A study analysing the climate-change goals of various nations has ranked New Zealand among the worst performers. Along with China and Russia, New Zealand’s climate change polices would propel the world to five degrees of warming by the end of the century, says the study, published in November in the journal Nature Communications. Researchers looked at different countries’ climate-change policies and determined the temperature rise that would ensue if all other nations followed their example. The United States and Australia are ranked slightly better, but their policies would lead to more than four degrees of warming. Recently, the World Meteorological Organization’s 2018 Climate Report found the world was not on track to meet the climate-change targets determined in the Paris Agreement. Similarly, a United Nations report published in November found that emissions of carbon dioxide rose in 2017, the first increase in four years. To meet the Paris goals, emissions must peak by 2020.
