Doesn’t everyone want to stop global heating? Perhaps not!
Here I suggest that there is an ‘elephant in the climate’ that no-one discusses: those many people who live at high latitudes, largely in the wealthy, influential global north, who experience really cold winters and who are welcoming a degree or two of global heating.
How can we overcome this obstacle to developing a global consensus? One that accepts that messing with the Earth’s thermostat is a really scary thing to do!
Read MoreWhy would an ordinary scientist blog about billionaires? I claim relevance because I reckon that the world would be a lot better off if we valued careful investments of society’s hard-won wealth on behalf of all citizens and life on this planet more that feathering the nests of a tiny fraction of humanity who use their extreme wealth to pursue their own agendas.

Read MoreHaving created such a valuable national resource 96 years ago, surely it is time that our nation recognises that CSIRO’s strategic research for industry and the public good is of vital ongoing importance to the nation and should be funded accordingly.

Read MoreIt is not a question of tilting at windmills! If the blades of a wind turbine absorb some of the wind’s energy, allowing us humans to warm our spa baths, won’t that wind now contain less energy?

Why is it that most humans take their food for granted?
Throughout history, societies have behaved as if our food supply will last forever - until it doesn’t!
I argue here that it is perilous for us to have a ‘Magic Puddin’ view of food - and of the agriculture, farming and our precious soils which produce it.
Read MoreGrazing management means that the farmer chooses how much and the quality of the diet a grazing animal is offered as they are moved from paddock to paddock over time.
If it is done well - taking into account issues of the climate, grazing animal, pasture, soil and profitability - it can result in good animal and pasture outcomes.
However - if it is done poorly - such as when systems are not flexible, it can reduce the animal’s choice of diet which can have a flow-on effect of lower animal production.
Unfortunately, there are no simple recipes for success that are widely applicable.
