interest centres on a different gas: free oxygen (O2) spawned by early biological production. The initial increase of O2in the atmosphere, its delayed build-up in the ocean, its increase to near-modern
Atmospheric and climate scientists call the planet's carbon dioxide rise since the first Earth Day unparalleled in at least 800,000 years.

While preparing to teach an intro course on climate, I'm reminded of why we use the term climate change and not global warming. Yes, the Earth is warming from a thickening layer of greenhouse gases in the atmosphere caused by us. But climate changes range from sea level rise to ...
Rise of the Robots The word “robot” was coined in 1920 by the Czech playwright Karel Capek. 1 For most of their history, however, robots have been dumb, inelegant mechanical devices sitting out of sight in factories. Things are starting to change, however. 2 They brought cheap cameras...
The greenhouse gas emissions may cause the ozone layer to destroy, the ozone layer is Earth's protective umbrella, did not have its consequence to be very serious.The greenhouse gas emissions causes the atmosphere to change warm, causes two levels of glaciers to melt, then sea level rise, su...
This is when small amounts of gases in the atmosphere, like carbon dioxide, methane and water vapour, trap heat from the sun and therefore warm the earth. Without the 'greenhouse effect', the earth would be about thirty-three degrees Celsius cooler than it is. So, we need those gases. ...
We can depend on hisTRUSTWORTHINESS–even in the midst of trouble (Psalm 9:9-10). God will not permit any troubles to come upon us, unless he has a specific plan by which great blessing can come out of the difficulty. –Peter Marshall ...
Because of the pollution, the earth has been completely destroyed, from top to bottom. The atmosphere* has no oxygen* and moisture*. As a result, the plants are burned by the strong sunlight with a great number of harmful rays. Of course, none of them are still alive. Not only no ...
