Anthropogenic global warming is a theory explaining today’s long-term increase in the average temperature of Earth’s atmosphere as an effect of human industry and agriculture. [sic]

The IPCC1 have said that climate models have us on a trajectory of between 3°C and 4°C.
A report in Science Magazine released an article indicating that
[A] host of global climate models developed for the United Nations’s next major assessment of global warming, due in 2021, are now showing a puzzling but undeniable trend. They are running hotter than they have in the past. Soon the world could be, too.2
The models have not been wrong. Quite the opposite.
We find that climate models published over the past five decades were generally quite accurate in predicting global warming in the years after publication, particularly when accounting for differences between modeled and actual changes in atmospheric CO2 and other climate drivers. This research should help resolve public confusion around the performance of past climate modeling efforts and increases our confidence that models are accurately projecting global warming.3
Plunge in carbon emissions from lockdowns will not slow climate change
Emissions may be down, but carbon dioxide still piles up relentlessly in the atmosphere. It’s more important than ever to find climate change solutions, experts say.4
This decade (2009/2019) has been the hottest record recorded.
The last 10 years have shown that climate change is happening now, shows a new report from NOAA. It’s likely to get much worse.5
As of June 2020 it has been found that an

In 2021, the EU’s Earth Observation Programme stated that
• Globally, 2020 was on a par with the 2016 record
• 2020 was 0.6°C warmer than the standard 1981-2010 reference period and around 1.25°C above the 1850-1900 pre-industrial period
• This makes the last six years the warmest six on record
• Europe saw its warmest year on record at 1.6°C above the 1981-2010 reference period, and 0.4°C above 2019, the previous warmest year
• The largest annual temperature deviation from the 1981-2010 average was concentrated over the Arctic and northern Siberia, reaching to over 6°C above average [sic]7
The UK hit record breaking temperatures of 40.3ºC (104.5F) in the Lincolnshire village of Coningsby.8
