The report clearly states that climate has changed due to anthropogenic activities and that it is humans who are warming the planet. According to the report and in the summary for policy makers:

Global surface temperature will continue to increase until at least the mid-century under all emissions scenarios considered. Global warming of 1.5°C and 2°C will be exceeded during the 21st century unless deep reductions in CO2 and other greenhouse gas emissions occur in the coming decades.
