Not only do extreme temperatures and severe weather make farming more difficult, climate change is also expected to decrease the nutritional value of important food crops like wheat and rice. That is a dire threat for the 821 million people who are already undernourished worldwide, and it could cause a food security crisis. (Caron Creighton)

Summer temperatures in the US will keep rising, and much of the western and central US will see a reduction of soil moisture, which exacerbates heat waves. By 2100, extreme heat days that typically happened once every 20 years are projected to occur every few years. (Reuters)

My job is to educate people and report the climate change problem. So I look at the concepts, the messages, the images and the terms, and I test them with millions of people. I'd like to tell you what I'm learning. For so many people, climate change seems abstract, distant, too big to imagine. The words we often use to describe it -- emissions, CO2, methane, net zero, anthropogenic -- are, simply put, confusing. Not that many people wake up in the morning and say, "It's a great day for some decarbonisation." These words become obstacles rather than gateways to understanding, let alone caring. The notion of carbon neutrality is also being raised by the domestic central government. New energy vehicles are being promoted. But one of the critical problem is that we still haven't managed to keep our carbon emissions at a desirable low-level.（KK）
