19. Climate Emergency https://climateemergencydeclaration.org/ @jawache
20. https://www.theguardian.com/environment/2019/may/17/why-the-guardian-is-changing-the-language-it-uses-about-the-environment The Guardian has updated its style guide to introduce terms that more accurately describe the environmental crises facing the world. Instead of “climate change” the preferred terms are “climate emergency, crisis or breakdown” and “global heating” is favoured over “global warming”, although the original terms are not banned. “We want to ensure that we are being scientifically precise, while also communicating clearly with readers on this very important issue,” said the editor-in-chief, Katharine Viner. “The phrase ‘climate change’, for example, sounds rather passive and gentle when what scientists are talking about is a catastrophe for humanity.” @jawache
21. https://www.motherjones.com/environment/2013/08/raytheon-climate-change-security/ “expanded business opportunities are likely to arise as consumer behaviour and needs change in response to climate change.” ... the company also expects to see “demand for its military products and services as security concerns may arise as results of droughts, floods, and storm events occur as a result of climate change.”
