Global sea temperatures accelerating

 From Prof Eliot Jacobson


In case you had any doubt, the near perfect fit of the quadratic trendline makes it clear: global sea surface temperatures are accelerating.

The current rate of warming is about 0.32°C/decade, which comes out to somewhere around 275 million Hiroshima bombs worth of ocean heating in 2025.



 

 What can governments do to reverse this trend?


  1.  Ban the sale of new pure petrol/diesel/gasoline cars immediately.   There are plenty of hybrids and EVs in production right now.  For example, in Oz, Toyota has already stopped selling the petrol-only Corolla.
  2. Give electricity utilities 5 years to get to a minimum of 60% renewables and 10 to get to 90%.  
  3. Remove all oil subsidies
  4. Tax carbon emissions, and return the tax via a monthly cheque to all residents.
What can you do?
  1. Give up meat.  This will cut your personal emissions by 1/3.
  2. Buy your electricity from a 100% green supplier (In Australia) or Green Power Options (in the US)
  3. If you can afford it, put solar panels on your roof.  
  4. If you can, replace gas or oil heating with heat pumps.  The newest heat pumps work even in sub-zero temperatures.
  5. Replace your car with an EV when your current car gives up the ghost.  Failing that, a plug-in hybrid (PHEV).  Use public transport as much as you can; fly as little as you can.
This will cut your personal emissions by 60 to 80%.

We face catastrophe.  We must act now, individually and collectively.  Before it is too late.
