  • Summary

    Global greenhouse gas emissions linked to human activities continue to increase, and as a result global temperatures keep rising and the impact of climate change is increasingly felt by all communities. This chapter reviews the observed evidence of climate change and analyses greenhouse gas emissions in different countries and/or groups of countries to understand how we reached current concentrations and warming levels. The contribution also discusses the key conclusions of the Summary Report for Policy Makers published by Working Group I of the Intergovernmental Panel on Climate Change in August 2021, and applies a quasi-linear relationship between cumulated greenhouse gases and global warming to illustrate how emission reductions could limit global warming
