On 26th March 2014 the British Medical Journal published an article about the Intergovernmental Panel on Climate Change (IPCC) report on the impacts of global warming. It is hard reading, but something we all need to be aware of if we want to leave a world that is habitable for our grandchildren.
To not abuse copyright I have lifted some of their points. The whole article can be read at – http://www.bmj.com/content/348/bmj.g2351 It is well worth reading.
- “….the IPCC’s new report should leave the world in no doubt about the scale and immediacy of the threat to human survival, health, and wellbeing.”
- The IPCC believes that it is “virtually certain that human influence has warmed the global climate system…”
- The future threats of further global warming are –
– increased scarcity of food and fresh water;
– extreme weather events;
– rise in sea level;
– loss of biodiversity;
– areas becoming uninhabitable;
– mass human migration, conflict and violence.”
- “The release of just another 275 gigatonnes of carbon dioxide would probably commit us to a temperature rise of at least 2°C—an amount that could be emitted in less than eight years.”
- “Business as usual” will increase carbon dioxide concentrations from the current level of 400 parts per million (ppm)…… to 936 ppm by 2100, with a 50:50 chance that this will deliver global mean temperature rises of more than 4°C. It is now widely understood that such a rise is “incompatible with an organised global community.”
- “This is an emergency. Immediate and transformative action is needed at every level: individual, local, and national; personal, political, and financial. Countries must set aside differences and work together as a global community for the common good, and in a way that is equitable and sensitive to particular challenges of the poorest countries and most vulnerable communities.”
- “What we all do matters, not least in how it influences others.”
On a per capita basis, Australia is one of the world’s largest carbon dioxide polluters coming behind Bahrain, Bolivia, Brunei, Kuwait & Qatar. Australians have the dubious honour of producing nearly twice the OECD average for CO2 emissions & more than 4 times the world average. It is time to plant more trees & make the necessary changes to our lifestyle that supports the planet. We only have one planet & CO2 has no borders.
