This is where the FACTS (real ones) and their checking (via peer review and the scientific method) matter. The planet IS getting warmer disastrously fast.
"All five datasets surveyed by WMO concur that 2011-2020 was the warmest decade on record, in a persistent long-term climate change trend. The warmest six years have all been since 2015, with 2016, 2019 and 2020 being the top three." -- From a World Meteorological Organization report.
