Climate change causes spring to start sooner, what could see food prices increase and insect populations decrease

Researchers are afraid that climate shift could have more dangerous effects for farming and other industries in the natural world.

In UK scientists made 50-year study, facing that climate change leads to spring arrive earlier in the UK, causing disruption to natural life cycles which could make food more expensive.

The study of the seasonal habits of more than 250 species found that aphids, moths, butterflies and birds are laying eggs up to a month earlier than they did in the mid-20th century.

In the north, butterflies become active earlier in the warmer, wetter west than the colder, drier east, but the team documented the opposite for birds laying eggs.

Many plants and animals use temperature to time breeding and migration, which are both associated with the onset of spring.

The disruption to these natural cycles could threaten the survival of some animals by putting them “out of sync” with the appearance of their prey, the research concluded.

After data analysis that stretches back to 1960, it predicted we may see the number of insects plummet as they cannot feed on the plants they need to sustain them.

In addition, it could damage the production of food by making certain crops more vulnerable to pests and the final crop more expensive for consumers.

Lead author Dr James Bell, told The Independent: “Due to the wet spring, farmers are not able to move their heavy machinery on to waterlogged fields to plant potatoes, so they are planting later. 

“However, the aphids are arriving earlier and feeding on plants that are not yet mature. This, in turn, can affect the harvest because young plants cannot withstand the threat. A smaller harvest will drive up the prices of potatoes.”

The findings, published in the journal Global Change Biology, showed the shift towards an earlier spring was happening in shady forests as well as more open areas.

Dr Bell added: “There was already good evidence that spring is coming earlier each year, but what we didn’t expect to find was that it was advancing as much in forests as it is in open areas such as grassland.

“Equally, in areas where we’d expect to see much greater acceleration, such as urban parkland, the rates of advance appear to be the same.

“This all points to a complex picture emerging under climate change, which makes ecosystem responses hard to predict, and even harder for conservationists to prepare for.

This research is important because is shows that people cannot rely on habitat to slow down climate change impacts, even in woodlands and forests where the conditions are more stable, and which were expected to buffer against adverse changes. More must be done to save nature.
