The recent documentary ‘What the Green Movement got Wrong’ by Stewart Brand was a welcome change of focus and many thought it would address the clouding of the climate issue and the problems with its framing within the media. However it appeared one sided focusing on nuclear power and GM foods and how if environmentalists hadn’t campaigned against them at the time the world would be a better place.
This short article quickly shows the counter points and corrects some of the more sensational statements made. If you haven’t seen it yet watch it here.
Opposition to GM foods caused starving in Africa
The report blamed environmentalists for starvation in Africa and energy scarcity throughout the world. “That blame is misplaced. Of all those at fault for drought and food shortage in Zambia, environmentalists rank low on the list”, Adam Werbach, former Sierra Club President. War, corruption and disease are far greater to blame and those needing to blame someone for these should focus on the bigger issues affecting the African nations. Continue reading
The UK is set for some stormy weather over the next few days. As one low pressure system moves away we will be afforded a day or so of relatively calm weather before a deep depression hits bringing with it high wind speeds and heavy rain.
Response to Channel 4’s recent documentary ‘What the Green Movement Got Wrong’
South-East Asia was recently the victim of yet another natural disaster in the form of a tsunami that has so far claimed the lives of at least 435 with another 100 thought to be missing.
More than 23,000 people have been displaced by the tsunami in a region where in the shadow of Mt Merapi, central Java, people are only just returning to their villages to check if homes and farms are still there following volcanic activity that killed 36 people last week.
Many homes were destroyed by waves after the 7.7 magnitude quake, which struck 20km (13 miles) under the ocean floor near the Mentawai islands. Ten villages on the islands were completely swept away by the tsunami reported to have been between3-6 metres high.
The Intergovernmental Panel on Climate Change (IPCC) is the single most important organisation for the assessment of climate change but who are they and what do they actually do?
The IPCC is a body established by the United Nations Environment Programme (UNEP) and the World Meteorological Organization (WMO) to “provide the world with a clear scientific view on the current state of climate change and its potential environmental and socio-economic consequences”. Simple?
What they do is bring together experts in every single imaginable area of earth sciences and ask the question is the climate changing and if so what happens if it continues. Continue reading
Wind is all around us but what is it and what actually causes it? Here we examine one of the simplest aspects of weather and some of the terminology that surrounds it.
Wind simply is the movement of air. And the air moves because of differences in temperature and pressure around the globe.
This difference in temperature and pressure is because at the equator (the hottest area on earth) the hot air rises before cooling and sinking as it moves towards the poles. This leads to the basic concept of atmospheric circulation… the three-cell model (see right).
As the air cools it shrinks and as it heats it expands. This is the basis of air pressure, with high pressure essentially pushing down harder on the Earth’s surface because there is more air present it is just more dense.
