CNBC IPCC Report on Climate World’s t

op climate scientists issue ‘survival guide for humanity,’ call for major course correction- PUBLISHED MON, MAR 20 20239:02 AM EDT UPDATED MON, MAR 20 202310:02 AM EDT-The U.N.’s Intergovernmental Panel on Climate Change said the unprecedented challenge of keeping global warming to 1.5 degrees Celsius above pre-industrial levels had become even greater in recent years due to the relentless increase in global greenhouse gas emissions.

This has resulted in more frequent and more intense extreme weather events that have caused increasingly dangerous impacts on nature and people in every region of the world, the report said.

Deep, rapid and sustained greenhouse gas emission reductions across all sectors will be necessary if warming is to be limited by 1.5 degrees Celsius, the report says, noting that global emissions should already be decreasing and will need to be slashed almost in half by 2030.

The 1.5 degrees Celsius temperature threshold is widely recognized as crucial because so-called tipping points become more likely beyond this level. Tipping points are thresholds at which small changes can lead to dramatic shifts in Earth’s entire life support system.

“Mainstreaming effective and equitable climate action will not only reduce losses and damages for nature and people, it will also provide wider benefits,” IPCC Chair Hoesung Lee said in a statement.

“This Synthesis Report underscores the urgency of taking more ambitious action and shows that, if we act now, we can still secure a liveable sustainable future for all.”

“We have the tools to stave off and reduce the risks of the worst impacts of the climate crisis, but we must take advantage of this moment to act now,” Kerry said.

The report’s findings also highlight the losses and damages the world is already experiencing — and will likely continue to face in the absence of effective climate action.

“Climate justice is crucial because those who have contributed least to climate change are being disproportionately affected,” said Aditi Mukherji, one of the 93 authors of this Synthesis Report.

Daily Beast article on IPCC report and Environmental Justice The window of opportunity to prevent the worst outcomes of climate change is rapidly closing—and humanity needs to act fast.

That’s the grim warning aired by the United Nations’ Intergovernmental Panel on Climate Change (IPCC), which issued its latest report on Monday. The paper found that the impact of climate change is actually increasing more rapidly than previously thought, which led to the authors setting a new target benchmark for emissions to be cut by 60 percent by 2035.

The paper included a new target benchmark for greenhouse gas emissions to be cut by 60 percent by 2035 in order to prevent global temperatures from warming to 1.5 degrees Celsius. The previous goal was 42 percent by 2030.

The authors also set a goal that carbon dioxide emissions specifically need to be reduced by 65 percent by 2035. This would require a rapid and radical rollback of fossil fuels within the world’s energy infrastructure—something that Guterres underscored to the press by calling on world leaders to “massively fast-track climate efforts.”

IPCC Report Summary for Policy Makers A.2 Widespread and rapid changes in the atmosphere, ocean, cryosphere and biosphere have occurred. Human-caused climate change is already affecting many weather and climate extremes in every region across the globe. This has led to widespread adverse impacts and related losses and damages to nature and people (high confidence). Vulnerable communities who have historically contributed the least to current climate change are disproportionately affected (high confidence).

B.2 For any given future warming level, many climate-related risks are higher than assessed in AR5, and projected long-term impacts are up to multiple times higher than currently observed (high confidence). Risks and projected adverse impacts and related losses and damages from climate change escalate with every increment of global warming (very high confidence). Climatic and non-climatic risks will increasingly interact, creating compound and cascading risks that are more complex and difficult to manage (high confidence).

B.3 Some future changes are unavoidable and/or irreversible but can be limited by deep, rapid and sustained global greenhouse gas emissions reduction. The likelihood of abrupt and/or irreversible changes increases with higher global warming levels. Similarly, the probability of low-likelihood outcomes associated with potentially very large adverse impacts increases with higher global warming levels. (high confidence)

B.6 All global modeled pathways that limit warming to 1.5°C (>50%) with no or limited overshoot, and those that limit warming to 2°C (>67%), involve rapid and deep and, in most cases, immediate greenhouse gas emissions reductions in all sectors this decade. Global net zero CO2 emissions are reached for these pathway categories, in the early 2050s and around the early 2070s, respectively. (high confidence)

C.3 Rapid and far-reaching transitions across all sectors and systems are necessary to achieve deep and sustained emissions reductions and secure a liveable and sustainable future for all. These system transitions involve a significant upscaling of a wide portfolio of mitigation and adaptation options. Feasible, effective, and low-cost options for mitigation and adaptation are already available, with differences across systems and regions. (high confidence)

C.5 Prioritising equity, climate justice, social justice, inclusion and just transition processes can enable adaptation and ambitious mitigation actions and climate resilient development. Adaptation outcomes are enhanced by increased support to regions and people with the highest vulnerability to climatic hazards. Integrating climate adaptation into social protection programs improves resilience. Many options are available for reducing emission-intensive consumption, including through behavioural and lifestyle changes, with co-benefits for societal well-being. (high confidence)

C.6 Effective climate action is enabled by political commitment, well-aligned multilevel governance, institutional frameworks, laws, policies and strategies and enhanced access to finance and technology. Clear goals, coordination across multiple policy domains, and inclusive governance processes facilitate effective climate action. Regulatory and economic instruments can support deep emissions reductions and climate resilience if scaled up and applied widely. Climate resilient development benefits from drawing on diverse knowledge. (high confidence)

C.7 Finance, technology and international cooperation are critical enablers for accelerated climate action. If climate goals are to be achieved, both adaptation and mitigation financing would need to increase many-fold. There is sufficient global capital to close the global investment gaps but there are barriers to redirect capital to climate action. Enhancing technology innovation systems is key to accelerate the widespread adoption of technologies and practices. Enhancing international cooperation is possible through multiple channels. (high confidence)

Katherine Haehoe- And finally, the good news: many of the solutions are (a) already available today, and (b) benefit us in so many ways -- addressing health, equity, justice, biodiversity, and even economic concerns while increasing resilience and accelerating the transition to a clean energy future.
