Climate Change 2021: The Physical Science Basis is the first part of the Sixth Assessment by the Intergovernmental Panel on Climate Change. It confirms that the planet is warming at accelerating and unprecedented rates. This process is expected to keep going until mid-century at the very least. Due to the emitted emissions, global warming will almost certainly go past 1.5 or 2 centigrade within the century.
Aside from that, the report laid out expected effects from extreme weather to water level changes. Many of these changes will be irreversible for a long time. Even back in 1990, the first report already warned of a dark future unless we reduce emissions rapidly. The effects are now felt all over the globe.
The report has said that we should not give up. If mankind wants to avert the worst, we should move away from fossil fuel, use nature-based solutions and “negative emission technologies,” and protect natural carbon sinks. It is also important to be vigilant of entities that downplay the issue. We should move away from individual carbon footprint reduction and demand for systemic change from our governments, media, and businesses.
