#RisingSeaLevels - Rising sea levels around Ireland due to climate change are almost 7cm since the early 1990s.

The Irish Examiner writes that this is due to the rising temperature of the planet, greenhouse gas emissions (GHGs) and the melting of glaciers.

And the next five to 15 years is a crucial time period within which to act if we want to halt any permanent changes to the planet.

According to the Environmental Protection Agency (EPA), climate change is most obvious in our changing sea levels.

The newspaper also writes that the number of high quality rivers has halved.

“Observed climate change impacts are most evident in the global temperature record, sea-level rise, loss of glaciers and ice sheets and changes in the nature and intensification of precipitation events,” the EPA report states.

“Since 1993, average sea level has risen around Ireland by just over 3cm per decade,” the report reads.

#MarineScience - Applications are invited from postgraduate students of marine science, atmosphere and climate-based sciences worldwide to participate in the Atlantic Ocean Climate Scholars Programme in Galway from 12-20 September 2016.

This intensive, accredited workshop will examine how climate and oceans interact, with particular examples from the Atlantic Ocean and higher latitudes.

The programme will be led by an international team of research leaders in climate science with contributions from policy makers and researchers in the field.

A number of scholarships are available to cover travel and accommodation expenses and the deadline for applications is this Friday 3 June 2016.

The relationships between human activities and the oceanic and atmospheric processes that drive our climate will be investigated in the context of the latest IPCC Assessment Report published in 2013.

Critical elements of the global climate system will be scrutinised with special reference to the Atlantic Ocean and its ecosystems. Ocean observation programmes, new technologies, and model outputs will be evaluated in the context of societal and governmental responses to climate change.

Workshop activities will include presentations, field trips and practical data sessions.

Applicants can apply online until 1800 UTC on Friday 3 June. Further information is available by emailing [email protected] or [email protected].

The Atlantic Ocean Climate Scholars Programme is a collaboration between the Strategic Marine Alliance for Research & Training (SMART) based in GMIT, NUI Galway, the Alfred Wegener Institute (AWI), the Partnership for the Observation of the Global Ocean (POGO), the Helmholtz Climate Programme REKLIM and is supported by the Nippon Foundation.

#ClimateChange - Models to predict the future climate indicate that global temperatures will rise by an average of as much as 4.5C by the end of this century, bringing a rise in sea levels and changes to rainfall patterns.

And these changes in the weather are already being felt in Ireland, according to Met Éireann's head of climatology Séamus Walsh, who says that even slight shifts, such as an increase in the number of warm days over 20C, have "a knock-on effect on natural ecosystems" that have adapted to Ireland's climate.

"Fragile habitats in vulnerable upland, peatland and coastal areas will come under increasing stress," he adds, noting also a 5% increase in rainfall over the last three decades, more so in the West and North West.

"Climate projections for rainfall have greater uncertainty than for temperature," he explains. "They indicate that overall rainfall amounts in Ireland might decrease slightly, summers are likely to become drier while winters may be wetter, especially in the west and north."

There are also indications of an increase in the number of very wet days – days with rainfall over 20mm – which means that such projections, when applies to river flows, show "an increased risk of winter flooding, an increased risk of short duration ‘flash’ floods and to possible water shortages in summer months due to higher temperatures and lower rainfall.

"The rise in sea levels will make low lying coastal areas more prone to flooding, especially from storm surges," he adds.

#MarineScience - Climate change is rapidly warming lakes around the world, threatening freshwater supplies and ecosystems, according to a new study spanning six continents.

More than 60 scientists took part in the research, published in the journal Geophysical Research Letters and announced at the fall meeting of the American Geophysical Union on Wednesday 16 December.

The study – based on global analyses including unique long-term data from the Marine Institute's catchment research facility at Newport, Co Mayo – found that lakes are warming an average of 0.34C, or 0.61F, each decade.

That's greater than the warming rate of either the oceans or the atmosphere, and it can have profound effects, the scientists say.

At the current rate, algal blooms – which can ultimately rob water of oxygen – are projected to increase 20 percent in lakes over the next century. Algal blooms that are toxic to fish and animals would increase by five percent.

These rates imply that emissions of methane, a greenhouse gas 25 times more powerful than carbon dioxide, will increase four percent over the next decade.

"Lakes are important because society depends on surface water for the vast majority of human uses," said co-author Stephanie Hampton, director of Washington State University's Center for Environmental Research, Education and Outreach.

"Not just for drinking water, but manufacturing, for energy production, and for irrigation of our crops. Protein from freshwater fish is especially important in the developing world."

Temperature is one of the most fundamental and critical physical properties of water. It controls a host of other properties that include intricate living processes that have evolved within strict boundaries.

When the temperature swings quickly and widely from the norm, life forms in a lake can change dramatically and even disappear.

"These results suggest that large changes in our lakes are not only unavoidable, but are probably already happening," said lead author Catherine O'Reilly, associate professor of geology at Illinois State University.

Earlier research by O'Reilly has seen declining productivity in lakes with rising temperatures.

Funded in part by NASA and the National Science Foundation, the study is the largest of its kind and the first to use a combination of long-term hand measurements and temperature measurements made from satellites, offsetting the shortcomings of each method.

Study co-author Simon Hook, science division manager at the NASA Jet Propulsion Laboratory, said satellite measurements provide a broad view of lake temperatures over the entire globe. But they only measure surface temperature, while hand measurements can detect changes in temperature throughout a lake. Also, satellite measurements go back only 30 years while some lake measurements can go back more than a century.

Lough Feeagh in Co Mayo was one of 235 lakes in the study that have been monitored for at least 25 years. While that's a fraction of the world's lakes, they contain more than half the world's freshwater supply.

The Marine Institute measures the surface water temperature of Lough Feeagh as part of the long term ecological monitoring of the Burrishoole catchment. The Burrishoole research station is an internationally important index site for diadromous fish monitoring, and water temperature is a crucial variable controlling growth, migration and survival of salmon, trout and eel in the catchment.

"The inclusion of data from Lough Feeagh in this study highlights the value of collecting local environmental long term data to inform global analyses," said Dr Elvira de Eyto, a biologist at the Marine Institute facility in Burrishoole and one of the studies co-authors.

Marine Institute chief executive Dr Peter Heffernan added: "The sharing of such data with global scientific networks makes an important contribution to worldwide climate change analyses, and our understanding of how the warming climate will affect our valuable aquatic resources."

The surface water of Lough Feeagh has warmed at a rate of 0.35C per decade between 1985-2009, although the rate of warming was lower than some other northern hemisphere lakes.

"We want to be careful that we don't dismiss some of these lower rates of change," said Hampton. "In warmer lakes, those temperature changes can be really important. They can be just as important as a higher rate of change in a cooler lake."

The researchers said various climate factors are associated with the warming trend. In northern climates lakes are losing their ice cover earlier, and many areas of the world have less cloud cover, exposing their waters more to the sun's warming rays.

Many lake temperatures are rising faster than the average air temperatures. Some of the greatest warming is seen at northern latitudes, where rates can average 0.72C, or 1.3F, per decade.

Warm-water, tropical lakes may be seeing less dramatic temperature increases, but increased warming of these lakes can still have large negative impacts on fish. That can be particularly important in the African Great Lakes, home to one-fourth of the planet's freshwater supply and an important source of fish for food.

In general, the researchers write: "The pervasive and rapid warming observed here signals the urgent need to incorporate climate impacts into vulnerability assessments and adaptation efforts for lakes."

Bray, Co Wicklow was the location for a unique Climate Change event on Friday (20th November) hosted by Seán Kelly MEP on the importance of achieving a global deal to reduce carbon emissions in Paris next month.

"I am honoured to have been chosen to be part of the delegation that will represent the European Parliament at the global UN Climate Change Conference in Paris in December and will be the only Irish MEP to do so. We received our mandate with a huge majority from the Parliament last month and we are ready to work in Paris to get our key points across," Mr Kelly told attendees.

"Climate Change is truly one of the key challenges of this century. Failure to address it effectively will result in major adverse impacts that will affect all countries.

"Ireland, for example, is particularly vulnerable to loss of coastal assets due to rising sea levels, along with increased precipitation and the resulting flood risks - all of these would prove hugely costly, both socially and economically.

"The bottom line is, we need an ambitious and binding global agreement and we will push for that in Paris. If EU ambition is matched globally, we keep jobs and economic growth here, while meeting the 2oC objective," the MEP added.

Climate change is a cross sector challenge according to Mr Kelly which requires a concerted global effort. "We need to take action to limit these temperature increases, but we have a challenge to do so while meeting the parallel challenges of ensuring food security and maintaining EU competitiveness."

"The bottom line is, we need an ambitious and binding global agreement and we will push for that in Paris. If EU ambition is matched globally, we keep jobs and economic growth here, while meeting the 2oC objective," he said.

Event speakers included Jean-Pierre Thebault, French Ambassador to Ireland, Eamon Ryan, Leader of the Green Party, Mauro Poinelli, Head of Unit Environment, Forestry and Climate Change, European Commission, who examined the agricultural side of the debate and Neil Walker, IBEC’s Head of Infrastructure, Energy and Environment who presented the Irish business perspective.

#MarineWildlife - Climate change is driving fish species away from the tropics for more hospitable, warming waters elsewhere, according to scientists from the University of British Columbia.

RTÉ News has more on the story, which outlines that even in the best case scenario, the waters of the tropics are set to warm by one degree Celsius, promoting fish to migrate some 15 kilometres every decade towards the Arctic and Antarctic.

The Canadian university researchers used climate modelling based on findings from the past few decades to predict the situation for more than 800 fish species and marine invertebrates – and the results could be catastrophic for all coastal communities as the ecosystem changes.

#MarineWildlife - "What if whales were nature's ultimate geoengineers?" That's the question Philip Hoare poses on the Guardian's Comment Is Free section upon the news that US scientists have identified cetacean waste as a potentially pivotal link in the climate change chain.

Marine scientists from the University of Vermont compiled decades' worth of research in their new report that claims whale faeces – and deceased whales on the ocean floor – might comprise "massive carbon sinks" absorbing the CO2 human industry puts into the environment while also providing nutrients for other marine wildlife.

Indeed, it's now thought that areas where cetacean populations have shown signs of recovery after decades of hunting are also seeing "higher rates of productivity" among commercial fishing species.

The new report also supports the notion that climate change "may have been accelerated by the terrible whale culls of the 20th century" that removed a necessary balancing effect to counter the huge levels of man-made carbon emissions.

As Hoare writes: "A burgeoning global population of cetaceans might not just be good for the whalewatching industry, they may play a significant role in the planet's rearguard action against climate change."

#Jellyfish - Jellyfish are coming to Ireland's shores in bigger numbers than ever before, as the Belfast Telegraph reports.

The "worrying" finding comes with the latest figures of the annual Coastwatch survey of the island of Ireland that concluded in mid October.

Stats collected from volunteers around the coast show that jellyfish have been sighted in more areas and in greater numbers than any other time in the 25-year history of the survey - most likely the result of climate change.

Among them was an "absolutely enormous" specimen more 5 feet in diameter, found on the West coast.

"What this says to us is that our waters are warming," said Coastwatch International co-ordinator Karin Dubsky, who highlighted an explosion in the numbers of small brown jellyfish "which do a lot of damage to wildlife".

#POWER FROM THE SEA - Marine-based renewable energy projects could be introduced without a damaging impact on marine wildlife, according to a new briefing paper from Friends of the Earth.

Business Green reports on the paper from the environmental campaign group, written by marine ecologist Martin Attrill of Plymouth University's Marine Institute, which draws together research on the biodiversity impact of offshore wave energy, tidal energy and wind power schemes.

Attrill found that the deployment of sea energy arrays could ultimately benefit many marine species by reducing the effects of fishing activity, and even acting as reefs to attract new sea life.

He cites the example of a grey seal colony in Strangford Lough that has steered clear of a nearby tidal turbine over the three years of its operation in the lough.

However, Business Green says the report makes clear that the deployment of such projects "must be done sensitively", noting that any negative impact on biodiversity "would be significantly lower than the damage done to marine wildlife by rising sea levels caused by climate change".

Brendan Smith TD, Minister for Agriculture, Fisheries and Food visited (Saturday 2nd Oct) the Marine Institute laboratories in Co. Mayo to see at first hand the important work being carried out by the Institute in collaboration with UCD and Trinity College on the impacts of climate change. This work has been developed as part of the NDP funded RESCALE project (Review and Simulate Climate and Catchment Responses at Burrishoole) and involves the development of computer models to assist land use and fisheries managers to deal with impacts of climate change on sensitive peatland river catchments. In an Irish context this is the first time that Global Climate Models have been downscaled to a catchment scale and the work has clearly shown that in addition to milder winters and warmer summers we can also expect more frequent flood events in the west of Ireland by the 2080's. Inland Waterways

Launching the publication of the final report on RESCALE project, Minister Smith said that the project was a major milestone in our understanding of the effects of climate change on sensitive upland catchments in the west of Ireland. "While global climate change is a worldwide phenomenon, the research findings in this report provide information at the local level that will be invaluable to fisheries and land use managers," said the Minister. "Practical research work such as RESCALE is essential if we are to plan for the future management of our valuable agriculture, fisheries and forestry resources in the west of Ireland."

The project is studying data from an unbroken record of information on water temperature, air temperature, river discharge, rainfall and a host of other factors which exists for the catchment dating back to the 1950s for the Burrishoole river. This information collected at the Furnace facility and the neighbouring Met Eireann synoptic station, is invaluable as a resource, not only for measuring physical change over the past sixty years, but also as a proven yardstick to "ground-truth" any computer-generated models describing the likely effects of global warming. Minister Smith said "I am very impressed with the work being done here in Newport and the high level of collaboration between the Institute and the Universities on marine research and its practical application to real situations to help inform decision making into the future."

About Dublin Port 

Dublin Port is Ireland’s largest and busiest port with approximately 17,000 vessel movements per year. As well as being the country’s largest port, Dublin Port has the highest rate of growth and, in the seven years to 2019, total cargo volumes grew by 36.1%.

The vision of Dublin Port Company is to have the required capacity to service the needs of its customers and the wider economy safely, efficiently and sustainably. Dublin Port will integrate with the City by enhancing the natural and built environments. The Port is being developed in line with Masterplan 2040.

Dublin Port Company is currently investing about €277 million on its Alexandra Basin Redevelopment (ABR), which is due to be complete by 2021. The redevelopment will improve the port's capacity for large ships by deepening and lengthening 3km of its 7km of berths. The ABR is part of a €1bn capital programme up to 2028, which will also include initial work on the Dublin Port’s MP2 Project - a major capital development project proposal for works within the existing port lands in the northeastern part of the port.

Dublin Port has also recently secured planning approval for the development of the next phase of its inland port near Dublin Airport. The latest stage of the inland port will include a site with the capacity to store more than 2,000 shipping containers and infrastructures such as an ESB substation, an office building and gantry crane.

Dublin Port Company recently submitted a planning application for a €320 million project that aims to provide significant additional capacity at the facility within the port in order to cope with increases in trade up to 2040. The scheme will see a new roll-on/roll-off jetty built to handle ferries of up to 240 metres in length, as well as the redevelopment of an oil berth into a deep-water container berth.

Dublin Port FAQ

Dublin was little more than a monastic settlement until the Norse invasion in the 8th and 9th centuries when they selected the Liffey Estuary as their point of entry to the country as it provided relatively easy access to the central plains of Ireland. Trading with England and Europe followed which required port facilities, so the development of Dublin Port is inextricably linked to the development of Dublin City, so it is fair to say the origins of the Port go back over one thousand years. As a result, the modern organisation Dublin Port has a long and remarkable history, dating back over 300 years from 1707.

The original Port of Dublin was situated upriver, a few miles from its current location near the modern Civic Offices at Wood Quay and close to Christchurch Cathedral. The Port remained close to that area until the new Custom House opened in the 1790s. In medieval times Dublin shipped cattle hides to Britain and the continent, and the returning ships carried wine, pottery and other goods.

510 acres. The modern Dublin Port is located either side of the River Liffey, out to its mouth. On the north side of the river, the central part (205 hectares or 510 acres) of the Port lies at the end of East Wall and North Wall, from Alexandra Quay.

Dublin Port Company is a State-owned commercial company responsible for operating and developing Dublin Port.

Dublin Port Company is a self-financing, and profitable private limited company wholly-owned by the State, whose business is to manage Dublin Port, Ireland's premier Port. Established as a corporate entity in 1997, Dublin Port Company is responsible for the management, control, operation and development of the Port.

Captain William Bligh (of Mutiny of the Bounty fame) was a visitor to Dublin in 1800, and his visit to the capital had a lasting effect on the Port. Bligh's study of the currents in Dublin Bay provided the basis for the construction of the North Wall. This undertaking led to the growth of Bull Island to its present size.

Yes. Dublin Port is the largest freight and passenger port in Ireland. It handles almost 50% of all trade in the Republic of Ireland.

All cargo handling activities being carried out by private sector companies operating in intensely competitive markets within the Port. Dublin Port Company provides world-class facilities, services, accommodation and lands in the harbour for ships, goods and passengers.

Eamonn O'Reilly is the Dublin Port Chief Executive.

Dublin Port is creating a distributed museum on its lands in Dublin City.
 A Liffey Tolka Project cycle and pedestrian way is the key to link the elements of this distributed museum together.  The distributed museum starts at the Diving Bell and, over the course of 6.3km, will give Dubliners a real sense of the City, the Port and the Bay.  For visitors, it will be a unique eye-opening stroll and vista through and alongside one of Europe’s busiest ports:  Diving Bell along Sir John Rogerson’s Quay over the Samuel Beckett Bridge, past the Scherzer Bridge and down the North Wall Quay campshire to Berth 18 - 1.2 km.   Liffey Tolka Project - Tree-lined pedestrian and cycle route between the River Liffey and the Tolka Estuary - 1.4 km with a 300-metre spur along Alexandra Road to The Pumphouse (to be completed by Q1 2021) and another 200 metres to The Flour Mill.   Tolka Estuary Greenway - Construction of Phase 1 (1.9 km) starts in December 2020 and will be completed by Spring 2022.  Phase 2 (1.3 km) will be delivered within the following five years.  The Pumphouse is a heritage zone being created as part of the Alexandra Basin Redevelopment Project.  The first phase of 1.6 acres will be completed in early 2021 and will include historical port equipment and buildings and a large open space for exhibitions and performances.  It will be expanded in a subsequent phase to incorporate the Victorian Graving Dock No. 1 which will be excavated and revealed. 
 The largest component of the distributed museum will be The Flour Mill.  This involves the redevelopment of the former Odlums Flour Mill on Alexandra Road based on a masterplan completed by Grafton Architects to provide a mix of port operational uses, a National Maritime Archive, two 300 seat performance venues, working and studio spaces for artists and exhibition spaces.   The Flour Mill will be developed in stages over the remaining twenty years of Masterplan 2040 alongside major port infrastructure projects.
