UK has driest first six months of any year since 1929
As June ended with below average rainfall, official figures show that January to June had average rainfall of 356.8 mm, making this period the second driest for 100 years. 1929 had the driest first six months of a year, when 275.7 mm of rain was recorded. The drier conditions have been caused by a lack of Atlantic weather systems, which usually cross the UK bringing bands of rain, especially to western regions. The drier conditions have already led to pressure on water resources in some areas.
A recent (May 2010) Met Office study on how climate change could affect the frequency of extreme droughts in the UK found a range of possibilities — the majority of them showing such droughts will become more common. The study looked at how frequently extreme droughts could happen in the UK by 2100. To put the droughts in context, conditions seen in 1976 were used as a benchmark — a year which saw one of the worst droughts on record.
The Met Office climate model was used to run a number of simulations and these were then studied to determine how frequently 1976-style droughts could occur. There were 11 slightly different versions of the model, producing a range of results. At the lower end, extreme droughts would continue to be as rare as they are today — happening every 50 to 100 years. In the majority of other outcomes from the model, however, 1976-style droughts were more
frequent. At the higher end, extreme droughts could happen once every decade — making them about 10 times more frequent than today.
Eleanor Burke, Climate Extremes Scientist with the Met Office, said understanding how droughts will affect the UK in the future is vital for plans to adapt to climate change. She said: "Severe droughts such as the one seen in 1976 have a big impact — causing water shortages; health risks; fire hazards; crop failure, and subsidence. Understanding how the frequency of these events will change is therefore very important to planning for the future."
At this stage there is no probability attached to each of the scenarios, so they are all assumed to be equally likely. It is hoped future research will be able to assess how likely each outcome is to give better guidance to decision-makers on how they need to plan and adapt for future impacts of climate change.

Climate change and volcanic activity
The eruptions from the Eyjafjallajökull volcano in Iceland (Eyjafjallajökull means "glacier on the Eyja-mountain") and the recent earthquake in China has raised awareness in the media of the influence of climate change and atmospheric shifts on seismic activity. Whilst there is no evidence to link Iceland's eruption or the earthquake in China
to climate change, researchers are suggesting there is an increasing amount of evidence linking man made climate change to natural disasters such as landslides, earthquakes, tsunamis from underwater landslides and volcanic eruptions. Land "rebounding" as the weight of melting ice is removed and lower air pressure caused by typhoons could, for example, result in increased seismic activity.
This month researchers have warned in the Royal Society's Philosophical Transactions publication that the Earth’s crust could be affected by melting ice, sea level rises and even increasingly heavy storms and rainfall - predicted consequences of rising global temperatures. Researchers are
advocating more research to gain a better understanding of how contemporary climate change may drive hazardous geological and geomorphological activity, identify those parts of the world that are most susceptible and provide a more robust appreciation of potential impacts for society and infrastructure.
A summary of their research stated: "Periods of exceptional climate change in Earth history are associated with a dynamic response from the geosphere, involving enhanced levels of potentially hazardous geological and geomorphological activity. The response is expressed through the
adjustment, modulation or triggering of a broad range of surface and crustal phenomena, including volcanic and seismic activity, submarine and subaerial landslides, tsunamis and landslide 'splash' waves, glacial outburst and rock-dam failure floods, debris flows and gas-hydrate destabilization. In relation to anthropogenic
climate change, modelling studies and projection of current trends point towards increased risk in relation to a spectrum of geological and geomorphological hazards in a warmer world, while observations suggest that the ongoing rise in global average temperatures may already be eliciting a hazardous response from the geosphere."

£2.6 million flood protection grants for homes announced
The second round of a £5.5 million grant scheme to help households better protect their homes against flooding was announced on 11 March 2010 by Environment Minister, Huw Irranca-Davies. The Property Level Flood Protection Grant Scheme is part of the Government’s response to Sir Michael Pitt’s review of the
2007 floods. In this the second phase, £2.6 million will be allocated to 34 schemes in areas at high risk of flooding, enabling 532 households to benefit from practical flood protection solutions such as air bricks covers, storm porches, door guards and flood boards.
In the first round of funding, £3 million was made available to 25 local authorities to protect up to 593 properties across England. In this second round, South West local authorities awarded grants are: West Devon Borough Council, North Devon Council, Bath and North East Somerset Council, Teignbridge District Council, and Bournemouth Borough Council.

UK Marine projection pages and briefing notes added to the MCCIP website
To help users get the most out of the latest ‘UKCP09’ marine and coastal projections, new pages have recently been added to the MCCIP (Marine Climate Change Impacts Partnership) website. These pages are intended to highlight some of the key findings from UKCP09, to help the wider marine and coastal community
get the most out of the projections. Quick links to some of the most immediately relevant sections in the marine and coastal report (including maps) are provided, as well as links to the user interface. Two new summary notes, entitled ‘UKCP09 marine and coastal projections summary’
and ‘Key UKCP09 marine and coastal variables explained’ provide succinct, at-a-glance overviews of the new projections. These notes have been written by MCCIP in conjunction with the Met Office and UKCIP to help explain what the marine and coastal projections are, what is included, and why they are important for the UK marine and coastal community.
To access the new pages go to http://www.mccip.org.uk/projections.

Copenhagen
With the historic climate change conference COP15 (15th Conference of the Parties to the UN Framework Convention on Climate Change) taking place in Copenhagen this month, you can follow developments hour by hour on the 'Act on Copenhagen'
website www.actoncopenhagen.decc.gov.uk. You can register on that website for regular updates throughout the negotiations.
Act on Copenhagen is the online voice of the UK Government on Copenhagen, and will aim to cover as much as possible of what the UK delegation is doing in Copenhagen, as well as other activities relevant to the conference, through a choice of 5 stories every
day. If you would rather get a snapshot of the day, then you should visit www.decc.gov.uk, where you will see all main stories with links to further developments. The United Nations Framework Convention on Climate Change (Copenhagen) website is at http://unfccc.int.

Funding announced for local community flood protection
Local communities across England will benefit from £16 million funding to help them tackle surface water flooding, Environment Secretary Hilary Benn announced on 18 August 2009. £9.7M will help the top 77 local authorities develop surface water management plans where the consequences of surface water flooding are expected to be highest have been identified from new studies which model the effects of very severe rainfall. Such storms can occur anywhere and are expected to become more frequent in the future with climate change.
Funding will be in the form of area-based and capital grants between August 2009 and March 2011. South West local authorities to benefit are Bristol, Bournemouth, Gloucestershire, North Somerset, Plymouth, Somerset and Swindon. Local authorities for all other areas will also be able to bid for a share of £5 million to help them deal with known local flooding problems. Defra is also spending £1 million on making training, data and other tools available to help all local authorities manage flood risk.
The announcement can be found on Defra’s archived web page from this link: national archive - Defra - 18.8.09. The Environment Agency estimates that around two-thirds of the flooding (affecting 57,000 properties) in summer 2007 was due to surface water. Surface water flooding is also extremely difficult to predict as it is often a result of sudden localised rainfall events, and very small variations in the built environment can have significant effects
on the way water flows. Climate change projections indicate that intense rainfall events are likely to increase resulting in an increased risk of surface water flooding.
