The lead stated:
The IPCC Sixth Assessment Report looked at impact of climate change on water security and found in 2022: "Increasing weather and climate extreme events have exposed millions of people to acute food insecurity and reduced water security [...]." The report says the regions which are impacted the most so far include Africa, Asia, Central and South America, Small Island Developing States and the Arctic.
I've decided to cut this directly as the IPCC summary puts food insecurity and water security in one sentence, so it's unclear what parts of the summary refer to what. Instead I've used the FAQ in Chapter 4 to talk more about this. FAQs in the IPCC reports are probably our best source: easy to summarise (SPM is already summarised, making paraphrasing difficult), written for a more lay audience.
Need to bow out now, and have not integrated the text in the body (which requires some work and wanted to make sure you're happy first). Very happy with a stronger statement too, as long as it's specific about water security and paraphrased. —Femke 🐦 (talk) 16:41, 18 February 2023 (UTC)
- Thanks, that's good. Good idea about relying more on the FAQ sections than on the technical or policy maker summaries. I would like to keep something in the main text (under "global estimates") regarding how many people are affected, i.e. that statement of "millions of people". It's vague, I know, but so is the whole concept of water security to some extent (hard to measure in absolute terms).
- The IPCC statements that I had picked out so far say millions of people in the one sentence but billions of people when referring to water scarcity and water stress....:
"Increasing weather and climate extreme events have exposed millions of people to acute food insecurity and reduced water security, with the largest impacts observed in many locations and/or communities in Africa, Asia, Central and South America, Small Islands and the Arctic".[1]: 9 The same report predicted that "at approximately 2°C global warming level, between 0.9 and 3.9 billion people are projected to be at increased exposure to water stress, depending on regional patterns of climate change and the socio-economic scenarios considered."[2]: 558 With regards to water scarcity (which is one parameter that contributes to water insecurity), the report states that "between 1.5 and 2.5 billion people live within areas exposed to water scarcity globally".[1]: 660
