I have come to regard November as the older, harder man's October. I appreciate the early darkness and cooler temperatures. It puts my mind in a different place than October. It is a month for a quieter, slightly more subdued celebration of summer's death as winter tightens its grip.

Life is fragile: it thrives only in a narrow range of temperatures between freezing and boiling. How lucky that our planet is just the right distance from the sun: a little farther, and the death of the perpetual Antarctic winter - or worse - would prevail; a little closer, and the surface would truly fry anything that touched it.

Plate tectonics is not all havoc and destruction. The slow movement of continents and ocean floors recycles carbon dioxide dissolved in the oceans back into the atmosphere. Without this slow speed carbon cycle, Earth's temperatures would cool dozens of degrees below your comfort zone.

Where most of the country is, well, hot - from the bone-baking dry heat of the desert to the flesh-melting humidity of Kerala in the south - Kashmir is cool: so cool, in fact, that in the winter, the temperatures can sink to sub-zero.

Climate change is the greatest threat to humanity, perhaps ever. Global temperatures are rising at an unprecedented rate, causing drought and forest fires and impacting human health.

The best scientific evidence suggests temperatures are rising, and the best scientific evidence suggests man-made anthropogenic carbon emissions have some substantial thing to do with that. However, does that mean the trend will continue forever? We don't know.

The knowledge that the atoms that comprise life on earth - the atoms that make up the human body, are traceable to the crucibles that cooked light elements into heavy elements in their core under extreme temperatures and pressures. These stars- the high mass ones among them- went unstable in their later years- they collapsed and then exploded- scattering their enriched guts across the galaxy- guts made of carbon, nitrogen, oxygen, and all the fundamental ingredients of life itself. These ingredients become part of gas clouds that condense, collapse, form the next generation of solar systems- stars with orbiting planets. And those planets now have the ingredients for life itself. So that when I look up at the night sky, and I know that yes we are part of this universe, we are in this universe, but perhaps more important than both of those facts is that the universe is in us. When I reflect on that fact, I look up- many people feel small, cause their small and the universe is big. But I feel big because my atoms came from those stars.

There are a range of associated impacts related to increasing temperatures which affect both evaporation rates and river systems which are already over stressed and these will hit farming communities and the health of crop lands.
