Could you please link to the source for your claim?
In 2018, the UN Food and Agricultural Organization reported that climate change is one of the leading drivers of global hunger [1].
"Overall, the number of hungry people grew for the third year in row in 2017, reaching a total of 821 million worldwide. The paper warns that this number will continue to rise if countries fail to tackle climate change and to build resilience to its unavoidable impacts."
And just this summer, Madagascar made the news for suffering the world's first climate-induced famine [2].
This is true - hunger rates are rising since about 2015, but the link to climate change isn't singular. War is very influential, and the leading spots where you see hunger - Somalia, Yemen, Iraq, Sudan, Nigeria, Syria are known for their situations separate from climate change.
It's also unclear if this is a noise figure rather than a trend. Overall hunger has been declining for decades. Less people die from hunger and weather than ever before if you move the running average out a bit (10 years for example)
I wouldn't discount climate change here. It's obviously part of it. Syria is a prime example, where drought has contributed to the civil war. But like all climate change - it's nuanced.
Some specific sourcing would really help me accept these claims.
What I'm taking away here is that climate change is both directly driving hunger, and compounding other drivers like war. You call it "nuanced," which of course is true, in the same way that the proximate cause of death "from old age" is nuanced: each thing that goes bad compounds all the other things. I feel that misses the point, which is that climate change is only just beginning to exacerbate global hunger.
That omits the second half of the trend analysis by Our World In Data. The decades-long drop in global hunger has in fact reversed in recent years, and it's misleading just to cite the preceding decades of progress without any mention of its recent reversal:
However, over the last few years, the total number increased to around 663 million in 2017. This increase in hunger levels are largely a result of increases in Sub-Saharan Africa (where rates have risen by several percentage points in recent years) and small increases in the Middle East & North Africa. The UN FAO have linked this increase in undernourishment in particular to the rising extent of conflict-affected countries (which is often a leading cause of famine), and compounded by climate-related factors such as the El Niño phenomenon (which can inflict both drought and flood conditions).
Total numbers may have increased, but proportional numbers are still down. In 1990, 25% of the world lived in hunger, today it's under 10%. The overall decline is unambiguous.
