The Problem is of Course the Humans II

Arctic Ice

An article posted today on Business Insider reminded me of my earlier post ten years ago referring back to the same period (the 80s) when the problem crystallised. Here we are 30 years later and little has changed. Twenty-nine years ago, James Hansen, the director of NASA’s Institute for Space Studies, told the US Senate that the question of the day – whether climate change was happening – was no longer in doubt. Hansen’s testimony before the Senate Committee on Energy

Is it so bad if the World gets a little bit hotter? You bet!

Hot Planet

Many of us share some dim apprehension that the world is flying out of control, that the centre cannot hold. Raging wildfires, once-in-1,000-year storms, and lethal heat waves have become fixtures of the evening news—and all this after the planet has warmed by less than 1 degree Celsius above pre-industrial temperatures. But here’s where it gets really scary. If humanity burns through all its fossil fuel reserves, there is the potential to warm the planet by perhaps more than 10

The Case for Geoengineering

Doctor Strange

So, you’re Caretaker of the World (that’s the Number One, the Big Boss, Head Honcho, You Know Who) and your advisers are lining up to tell you how things are out there. You listen absently … All goes well abroad, sir. However, we are concerned about the ever-increasing global population. Despite measures to curb growth (e.g. birth control), just the sheer weight of numbers itself acts as an accelerator. The population spike after the Second World War triggered this condition

How to heat a planet

Investing in Hive has significantly lowered my gas bills. And indirectly helps the economy and saves the planet at the same time. Not bad for £199.

Climate Change is already damaging the Global Economy

Geothermal Power Station

Climate change is already contributing to the deaths of nearly 400,000 people a year and costing the world more than $1.2 trillion, wiping 1.6% annually from global GDP, according to a new study. The impacts are being felt most keenly in developing countries, according to the research, where damage to agricultural production from extreme weather linked to climate change is contributing to deaths from malnutrition, poverty and their associated diseases. Air pollution caused by the use of fossil fuels is

We exceeded sustainable biomass in 1986. Now what?

I have blogged about this in the past with mentions back to a report I read in the mid-80s from the WHO. Despite trying to track this down (for my own sake more than anything), it’s very clear that we are beyond this point. In fact, this year’s Living Planet Report from the WWF states: Our global footprint now exceeds the world’s capacity to regenerate by about 30 per cent. Which means we have categorically passed the tipping point of sustainable

96 Hours to the Stone Age

Stone Age Monoliths

Originally published at GigaOm Today, we take for granted that we will have full Internet access and connectivity to the world 24/7/365 on our smartphones, tablets and notebooks. We expect to be able to check a sports score or connect with a loved one in 10 seconds or less. However, we don’t really consider that our smartphones and wireless device are connected to cell sites and cell towers, which in turn are connected to the wireless operator’s main switching facility.

It’s not about the Polar Bears anymore

Polar Bear

There is an interesting video over at Vimeo by Leo Murray in the UK that talks about environmental tipping points and the fact that we COULD be headed for a much hotter world and widespread civil war as people fight for habitable land, water and other scarce resources. The video is excellent at explaining what is happening in the environment and should be watched to gain an understanding of where we are today and how we got here. It’s one
