Climate crisis, the sixth IPCC report is very negative

The Sixth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC), said the progression of the climate crisis is indeed negative. The IPCC report explains: "Human activities, mainly through greenhouse gas emissions, have unequivocally caused global warming, with global surface temperatures reaching 1.1°C above 1850-1900 in 2011-2020.

There have been widespread and rapid changes in the atmosphere, ocean, cryosphere and biosphere Human-caused climate change is already influencing many extreme weather and climate events in every region of the world. This has led to widespread adverse impacts and related losses and damage to nature and people Vulnerable communities that have historically contributed least to current climate change are disproportionately affected Global GHG emissions in 2030 implied by nationally determined contributions (NDCs) announced by states by October 2021 “make it likely that warming will exceed 1.5°C during the 21st century and will make it more difficult to limit the warming below 2°C.

There are gaps between emissions projected by implemented policies and those projected by NDCs, while financial flows fall short of the levels needed to meet climate targets across all sectors and regions. Limits have been reached in some ecosystems and regions: Current global financial flows for adaptation are insufficient and limit the implementation of options, especially in developing countries.


Continued greenhouse gas emissions will lead to 1.5°C in the near term under the considered scenarios and modeled pathways, and any increase in global warming will intensify multiple and concomitant risks. Deep, rapid and sustained reductions in greenhouse gas emissions would lead to a marked slowdown in global warming within about two decades and also to noticeable changes in atmospheric composition within a few years.

Many climate-related risks are higher than those assessed in AR5, and projected long-term impacts are up to many times higher than currently observed. Climate and non-climate risks will increasingly interact, creating more complex and difficult to manage compound and cascading effects.

Some future changes are inevitable and/or irreversible, but may be limited by a deep, rapid and sustained global reduction in greenhouse gas emissions."
