How Animals and Plants are Affected by the Greenhouse Effect

If we manage to keep global warming to 1.5 degrees, it means a radical difference to life on earth compared to if it were to be even hotter. It shows a large study of more than 100,000 species of plants, insects, and vertebrates.

A temperature increase of two degrees would cause twice as many animals – and plant species – to have very limited living space and thus risk becoming homeless.

And as the temperature rises, plants and animals are affected in different ways, making the ecosystems we have today difficult to live in.

Places that are climate-adapted for animals need not be for plants.

He believes that plants and animals are affected by heating in different ways. And most importantly, the insects are affected. The species slides geographically apart and the food thus disappears.

The picture is based on a very similar model, made at the Climate Research Center at the University of Norwich in England, of how the habitat for over 115,000 different plant and animal species looks, how their environment is affected by the warming and what ability they have to move to suitable areas.

For many species, space is shrinking so quickly that they do not keep up, but disappear. But how much nature changes depends very much on how warm it gets.

If the average temp increases by 1.5 degrees, the model says that about five percent of plants and animals lose more than half their current range.

But already at two degrees of heating, the consequences are much more serious. Then there will be more than twice as many species that lose half the surface of their current habitats. Thus, half a degree makes a big difference for both plants, insects, and vertebrates.

Tropical areas and areas that are the warmest today are the hardest hit. Our northern latitudes can instead become an area where many species, so to speak, escape from the heat.

It may even be that as it gets warmer here we get greater population growth of certain species, maybe pests in agriculture and so on. There are many indications. For example, we have received many new insect species as a result of higher temperatures.
