Forests that once felt permanent are now failing in real time, with officials warning that some ecosystems are edging toward total collapse. From the Mediterranean to the tropics, prolonged drought, fire, and flooding are converging into what Jan officials have called an “Unprecedented” crisis for trees and the communities that depend on them. I see the same pattern repeating across continents: a slow-motion breakdown that scientists have warned about for decades, now arriving faster than politics or policy.
The stakes are not abstract. Forests regulate water, stabilize soils, and store vast quantities of carbon, yet they are being pushed past thresholds they were never evolved to withstand. As the climate warms beyond the once symbolic line of 1.5°C, the world’s remaining woodlands are shifting from buffers against disaster to victims of it, and in some cases new sources of risk.
Southern Israel’s forests as an early warning system
In southern Israel, the alarm is no longer theoretical. Jan Officials have warned that a worsening crisis is pushing local forests to the brink of collapse, describing the situation as “Unprecedented” as trees die back across the Yatir, Dudaim, and Gerar forests. These woodlands were planted as green belts in a semi-arid landscape, but years of heat and water stress are now exposing how fragile that experiment has become, with foresters reporting widespread canopy thinning and mortality.
The problem is not limited to a single grove or hillside. Across Southern Israel, prolonged droughts and declining groundwater are undermining the very conditions that allowed these forests to take root. Jan Officials have linked the die-off to a combination of rising temperatures, shifting rainfall, and soil degradation, warning that without rapid adaptation, the Yatir, Dudaim, and Gerar forests could unravel into patchy scrub and bare ground. When I look at those warnings, I see less a local anomaly than a preview of what many dryland forests will face as the climate continues to heat.
Climate thresholds and the path to systemic collapse
The crisis in Israel sits within a much larger climate picture that is turning from prediction to lived reality. For the first time, global temperature has permanently surpassed the mark of 1.5°C, a threshold that scientists long treated as a warning line for dangerous climate disruption. According to analysis prepared around COP 30, For the world’s forests this is not a distant scenario but a present-tense stress test, with hotter, drier conditions eroding resilience that took centuries to build.
As the COP 30 climate summit in BM entered its final week, environmental groups warned that government promises were falling short in halting deforestation in key rainforests, even as the temperature signal grew clearer. Their concern was that without stronger action, the combination of heat, land clearing, and industrial pressure could push vast forest regions toward tipping points where collapse becomes self-reinforcing. I read those warnings as a direct echo of what Jan Officials are already seeing on the ground in Israel, and as a sign that the global climate regime is still lagging behind the pace of ecological change.
Wildfire, water, and the “gray rhino” of forest risk
Fire is one of the clearest ways this new climate reality is expressing itself. Wildfires now destroy twice as much tree cover per year as they did two decades ago, a surge that researchers link directly to hotter, drier conditions and more frequent extremes. Mapping work has shown how Wildfires are eating into boreal and temperate forests that once acted as stable carbon sinks, with scientists such as Ashley Kirk and colleagues highlighting how repeated burns can convert dense woodland into open shrubland or grass.
At the same time, the forest crisis is not only about flames. Hydrologists and ecologists have been warning that the breakdown of forest cover is also a water crisis, a point captured in the description of the “gray rhino” risk facing global forest-water systems. One analysis describes this as a highly probable, high-impact crisis that we can see charging from a distance, with the Center for International Forestry Research and World Agroforestry, or CIFOR-ICRAF, among those sounding the alarm. The argument is that by ignoring this forest-water “gray rhino,” governments are setting themselves up for cascading failures in rivers, agriculture, and urban water supplies as tree cover thins.
Sumatra’s floods and the cost of weakened protection
If drought and fire define one edge of the crisis, catastrophic flooding marks another. Sumatra, Indonesia’s second-largest island and one of the world’s richest biodiversity hotspots, has been hit by severe floods that have displaced communities and swamped farmland. Indonesia’s government has filed multiple lawsuits over the disaster, arguing that weakened ecological safeguards and land-use decisions amplified the damage. In official statements, authorities have linked the inundation to the long-term erosion of forest buffers that once absorbed heavy rains across Sumatra.
Visuals shared from the disaster zone show entire valleys turned into brown lakes, with roads and villages cut off for days. One widely circulated update described how Indonesia is now confronting the consequences of weakened ecological protection, as deforested slopes shed water faster and rivers burst their banks more violently. When I compare this to the slow desiccation in southern Israel, the common thread is that forests act as infrastructure, and when that living infrastructure is degraded, both drought and deluge hit harder.
Overlooked threats, from protected lands to fossil reserves
Even where forests are nominally protected, new pressures are emerging that could undermine their role as climate stabilizers. Jan Experts have issued an urgent warning over an overlooked threat to a vast swath of land, stressing that “[They] will die” if current plans move ahead. The concern centers on proposals to exploit fossil fuel reserves beneath or adjacent to forested areas, which could introduce large-scale industrial activity, pollution, and fragmentation into landscapes that currently store significant amounts of carbon.
While many forests are protected on paper, the same Jan Experts argue that legal status alone does not shield them from the potential pollution from the reserves, or from the roads and pipelines that would accompany extraction. Reporter Mandy Carr, writing on a Thu briefing, highlighted how these projects could release metric tons of greenhouse gases and destabilize ecosystems that are already stressed by climate change. The warning is stark: if They proceed, the resulting emissions and habitat loss could tip some forest regions from net carbon sinks into net sources, accelerating the very climate impacts that are already killing trees.
