United in Science Report

The United in Science Report has been created by the world’s leading climate science organizations who have joined forces to produce a unified assessment in preparation for the United Nations Climate Action Summit.

The report underlines the glaring and growing gaps between agreed on targets to tackle global warming and the actual reality, highlighting the urgency for the development and implementation of concrete commitments and actions. The current state of the planet, humanity’s response to date and the changes that are projected have been summarised in this landmark report.

The UN Environment Programme contributed two pages from its flagship report, The Emissions Gap Report, whose tenth edition is, released on 25 November. It assesses the latest scientific studies on current and estimated future greenhouse gas emissions, highlighting the gap of “where we are likely to be and where we need to be” and summarizes what is needed to get there.

Sea-level rise is accelerating, sea water is becoming more acidic. The observed rate of global mean sea- level rise increased from 3.04 millimeters per year (mm/yr) during the period 1997– 2006 to approximately 4 mm/yr during the period 2007–2016. The accelerated rate in sea level rise as shown by altimeter satellites is attributed to the increased rate of ocean warming and land ice melt from the Greenland and West Antarctica ice sheets.
