Abstract

The potential for societal collapse has become a pressing concern as the impacts of climate change intensify, threatening global stability. This paper explores the multifaceted risks of collapse, emphasizing the interconnected environmental, economic, and geopolitical pressures that contribute to vulnerability. By examining historical collapses, such as those of the Roman Empire and the Maya civilization, alongside contemporary examples like Syria, Venezuela, and Yemen, the paper highlights the unique challenges of the current global crisis. Unlike past localized collapses, today's climate crisis is unprecedented in its speed and scale, raising critical questions about the adaptability of modern societies. The study proposes adaptive strategies, including fostering local self-sufficiency, building resilient community networks, and embracing uncertainty as central to survival in a deeply altered world. It argues that while historical lessons provide valuable insights, new approaches are needed to navigate the complexities of the Anthropocene. Ultimately, the paper underscores the urgency of reimagining societal resilience to confront an era defined by profound environmental upheaval and uncertainty.

Sci-Net will ask for a minimum amount of 1000 Sci-Hub tokens to register. The tokens will appear on your account after registration and will be used to reward uploaders. That is the most controversial part: some people argue that Sci-Net introduces paywall similar to publisher.

Even though both might appear similar at a first glance, the differences are profound. Compared to insane publisher paywalls, the entry tax on Sci-Net is symbolic and is not higher than an equivalent of a cup of coffee in most countries. The next difference is that in traditional approach, profits are made by publisher, and ordinary researcher has no control on how the money are used. On Sci-Net, you're using tokens directly to reward uploaders. Payments go to fellow researchers, not to the platform.

But the most important is that publishers will charge for access to the same paper again and again. Sci-Net will only do that once when paper is uploaded and after that, it will remain free forever and for everyone -- even users who are not registered on the platform will be able to access it. That is, all Sci-Net transactions contribute directly to public domain, and the number of knowledge accessible to everyone grows with Sci-Net usage.

The more people use Sci-Hub token, the more valuable it becomes. That way Sci-Net indirectly contributes to maintenance and further development of Sci-Hub.

The only downside is that obtaining Sci-Hub tokens on the Solana network can be a non-trivial puzzle for a user who are new to crypto. But that only makes the process more interesting.

Chinese President Xi Jinping has agreed to finance the construction of Kenyan roads and railways including the rebuilding of a notorious accident black spot.

Xi made the pledge when he welcomed his Kenyan counterpart William Ruto to Beijing on Thursday, promising also to support “high-level connectivity, and sustainable trade”.

The funding he pledged will include work to rebuild the Nithi Bridge in central Kenya, a notorious death trap that has claimed hundreds of lives since its commissioning four decades ago. The plan involves the building of a viaduct that will remove the steep descents and sharp corners that make the bridge so dangerous.

Kenya is a key partner for China’s Belt and Road Initiative – a transcontinental infrastructure project – that has already helped build a rail link between Mombasa, Nairobi and the Central Rift Valley at a cost of around US$5 billion.

Apart from railway projects, China also agreed to allow Kenya to explore the issuing of yuan-denominated panda bonds while Xi pledged to continue talks about a free-trade agreement and to “import more fine Kenyan products and promote the balanced and sustainable development of bilateral trade”.

Abstract

Climate-driven forest mortality events have been extensively observed in recent decades, prompting the question of how quickly these affected forests can recover their functionality following such events. Here we assessed forest recovery in vegetation greenness (normalized difference vegetation index) and canopy water content (normalized difference infrared index) for 1,699 well-documented forest mortality events across 1,600 sites worldwide. By analysing 158,427 Landsat surface reflectance images sampled from these sites, we provided a global assessment on the time required for impacted forests to return to their pre-mortality state (recovery time). Our findings reveal a consistent decline in global forest recovery rate over the past decades indicated by both greenness and canopy water content. This decline is particularly noticeable since the 1990s. Further analysis on underlying mechanisms suggests that this reduction in global forest recovery rates is primarily associated with rising temperatures and increased water scarcity, while the escalation in the severity of forest mortality contributes only partially to this reduction. Moreover, our global-scale analysis reveals that the recovery of forest canopy water content lags significantly behind that of vegetation greenness, implying that vegetation indices based solely on greenness can overestimate post-mortality recovery rates globally. Our findings underscore the increasing vulnerability of forest ecosystems to future warming and water insufficiency, accentuating the need to prioritize forest conservation and restoration as an integral component of efforts to mitigate climate change impacts.

The US has been bombing Yemen using two aircraft carriers in the region and B-2 bombers stationed at Diego Garcia in the Indian Ocean. The Pentagon has shared virtually no details about its war, which has not been authorized by Congress, but it's likely the bombing campaign has already cost billions in just over one month.
