The report explains how governments will need to take new measures to deal with extreme impacts and prepare for losses due to climate change. Unless substantial efforts are taken immediately to reduce greenhouse gas emissions and encourage climate resilient development, global warming could exceed 4 and even 6°C. The costs will place a massive burden even on industrialized countries, whilst massively increasing poverty and reversing development gains in poorer regions. The figures are staggering, conservative estimates show that we could risk around 2 trillion USD in economic and non-economic impacts worldwide by the year 2060 combined with potentially irreversible losses to ecosystems and biodiversity.
