Climate change is literally the hottest topic in the news these days, and as news keep rolling out from publishers, nature has its way. Bumblebee populations are dying at an alarming rate and scientists still don’t know why it is happening. Pesticides and other chemicals used by human hands to grow the earth’s fruits are bringing the worst consequences to ecosystems.
Climate change is slowly killing off the bees, as weather is on a constant modifying pace. Rising temperatures push the pollinators out of the fertile regions and remain stuck in arid areas, being incapable of moving to cooler zones.
Most of bumblebee species across Europe and North America are deeply affected by global warming. The changes in weather keep pollinators from spreading and measures must be taken urgently to change the situation.
Previous studies performed on small scales have shown that species tend to migrate to the North Pole as the weather changes. A more recent and developed research points out that bumblebee species are not relocating, but rather resisting in front of the poor living resources.
The research performed by a group of scientists from Ottawa University is the most advanced analysis of the impact of climate change on critical pollinators.
The numbers are decreasing rapidly and the landmark of human intervention on climate factors shows the worst consequences. North America is deeply affected and now Europe seems to feel the effects when it comes to the bumblebees communities.
One of the reasons why bumblebees remain stuck in non-fertile areas might be the fact that fields of flowers in other zones might not be large enough. Bumblebees need wide flowery fields from early spring to late fall, to get on with life and manage their communities with food and support.
Apart from the obvious consequences climate change brings to bumblebees communities, losing pollinators is a sign that humans are playing dangerously with life support systems that we cannot do without.
Apart from the official measures expected from the UN, we must be aware that nature does not stop to modify its inner workings. The new information that reveals how bumblebee populations are shrinking is a small piece of news for affected areas but a giant alarm signal on the effects of climate change, making entire bio systems disappear.
