Anchovy could replace cod in British waters by 2050

Cod, herring and whelks can be driven out of British waters by 2050 as climate change continues to heat the seas, according to a damn new report.

The government-supported Marine Climate Change Impacts Partnership (MCCIP) has assessed how British waters and the animals living there will respond to rising temperatures in the coming 30 years.

According to the historical report, many loyal British fishermen will struggle to survive, while exotic newcomers may find a permanent home in our seas.

There are no existing guidelines or legislation for dealing with many of these new species, including the invading bluefin tuna, and experts predict that rapidly changing circumstances will turn the fishing industry upside down.

In the report, the authors say that a dramatic fall in the production of shellfish – particularly whelks and cockles in Wales – will cause “significant economic losses.”

They also discovered with ‘average confidence’ that the ongoing battle of cod, herring, whiting and sprat fishing is likely to continue.

In contrast, more tropical species such as anchovies, hake and sole will thrive.

However, fish will also become smaller because they have to spend large amounts of energy to travel further to find prey.

HOW DOES THE BRITISH SEA HEAT ON BIRDS AND MARINE MAMALS?

The government-supported Marine Climate Change Impacts Partnership (MCCIP) provides a picture of how British wildlife will respond to rising water temperatures.

It was established with ‘average confidence’ that ‘Leach’s petrel, great hunter and Arctic hunter could die out in the UK by 2100’.

It also claims that black-legged gull, northern tern and alken have a considerably smaller range and are forced to the north.

The breeding population is declining with some wader species related to warmer, drier summers.

Heating winter temperatures have also been associated with changes in the spring traffic of hibernating water birds to their breeding grounds.

Marine mammals with warm water species such as striped dolphin, short-beaked dolphin and beaked whale move north while the waters change.

And the ranges of cold-water species, such as white-beaked dolphin, are shrinking.

According to the report, the most important influences of climate change on marine mammals are probably from prey distribution and availability.

Species of marine mammals that make seasonal long-distance hikes (eg, most whale whales) are likely to arrive earlier or stay longer in large widths, thereby increasing breeding opportunities.

The report is divided into different categories to investigate the potential impact of global warming on the seas in the UK.

In addition to fish populations and their mortality rates, it investigates the potential impact on seabirds, waterbirds, marine mammals and plankton.

The scope of the comprehensive report extended to the study of the effects of sea ice, coastal habitats and weather patterns.

The final part of the analysis focused on how it would directly affect humans, with rising sea levels, threats to coastal heritage sites and an increased flood risk.

Previous data show that global warming is most pronounced in northern Scotland and in the North Sea, with a sea surface temperature of up to 0.24 ° C (0.43 ° F) per decade.

The report then predicts that the British seas will rise in temperature by a maximum of 0.4 ° C (0.72 ° F) every decade if emissions continue unabated.

In the future, the report expects the English Channel and the North Sea to be hit more strongly than other wetlands.

These warming temperatures have contributed to the melting of sea ice, which has contributed to the rise in sea level.

At least half of the loss of ice in the North Pole since the mid-20th century has been caused by climate change caused by humans.

Warmer waters and other factors have also contributed.

By 2050, if the emissions remain high, the report warns that the Arctic will become ice-free before 2050.

The impact of this on sea level will be catastrophic.

Since 1900, the average sea level around the UK has risen by 12-16 cm.

The sea level rise is slightly higher in the south of England and slightly lower in the north of Scotland.

By the end of the century, when the Arctic sea ice has disappeared, the sea level rise predictions in London can rise to 0.78 m.

It is expected that the British seas will not only heat up and rise, but will also become more acidic, less oxygen-rich and less salty, all important factors for marine life.

Cold-water fish such as the eelpout have already disappeared, while hot-water fish such as anchovies are recently in bloom, the report claims.

It is thought that the most important problem for many species is how fluctuating temperatures affect the timing of the release of species.

The authors write: “Global warming and associated oxygen solubility appears to affect the age of maturing, growth rate and the maximum size that fish can reach.”

A provisional ‘low confidence’ prediction also adds more care to the basic product that is cod.

In addition to whales, warm-water species that are popular with sea anglers, such as the Atlantic bonito (photo), will often visit English seas

It says that experiments have shown that Atlantic cod larvae can experience higher mortality rates due to ocean acidification.

In the last 30 years, however, mackerel has flourished in western Scotland.

The report states that by 2040, global warming is likely to lead to the invasive Pacific oyster in southwestern England, Wales, and Northern Ireland.

“By 2050, climate-driven changes in suitable available habitats could become a major constraint on the distribution of some commercial species in the North Sea,” the report claims.

If emissions remain at the current high level, this impact can be as serious as a 10 percent loss.

According to the report, human health also seems to be right as a result of rising temperatures.

Changes caused by warmer water and rising sea levels will cause changes in the way excess water is treated, possibly overloading the existing sewer infrastructure.

As a result, water used for “recreation and harvesting of shellfish” can be exposed to increased exposure to norovirus.

“Increasing sea temperature, more heat waves and reduced salinity are likely to increase the risk of human infections from Vibrio species,” the authors add.

But while many of the marine species are threatened, the warming weather conditions will also see that whale whales – including the whale and gray whale – spend more time in British waters, leading to potential tourist excursions.

In addition to whales, warm-water species that are popular with sea anglers, such as the Atlantic bonito, will often visit English seas.

Environment Minister Rebecca Pow told The Telegraph: “Tackling climate change and the impact on our environment is both a national and international priority, and the UK is already at the forefront of achieving this by our globally leading goal of achieving Net Zero greenhouse gas emissions by 2050.

“We will increase that momentum during this year’s COP26 discussions in Glasgow and we call on more countries to pledge with us to protect at least 30% of the ocean under protected marine areas by 2030.

“We are also investing £ 2.6 billion over a six-year period to better protect our communities against flooding and erosion.

EFFECTS OF RISING SEA TEMPERATURES ON BRITISH LIFE

FLOODING

The report states that previous improvements to flood defenses have reduced the social, economic and environmental impact of flooding.

However, the expected increase in extreme sea levels will significantly increase the flood risk on the coast if nothing is done first, the report claims.

A single and very possible sea level rise of 0.5 m means that up to 70 percent of coastal defenses in England and Wales become “very vulnerable” to failure.

By the 2080s, an expected annual damage from coastal flooding is estimated at £ 1.7b.

The combined threat of flooding due to sea level rise and storms makes transport and energy infrastructure on the coast particularly vulnerable.

An estimated 2,700 properties will be lost to coastal erosion in England over the next 50 years, even with the implementation of coastline management plans.

Without these plans, the number will rise to 28,000 homes.

TOURISM

Because whale bale whales are predicted to be in British waters, whale watching excursions can become a tourist feature.

Sea fishing could also become more popular because hot water fish such as the Atlantic bonito have been seen in British waters.

“Warmer summers are expected to result in more comfortable coastal conditions, extended tourism seasons, increased revenues, new infrastructure and more employment and water sports opportunities,” the report said.

But it does warn about the dangers of over tourism and the burden that outdated infrastructure systems can cause.

HERITAGE LOSS

Climate change increases the natural rate of decline for many culturally important locations.

It also threatens to increase the destruction of flooded shipwrecks, because the northward spread of Shipworm (Lyrodus pedicellatus), a wood-boring species that can cause structural damage, has been helped by water heating.

English Heritage and Historic Environment Scotland has stated that many coastal areas suffer from coastal erosion and flooding. This will only be annoyed by climate change.

Historical assets on the coast will be subject to increased erosion rates, increased flooding and changes in weather patterns as a direct consequence of climate change.

Future consequences of climate change will lead to the continuous loss of many historic assets in the coastal zone.

The same erosion processes will inevitably also lead to new discoveries, the report adds.

STORMS

Researchers say that the increase in storms in the last 70 years cannot be directly attributed to climate change.

But climate change can affect storms and waves in the North Atlantic.

However, this impact will fade in comparison with the natural variability of weather patterns.

The chance that severe storms will reach the UK in the fall may increase as a result of climate change as tropical cyclones become more intense.

The overall wave height will actually decrease by 2100, but heavy waves will be larger than they have historically been.

There is still a big question mark about how climate change will react to the weather and whether it will be noticeable compared to the natural variability in climate patterns.

COASTAL Erosion

A large proportion (17 percent) of the British coastline is currently affected by erosion.

This will almost certainly increase in the future due to a combination of factors, including human activity and sea level rise

In Scotland, for the first time since the last ice age, the rise in sea level surpasses the vertical land movement caused by post-glacial ‘rebound’ of the crustal, which increases coastal erosion.

Scottish firths will also all be exposed for the first time to increased erosion rates due to rising sea levels.

SEA LEVEL RISE

Since 1900, the average sea level in the UK has risen by around 12-16 cm.

The sea level rise is slightly higher in the south of England and slightly lower in the north of Scotland.

Towards the end of the century the sea level rise in London varies from 17 – 31 inches (0.45-0.78 m) depending on the greenhouse gas emission scenario and whether humanity can reduce its carbon footprint. .

Estimates for other cities are: Edinburgh 0.23-0.54 m; Cardiff 0.43-0.76 m; and Belfast 0.26-0.58 m.

SEA ICE LOSS

At least half of the loss of ice in the North Pole since the mid-20th century has been caused by climate change caused by humans.

Warmer waters and other factors have also contributed.

By 2050, if the emissions remain high, the report warns that the Arctic will become ice-free before 2050.
