Mix it: Policy combination needed to achieve climate targets along with sustainable development goals
06/20/2018 - A broad combination of policies might be best suited to help achieve both climate stabilization targets as well as most of the UN Sustainable Development Goals. These policies reach from straightforward CO2 pricing to regulation of water and forest protection, to lifestyle changes such as eating less meat, a new study shows. The scientists highlight the complex interplay between the different targets. A policy focused only on CO2 pricing would cost the least, they show, but would likely trigger substantial land-use changes.

Wealth inequality: closing the gap by taxing land and bequests
22/03/2018 - To reduce wealth inequality without diminishing the economic performance of a country, a policy package of bequest taxes and land value taxes could be the optimal solution. Such a policy package would, in fact, have a strong advantage over corporate taxation, a new study published in the journal International Tax and Public Finance finds. It is the first analysis to include the so far neglected factor of land for tackling wealth inequality. Land is of great interest for studying inequality as climate change might increase land prices and thereby affect housing costs. The cost increase could be countered by smart taxes that would at the same time reduce overall inequality in a country, and hence possibly help to reduce tensions in society that are amplified by populism.

Early Summer Monsoon forecast for India
05/07/2018 - the Indian Summer Monsoon will likely reach Central India between 11 and 19 June, according to the new forecast method developed at the Potsdam Institute for Climate Impact Research (PIK). The unique forecast had been developed specially for the central part of India where, before, early forecasting has never been made. The novel approach based on an analysis of observational data allows predicting the monsoon onset date 40 days in advance. Elena Surovyatkina leads the forecasts that showed to be successful already two years in a row. The monsoon onset date is of crucial importance for hundreds of millions of people in India. Climate change affects monsoon variability and hence makes accurate forecasting even more important.

Worldbank report with PIK: climate change can trigger migration of millions
19/03/2018 - Climate change is a driver of future migration – in a worst-case scenario, it could force more than 100 million people out of their homes by 2050. This is shown by a groundbreaking Worldbank report, co-authored by scientists from the Potsdam Institute for Climate Impact Research (PIK). Subsaharan Africa and Southern Asia are among the most affected regions, to a lesser extent also Latin America. Water scarcity and yield failures are, along with a number of other economical and social factors, becoming more and more relevant for migration within countries. This so-called internal migration is the subject of the report. However, rapid reductions of greenhouse-gas emissions can reduce this future migration by up to 80 percent, according to the report.
