Chart shows affordable ways to avoid climate catastrophe.......Cutting greenhouse gas emissions to keep the worslash them by more than half over the next seven years are readily available and cost-effective — and necessary to keep the global average temperature from rising more than 1.5 C. The recent Intergovernmental Panel on Climate Change Sixth Assessment Report includes a chart that shows how. ld from heating to catastrophic levels is entirely possible and would save money. Although emissions continue to rise, there’s still time to reverse course. Ways to Compiled by the world’s top scientists using the most up-to-date research, it illustrates potential emissions reductions and costs of various methods. At the top are wind and solar power, followed by energy efficiency, stopping deforestation and reducing methane emissions. Nuclear energy, carbon capture and storage and biofuels bring much poorer results for a lot more money. Wind and solar together can cut eight billion tonnes of emissions annually — “equivalent to the combined emissions of the US and European Union today” and “at lower cost than just continuing with today’s electricity systems,” the Guardian reports. Nuclear power and carbon capture and storage each deliver only 10 per cent of the results of wind and solar at far higher costs. It’s telling that those less effective, more expensive pathways are the ones touted most often by government, industry and media people who are determined to keep fossil fuels burning or are resistant to power sources that offer greater energy independence. Making buildings, industry, lighting and appliances more energy efficient could cut 4.5 billion tonnes of emissions a year by 2030 — and there’s no doubt that simply reducing energy consumption could add to that.         https://davidsuzuki.org/story/chart-shows-affordable-ways-to-avoid-climate-catastrophe/?utm_source=mkto-none-smSubscribers-readOnline-body&utm_medium=email&utm_campaign=scienceMatters-chartShowsAffordable-en-05may2023&mkt_tok=MTg4LVZEVS0zNjAAAAGLkZthONY8mOOeoVGDuKX0KxF4AQiZVVS2x3I_YE532LiRfRa-t7oXDx4KEuL-CNrnSreBZZyeD4XGoGsmvun0uhnLS8PrbNf4rOLCOJoqM8SY
