51.60312 -1.11334 Met Office Assessed Class 4 and Good Installed 1/1/1960
This site is in the grounds of UK Centre for Ecology and Hydrology. Until 2011 it was located approximately 50 metres to the east of the above being moved to accommodate the 3,000 panel (700MW) Howbery Solar Farm. Unlike Chertsey Abbey Meads at least the screen was moved and not simply built around. So has relocating the screen only a small distance from the panels avoided any temperature and humidity distortions?
Rather implausibly it was originally assumed that solar farms would likely reduce local average temperatures by absorbing solar insolation. Increasingly, however, new empirical research has revealed the complete opposite, solar farms create their own variant of an urban heat island effect.
The Photovoltaic Heat Island Effect: Larger solar power plants increase local temperatures
As the above research points out, actually taking physical readings and site observations trumps computer modelling every time. Whether or not the Met Office has ever actually tested such sites alongside solar farms is not clear, however, their response to my inquiry regarding the Chertsey site indicates downgrading as follows
“The weather station was originally given a CIMO 2 rating for temperature, however, following the installation of the solar panels this rating was adjusted to CIMO 3 in line with World Meteorological Organisation guidelines for screen temperatures due to the artificial heat sources and reflective surfaces.”
In the absence of the solar panels at Wallingford, it would be likely assessed CIMO Class 2 or may possibly even Class 1 instead it is now rated Class 4. This makes any comparison of data post solar farm installation with prior readings unrealistic – apples with oranges.
Notably in the Met Office response, there was no specific reference to heat island effects generated by solar farms. This is of particular importance regarding the ever increasing location of solar panels alongside Met Office sites. Weather stations sites are often on government owned land and should be surrounded by flat open space i.e. ideal locations for solar farms. Wallingford and Chertsey are no longer exceptional and there are several other projects in hand. RAF Leconfield (to be reviewed shortly) has been severely compromised by “Project Prometheus” an initiative to spread to more sites around the country , inevitably in the vicinity of more weather stations.

Yet again, though, as in the case of Llandwddyn:Cwm Cownwy there is another official Met Office weather station under 2 kilometres away. In this case the CIMO rated Class 1 and Excellent Benson site which has been continuously reporting since 1951. Tim Channon reviewed Benson in the days before the Met Office was obliged to release (but only under FOI request) its CIMO assessments and correctly predicted its Class 1 rating. This raises the same questions as those from the Welsh site, if there is a First Class site so close by why bother to use readings from an unacceptably low rated site known to have a wide error margin and distorted historic record?

Google Gemini boldly asserts that there has been an increase in hurricanes due to the burning of fossil fuels. There is zero evidence to support any of this propaganda.
“there is strong scientific consensus that the increasing intensity and frequency of hurricanes are linked to climate change, which is primarily caused by the burning of fossil fuels.”
Just having fun

Vice President Kamala Harris’s changing statements on fracking have become an important issue in the current U.S. presidential election campaign. Only five years ago, Harris pledged to ban fracking, a drilling technique that has helped make the U.S. the world’s top producer of oil and natural gas. Today, the Democratic nominee says she supports fracking, with many political analysts attributing the shift to the political importance of winning Pennsylvania’s electoral votes. Pennsylvania is a major center of U.S. natural production through fracking.
However, the issue goes well beyond Pennsylvania; it also has vast implications for the U.S. economy and energy security of the U.S. and its allies. Moreover, fracking can also be restricted indirectly, without a formal ban. Indeed, the Biden-Harris administration has limited fracking by indirect means, such as special taxes on natural gas production and halting new exports of liquified natural gas (LNG). Thus, the question to Vice-President Harris should not be, will you halt fracking, but will you continue the Biden-Harris administration policies that curb natural gas production and have made production more expensive.
To be sure, the question of whether Harris will adhere to her 2019 commitment to “ban fracking” is relevant to in Pennsylvania, widely viewed as the most important battleground state and home to 20% of U.S. natural gas output. Fracking provides more than 100,000 jobs to Pennsylvania residents and generates more than over forty billion dollars in state revenue. No doubt Harris’s views on fracking will affect her prospects for election in the Keystone State.
However, limitations on natural gas production through fracking, also affect all Americans. The significant increase in natural gas production beginning in the early 2000s enabled by fracking, has helped greatly lower U.S. electricity and heating costs. This has given America an important competitive edge in manufacturing, enticing many companies to relocate to the U.S. from Europe and other places where energy costs are higher.
Fracking has turned the U.S. into a net natural gas exporter, which has brought in revenue and generated jobs. The U.S. emergence as the top producer of natural gas and top global exporter of LNG has also carried significant geopolitical ramifications, enabling the U.S. to guarantee reliable gas supplies to allies and making the gas accessible to developing economies to substitute coal, such as Pakistan. Europe was able to weather several winters after Russian gas supplies dwindled following its Ukraine invasion, due to a surge in U.S. LNG exports.
As part of its climate agenda, the Biden-Harris administration imposed extensive limitations on U.S. natural gas production, while not explicitly banning fracking. These measures raised costs and thus reduced investment attractiveness of U.S. natural gas production. As part of their limitations on natural gas, the Biden-Harris administration imposed a “methane” tax (methane is the main component in natural gas) as part of the 2022 Inflation Reduction Act, the administration’s feature climate law. In addition, the administration imposed a slew of new regulations on methane, that added many layers of bureaucracy to natural gas production, which both generates costs and cause production delays.
To gain favor with young voters by boosting its climate credentials, in January the Biden-Harris administration halted new permits for LNG export to countries that do not have free trade agreements with the U.S., and thus require federal government approval. In July, a federal court overturned the ban, but since then no new permits have been issued. Almost counterintuitively, a ban on LNG exports can lead to long-term price increases in the American natural gas market, since without new export as an anchor for demand, some investors are likely to flee and thus production could decrease in the U.S.
In addition, the Biden-Harris LNG export ban has raised questions about whether the U.S. can be counted on as a reliable supplier; in its wake several potential customer countries signed new import agreements with Qatar and Oman. Even if the ban is eliminated in the future, the decision shook the international gas market, as importers understood that a change in a U.S. administration or policy could put their energy supplies at risk.
Low natural gas prices are essential to lowering inflation and retaining an American manufacturing edge. Natural gas prices feed into the costs of almost all products, since natural gas is the major source of electricity in the U.S. A rise in power cost, translates to a rise in the costs of manufactured goods. In addition, natural gas is the feedstock of fertilizer, thus price rises in natural gas, translate to higher food costs.
Thus, the real question to ask Vice President Harris is whether she will continue the Biden-Harris polices and taxes that affect natural gas production and export. The is important to the United States, and not just Pennsylvania. It is relevant not only to jobs in Pennsylvania, but the trajectory of inflation and of the American economy.
