The amount of CO2 is increasing all the time – we just passed a landmark 400 parts per million concentration of atmospheric CO2, up from around 280ppm before the industrial revolution. That’s a 42.8% increase. A tiny amount of CO2 and other greenhouse gases, like methane and water vapor, keep the Earth’s surface 30°Celsius (54°F) warmer than it would be […]

New South Wales and southern Queensland are going to be suffering from warmer weather and less rain than in the past. This temperature change is called “sudden stratospheric warming.” It happens when the air above the South Pole starts to warm up rapidly. Predictions are that the warming of Antarctic will likely be higher than a previous record high in […]
