What Is the Carbon Limit ??? : That Depends Who You Ask


Scientists are offering widely varying estimates of how much carbon we can emit into the atmosphere without causing dangerous climate change. But establishing a so-called carbon budget is critical if we are to keep the planet a safe place to live in the coming century.

How much carbon can we safely emit into the atmosphere without the planet suffering dangerous climate change? 

It would be good to know. 

The world’s governments have agreed that “dangerous” should mean any warming above two degrees Celsius.

 And in recent reports, the Intergovernmental Panel on Climate Change (IPCC) has tried to translate that into a future carbon budget.

But too many different numbers are still floating around. We could have more than 500 billion tons of carbon that we could safely emit, or the real 
figure might be close to 100 billion tons — it depends on whose estimates you decide to accept.

The science is a work in progress, but we know how to make judgments on what it…


The other side of Rainforest Alliance – Exposing Green Capitalism.

The other side of Rainforest Alliance – Exposing Green Capitalism.

Supermarket shelves are filled with the ever more popular and lucrative “Ethical Green Products.” A quick visit to Tesco, Marks and Spencer, Waitrose, Sainsburys etc. will show you this. The modern shopper likes to feel that he is buying something that doesn’t damage the environment and the various organisations that have created Green Logos trade in this “feel good” factor.

Green means business and groups like Rainforest Alliance know it only too well.

This organisation, initially and activist group, has decided to work “with the capitalists” rather than against them believing that by being nice to them they will gradually change things from within.

With this idea over the recent years they have initiated a series of projects in different parts of the world. One of the products with which they are working most is coffee, one of the most important and …

INFORMATION OVERLOAD : Why Solving The Last Mile Problem In Data Analytics Will Start A Revolution

Ron Bodkin , Teradata

To understand the role of open source in data analytics, it is helpful to think back to a concept from telecommunications: the last mile. The last mile is the distance from the distribution points of telecom and cable operators to the house and it was always seen as a bottleneck.

But there was good reason for that bottleneck. About 95% or more of all of the wiring in the system was in the last mile.

Something similar is happening in the world of open source data analytics. 

Hadoop is rightly celebrated as a game changer, but people forget about the “last mile”: the process of converting that power into something that most people can use. 

In my view, the revolution in big data will come from solving the “last mile” problem, that is, making big data useful for the masses.

Business and technology executives who are building data analytics capabilities to take advantage of big data can avoid many problems by understanding the relationship between open source and the last …

A crime scene in San Pedro Sula, murder capital of the world

Of the world's 50 most dangerous cities, 43 are located in Latin America and the Caribbean. InSight Crime looks at some of the factors driving the violence.

Business Insider revived the list in a recent publication, based on a report from the Mexican Citizens' Council for Public Security and Criminal Justice that came out earlier this year, ranking cities around the world by their homicide rates. With the exception of Cape Town, South Africa, the 20 most violent cities are in Latin America and the Caribbean.

Of the 50 urban areas with the highest homicide rates, 16 are located in Brazil, nine inMexico, six in Colombia, and five in Venezuela (see map below). San Pedro Sula inHonduras was ranked as the most violent city in the world for the third consecutive year, followed by Caracas, Venezuela and Acapul…
