06/12/2019 – The pace of contemporary rise in greenhouse gas concentrations is unprecedented in climate history over the past 66 million years and weather extremes are the “new normal,” according to some of the latest findings in climate science compiled in an easy-to-read guide for negotiators, policymakers, and media for the COP25 world climate summit. PIK Director Johan Rockström and colleagues from Future Earth and the Earth League today presented the “10 New Insights in Climate Science” report to UNFCCC’s Executive Secretary Patricia Espinosa at the meeting in the Spanish capital Madrid.

19.12.2018 - The reality of ongoing climate warming might seem plainly obvious today, after the four warmest years on record and a summer of weather extremes in the whole northern hemisphere. A few years back however, some media and some experts were entangled in debates about an alleged pause in global warming – even though there never has been statistical evidence of any “hiatus”, as new research now confirms. In two recent studies, a group of international scientists joined forces to thoroughly disentangle any possible “hiatus” confusion, affirming that there was no evidence for a significant pause or even slowdown of global warming in the first place.

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.
