Solar energy to produce hydrocarbons from climate change pollutants

solar generation of biofuels

Recent breakthroughs in semiconductor physics have produced the possibility of using solar energy (photovoltaic generation) to capture CO2 (carbon dioxide) from the atmosphere, but, most importantly, to do so where it is being produced by industrial use of carbon based fuels which currently contribute to climate change pollution.

Using DC electricity to electrolyse water into Hydrogen and Oxygen is simple, but the concentration of CO2 in the atmosphere is so low, compared to Oxygen and Nitrogen, that immediately converting the hydrogen to hydrocarbons is either difficult, expensive/energy wasting (blowing a vast amount of atmosphere into the process), or both.

The new science proposes performing the capture of CO2 where it is most abundant, and consequently doing most harm to the atmosphere.

This new method uses a combination of physics and biology to produce formic acid, which is much safer to handle than hydrogen because it is a liquid and less flammable.

Adapting to #climatechange means adapting to #Trump – here's how climate change Guardian

Climate sceptics deride talk of global warming for privileging abstract future concerns over issues that matter today.

This is partly because scientific analysis has used models and forecasts to predict future impacts. Yet natural disasters and other effects of climate change are already eroding 1.6% from global GDP, leading to the involuntary migration of millions of people and exacerbating the risk of conflict and national security threats.

These issues are likelier to strike a chord with Trump than scientifically sound projections and predictions.

There is an urgent need to maintain the positive momentum on battling climate change. A politically astute approach by the resilience movement can help to achieve that.

#climatechange Ordnance Survey International helps the UAE manage Climate Change

“In Great Britain, we see how Ordnance Survey’s single source of accurate rich data drives innovation and collaboration, providing the platform, locally and nationally, on which to plan, build and maintain.

Great Britain and the UAE have a long-standing friendship, and it’s an honour for us to share our experience and expertise with the UAE, its government, businesses and people.”

Peter Hedlund, Managing Director of Ordnance Survey International, explains: “The conservation of natural resources is a global concern, geospatial data often reveals the simplest answers to many of the world’s most complex questions.

In the UAE natural resources, rising population, high energy demands and Climate Change are very real challenges.

The UAE’s Ministry of Climate Change and Environment requires this reliable up-to-date geospatial information to support the development and implementation of plans to protect the environment and manage water resources.”

#urban air #pollution around the world today - live reporting

China: A scary fact: Smog/haze is now so thick that most Chinese refer to it as 'the weather'. They are often unaware it is not a natural phenomenon.

Sydney Australia: “My son is three and has bad asthma, so I’m very aware of air quality. When we had those dust storms, that was really bad.
We were warned over the weekend that the air quality wasn’t going to be very good, so we paid attention and kept him indoors.”

The Air We Breathe: Today, Guardian Cities kicks off a week to exploring one of the worst preventable causes of death around the world: air pollution.

Dirty air kills 3.3 million people every year – more than HIV, malaria and influenza combined. Indoor pollution claims roughly the same number again.

Most of these deaths happen in cities, where automobile exhaust, factories and power plants, and coal and wood fires for heating and cooking are among the deadliest culprits.

India: Hello from Delhi, the capital of India, and one-time “most polluted city in the world”.

As we’ve already reported, that unenviable title now belongs to Onitsha, a tropical port city in Nigeria – but Indians aren’t celebrating yet.

According to the WHO, half of the world’s 20 most-polluted cities are in India, starting with Gwalior in Madhya Pradesh, and Allahabad in Uttar Pradesh.

The rankings have helped to drive a growing awareness in India that air pollution is not confined to its smoggy capital.

The proliferation of coal-fired power stations, brick kilns, crop burning and other pollution sources across northern India have made it so not a single city in the entire region meets international air quality standards, according to a report from Greenpeace.

Delhi is where the problem gets most attention though, and pictures of the haze that settled on the city after Diwali in November last year were broadcast around the world.

The city government labelled the toxic air an “emergency” and ordered immediate action, including temporarily closing schools and construction sites. It helped clear the immediate spike in pollution, but longer-term steps are still urgently needed.

#biodiversity What does boycotting #palmoil achieve?

Guardian live chat:

In response to concerns about the impact of palm oil production on biodiversity, local communities and plantation workers, some individuals and campaign groups have called for a boycott of any products containing the commodity.

Others point out that some of the alternatives to palm oil such as soybean or rapeseed oil come with their own list of problems.

Others still argue that consumer boycotts in Europe and the US are futile when countries such as India and China – two of the world’s largest palm oil importers – leave palm oil’s sustainability credentials largely unquestioned.

Join us on Wednesday 5 April between 1-2pm (BST) as we debate the role of consumer boycotts and where they fit in to the sustainable palm oil debate. Questions we’ll be asking include:

What role can boycotting play in creating a more sustainable palm oil industry?
Beyond boycotts, how can consumers improve the sustainability of palm oil?
How can companies engage with the concerns of their customers?
What are companies doing about deforestation, biodiversity loss and treatment of workers in the palm oil supply chain?
