While the on-the-ground, UN Climate Change Conference in Santiago, Chile, has been c̶a̶n̶c̶e̶l̶e̶d̶ moved to Madrid, Spain due to anti-government protests, our online social virtual reality UN Climate Change event proceeds as planned! Join us during our (unofficial, but authoritative and phenomenal) Climate Change Conference to discuss & debate & decide... in the Climate Cafe & Sustainability Studio, floating above Santiago via the wonders of 360 photography!
Background: The average global temperature for 2015–2019 is on track to be the warmest of any equivalent period on record. It is currently estimated to be 1.1 ° Celsius (±0.1°C) above pre-industrial (1850–1900) times. Widespread and long-lasting heatwaves, record-breaking fires and other devastating events such as tropical cyclones, floods, and drought have had major impacts on socio-economic development and the environment. Arctic summer sea-ice extent declined 12% per decade during 1979-2018. Levels of the main long-lived greenhouse gases, carbon dioxide (C2 ), methane (CH4) and nitrous oxide (N2O) have reached new highs. The last time Earth's atmosphere contained 400 parts per million CO2 was about 3-5 million years ago, when global mean surface temperatures were 2-3°C warmer than today, ice sheets in Greenland and West Antarctica melted, parts of East Antarctica ice had retreated, all causing the global sea-level rise of 10-20m compared with today. CO2 concentrations are on track to reach or even exceed 410 parts per million (ppm) by the end of 2019. Natural CO2 sinks, such as vegetation and oceans, which remove about half of all emissions from human activities, but will become less efficient. This underscores the need to reduce deforestation and expand natural CO2 sinks, particularly those in forests and soils that can be improved by better management and habitat restoration: scaling up and replicating existing, well-proven policies - such as switching to renewable energy and reforestation - that simultaneously contribute to key sustainable development goals. Consolidated evidence reinforces human influence as the dominant cause of changes to the Earth system, in a new geological epoch, the Anthropocene. Growing climate impacts increase the risks of crossing critical tipping points. These refer to thresholds that, if crossed, lead to far-reaching, in some cases abrupt and /or irreversible changes. There is a growing recognition that climate impacts are hitting harder and sooner than climate assessments indicated even a decade ago. As climate change intensifies, cities are particularly vulnerable to impacts such as heat stress and can play a key role in reducing emissions locally and globally. Only immediate and all-inclusive action encompassing: deep de-carbonization complemented by ambitious policy measures, protection and enhancement of carbon sinks and biodiversity, and efforts to remove CO2 from the atmosphere can slow and reduce potentially devastating consequences.

(Canceled, due to anti-government protests.) The 2019 United Nations Climate Change Conference, also known as COP25, will be the 25th United Nations Climate Change Conference. It will be held in Santiago, Chile, between 2–13 December 2019.
