4) It is now out of date. The science has moved on since our targets were set in 2018, with the impacts of global heating looking ever more serious. This calls for more rapid action.
As we learn more about climate change, the prognosis is worsening. Here are just a few examples:
- Warming is closer to 1.5°C than thought in 2018 - Met Office Dec 2020
- Plants’ ability to absorb human-caused CO2 may halve within 20 years due to heating and drying, leading to a tipping point expected to accelerate warming - Northern Arizona University Jan 2021
- The Gulf Stream ocean current is weakening, threatening more extreme weather in Europe and the US. Circulation has already slowed by a huge 15%, and is heading ultimately for a dangerous tipping point – Potsdam Feb 2021
- It turns out that industrial fishing’s method of dragging heavy bars across the ocean floor releases more CO2 than air travel – Time Mar 2021
- A warning that chemicals & microplastics in waste water from sewage works, combined with ocean acidification from increased CO2 levels, could threaten a marine ecosystem collapse in just 20 years, with up to 90% of marine life at risk - GOES Foundation Jun 2021
