• 2017: A Low-Level Year For Global Cyclone Activity

    • Date: 31/12/17
    • Paul Dorian, Vencore, Inc.

    While the Atlantic Basin experienced a very active tropical season in 2017, global activity was actually below-normal for the year by one type of measurement thanks to quiet seasons in the northern Pacific Ocean and throughout the Southern Hemisphere. The global “accumulated cyclone energy” as we close out the year is 78% of normal year-to-date […]

  • Global Temperature For November 2017 Continues Decline

    • Date: 24/12/17
    • Dr David Whitehouse, GWPF Science Editor

    At the moment the main question in the minds of those who study global temperature data is; how far are global temperatures going to fall in 2018? The record El Nino of recent years took global temperatures to unprecedented highs for the instrumental era. But comparisons with very strong El Ninos in the past are of […]

  • David Whitehouse: Cosmic Rays-Climate Link Found

    • Date: 19/12/17
    • Dr David Whitehouse, GWPF Science Editor

    Scientists at the Technical University of Denmark have discovered what they call a game changing result in understanding how cosmic rays from supernovae – exploding stars – can influence Earth’s cloud cover and thereby climate by being mediated by the Sun. The new findings are published in the journal Nature Communications. If confirmed it could […]

  • Global Ocean Cooling Continues

    • Date: 12/12/17
    • Ron Clutz, Science Matters

    The global cooling trend since the 2015/16 El Nino peak has resumed HadSST is generally regarded as the best of the global SST data sets, and so the temperature story here comes from that source, the latest version being HadSST3. The chart below shows SST monthly anomalies as reported in HadSST3 starting in 2015 through […]

  • Arctic Refreezes After Warm El Nino Year, Melting Pause Continues

    • Date: 04/12/17
    • Ron Clutz, Science Matters

    Latest observations show that Arctic sea ice extent has not declined in the last decade. Given the fluctuations in daily sea ice measurements, climatology typically relies on monthly averages. November daily extents are now fully reported and the 2017 November monthly results can be compared with years of the previous decade.  MASIE showed 2017 reached […]

  • David Whitehouse: A Poor Analysis Of The Pause

    • Date: 22/11/17
    • Dr David Whitehouse, GWPF Science Editor

    A new paper in Nature Climate Change concludes that the so-called pause in global surface temperatures never happened. The paper has been mentioned in a few media outlets. It claims that new data from the Arctic makes the pause go away – and so it seems until you look at the paper in a little more detail […]

  • Stable Snow Cover On The Tibetan Plateau Over 2000–2015

    • Date: 14/11/17
    • Xiaoyue Wang et al., Nature

    No widespread decline in snow cover since 2000 Understanding the changes in snow cover is essential for biological and hydrological processes in the Tibetan Plateau (TP) and its surrounding areas. However, the changes in snow cover phenology over the TP have not been well documented. Using Moderate Resolution Imaging Spectroradiometer (MODIS) daily snow products and the […]

  • La Nina Has Arrived And Moves Into The Winter

    • Date: 09/11/17
    • USA Today

    La Niña, the cooler sibling of El Niño, is here. The La Niña climate (sic) pattern — a natural cycle marked by cooler-than-average ocean water in the central Pacific Ocean — is one of the main drivers of weather in the U.S. and around the world, especially during the late fall, winter and early spring. […]
