Climate change deniers won’t agree to this, but here’s what science has to say about climate change and its effects – it has already started impacting everything from our genes to entire ecosystems throughout the planet.
According to scientists at the University of Florida, climate change has in store unpredictable consequences for humans and while the general public won’t see the things as they are from the scientific viewpoint, a staggering 80 per cent of 94 ecological processes that are considered to be the foundation for healthy marine, freshwater and terrestrial ecosystems across the globe are already show signs of distress and responding to climate change.
Researchers at the university point out that they have found genes to be changing as well as species are also changing. They claim to have found clear evidence that climate change has caused about physiological and physical changes in species including change in body sizes and there are now signs of entire ecosystems under stress.
As far as humans are concerned scientists say that we will see increased attacks of pests as well as diseases and as far as productivity in fisheries and agriculture is concerned, they will decline.
Scientists claim to have observed astonishing level of changes despite the fact that the climate change is relatively small. They have called upon authorities and policy makers and asked them not to consider the impact of climate change as something that will happen in the future. It has already started happening and policy makers and politicians must accept that if the right steps are not taken at the right time including curbing of greenhouse gas emissions we are bound to witness an environmental catastrophe sooner than later.
But the study also points to hope as many of the responses observed in nature could be applied by people to address the mounting issues faced under changing climate conditions. For example, improved understanding of the adaptive capacity in wildlife can be applied to our crops, livestock and fisheries. This can be seen in crops such as wheat and barley, where domesticated crops are crossed with wild varieties to maintain the evolutionary potential of varieties under climate change.
