What is the estimated range of human-caused global surface temperature increases from 1850-1900 to 2010-2019 according to AR6?

The correct answer identifies the estimated range of human-caused global surface temperature increases from the historical baseline of 1850-1900 to the more recent period of 2010-2019 as being between 0.8°C and 1.3°C. This range aligns with the findings presented in the Sixth Assessment Report (AR6) by the Intergovernmental Panel on Climate Change (IPCC), which consolidates scientific understanding of climate change and its implications.

This increase is significant because it highlights the impact of anthropogenic activities, including the burning of fossil fuels, deforestation, and other practices that elevate greenhouse gas concentrations in the atmosphere, thereby contributing to overall global warming. The specific range underscores the urgency of addressing climate change and implementing effective mitigation strategies to limit future warming, as the effects of temperature rise influence weather patterns, ecosystems, and overall global climate stability.

The other options reflect incorrect estimations of the temperature increase, either being too low or too high, which may mislead about the severity of climate change impacts as recognized in the up-to-date climate science. Therefore, the selection of the range 0.8°C to 1.3°C accurately reflects current scientific consensus and emphasizes the seriousness of the situation regarding human-induced climate
