Bumper crop trend continues for warm weather fruit in Kent, England - 0 views

  • KENT NEWS
  • While some producers are celebrating bumper crops courtesy of the early summer heatwave, others are advising producers look to embrace more exotic crops for long-term prosperity. Cherries are among this year’s big hits while wine producers are also raising a glass to the ideal conditions for their grapes. Although, ironically, it has proven too hot for some summer classics. Meanwhile, fruits traditionally associated with warmer parts of Europe – such as apricots, nectarines, and corn on the cob – are already being grown successfully here. There are even some variations on Kentish classics which are now blossoming. Apple varieties such as braeburn apples, which never used to survive in the UK, are already pushing out more traditional types. And scientists say it is all down to the effects of climate change.
  • Cheryl Martin, of Martin’s Organic Fruit Farm in Marden, said it had been a good year for cherries. “This year has been better than last year because we had all these long, hot days,” she said. She said the only problem to hit crops was the recent heavy downpours, which can cause ‘splitting’ on the cherries. Her farm sells produce wholesale to places including Choice Organic in London and Seasons in Forest Row. Biddenden Vineyards owner Julian Barnes said: “This year has been absolutely fantastic for us so far.” He said the warm, dry weather during flowering season meant that there were lots of grapes on the vines. The sun also creates more alcohol and of a better quality.

  • The vineyard also escaped the effects of the long, cold winter, he said: “We’ve been very lucky in this corner of the country. With the frosts in April and early May we got down to minus two very close to the buds being frosted off the vines. But not quite.” Now, Mr Barnes said he was hoping the weather stayed dry for the harvest at the end of September. Apples growers have also enjoyed the hot, sunny weather, but said the recent downpours were welcome. Sarah Calcutt, business development manager at Norman Collett, which markets English fruit from its base in Paddock Wood, said the extra light and warmth had been great for Rubens, a new variety of apples. “I’ve been out looking at orchards today with the National Fruit Show president and we’ve been particularly looking at Rubens. “We do not know if it will be a bumper crop yet because they won’t be picked until to September, but from an apple’s perspective the heat and sunshine in particular are great. “Photosynthesis is better with good light because it seeds the tree really well and gives it good energy for feeding themselves next year. A lot of day light hours are wonderful. “We’ve just had rain in time. One of the farmers who has no irrigation system said this bit we’ve just had came just in time for his young trees, which were starting to look a bit stressed. So the recent downpours have been fantastic.” However, organic fruit farmer Mrs Martin said that it had been a bad year for some fruits. “Raspberries are not looking very good this year. It was too hot for them and they were cooking on the plants,” she said. “But a little rain does everything good.” Dr Chris Atkinson, head of science at East Malling Research Centre, which has been collecting climate data since 1913, said the climate was a big determinate when growing fruit because temperature and rainfall had a big impact on crops. The climate data shows that the seasons have been getting longer and the winters are getting milder. “We can even answer sceptics about climate change – no one can argue that climatic data shows it is changing,” he said.
  • The centre has recorded increasingly milder winters and longer seasons. Dr Atkinson said the changing temperature should be used as an opportunity to explore new crops and spoke about someone who had successfully grown a banana outside in Cornwall.
  • “Apricots and nectarines on a commercial scale we believe will achieve economic gain in the UK rather than just surviving.” The centre is currently trialling hardy kiwis to see whether they can be grown as a crop.
  • Speaking about his own cherry trees in his garden, he said that this year they had produced more fruit than over the last 15.

Seabird populations drop by half in UK as climate change disrupts foodchain - 0 views

  • Climate change is starving Scotland’s seabirds into a drastic population decline that leaves some species dangerously close to extinction, the RSPB has warned. A major 10-year study by the Westminster Government’s conservation adviser found that the number of common gulls in the UK has fallen by almost half over the last decade. Scarcity of traditional food sources as sea temperatures rise may be forcing them to seek alternatives on land, which may be why residents of some seaside towns have complained that the birds, also called European herring gulls, are becoming more aggressive.
  • In its report, published today, the Joint Nature Conservation Committee (JNCC) says that over a decade the number of breeding kittiwakes has fallen by 40%, while there has been a 38% decline in fulmars. The biggest drop affects the common gull, however, with a 43% reduction in breeding pairs between 1999 and 2009.
  • The JNCC’s Population Trends and Causes of Change 2010 report uses UK-wide figures, with no regional breakdown available, but the RSPB said anecdotal evidence in Scotland seemed to confirm an impact north of the border. “Early reports of seabird breeding performances on RSPB Scotland’s coastal reserves unfortunately seem to reflect this worrying trend, with things particularly tough in the Northern Isles,” said Doug Gilbert, the charity’s Scottish reserves ecologist.

  • At the RSPB’s Orkney reserve, many kittiwake nests have been found abandoned. Arctic terns have also struggled in the Northern Isles, and failed to breed significantly this year. Gilbert said: “The most likely cause is a lack of food, especially for terns and kittiwakes, which feed on sandeels. “Worryingly, it looks like this problem is being driven by climate change affecting the marine ecosystem from the bottom up.”
  • Although herring gulls are among the most commonly encountered birds in Scottish towns and cities, particularly in coastal areas, they were added to the RSPB’s “red list” of at-risk species last year. The latest 43% decline in their numbers means an overall 25-year fall of at least 70%.

Sea cucumber population explosion off coast of Ireland - 0 views

  • long-term monitoring has shown that animal communities living at great depth on the seafloor can change radically over remarkably short periods, and that these events are ultimately driven by climate. Such faunal changes are exemplified by the 'Amperima Event' – the sudden mass occurrence of the sea cucumber (holothurian) Amperima rosea recorded on the Porcupine Abyssal Plain (PAP) situated off the southwest coast of Ireland in the northeast Atlantic. Communities of animals living on the seabed there at depths of nearly 5000 metres have been monitored from 1989 to the present day. A major change occurred in the PAP community between 1996 and 1999 involving a number of animal groups, including sea anemones, segmented worms, sea spiders, sea squirts, brittle stars, and sea cucumbers, all of which increased in abundance. However, the population explosion in the sea cucumber Amperima rosea (hereafter Amperima) was particularly striking – thus the 'Amperima Event'. Before 1996 the sea cucumber was found in only ones or twos. They were very rare. But by 1999, the sea cucumber reached such high densities that if you were able to walk on the deep seafloor, you would have difficulty in avoiding squashing them flat. Dr David Billet and his colleagues showed that the increase abundance and dominance of Amperima occurred over a very wide area, greater than the size of the UK. Changes are also apparent in the abundance of other animals living in the seabed, including the single-celled creatures inhabiting the sediments. The whole deep-sea world had been turned on its head. "What this strongly suggested," says Dr Billett, "is that the 'Amperima Event' did not simply reflect localised, chance changes in the abundances of one or two species. Instead, changes in the whole deep-sea animal community were driven by environmental factors."
  • "Whether it is the quality or the quality of the organic matter, or both, that matter," says Dr Billett, "it appears that changes in the density of animals such as Amperima are related to phytoplankton productivity in the overlying surface waters, which is affected by climate change."

Salmon, trout populations fall in Wales following hot, dry summers - 0 views

  • salmon numbers fell by 50 percent and trout numbers by 67 percent between 1985 and 2004, with the fish hit hardest following hot, dry summers such as during 1990, 2000 and 2003.
  • findings suggest warmer water and lower river levels combine to affect both species. As both trout and salmon favor cool water, they face potentially major problems if climate warming continues as expected in the next two to three decades.

Fog over San Francisco thins by a third due to climate change - 0 views

  • The coastal fog along the Californian coast has declined by a third over the past 100 years – the equivalent of three hours cover a day, new research shows. And it is not just bad for scenery, the reduction in the cooling effect of the fog could damage the health of the huge Redwood Forests nearby.
  • "Since 1901, the average number of hours of fog along the coast in summer has dropped from 56 per cent to 42 per cent, which is a loss of about three hours per day," said the study leader Dr James Johnstone at the University of California. He said that it was unclear whether this is part of a natural cycle of the result of human activity, but the fog is receding because of a reduction in the difference between the temperature of the sea and the land. "A cool coast and warm interior is one of the defining characteristics of California's coastal climate, but the temperature difference between the coast and interior has declined substantially in the last century, in step with the decline in summer fog," he added.
  • Professor Todd Dawson, co-author, said the decline could be disastrous for the nearby ecosystems.

  • "Fog prevents water loss from Redwoods in summer, and is really important for both the tree and the forest," he said. "If the fog is gone, we might not have the Redwood forests we do now."

Atmospheric shift due to warming reducing drag on satellites - 0 views

  • Space buffs know that Earth orbit is littered with junk, including defunct satellites, spent rocket boosters, and other random debris--about 11,500 objects bigger than 4 inches across
  • every one of these speeding bits of hardware could potentially damage, or even smash up a working satellite. The latter could create a lot more debris, potentially triggering something called the Kessler Syndrome, in which fragments of a smashed satellite go on to smash more satellites, creating fragments that go on to smash more...and so on.
  • turns out that if you warm the lower atmosphere by trapping infrared radiation--the essence of the greenhouse effect--the upper atmosphere should actually get cooler.
  • ...2 more annotations...
  • That's already been observed
  • Anyway, a new analysis out of the University of Southampton, in the U.K., points out that this cooling actually makes the upper atmosphere contract, removing some of the friction that eventually drags space junk back to Earth (and yes, believe it or not, there's a tiny bit of air in low-earth orbit, where the space junk problem is most acute). With less falling to Earth, there's more to slam into working satellites, the International Space Station and whatever else happens to be up there.

Unprecedented heat wave in Africa, Asia sets more all-time highs - 0 views

  • Extreme heat wave in Africa and Asia continues to set all-time high temperature recordsA withering heat wave of unprecedented intensity and areal covered continues to smash all-time high temperatures Asia and Africa. As I reported earlier this week, Saudi Arabia, Iraq, Chad, Niger, Pakistan, and Myanmar have all set new records for their hottest temperatures of all time over the past six weeks. The remarkable heat continued over Africa and Asia late this week. The Asian portion of Russia recorded its highest temperate in history yesterday, when the mercury hit 42.3°C (108.1°F) at Belogorsk, near the Amur River border with China. The previous record was 41.7°C (107.1°F) at nearby Aksha on July 21, 2004. (The record for European Russia is 43.8°C--110.8°F--set on August 6, 1940, at Alexandrov Gaj near the border with Kazakhstan.) Also, on Thursday, Sudan recorded its hottest temperature in its history when the mercury rose to 49.6°C (121.3°F) at Dongola. The previous record was 49.5°C (121.1°F) set in July 1987 in Aba Hamed.We've now had seven countries in Asia and Africa, plus the Asian portion of Russia, that have beaten their all-time hottest temperature record during the past two months. This includes Asia's hottest temperature of all-time, the astonishing 53.5°C (128.3°F) mark set on May 26 in Pakistan. All of these records are unofficial, and will need to be certified by the World Meteorological Organization (WMO). According to Chris Burt, author of Extreme Weather, setting six national heat records in one month is eight in one summer is unprecedented. The only year which can compare is 2003, when five countries (the UK, France, Portugal, Germany, Switzerland, and Liechtenstein) all broke their all-time heat records during that year's notorious summer heat wave. Fortunately, the residents of the countries affected by this summer's heat wave in Asia and Africa are more adapted to extreme high temperatures, and we are not seeing the kind of death tolls experienced during the 2003 European heat wave (30,000 killed.) This week's heat wave in Africa and the Middle East is partially a consequence of the fact that Earth has now seen three straight months with its warmest temperatures on record, according to NOAA's National Climatic Data Center. It will be interesting to see if the demise of El Niño in May will keep June from becoming the globe's fourth straight warmest month on record.

  • A CONSERVATION success which has seen barnacle geese numbers bounce back from the brink could be under threat from hungry polar bears struggling to cope with climate change, experts said yesterday. The number of Svalbard barnacle goslings that overwintered in the Solway Firth this year was just half that expected, according to the Wildfowl and Wetlands Trust (WWT).

  • geese in their summer breeding site, around Spitsbergen, Norway.Researchers, who have photographed bears in the nests and found evidence of "egg raids", say more polar bears are gathering around Spitsbergen and preying on the eggs because a reduction in Arctic ice is making it harder for them to hunt seals.
  • Brian Morrell, a zoologist based at the wildlife centre, said: "Our suspicion is that, as climate change reduces the polar ice-floe, making it harder for the bears to hunt their usual diet of seal, they are being driven by hunger to prey on nest sites.
  • "Obviously it takes a very large quantity of eggs to satisfy an animal as big as a polar bear, especially one with cubs."The impact is that entire nesting areas are being stripped bare of eggs and young, with potentially dire consequences for the geese and wildlife tourism."The bears could threaten the fortunes of the Svalbard barnacle geese population; there were just 300 birds in the 1940s, but now up to 30,000 visit Scotland each winter. The turnaround was the result of a ban on hunting, work on monitoring and the provision of a safe habitat for the geese at Caerlaverock, the WWT said.
  • Trust chief executive Martin Spray said: "It is a tragedy to witness two species of conservation concern clashing over the right to survive, and demonstrates the tensions the natural world is experiencing right now."

Hudson Bay polar bear population dropping with ice loss - 0 views

  • the ice has been melting earlier in the spring and forming later in the autumn, so that the bears are now spending on average three more weeks on land per year, without food, than they did three decades ago, the researchers say. As a consequence, their body weight in that time has dropped by 60lb, females have lost 10 per cent of their body length, and the west Hudson Bay population has declined from 1,200 animals to 900.

Russia declares state of emergency over wildfires driven by heatwave - 0 views

  • Russian President Dmitry Medvedev has declared a state of emergency in seven Russian regions because of wildfires fuelled by a heatwave. The death toll from the fires has risen to at least 34. The Russian emergencies ministry said 500 new blazes had been discovered over a 24-hour period, but most had been extinguished. Homes have been burnt in 14 regions of Russia, the worst-hit being Nizhny Novgorod, Voronezh and Ryazan. The state of emergency was announced in a decree that also restricted public access to the regions affected. Moscow is again shrouded in smoke from peat and forest fires outside the city. The fires, caused by record temperatures and a drought, have affected cereal harvests, driving wheat prices up.
  • Russians are bracing themselves for another week of high temperatures, with forecasts of up to 40C (104F) for central and southern regions. Officials also expect stronger winds in some regions, which will fan the flames. By Sunday night, wildfires were still raging across some 128,000 ha (316,000 acres).
  • Thousands of people have lost their homes and nearly a quarter of a million emergency workers have been deployed to fight the flames. President Medvedev described the situation on Saturday as a "natural disaster of the kind that probably only happens every 30 or 40 years". Moscow doctors say the elderly and toddlers should wear gauze masks outdoors.

You can't see it at all, just the river bank." More famous for its bitterly cold winters, the giant country's European part normally enjoys short, warm summers. However July was the hottest month on record. In Moscow, which sees an average high of 23C in the summer months, recorded 37.8C last Thursday.

Yangtze river flow fastest ever, torrential rain hits China - 0 views

  • The Three Gorges dam on China's longest river, the Yangtze, is standing up to its biggest flood control test since completion last year, officials say. Floodwaters in the giant reservoir rose 4m (13ft) overnight, and are now just 20m below the dam's maximum capacity.
  • The flow of the water overnight was the fastest ever recorded, at 70,000 cubic metres per second. Dr Cao Guangjing, head of China Three Gorges Corporation, told the BBC that 40,000 cubic metres/second were released, with 30,000 cubic metres/second of water held back in the reservoir.
  • More than 35 million people across China have been affected by the poor weather and 1.2 million have been relocated. China is facing its worst floods since 1998, when more than 4,000 people died, and 18 million people were displaced, the China Daily newspaper said.

Record sea surface temperatures in hurricane alley - 0 views

  • June SSTs in the tropical Atlantic set a new recordSea Surface Temperatures (SSTs) in the Atlantic's Main Development Region for hurricanes had their warmest June on record, according to an analysis I did of historical SST data from the UK Hadley Center. SST data goes back to 1850, though there is much missing data before 1910 and during WWI and WWII. SSTs in the Main Development Region (10°N to 20°N and 20°W to 80°W) were 1.33°C above average during June, beating the previous record of 1.26°C set in June 2005. June 2010 is the fifth straight record warm month in the tropical Atlantic, and the third warmest anomaly measured for any month in history. The only warmer anomalies were 1.51°C and 1.46°C, set in May 2010 and April 2010, respectively.

Global warming driving 40 per cent decline in the ocean's phytoplankton - 0 views

  • The dead sea: Global warming blamed for 40 per cent decline in the ocean's phytoplankton Microscopic life crucial to the marine food chain is dying out. The consequences could be catastrophic
  • The microscopic plants that support all life in the oceans are dying off at a dramatic rate, according to a study that has documented for the first time a disturbing and unprecedented change at the base of the marine food web. Scientists have discovered that the phytoplankton of the oceans has declined by about 40 per cent over the past century, with much of the loss occurring since the 1950s. They believe the change is linked with rising sea temperatures and global warming.
  • If the findings are confirmed by further studies it will represent the single biggest change to the global biosphere in modern times, even bigger than the destruction of the tropical rainforests and coral reefs, the scientists said yesterday.
  • ...3 more annotations...
  • Phytoplankton are microscopic marine organisms capable of photosynthesis, just like terrestrial plants. They float in the upper layers of the oceans, provide much of the oxygen we breathe and account for about half of the total organic matter on Earth. A 40 per cent decline would represent a massive change to the global biosphere."If this holds up, something really serious is underway and has been underway for decades. I've been trying to think of a biological change that's bigger than this and I can't think of one," said marine biologist Boris Worm of Canada's Dalhousie University in Halifax, Nova Scotia. He said: "If real, it means that the marine ecosystem today looks very different to what it was a few decades ago and a lot of this change is happening way out in the open, blue ocean where we cannot see it. I'm concerned about this finding."The researchers studied phytoplankton records going back to 1899 when the measure of how much of the green chlorophyll pigment of phytoplankton was present in the upper ocean was monitored regularly. The scientists analysed about half a million measurements taken over the past century in 10 ocean regions, as well as measurements recorded by satellite.They found that phytoplankton had declined significantly in all but two of the ocean regions at an average global rate of about 1 per cent per year, most of which since the mid 20th Century. They found that this decline correlated with a corresponding rise in sea-surface temperatures – although they cannot prove that warmer oceans caused the decline.The study, published in the journal Nature, is the first analysis of its kind and deliberately used data gathered over such a long period of time to eliminate the sort of natural fluctuations in phytoplankton that are known to occur from one decade to the next due to normal oscillations in ocean temperatures, Dr Worm said. "Phytoplankton are a critical part of our planetary life support system. They produce half of the oxygen we breathe, draw down surface CO2 and ultimately support all of our fishes." he said.But some scientists have warned that the Dalhousie University study may not present a realistic picture of the true state of marine plantlife given that phytoplankton is subject to wide, natural fluctuations."Its an important observation and it's consistent with other observations, but the overall trend can be overinterpreted because of the masking effect of natural variations," said Manuel Barange of the Plymouth Marine Laboratory and a phytoplankton expert.
  • However, the Dalhousie scientists behind the three-year study said they have taken the natural oscillations of ocean temperatures into account and the overall conclusion of a 40 per cent decline in phytoplankton over the past century still holds true. "Phytoplankton are the basis of life in the oceans and are essential in maintaining the health of the oceans so we should be concerned about its decline."It's a very robust finding and we're very confident of it," said Daniel Boyce, the lead author of the study."Phytoplankton is the fuel on which marine ecosystems run. A decline of phytoplankton affects everything up the food chain, including humans," Dr Boyce said.
  • Phytoplankton is affected by the amount of nutrients the well up from the bottom of the oceans. In the North Atlantic phytoplankton "blooms" naturally in spring and autumn when ocean storms bring nutrients to the surface. One effect of rising sea temperatures has been to make the water column of some regions nearer the equator more stratified, with warmer water sitting on colder layers of water, making it more difficult for nutrients to reach the phytoplankton at the sea surface.Warmer seas in tropical regions are also known to have a direct effect on limiting the growth of phytoplankton.
