Richard Lindzen misrepresents climate data at House of Commons

Richard Lindzen is an American atmospheric physicist at MIT (Massachusetts Institute of Technology) known for his work in the dynamics of the middle atmosphere, atmospheric tides and ozone photochemistry. He was a lead author of Chapter 7, ‘Physical Climate Processes and Feedbacks,’ of the IPCC Third Assessment Report on climate change. He is sceptical about some of the more alarming predictions about climate change and concerned about political pressures on

Artificial leaf could generate fuel by photosynthesis

Scientists at the University of Glasgow have created an artificial ‘leaf’ capable of converting the sun’s energy to liquid fuel. Professor Richard Cogdell from the University of Glasgow explained “The sun gives its energy away for free but making use of it is tricky. We can use solar panels to make electricity but it’s intermittent and difficult to store. What we are trying to do is take the energy from the

Global Temperature trend

Despite the freezing (for the UK anyway) start to the year, NASA have confirmed that global average surface temperature in 2011 was the ninth warmest since 1880. The finding continues a trend in which nine of the 10 warmest years in the modern meteorological record have occurred since the year 2000. NASA’s Goddard Institute for Space Studies (GISS) in New York monitors global surface temperatures have released an updated analysis

fracking diagram

Fracking is the process of extracting natural gas trapped in hard shale rock by drilling into it and creating small explosions to release the gas. Water, sand and chemicals are injected into the rock at high pressure, which allows the gas to be released, captured and stored above ground. It is shorthand for hydraulic fracturing and refers to how the rock is fractured apart by the high pressure mixture. Although

Solar-panel-area-to-supply-the-world

It’s a calculation that can be done on the back of an envelope. Gerhard Knies a German particle physicist was the first to estimate how much was required to meet humanity’s demand for electricity. In 1986, in direct response to the Chernobyl nuclear accident, he scribbled down some figures and arrived at the following remarkable conclusion: in just six hours, the world’s deserts receive more energy from the sun than

Climate change sceptic admits temperature data shows warming

Richard Muller of Lawrence Berkeley National Laboratory in California has gained a solid scientific reputation for his work in astrophysics and particle physics. He also has a reputation for not being afraid of wading into public policy debate. Although not a climate scientist, Muller has published peer reviewed papers that questioned elements of historical temperature data of climate change and is therefore considered a ‘credible’ sceptic. An expert team was

China bans incandescent light bulbs

Those who think China’s supposed intransigence over environmental issues is an excuse for doing nothing must now rethink their position as China has pledged to replace the billion incandescent light bulbs it uses annually with more energy efficient models within five years. The move is part of efforts to improve lighting efficiency and reduce greenhouse gas emissions and follows in the footsteps of Australia, the EU, Brazil and others. In

Solar feed-in-tariff cut

The UK government has announced a 50% cut in the subsidy for the Feed-in-Tarriff scheme where UK householders receive a premium price for any excess electricity generated from their solar panels. The scheme has been very popular, encouraging many householders with savings to invest in solar power for considerably better returns than a high interest savings account (41p a kWH, around 4 times the normal electricity price). Even those without
