Normally, you will split the block in half, then each half will be split again, until the pieces are about 6 to 8 inches (15 to 20 cm) at the largest cross section. 1  Stack split wood so that air can circulate around it to allow it to season thoroughly before it is burned in a wood stove or fireplace.
Why does CO2 get most of the attention when there are so many other heat-trapping gases (greenhouse gases)? Global warming is primarily a problem of too much carbon dioxide in the atmosphere. This carbon overload is caused mainly when we burn fossil fuels like coal, oil and gas or cut down and burn forests. There are many heat-trapping gases (from methane to water vapor), but CO2 puts us at the greatest risk of irreversible changes if it continues to accumulate unabated in the atmosphere. There are two key reasons why.
As you can see from the graphs, the amount of carbon dioxide in the atmosphere has increased steadily over the past 150 years, and so has the average global temperature. Some of this is due to human activity. Along with other gases such as methane and water vapour, carbon dioxide is a greenhouse gas. It absorbs heat energy and prevents it escaping from the Earthâs surface into space. The greater the amount of carbon dioxide in the atmosphere, the more heat energy is absorbed and the hotter the Earth becomes.
