Obama and Xi Jinping announcement: a huge step for climate action? Or a backward step?

Date Published:

Obama is currently a ‘lame duck’ president with a hostile senate, and approval rating that suggests a likely hood the next US president may well be a republican.

In Australia when the less conservative party took a position to take steps to address climate change, it became a call to arms for conseratives opposed to any action on climate change.  The conservatives moved from favouring an emssions trading scheme, to effectively opposing any real action.  Then the conservative won power and there was an unwinding of steps to address climate change.

Similarly in the US, Obama taking steps on climate change will almost certainly galvanise those in the republican party who are most doubful about human actiivy driving climate change.   In could become a key platform of the republicans to abandon the very plans announced by Obama.

Of course, the key stategy from Obama to avoid this is to allow the counter position that unwinding Obama’s targets could leave the republicans with a policy that suggests China is more sophisticated that the US.

The initiative by Obama in his current position IS dangerous because of the risk of a backlash, but with China on board it also could possibly work.  Which was will things go? Only time will tell.

Base load Solar and Wind: Renewables alone not a substitute for fossil fuels.

At least, not a direct substitute. Solar and Wind have proven to be successful partial cost-effective substitutes for fossil fuels, but fossil fuels are stored energy, and solar and wind are not. Renewables are a disruption, and disruptions are usually not one-for-one substitutions.

There are two strategies for replacing fossil fuels in the grid, and they can be used together:

  • 1: Add energy storage for when renewable energy levels fall below a threshold.
  • 2: Base load “solar and wind”: Design to provide base load at a low threshold of wind and light.

Without such strategies, it is impossible to reach the goal of removing reliance on fossil fuels. With the right strategy, it is possible to realise benefits go far beyond just replacement.

We can’t run out of fossil fuels.

In the 1970s, there were the ‘Oil Crises‘. Then, and at other times it has been suggested that one key reason for moving to renewables, is that as there is only a finite supply of fossil fuels which will come to an end one day. But when?

There is also a mistaken belief that ‘peak oil‘ projections are a result of supplies of fossil fuels becoming exhausted.

Whether you are worried oil supplies will run out, or are hoping oil supplies will run out, although prices may rise, they won’t run out. In fact, we can’t possibly use all fossil fuel.

The innocent child assumption: even Hitler?

I recently watched an episode of “Comedians in cars getting coffee”,(C6:E4 11:55) where Ricky Gervais has a photo of Hitler as a baby. And relates, “I talk about sci-fi, and I always go back and kill Hitler”. And I go, I go, they go “well people tried all the time”, and they go “No I’d go back and kill him as a baby”. I go, “You’d go back, and kill baby Hitler, who hasn’t done anything wrong yet, and just strangle him? Have you seen Hitler as a baby” and I pull out this photo and I go “He was adorable”.
