UHI in the UK raises Tmin by 1.7C

UHI causes Tmin go  up by 1.7C in UK

The observed increase in T min can be attributed to an increased intensity of the UHI during the hours after sunset and into the night. Many studies have previously shown that UHII is maximised during the night (Arifwidodo and Tanaka, 2015; Montávez et al., 2000; Ripley et al., 1996). The intensity is maximised during these hours, as heat absorbed by urban structures will be re‐radiated back into the atmosphere at a slower rate, due to smaller sky views, than natural structures. Further, the increase in impervious surface in an urban area causes a reduction of the latent heat flux and a rise in the sensible heat flux (Zhou et al.,2014). This leads to a difference between the rates at which the urban and natural area will cool during the night, with urban areas sustaining a higher temperature into the night. With minimum temperatures often occurring at night, the slowed rate of cooling in urban areas results in an increase of the observed minimum temperature.

HADCET Feb 2019 Mean Temperature Tied For 15th Warmest / MAX was hottest

Published on by sunshinehours1Leave a comment

You remember  HADCET (Central England Temperature)? Longest temperature record in existence!.

HADCET Feb 2019 was tied for 15th warmest out of 357. 

1779,1869,1990,1998,1794,1903,1945,2002,1867,1872,1961,1739,1914,1926 were warmer

And 2019 was tied with 1702,1750 and 1997.

The barplot is the February’s since 1659. The temperature is the anomaly from the 1659 to 2019 average.

The yellow bars are the years warmer than February 2019. Green bars indicate a tie with February 2019.

HADCET only goes back to 1878 for MIN and MAX. Here are those graphs.

Feb 2019 MAX was highest ever. MIN was tied for 47th.

 

 

EU Commission accused of £4.8bn miscalculation over renewable energy subsidies bill

Published on by sunshinehours1Leave a comment

Missed it by just a little …

John Constable of the Global Warming Policy Forum (GWPF) claims the EU Commission climate policy report contains a “substantive error”, miscalculating the cost of annual levies on UK consumers by £4.8 billion.

He said the initial bill claimed subsidies would be £1.3bn, when the correct figure is closer to £6.1bn.

Mr Constable also received a confirmation from the commission that the error would be rectified.

A spokesman for the EU Commission said: “You are correct that the largest part of the other subsidies was from the Renewables Obligation and that these were not allocated to ‘financed by end users’ as they should have been.

“Thank you for spotting this error, we are correcting the figures and expect a revised report to be online soon.”

Mr Constable said the miscalculation will have “consequences for all sections” of the report’s overall findings and estimates.

He said: “The study is an important and major statement on the economic consequences of the EU’s energy and climate policies, and it is crucial that such work is as accurate as possible.”

UK: Maybe Some Sanity on the Wood Pellet Issue?

Published on by sunshinehours1Leave a comment

1,000,000,000£ subsidy for burning wood pellets might be scrapped?

Controversial subsidies for burning wood in power stations could be scrapped in the drive to clean up Britain’s air.

Firms that burn wood pellets currently receive about £1billion a year because, unlike coal, these are considered renewable sources of energy.

But critics say burning wood produces similar amounts of carbon dioxide to coal, contributing to air pollution.

It also increases the logging of forests in the US, while shipping them to Britain in vast quantities has a further negative effect on the environment.

Environment Secretary Michael Gove yesterday revealed subsidies for burning wood could be scrapped as he unveiled the Government’s clean air strategy.

The U-turn comes after years of state support for ‘biomass’ such as wood pellets, in schemes pioneered by disgraced former Liberal Democrat energy secretary Chris Huhne. 

He was hired by US firm Zilkha Biomass, which makes wood pellets, after serving a prison sentence in 2013 for perverting the course of justice.

The clean air strategy includes proposals to scrap some subsidies paid under so-called ‘contracts for difference’.

The contracts, which last until 2027, offer payments of about £100 per megawatt hour for burning imported wood – more than double the wholesale energy price.

Britain’s biggest power station, Drax, near Selby, North Yorkshire, burns about 7million tons a year of compressed wood pellets imported from the US and Canada.

UK: Wind farm turbines last only 12-15 years

Published on by sunshinehours11 Comment

They sell you a dream of wind turbines lasting 25 years and they really last 12. And make you pay and pay and pay for them. What a con.

The analysis of almost 3,000 onshore wind turbines — the biggest study of its kind —warns that they will continue to generate electricity effectively for just 12 to 15 years.
The wind energy industry and the Government base all their calculations on turbines enjoying a lifespan of 20 to 25 years.

The study estimates that routine wear and tear will more than double the cost of electricity being produced by wind farms in the next decade.
Older turbines will need to be replaced more quickly than the industry estimates while many more will need to be built onshore if the Government is to meet renewable energy targets by 2020.

The extra cost is likely to be passed on to households, which already pay about £1 billion a year in a consumer subsidy that is added to electricity bills.

Wind turbines. Who exactly does Mr Barker think he is calling swivel-eyed?

UK Green Campaigners Furious!!! Outraged!!!

Published on by sunshinehours11 Comment

No shortage of phrases that are supposed to elicit anger at the government … but they just make me grin. Solar panels are subsidized by the poor.

The Government is closing an energy payment scheme which will mean homes with solar panels could be giving their excess power to the grid for free, provoking outrage among campaigners.

The Department for Business, Energy and Industrial Strategy Department (Beis) has announced the closure of the ‘export tariff’ scheme.

It pays householders for excess power that is fed back into the grid, to new solar generators from next April.

The closure of the scheme has prompted fury among green campaigners with Dr Doug Parr, chief scientist for Greenpeace UK, describing it as ‘simply perverse‘.

Does replacing coal with wood lower CO2 emissions? Nope.

Published on by sunshinehours13 Comments

Burning wood makes more CO2 than coal.

The conclusions high points:

  • biomass used to displace fossil fuels injects CO2 into the atmosphere at the point of combustion and during harvest, processing and transport.
  • the first impact of displacing coal with wood is an increase in atmospheric CO2relative to continued coal use
  •  before breakeven, atmospheric CO2 is higher than it would have been without the use of bioenergy, increasing radiative forcing and global average temperatures, worsening climate change, including potentially irreversible impacts that may arise before the long-run benefits are realized.
  • biofuels are only beneficial in the long run if the harvested land is allowed to regrow to its pre-harvest biomass and maintained there.
  • The carbon debt incurred when wood displaces coal may never be repaid if development, unplanned logging, erosion or increases in extreme temperatures, fire, and disease (all worsened by global warming) limit regrowth or accelerate the flux of carbon from soils to the atmosphere.
  • harvesting existing forests and replanting with fast-growing species in managed plantations can worsen the climate impact of wood biofuel.
  • growth in wood harvest for bioenergy causes a steady increase in atmospheric CO2 because the initial carbon debt incurred each year exceeds what is repaid.
  • using wood in electricity generation worsens climate change for decades or more even though many of our assumptions favor wood

Electric Cars – 40,000 Children Working in the Mines From Hell

Published on by sunshinehours11 Comment

Electric cars aren’t so clean.

Picking through a mountain of huge rocks with his tiny bare hands, the exhausted little boy makes a pitiful sight.

His name is Dorsen and he is one of an army of children, some just four years old, working in the vast polluted mines of the Democratic Republic of Congo, where toxic red dust burns their eyes, and they run the risk of skin disease and a deadly lung condition. Here, for a wage of just 8p a day, the children are made to check the rocks for the tell-tale chocolate-brown streaks of cobalt – the prized ingredient essential for the batteries that power electric cars.

And it’s feared that thousands more children could be about to be dragged into this hellish daily existence – after the historic pledge made by Britain to ban the sale of petrol and diesel cars from 2040 and switch to electric vehicles.

Dorsen and 11-year-old Richard are pictured. With his mother dead, Dorsen lives with his father in the bush and the two have to work daily in the cobalt mine to earn money for food.
