Welcome

The world is changing faster and faster.

At this time, the short election cycles (3 years in Australia and 5 years in USA) has grown a generation of political leaders who think short term and think for each election cycle.

However, humanity is facing a real challenge.

Oil is a finite resource. The price of oil will increase as the production becomes more difficult and expensive. With current large scale farming closely linked to oil-based fertilizers, food price will also increase. I have no crystal ball and have no idea when this will happen.

Science is clear that CO₂ is a greenhouse gas. The higher is the concentration of CO₂ in the atmosphere, the larger is the greenhouse effect. With the shift of the energy balance, Earth will warm up. Human has only 5,000 years of written history. During all these years, we have never had CO₂ level as high as today.

Higher global temperature means more ice will melt leading to rising sea level. Most large cities are built near the coast, at almost the current sea level. As sea level rises, the cost of moving these cities will be astronomical. Many poor countries are in low lying areas. Movement of these displaced people will become a major source of problem/conflicts.

Although governments have agreed to limit the rise of global temperature to 2^oC, the target has already become unachievable. There is already 0.9^oC since the industrial era. There is another 1.6^oC coming no matter what we do.

As the climate is moving towards a new equilibrium, weather is going to fluctuation violently. Heat records and cold records have been broken in the last 10 years almost routinely. Huge storms are more frequent than normal.

The short election cycle means that politicians are not going to solve the problem with long term view. What can an average citizen like me can do?
