@chopperoon1 While it's tempting to view a 1.2-degree increase over 100 years as 'minuscule,' it's crucial to understand the broader context. This seemingly small temperature rise has already led to significant changes in climate patterns, including more frequent and severe weather events.
As for the 400 ppm of CO2, it's not just the absolute number that matters, but the rate at which it's increasing. The global average atmospheric CO2 was 417.06 ppm in 2022, setting a new record high. This marks the 11th consecutive year where the amount of CO2 in the atmosphere has increased by more than 2 ppm. The annual rate of increase in atmospheric CO2 over the past 60 years is about 100 times faster than previous natural increases, such as those that occurred at the end of the last ice age 11,000-17,000 years ago.
Moreover, CO2 is Earth's most important greenhouse gas. In 2021, CO2 alone was responsible for about two-thirds of the total heating influence of all human-produced greenhouse gases. Even a 'low' concentration of 400 ppm has significant implications for global warming and ocean acidification.
So, while the numbers may seem small in isolation, their impact on our planet is anything but. It's not just about what will happen naturally; it's about how human activities are accelerating these changes at an unprecedented rate.
I'd recommend doing your own research to understand the gravity of these numbers, rather than relying solely on someone else's interpretation of these studies.
