The climate in 2012 and 2013

Global warming is real and is coming to a country near you. In fact it's coming everywhere and the effects will be very serious. Here's a report on some of the main points as discussed in a recent series of New Zealand radio shows. What can you do about it? Try to make more people aware of the facts.

A frosty scene in EnglandA series of ten minute slots in a New Zealand radio show provide a useful climate update. Listen to Glenn Williams discussing the climate with Gareth Renowden.

They review some of the worst weather events in 2012 including Hurricane Sandy, and look to the coming year for hints of what to expect next.

The stunning lack of official action to reduce our impact on climate also gets a mention.

We're now in a place where we must expect a severely changed planet, perhaps four or even six degrees celsius warmer than it is right now. Carbon dioxide levels are continuing to rise and are likely to top 400 ppm in 2013. The consequences involve considerable sea level rises, ocean acidification, serious ocean ecosystem damage and further loss of Arctic sea ice.

My own conclusion is that we are doing nowhere near enough to limit our carbon dioxide output at a time when the pace of change is proving to be far faster than we expected just a few years ago.

There's much more detail about all these matters at the Skeptical Science website.

Oh, and if you don't live in New Zealand don't think you don't need to listen. You do. You really, really do. We all need to listen.

Questions:

  • Is there anything you can do to help make more people aware of the facts?
  • What do you think will happen if we do nothing to reduce greenhouse gas emissions?
  • On present showing, do you think humans are looking after the Earth well?

TECHNOLOGY - The Cool Farm Tool

The Cool Farm Tool is a spreadsheet that allows farmers, growers and organisations interested in crop production to easily model greenhouse gas emissions and how they might be affected by changing production methods.

Unilever's Cool Farm ToolThe tool was originally developed for Unilever by a research team at the University of Aberdeen and is now being used on an increasing scale by individual farmers, companies buying agricultural and horticultural produce, cross company groups, researchers,  governments, and inter-governmental agencies.

The spreadsheet is published with an open source licence so it can be used, modified, and republished by anyone. It's accessible by ordinary farmers around the world and is easy to use without scientific expertise. The tool can be used to explore the effects of adjusting the methods of production to help minimise emissions.

An IPCC report in 2007, Mitigation of Climate Change provided global information, but Unilever knew they needed specific, farm or field level data if they were to make a difference. They commissioned the Cool Farm Tool as a means of obtaining this data. Much to their credit, Unilever and the University of Aberdeen decided to make the tool available for anyone to use or adapt.

There is more detail on Unilever's Growing for the Future website and in an article published by Ecosystem Marketplace.

I think this tool can really make a difference. Indeed, it must already have made a difference and will continue to do so. Well done to all concerned, especially Unilever and the University of Aberdeen. The planet needs more effort of this sort.
