Sounds to me like some testimonial by someone who believes in God. Or ghosts. Or UFOs.

Climate can change and has changed and will change in to future.
And the Ukraine was and still is a breadbasket of the world, and climate wasn't it's biggest obstacle :

"The Ukrainian national idea persevered during the inter-war years, and Ukrainian culture even enjoyed a revival due to Bolshevik concessions in the early Soviet years. By the late 1920s, however, the Soviet reaction was severe, particularly under Stalin.

To satisfy the state's need for increased food supplies and finance industrialization, Stalin instituted a program of collectivization of agriculture, which profoundly affected Ukraine, breadbasket of the USSR. In the late 1920s and early '30s the state compounded the peasants' lands and animals into collective farms. Starting in 1929 a policy of enforcement was applied, using regular troops and secret police to confiscate lands and material where necessary.
...
Forced collectivization had a devastating effect on agricultural productivity. Despite this, in 1932 Stalin increased Ukraine's production quotas by 44%, ensuring that they could not be met. Soviet law required that the members of a collective farm would receive no grain until government quotas were satisfied. The authorities in many instances exacted such high levels of procurement from collective farms that starvation became widespread. At least four million starved to death in a famine, called the Holodomor in Ukrainian.

The Soviet Union suppressed information about the famine, and as late as the 1980s admitted only that there was some hardship because of kulak sabotage and bad weather. Today, its existence is accepted. Some historians consider the famine of 1932–33 to be the necessary consequence of Stalin's program of industrialization and collectivization. Others maintain that the famine was an avoidable, deliberate act of genocide."

"Despite claims that the country is about to return to the glory days of the nineteenth century, when it fed half of Europe, not everyone is convinced that Ukraine’s agricultural wealth is being well-managed. According to Sergey Feofilov, director of Kyiv-based agriculture consultancy Ukragroconsult, the nation’s grain industry is still far from realising its production and export potential. “This year’s bumper crop is more the result of good fortune than industry development,” Feofilov said."
