The latest report from the International Panel on Climate Change (IPCC) was another massive effort. It is based on over 6,000 scientific studies and involved a team of 90 scientists and policy experts nominated from 40 countries. The process started in March 2017 and there were three report drafts and 42,000 reviewer comments. The final report was published on 8 October 2018 after a week-long meeting in South Korea. See the following links for the conclusions and implications.
In December, the world’s governments will review the implementation of the Paris Agreement to tackle climate change at a conference in Katowice, Poland.

And how you can help: Five top tips to combat climate change
An international team of scientists has shown that even if the carbon emission reductions called for in the Paris Agreement are met, there is a risk of our planet entering what the scientists call “Hothouse Earth” conditions.
This would see the climate stabilise in the long term at a global average of 4-5°C higher than pre-industrial temperatures, with the sea level 10-60 m higher than today.
The scientists conclude it is now urgent to greatly accelerate the transition towards an emission-free world economy. Avoiding a “Hothouse Earth” requires not only reduction of carbon dioxide and other greenhouse gas emissions but also enhancement and/or creation of new biological carbon stores.

The Sky’s Limit is a new study by Oil Change International which reveals the need to stop all new fossil fuel infrastructure and industry expansion. It focuses on the potential carbon emissions from developed reserves – where the wells are already drilled, the pits dug, and the pipelines, processing facilities, railways, and export terminals constructed.
Key findings are:
- The potential carbon emissions from the oil, gas, and coal in the world’s currently operating fields and mines would take us beyond 2°C of warming.
- The reserves in currently operating oil and gas fields alone, even with no coal, would take the world beyond 1.5°C.
- With the necessary decline in production over the coming decades to meet climate goals, clean energy can be scaled up at a corresponding pace, expanding the total number of energy jobs.
- No new fossil fuel extraction or transportation infrastructure should be built, and governments should grant no new permits for them.
- Some fields and mines – primarily in rich countries – should be closed before fully exploiting their resources, and financial support should be provided for non-carbon development in poorer countries.
- This does not mean stopping the use of all fossil fuels overnight. Governments and companies should conduct a managed decline of the fossil fuel industry and ensure a just transition for the workers and communities that depend on it.
The United Nations Climate Change Summit in Paris, held from 30 Nov – 12 Dec 2015, has reached a new universal agreement to tackle climate change. This is great news but there will still be much to do to put it into action and to ensure what has been agreed is enough. The sooner we stop using dirty fossil fuels and the quicker we switch to clean renewables the better.
The new agreement aims to limit global warming to “well below 2°C” and to aim for no more than 1.5°C. Already the increase is 1°C and current plans, at best, will limit the rise to 2.7°C. So the agreement includes a pathway for continued review, which will require ever more demanding action over coming decades.
Backed by 196 countries, the UN Framework Convention on Climate Change (UNFCCC) has near universal world membership and aims “to stabilise greenhouse gas concentrations in the atmosphere at a level that will prevent dangerous human interference with the climate system”.
