Not a student currently, but I'd guess CH4 + O2 = H2O + CO2, which is methane combustion. Let's see, to balance, well, we've got three oxygen on the right side, two on the left, so at a minimum we need to increase to 2O2... So where did that leave it? 4 hydrogen versus two, so 2H2O... Now that is four oxygen on the left, four on the right, yep all equal.

So, CH4 + 2O2 = 2H2O + CO2 is the balance. And I'd guess the climate relevance would be something to do with the use of natural gas for heating or energy production.

Sharing instead of commenting because while it was mildly interesting to exercise long disused skills, commenting would put the answer right below the question and short circuit actual students from trying it.
OK science students, which molecules are represented here, what is the importance of this chemical reaction to earth science, and how should it be balanced?

USLaunchReport has pretty good footage of the SpaceX static test fire anomaly this morning. You can actually see the faring come down and crash hard.

Incident happens right at 1:11 in the video, at 1:19 the faring tilts down and falls, impacts at 1:24 and clearly explodes. There is a short series of continued bursts, and a flash of light at 2:04. Up to about 2:07 it looks like after the first fireball, flames are largely confined to the left of the tower, but then black smoke starts rising from the right of it as well, and at 2:49 flame becomes visible. At 3:33 there is a timeskip. There is another large explosion at 3:43 (though due to the timeskip it is not clear how long this was after the primary event) and again at 3:55. Helicopter audibly arrives at 4:14.

Thankfully, no injuries have been reported.

Do you see what I see? And no, I don't mean a star, a star.
