    No climate problem in Pakistan.
    2 Separate Studies Affirm No Net Temperature Or Precipitation Change In Pakistan Since The 1700s
    By Kenneth Richard on 1. April 2024

    Yet another region of the world has failed to cooperate with then anthropogenic global warming narrative.
    Asad et al., 2024

    “The longest 10 years’ warm periods were observed during the early decades of the twentieth century (AD 1918–1927…)…”

    “The five hottest years (based on 7.33 °C ± 0.99 °C) were AD 1896 (9.80 °C), 1892 (9.44 °C), 1898 (9.40 °C), 1871 (9.24 °C), and AD 1925 (9.23 °C)…”

    “Our reconstruction failed to capture the recent warming trend…”

    “In this study, we develop a regional chronology (RC) spanning from 1620 to 2017 CE by utilizing dendrochronological techniques and tree-ring data from two stands of Abies pindrow. The RC reveals a significant positive correlation (p < 0.05) with self-calibrated Palmer drought severity index (scPDSI) and precipitation and a significant negative correlation with temperature.”

    “Our reconstruction shows a significant correlation with the South Asia Summer Monsoon Index (SASMI), Atlantic Multi-decadal Oscillation (AMO), ENSO, Pacific Decadal Oscillation (PDO), and solar activity, emphasizing that all these factors have some influence on the drought variability in central-northern Pakistan.”

    So much for the (imaginary) threat of sea level rise.
    Sea Level Rise Alarm? The Coastlines Of 13,000 Studied Islands Net GREW Seaward From 2000-2020
    By Kenneth Richard on 4. April 2024

    The sea level rise experienced in recent decades was supposed to lead to shrinking shorelines and inundated coasts. Instead, satellite observations reveal the globe’s island coasts expanded seaward (net) by 402 km² since 2000.
    In a new study, over 13,000 islands were assessed for coastal change over the last three decades (1990-2020). Only 12% of these islands experienced significant shoreline change during this period. Thus, approximately 88% of the islands had stable coasts − neither substantial erosion or accretion.

    About 6% of these 13,000+ islands experienced coastline expansion (accretion), while 7.5% lost coastal land area (erosion). The scientists point out that, for the islands experiencing coastal erosion in recent decades, sea level rise was not a primary or predominant causal factor. This is “contrary to initial assumptions.”

    “Moreover, the data results suggest that sea-level rise has not been a widespread cause of erosion for island shorelines in the studied region. Presently, it is considered one of the contributing factors to shoreline erosion but not the predominant one.”

    “Contrary to initial assumptions, our empirical data does not conclusively link the widespread erosion of island shorelines primarily to historical sea-level rise, suggesting that human activities might mask the effects of sea-level rise.”

    Somewhat consistent with the alarming sea level rise narrative propagated by anthropogenic global warming (AGW) activists, there was indeed a net loss (-259.33 km²) of coastal land area for the 13,000+ islands studied in the decade spanning 1990 to 2000. But then, “in the subsequent decades, the trend reversed, with net increases of 369.67 km² from 2000 to 2010 and 32.67 km² from 2010 to 2020.”

    Added together, in the last two decades the globe’s island coasts net grew seaward by 402.33 km² from 2000-2020, and coasts grew by a net 157.21 km² for the entire 30-year period (1990-2020).

    “Over the past three decades, the entire region experienced a cumulative increase in land area of 157.21 km² across more than 13,000 islands.”

    “…over the past 30 years, fewer islands experienced landward erosion compared to those undergoing seaward accretion.”

    Sea level rise thus cannot be an explanation for the contradictory three decades of net coastal seaward expansion observations.

    But if the recent decades of sea level rise trends cannot even be considered a primary or predominant factor contributing to coastal erosion either, then the alarmist sea level rise narrative necessarily disintegrates under the weight of the evidence.

    Yep. Atolls and many other coastal areas accrete commensurate with or faster than sea level rise—especially if humans don’t alter natural vegetation and build sea walls etc.

    The average climate crisis actor doesn’t realize fossil fuel use has actually increased coastal land areas over the last decades. Or that areas actually threatened by sea level rise actually are suffering from subsidence and lost accretion caused relative sea level rise, not absolute sea level rise from increased ocean volume.

    It’s sad because then people try to solve problems with solutions that can never fix the problem.
