    You can tell it’s climate conference season because that’s the time when – with 16% of the global temperature data for 2014 still missing – the World Meteorological Organisation (WMO) and the UK Met Office have a guess at (and a press release about) what the global annual temperature at the end of the year […]

    This is an impressive piece of climate research. So why did it not get more media coverage? Is it too cynical to suggest that whilst research showing that the Sun has little influence in contemporary climate change is reported with enthusiasm while work that points in the other direction is overlooked?   Just over three […]

    Some media outlets have been reporting that the oceans are starting to get warmer, and that it signals the end to the current hiatus in annual average global surface temperatures. Mother Nature Network says the pace of ocean warming is speeding up. “Earth’s ocean surface has been hotter in 2014 than any previous year on record, […]

    • Reporting Climate Science

    Daily data on Arctic sea ice extent shows that the area of ocean covered by sea ice is growing more strongly than in recent years. The latest report from the US National Snow and Ice Data Center (NSIDC) – see below – confirmed that sea ice extent in October remained off the floor.  On 3 November […]

  • False Alarm: Tropical Storm Intensity Not Increasing

    • Date: 13/11/14
    • Reporting Climate Science

    Despite predictions that global warming would lead to more powerful storms, a new study finds that there has been no increase in the intensity of tropical storms. Instead, the ongoing poleward migration of storms that has been apparent in recent decades and which acts to suppress storm intensity is offsetting the impact of increased global […]

    • Reporting Climate Science

    Research from the University of Leeds and an international team of scientists has shown a recent increase in atmospheric hydrogen chloride (HCl), a substance linked to destruction of the ozone layer. It was anticipated that there would be a decline in HCI under the Montreal Protocol, the international treaty designed to protect the ozone layer […]
