It's true as you say that diseases can spread more when climate changes. There is also the threat from increasing ice, just reported two days ago. Average global temperatures are now at a standstill for 17 years, notincreasing notwithstanding the rapid accumulation of CO2 emissions. The models are being adapted so CO2 lags temperature as it did historically. That probably explains the record growth of ice. http://www.dailymail.co.uk/news/article-2681829/Global-warming-latest-Amount-Antarctic-sea-ice-hits-new-record-high.html
is the health system prepared for coninuing trend like this? This wll have high adapting costs and health costs. Ice reduces availlable drinking water directly and also reduces food availability because oj lower yields. Fall in nutrition wll lead to worse population health, as the author pointsout. Specifying the timeframes for these profound changes is important. I hope the World Bank can shed light on the timeframes so health system investments are made accordingly and especially with a view toward Universal Health Coverage by goal for 2050.
