A Christian attitude in these precarious times

Today, on ‘From Guestwriters’, we published a reader’s question about the Christian stance in these chaotic times.

In any case, recent months have certainly brought us plenty of issues that could cause concern. In Ukraine, Russia’s inhumane conflict with its southern neighbour continues unabated, whilst the Russian government spares neither person nor property. So we see ‘Gog’ advancing southwards, whilst the rest of the world hears about it, watches, but does very little to prevent this advance.

It was not only Europe that had to contend with a great many natural disasters this summer. There was the severe drought, but this was offset by violent hailstorms and torrential downpours. Many countries were ravaged by storms, landslides and mudslides. Climate change meant we had to experience its dangerous consequences first-hand. Melting glaciers made their power felt and seen with great force.

Those who read the Bible regularly are certainly not surprised by any of these events. The Bible warns us that difficult times are to come, with an increase in natural disasters and more violence amongst people. These days, even minors do not shy away from stabbing others or shooting them dead.

In the face of all these events, we must ask ourselves how we should observe all this and whether or not we should respond. We are convinced that we cannot stand by and watch silently from the sidelines. As followers of Christ, we must live by his teachings and, out of love for our fellow human beings, we are called upon to take active action.

As Christians, we cannot simply stand by and watch all these events unfold. We must not only make our voices heard, but also roll up our sleeves and get stuck in.

As children of God, we can trust that Jehovah is willing to give us gifts to help others. We must therefore make practical use of the gifts we receive from God. It is not only within our own church community that we should allow these spiritual gifts to flourish. We must open ourselves up to God’s gifts in such a way that we may grow in wisdom and spiritual strength. We must understand why God has given us these gifts. It is not so that we should do nothing with them. In the same way, we must have the courage to reach out and speak to people about our faith and our hopes for the future.

The basis for putting these gifts into practice lies in understanding their purpose. They are a manifestation of the qualities with which God is prepared to endow people. They enable us, as believers, to overcome our own uncertainty and fear and to maintain a biblical perspective on the future. In this way, we are offered opportunities to serve God and to help further build up the body of Christ and bring it to maturity.

We must share the gifts we receive through God’s Spirit with others, both within the church community and beyond, with love.

In all expressions of spiritual gifts, priority must be given to love. The apostle Paul explains that even extraordinary gifts — speaking in tongues, prophecy, knowledge and faith — mean nothing without love. We must be aware that spiritual power, separated from love, becomes spiritual arrogance.

++

The question posed: How should Christians use their spiritual gifts today?

“Widespread shallow landslide events constitute one of the primary drivers of recurrent societal and economic losses in mountain regions. Although the influence of climate variability on landslide frequency and magnitude has been widely recognized, long-term, event-level analyses linking spatiotemporal landslide patterns to precipitation climatology at the regional scale remain scarce. This study presents a statistical analysis of 128 widespread shallow landslide events recorded in Piedmont, northwestern Italy, over the 66-year period 1960–2025, cross-referenced against the regional precipitation climatology. Events were characterized by season, primary physiographic unit, provincial coverage, and an ordinal magnitude index (scale 1–7) encoding combined spatial extent and estimated landslide count. Results indicate that no statistically significant monotonic trend in event frequency was detected over the study period (mean rate: 1.97 events yr⁻1); however, a moderate positive correlation was established between event magnitude and the number of provinces affected (R2 = 0.51, p < 0.00), validating the magnitude index as a proxy for spatial footprint. Mean event magnitude reached its highest value in the 2010s (3.71), while all five events of magnitude ≥ 6 occurred in autumn. The summer fraction of the catalogue increased markedly, from 6% in the 1960s to 31% in the 2000s and 25% in the 2020s, concurrent with stable or declining summer mean precipitation totals, consistent with Clausius–Clapeyron amplification of convective intensity under documented regional warming. Cross-analysis with regional records identifies three tiers of rainfall–landslide coupling: a stationary direct seasonal coupling; a non-stationary, strengthening intensity-mediated summer coupling; and a structural susceptibility-mediated spatial decoupling whereby the driest provinces generate the highest landslide occurrence frequencies due to the lower triggering thresholds characteristic of Tertiary Piedmont Basin sedimentary environments. A post-hoc assessment of the triggering thresholds used for regional shallow landslide early warning system demonstrates superior detection performance for high-magnitude autumn events (hit rate up to 89% for the 2000–2025 sub-period) and identifies sub-daily convective accumulation windows in summer as the primary domain requiring threshold recalibration…”

“Nepal lies within an active seismic zone and is influenced by most dynamic climatic systems in the world. It faces compounding floods and landslide threats. Impacts are worst where multi-hazard interactions create spatially linked corridors. Despite frequent co-occurrence, national-scale assessments remain limited. This study presents machine learning and GIS-based approach to map nationwide susceptibility to floods, landslides, and identify their potential interaction zones, and delineate critical multi-hazard flow zones through spatial adjacency analysis. Using Google Earth Engine, the Random Forest model integrates topographic, climatic, environmental, and hydrological datasets to overcome subjective expert-driven methods. The model achieved strong predictive accuracy (AUC: 0.84 for floods, 0.85 for landslides). The results showed 19% of Nepal’s lowlands are medium to very highly susceptible to inundation, threatening approximately 900,000 people and over 3.4 million buildings; whilst in the hilly terrains, 40% is susceptible to slope-failure endangering 200,000 people and about 0.6 million buildings. K-means clustering followed by spatial adjacency analysis identified four spatial zonation: 81% of national area as low-hazard zone, 9% as flood-only zone, 5% as landslide-only zone, and 5% as interaction zones. Critical multi-hazard flow zone covering 7,588 km² represents spatially connected corridors linking interaction zones to downstream flood-prone populated areas, affecting 88 km² built-up land and 1,722 km² cropland. These zones represent susceptibility-based spatial connectivity rather than physically simulated cascading processes. These findings support recommendations for risk-informed land-use planning, resilient infrastructure development and climate adaptation aligned to sustainable development and investment risk screening…”

“In hilly regions transitioning rapidly to low gradient alluvial plains, localized hydrometeorological triggers can instantly scale into devastating basin wide disasters. This study dissects the September 2020 cascading hazard in parts of the Arunachal Pradesh-Assam corridor to quantify the rapid coupling between upstream hillslopes and downstream floodplains…”

“Extreme precipitation in the Eastern Himalaya is increasingly associated with coupled hillslope-floodplain hazards. This study examines the 17th-18th September 2020 rainfall event in Arunachal Pradesh initiating landslides and its downstream impacts in Assam, India, using multi-sensor satellite data and long-term rainfall records. Sentinel-2 imagery was used to map landslides and debris flows, Sentinel-1 SAR data to delineate flood extent, and IMD gridded rainfall (1996–2020) to analyse rainfall spell characteristics. The event triggered widespread slope failures, localized landslide damming, and a subsequent breach, generating sediment-laden flows that inundated ~ 100 km2 of the Dhemaji floodplain. A backscatter-derived Relative Flood Volume Index (RFVI) indicates spatial variability in inundation intensity, although it does not represent absolute flood volume. Rainfall analysis suggests that antecedent wetness from preceding spells preconditioned slopes, while peak daily rainfall (> 170 mm/day/) initiated landsliding. Power-law scaling shows negligible dependence of intensity on duration (R² ≈ 0.0004), whereas cumulative rainfall exhibits a stronger relationship with duration (R² ≈ 0.54). These results indicate distinct roles of rainfall intensity and accumulation in controlling landslide initiation and downstream flooding, respectively, highlighting the importance of compound rainfall forcing in rapid hydrogeomorphic cascades...”

Predicting Landslide Speeds

Knowing what speed a landslide will reach helps us predict how much damage they can cause. That speed depends on many factors: the steepness of the terrain, the sliding distance, the thickness of the flowing layer, and the type of grains making up the flow. Researchers found that predictions from previous studies often underestimated the speeds reached by thicker flows. Through laboratory experiments with grains of different shapes, a team found that those models mistakenly assumed a fully-developed flow — in other words, one where the grains have reached a constant final speed. While spherical grains reach that state over a short sliding distance, that’s not the case for other grains.

Instead, the team used their results to build a new predictive model for landslide speeds. This one still depends on incline angle and flow thickness, but it also uses a dynamical friction coefficient to describe the granular material and capture how the flow’s speed varies with distance down the incline.

It seems every Republican's wet dream of California sliding into the ocean is already happening...

https://www.youtube.com/watch?v=n0TjcmNsjPE

But don't forget that Florida is now a Swiss cheese of sinkholes and is just a few feet of sea level rise from also disappearing into the ocean.

Meanwhile California has millions of acres of land well above sea level should a coastal retreat ever be needed. Florida... not so much.
