-reduce-risk-to-south-georgia-wildlife ********** If you liked this video and want to support me, please consider becoming a patron on Patreon: https://www.patreon.com/Dr_Gilbz

Flat, grey and drizzly - must be a stratus cloud. These layer clouds prevent sunlight reaching the surface and trap outgoing heat from the Earth, warming the surface at night and cooling it in the day. Climate change will have an influence on stratus, and this in turn will affect our climate - just one of many complex climate feedbacks. ********** If you liked this video and want to support me, please consider becoming a patron on Patreon: https://www.patreon.com/Dr_Gilbz
