Foreword by Professor Petteri Taalas, Secretary-General of the World Meteorological Organization
It has been 28 years since the World Meteorological Organization issued the first state of the climate report in 1993. The report was initiated due to the concerns raised at that time about projected climate change. While understanding of the climate system and computing power have increased since then, the basic message remains the same, and we now have 28 more years of data that show significant temperature increases over land and sea, as well as other changes, such as sea-level rise, melting of sea ice and glaciers and changes in precipitation patterns.
This underscores the robustness of climate science based on the physical laws governing the behaviour of the climate system. All key climate indicators and impact information provided in this report show relentless, continuing climate change, an increasing occurrence and intensification of high-impact events and severe losses and damages affecting people, societies and economies.
Concentrations of the major greenhouse gases continued to increase in 2019 and 2020. Globally averaged mole fractions of carbon dioxide (CO2) have already exceeded 410 parts per million (ppm), and if the CO2 concentration follows the same pattern as in previous years, it could reach or exceed 414 ppm in 2021.
Stabilizing global mean temperature at 1.5 °C to 2 °C above pre-industrial levels by the end of this century will require an ambitious reduction of greenhouse gas emissions, which must begin to occur during this decade.
I take this opportunity to congratulate the experts and the lead author, who compiled this report using physical data analyses and impact assessments. I thank all the contributors, particularly WMO Member National Meteorological and Hydrological Services and Regional Climate Centres and our sister United Nations Agencies for their collaboration and input on this report. The report is intended to help our organizations to update world leaders and citizens on the latest information about our Earth system’s behaviour and climate change impacts. WMO remains committed to supporting this publication and communicating it widely for this purpose.
