Florida wakes up to climate change

The Guardian - Tue, 2016-04-19 06:30

The city of Miami Beach is slowly disappearing under water. At the big high tides of the year the sea washes over the famous wide beach and floods many of the city streets and magnificent Art Deco buildings. And over the past decade the floods have been striking more frequently.

Most of the city sits just a few feet above sea level, built on a foundation of porous limestone, allowing the rising seas to seep into the city’s foundations, surge up through pipes and drains, encroaching on fresh water supplies and saturating infrastructure. The city is now investing in a $500m project to raise roads and a pumping system to hold back the floods.

Sir David MacKay obituary

The Guardian - Mon, 2016-04-18 23:55
Cambridge physicist and government scientific adviser with a rational approach to the climate and energy debate

Sir David MacKay, who has died of cancer aged 48, was a true polymath, a rare breed in today’s world, where the frontiers of scientific knowledge are increasingly remote and complex. It is a testament to David’s intellectual brilliance that he was able to contribute to advancing more than one of these frontiers during his short career.

David latterly achieved cult status among climate and energy aficionados following the publication of Sustainable Energy: Without the Hot Air (2008), initially self-published using £10,000 of David’s own money and offered – as were all his works – simultaneously free for download on his website. Described as a “tour de force” by the Economist magazine and lauded by Bill Gates as “one of the best books on energy that has been written”, within two years it had sold 40,000 copies and been downloaded nearly half a million times.

More than 1,000 diesel cars caught without pollution filter, figures show

The Guardian - Mon, 2016-04-18 00:32

Government urged to crack down on rogue practice of garages removing compulsory diesel particulate filters from vehicles

More than a thousand diesel cars have been caught without an essential pollution filter that traps deadly particles, according to government figures. But experts warn the rogue practice of removing the filters, which contributes to air pollution-related deaths, could be far more widespread.

Almost 29,000 people die prematurely each year in the UK owing to particle pollution, causing £15bn in health costs. Since 2009 diesel particulate filters (DPFs) have been compulsory in new diesel cars. But, particularly for cars driven in cities, the DPFs can become clogged and cause breakdowns.

RRS Boaty McBoatface wins poll to name £200m polar research vessel – video explainer

The Guardian - Mon, 2016-04-18 00:22

The Natural Environment Research Council have conducted a poll to help decide the name of its new £200m polar research vessel and the winning name is – RRS Boaty McBoatface – receiving 124,109 votes. Four times more than RRS Poppy-Mai, which came in second place. Despite the overwhelming result of the poll, the NERC are unlikely to use the winning name. The government says it wants a name that ‘reflects the serious nature of the science it will be doing’

Boaty McBoatface wins poll to name polar research vessel

The Guardian - Sun, 2016-04-17 21:45

NERC chief has final say and faces dilemma between credibility of the organisation and burden of public opinion

Latest: Boaty McBoatface may not be name of new polar research vessel

Forget the EU referendum. The major test of modern democracy has fallen into the hands of the Natural Environment Research Council – over the naming of a boat.

As the polls finally closed for the naming of its new polar research ship, the NERC confirmed that the votes were overwhelmingly in favour of RRS Boaty McBoatface.

Clouds gather over solar power after golden years of success

The Guardian - Sun, 2016-04-17 01:00

After a day in which Britain generated more power from the sun than from coal for the first time, the industry should be rejoicing. But the mood is fearful

Given that the government is determined to avoid playing a financial role in the planned new nuclear plant at Hinkley Point, it is perhaps surprising that it is involved in the UK’s largest solar array.

The 70-megawatt Lyneham photovoltaic farm – big enough to provide light and heat to 20,000 homes – is located at a former RAF base in Wiltshire owned and rented out by the Ministry of Defence.

March temperature smashes 100-year global record

The Guardian - Sat, 2016-04-16 01:33

Average global temperature was 1.07C hotter - beating last month’s previous record increase

The global temperature in March has shattered a century-long record and by the greatest margin yet seen for any month.

February was far above the long-term average globally, driven largely by climate change, and was described by scientists as a “shocker” and signalling “a kind of climate emergency”. But data released by the Japan Meteorological Agency (JMA) shows that March was even hotter.

Climate change: website reveals which homes will be swamped by rising sea levels

The Guardian - Fri, 2016-04-15 06:53

Coastal Risk Australia combines Google Maps with detailed tide and elevation data, as well as future sea level rise projections

For the first time, Australians can see on a map how rising sea levels will affect their house just by typing their address into a website. And they’ll soon be able to get an estimate of how much climate change will affect their property prices and insurance premiums, too.

Launched on Friday, the website Coastal Risk Australia takes Google Maps and combines it with detailed tide and elevation data, as well as future sea level rise projections, allowing users to see whether their house or suburb will be inundated.

England's last golden eagle feared dead

The Guardian - Fri, 2016-04-15 00:50

Wildlife experts say the bird likely died of natural causes after they fail to spot him at his usual haunts in the Lake District

England’s only resident golden eagle is likely to have died after failing to appear this spring, wildlife experts fear.

The bird, which has been a resident at Riggindale near Haweswater, Cumbria, since 2001, has not seen by RSPB staff since last November, and would normally be seen at this time of year building a nest and displaying to attract a mate.

It’s settled: 90–100% of climate experts agree on human-caused global warming | Dana Nuccitelli

The Guardian - Wed, 2016-04-13 17:00

All-star team with authors of seven previous climate consensus studies collaborate to debunk the ‘no consensus’ myth once and for all

There is an overwhelming expert scientific consensus on human-caused global warming.

Authors of seven previous climate consensus studies — including Naomi Oreskes, Peter Doran, William Anderegg, Bart Verheggen, Ed Maibach, J. Stuart Carlton, John Cook, myself, and six of our colleagues — have co-authored a new paper that should settle this question once and for all. The two key conclusions from the paper are:
