A combination of climate change, extreme weather and pressure from local human activity is causing a collapse in global biodiversity and ecosystems across the tropics, new research shows. The study mapped over 100 locations where tropical forests and coral reefs have been affected by climate extremes such as hurricanes, floods, heatwaves, droughts and fires.

The grim effects that climate change will have on pediatric health outcomes was the focus of a recent article.

As we discussed yesterday, the current pattern over the North Atlantic and European continent is supporting blocking ridge over Europe but very deep trough across the North Atlantic. The associated surface low / extra-tropical low is more or less covering the whole North Atlantic, resulting in widespread windstorms and indeed some spectacular satellite presentation – […]

The new stratospheric warming phase is set to start this week. It will greatly reduce the strength of the stratospheric polar vortex. Considering that we will be in February by then, the polar vortex will not recover to previous strength. The animation below shows the stratospheric polar vortex forecast, at 5mb level (~35km altitude), where […]

Northeastern Russia (Yakutia region, Siberia) is a well-known place for extreme cold, with the Verkhoyansk Range being the coldest area in the Northern Hemisphere. Oymyakon and Verkhoyansk are the towns where record cold low temperatures are at 67.8 °C and -71.2 °C. This weekend, the pattern over that part of Asia brought a strong upper-level […]

The weather pattern across North Atlantic and Europe has not changed much since mid-December, there are constant deep and often violent extra-tropical cyclones developing. While the European continent is under the effect of upper-level blocking ridges, high-pressure systems, and mild weather. This weekend, yet another monster cyclone is dominating the North Atlantic with a pronounced […]

The western United States has experienced such intense droughts over the past decade that technical descriptions are becoming inadequate. In many places, conditions are rocketing past "severe," through "extreme," all the way to "exceptional drought."

Data collected are providing crucial new insights for scientists seeking to minimize the impacts of severe weather and climate change on wildlife.

Policies and new technologies have reduced emissions of precursor gases that lead to ozone air pollution, but despite those improvements, the amount of ozone that plants are taking in has not followed the same trend, according to researchers.

Predicting a major transition, such as climate change, is extremely difficult, but a new probabilistic framework is the first step in identifying the path between a shift in two environmental states.

The strengthening upper-level ridge across west-central Europe is underway, the atmospheric pressure has already risen towards 1050 mbar across parts of United Kindom. The mid-1040s are reported across France, Benelux and W Germany, near 1040 mbar over the Alps and Denmark. The highest surface pressure is expected tonight, likely reaching 1050-1051 mbar in some parts […]

The post Jan 19th, evening UPDATE: surface pressure readings across UK Wales and Ireland are reporting 1048-1049 mbar and rising – *above 1050 mbar* expected tonight appeared first on Severe Weather Europe.

Half of winter is already behind us. This is usually the time when we take a first look at spring, to see what the early projections are and what to expect. We are also going to have a look at how the last winter month, February, might look. If you are interested in the theory […]

While a large part of Europe is expecting an extremely high-pressure system with pressure readings 1045-1050 mbar until Thursday, there is a very interesting but dangerous feature developing – a deep upper-level low over the Iberian peninsula. It was re-developed from the North Atlantic wave we have been monitoring on Friday – the cyclone was […]

This morning, a huge temperature difference occurred over Finland. The extreme north Lapland station Utsjoki Nuorgam reported -36 °C while the capital Helsinki in far south Finland reported +5 °C – that is 41 °C difference! This huge temperature contrast over Finland is the result of advection of very cold air mass from Arctic Russia […]

The significant pattern flip is underway across Europe as an extensive upper-level ridging – Rex block is developing this weekend. Surface pressure reading across UK and Ireland is already reaching the upper 1030s and rising, expected to push very near 1050 mbar by Monday morning. Pressure should rise above 1045 mbar also across central Europe […]

As we discussed yesterday, yet another explosive development of the extra-tropical cyclone was expected today. An upper wave ejected from eastern Canada into the Northwest Atlantic and deepened, resulting in explosive cyclogenesis at the surface. The satellite presentation is simply outstanding and reveals some very interesting details of the Arctic air mass advection behind the […]

Like we didn’t have ridging pattern for several weeks now, there is an exceptional event coming in the next days. A very strong upper-level ridging develops over eastern parts of North Atlantic, expanding into western and central Europe. As a result, an associated surface high-pressure system develops and brings *extremely* high surface pressure. A large […]
