Climate Change 2007: Synthesis Report -- Summary for Policymakers
note that many of these charts do NOT show changes relative to pre-industrial, but relative to some version of 20th century average:

how are we going to prevent global average temperatures from rising by 1.5C to 2C relative to preindustrial norms (18th century) when we have ALREADY raised temperatures by 1.5C to 2C?

Panel (b) also shows response to extended scenarios for 2100-2300, showing long-term warming commitment.

This visualisation by the Zurich University of Applied Sciences shows the extent of glaciers at the Ice Age peak 21,000 years ago—when the average global temperature was 9°C, versus the 14.4°C average today, and the 13.7°C pre-Industrial level.

* Population has grown 25%
* GDP per capita has grown 52%
* Energy per unit GDP has improved 20%
* CO₂ per unit energy has remained flat
* CO₂ emissions have grown 50%

- Renewables are still dwarfed by fossil fuels.
- The share of carbon-free electricity has barely budged
- EV sales soared this decade
- But EVs are still a sliver of total auto sales
- We need to radically accelerate clean energy additions

Growth without economic growth. European Environment Agency, Jan. 11, 2021
Economic growth is closely linked to increases in production, consumption and resource use and has detrimental effects on the natural environment and human health. It is unlikely that a long-lasting, absolute decoupling of economic growth from environmental pressures and impacts can be achieved at the global scale; therefore, societies need to rethink what is meant by growth and progress and their meaning for global sustainability.
The Piacenzian stage of the Pliocene (2.6 to 3.6 Ma) is the most recent past interval of sustained global warmth with mean global temperatures markedly higher (by ~2–3 °C) than today. Quantifying CO2 levels during the mid-Piacenzian Warm Period (mPWP) provides a means, therefore, to deepen our understanding of Earth System behaviour in a warm climate state. ... We find that CO2 ranged from 389 ppm to 331ppm...
