The change
What do you think about the climatic change?&nbsp;

People think my hometown is in the north of China. So they think it's unnecessary to us. Actually, the temperature is low in my hometown in winter.

@Dan Smith- cannot agree more.Also it is sad that&nbsp;&nbsp;<span style="font: 14px/24px arial, 宋体, sans-serif; color: rgb(51, 51, 51); text-transform: none; text-indent: 28px; letter-spacing: normal; word-spacing: 0px; float: none; display: inline !important; white-space: normal; background-color: rgb(255, 255, 255); -webkit-text-stroke-width: 0px;">The United Nations Climate Change conference seems to make baby progress only.

@Dan Smith - that's probably the most controversial thing I've ever seen you write. Welcome to the dark side.

I'm really sad that spring and autumn are getting shorter.

I think humankind is probably going to "muddle though" and survive.I think climate change is going to have huge geopolitical consequences. It isn't going to be as simple as "temperate zones shift toward the poles." It isn't just chilly climates getting more comfortable. Overall the disturbance in ecology will be difficult to adapt to--and mostly bad. I suspect world population is near its peak and will be lower in 100 years than it is today.&nbsp;
