Report Heartland Institute sent to influence US teachers on climate change earns an “F” from scientists

The warming experienced since the Industrial Revolution could not have been caused by natural factors. Human activity is primarily responsible for this (ongoing) change in climate.
Global temperatures have continued to rise over the last few decades—notably in the oceans, which store over 90% of the excess heat trapped by the greenhouse gases humans have emitted. Over short intervals, temperatures may appear to increase slower or faster than the long term trend.
Climate models are based on physical processes and our understanding of how the climate system works. Their sensitivity to CO2 is in line with estimates based on modern observations and records of past climate changes.
The rapid loss of glacial ice and Arctic sea ice cover is a clear sign of the large human impact on the climate system.
Globally, sea level is rising due to melting glacial ice and warming oceans, and the current rate of sea level rise is faster than past rates.
The warming influence of CO2 has been much greater than that of the Sun over the past century, and the pattern of observed climate change cannot be explained by solar forcing.
“Neglecting feedbacks in this statement is seriously misleading to uninformed readers. Feedbacks have been clearly identified as major amplifiers of the initial CO2-forced change. These feedbacks are explicitly resolved in climate models.”

Roughly 900 million people lived in low-lying coastal cities and settlements in 2020; a figure that is projected to reach 1 billion by 2050. Is there anything we can do now to reduce sea-level rise and its impacts? Our past actions will already impact sea-levels for thousands of years. But not everything is set in stone. We possess the power to reduce sea-level rise and its impacts over the next century and beyond with our current actions. Some advocate to mitigate the causes, and others to adapt to the consequences. But what do experts say?
