"Back in 1990, with 110 years of temperature records behind them, the world’s
top climate scientists convened to put together a report on the state of the
Earth’s climate. Working collaboratively, the fruits of their labor became the
very first Intergovernmental Panel on Climate Change (IPCC) report. It
definitively showed:
* there had been a global increase in carbon dioxide concentrations since
pre-industrial times from ~280 parts-per-million (ppm) to 354 ppm,
* this was coupled with a global average temperature increase of 0.7 °C (1.3
°F),
* that the increase in temperature was being driven not by the Sun, volcanoes,
or urbanization, but rather by the human-wrought changes to our atmospheric
contents,
* and that this problem would continue to worsen unless carbon dioxide
emissions were curbed.
Despite sounding the alarm, the past three decades have led to a far more dire
situation. As identified in 2021’s 6th IPCC report, carbon dioxide
concentrations now sit at 412 ppm, Earth’s average temperature is a full 1.3 °C
(2.3 °F) above pre-industrial levels, and our global carbon emissions have
increased to a new all-time high: nearing 40 billion tonnes of carbon dioxide
annually, up from 22 billion in 1990. The best time to act was long ago, but
the second best time to act is now. Here are the truths of the matter that
everyone who’s vested in following what the science shows should know."
