New Zealand Energy Security And Climate Change
This paper sets out the case for taking early and effective action to improve New Zealand’s energy security, and doing so in a manner which minimises New Zealand’s future greenhouse gas emissions

Climate Change Mitigation – Rapid Change Needed To Restrict Global Warming To Below 2°C
The world’s climate is changing, but it remains possible to slow down the speed and extent of change if all countries, including New Zealand, play their part. Rapidly deploying the many different types of mitigation technologies and available measures and developing effective policies to reduce greenhouse gas (GHG) emissions can also produce many additional benefits that offset their overall cost.
Read MoreThe Carbon Cycle – Towards Becoming Carbon Neutral
Early chemists believed that organic compounds were fundamentally different because they contained a vital force that was only found in living systems. In fact, the common elements in all organic compounds are hydrogen and carbon.
Read MoreEthical Issues and Climate Change
Human–induced climate change is widely regarded as one of the greatest – if not the greatest – moral challenges of the 21st century. Not merely does it raise numerous ethical issues, but many of these are profoundly difficult and take us to the limits of our moral imagination. Moreover, the ethical dilemmas posed by climate change arise at multiple levels – for citizens, scientists, policymakers, organisations, companies, nation-states, and the international community – and traverse many different areas of moral inquiry.

Ocean Acidification – The Other CO2 Problem
Ocean acidification (OA) has been described as “global warming’s evil twin” and is considered by many scientists to be one of the greatest environmental challenges to marine organisms in the 21st century. Long-term records have shown a decrease in average ocean pH of 0.1 units since the beginning of the industrial age (from 8.21 to 8.10), and pH is expected to decrease a further 0.3 to 0.4 units by 2100, resulting in seawater that contains 150% more H+ than present.
Read MoreThe Importance Of Methane
Concern about the emissions of Greenhouse Gas (GHG) that causes Climate Change focuses primarily on carbon dioxide (CO2), which is an unavoidable consequence of burning fossil fuels. However, methane (CH4) is an increasingly important contributor to Climate Change.
Read MoreClimate Change – A Psychological Challenge
Climate change is a hard problem. To accept that the climate is being affected by human practices and that it is our collective responsibility to take action, we have to get our heads around a series of mental obstacles put in place by our evolutionary history and cultural practices. What are these, and what can we do about them?
Read MoreClimate Change – Living in a Warmer World
Planet Earth has experienced large shifts in climate over time. In the depths of the last Ice Age, around 20,000 years ago, average temperatures were about 5°C lower than they are today. It looks now as though global warming is likely to heat up the world between 2 and 6°C by the year 2100.
