Climate Change and Rainfall in Ireland

53.0N 9.1W

April 6th, 2013 Category: Climate Change

Ireland – April 3rd, 2013

This image focuses on the Republic of Ireland and the country of Northern Ireland (UK). Like much of the planet, Irish weather conditions have undergone significant changes in recent years. Of the fifteen warmest years on record in Ireland, ten of these have occured since 1990. The average temperature has increased by 0.7 ºC during the period 1890-2004. It continues to rise.

There is also a general trend of significant increase of rainfall in Ireland along the north and west coasts, and only slight increases along the east and south coasts. Here, sediments can be seen in the Irish Sea, off the east coast of the country. In some cases, there has even been a decrease in rainfall. Increased rainfall may result in more seasonal flooding.

Rising sea levels are also of concern for Ireland , as waters have been rising by 2 – 4mm each year. If this trend continues, the sea level will have risen to 0.2 – 0.4m by the end of this century. Approximately 60% of the population are living within 10km of the coast. Areas of soft coastline, especially in the east, are under severe threat from erosion and flooding.

These changes, bringing the milder winters and warmer summers we have been experiencing in recent years, may be appreciated, but the impact in some parts of the world has been much more devastating. If climate change continues at such a high rate, Ireland is likely to be affected by the following: air temperature will rise by 1.5-2 degrees by 2080; rainfall will increase in winter and decrease in summer; sea temperatures may rise by 2 degrees by the end of the century, causing intense, agressive storms; flooding and erosion from extreme weather conditions; and altered agricultural practices, especially crop growing, to cope with weather changes (click here for more information).

Phytoplankton Bloom West of Ireland

United Kingdom - May 25th, 2012

Phytoplankton

Smoke or haze can be observed over the Irish Sea (center), Celtic Sea (lower left quadrant) and English Channel (lower right quadrant). The skies over the United Kingdom and Ireland, however, are mostly clear, offering an unusually clean look at the area. Visible in the full image and the close-up is an elongated phytoplankton bloom in the Atlantic to the west of Ireland.

Offshore Turbines of Robin Rigg Wind Farm in Solway Firth, United Kingdom – November 25th, 2011

November 25th, 2011 Category: Image of the day

United Kingdom - November 8th, 2011

This orthorectified image shows the  Solway Firth, a firth that forms part of the border between England and Scotland, between Cumbria (including the Solway Plain) and Dumfries and Galloway. It stretches from St Bees Head, just south of Whitehaven in Cumbria, to the Mull of Galloway, on the western end of Dumfries and Galloway. The Isle of Man (visible at the lower left of the full image) is also very near to the firth.

The firth comprises part of the Irish Sea. The coastline is characterised by lowland hills and small mountains. It is a mainly rural area with fishing and hill farming (as well as some arable farming) still playing a large part in the local economy.

Visible in the center of the firth are a series of dots arranged in parallel lines (best observed in full image). These are the turbines of the Robin Rigg Wind Farm, Scotland’s first offshore wind farm, which has been constructed in the Firth, on sandbank midway between the Galloway and Cumbrian coasts.

The construction of the windfarm began in 2007, and it was finally completed on 20th April 2010. Sixty Vestas V90-3MW wind turbines have been installed, with an offshore electrical substation. The 180 MW development will provide enough electricity for about 117,000 households.

 

Sediments in Irish Sea and English Channel – April 3rd, 2011

52.7N 5.6W

United Kingdom, Ireland, France - March 23rd, 2011

Sediments color the waters of the Irish Sea (left, between Ireland and Great Britain), the English Channel (center right, between England and France) and the North Sea (upper right, beyond the Channel).

The sediments trailing out into the North Sea come from the River Thames, and are quite concentrated in the river’s estuary. On the opposite coast, to the west, darker tan sediments from the River Severn flow into the Bristol Channel.

Sediments near the coast of France come from rivers such as the Couesnon (left of the large peninsula) and the Seine (right of the peninsula).

The Isle of Man and the Solway Firth

Isle of Man and Solway Firth, UK - May 11th, 2009

Isle of Man and Solway Firth, UK - May 11th, 2009

The Isle of Man (bottom) is a self-governing Crown dependency, located in the Irish Sea at the geographical centre of the British Isles.  The island is not part of the United Kingdom (nor of the European Union) but foreign relations, defence, and ultimate good-governance of the Isle of Man are the responsibility of the government of the United Kingdom.

Approximately 32 miles (51 km) long and between 8 miles (13 km) and 15 miles (24 km) wide, the island has an area of around 221 square miles (570 km2).

In the Irish Sea northeast of the Isle of Man is the Solway Firth, a firth (large sea bay) that forms part of the border between England and Scotland. The coastline of the Solway Firth is characterised by lowland hills and small mountains.

The firth’s water itself is generally benign with no notable hazards except some large areas of salt and mud flats which often contain dangerous patches of quicksand that move on a regular basis. Here, its upper reaches appear dark brown from mud flats and from sediments flowing into the firth from the River Waver and the River Wampool.
