The burning of the fossil fuels is considered as the major contributor towards climate change. Some of the most devastating impacts of climate change include warming oceans, melting glaciers, suffocating oceans, etc. It is predicted that by the year 2050, the climate change alone threatens the extinction of approximately one quarter or more of all species on land. Due to the acidity of oceans, suffocation of oceans and warming oceans, it is also forecasted that species in the oceans or in fresh water are also at great risk from climate change.
Species like coral reefs that live in the ecosystem are highly sensitive to warming temperatures. Climate change is considered as a threat to species because they have evolved to live within certain temperature ranges. When the ecosystem in which species lives, experiences a temperature change, the species cannot adapt to the new temperatures, putting a question on their survival.
Climate researcher Prof. Midgley suggest that rapid changes in climate accelerate biodiversity loss as it damages the ecosystem. Prof. further suggests that limiting the increase in global temperature to 1.5 degrees may also prove hazardous in case it is not guided by careful analysis. Prof. also told that biofuels may generate fewer emissions than fossil fuels but to making way for biofuel by the clearing of natural vegetation can reduce carbon storage and extract a high price in biodiversity and ecosystem services.
Putting stress on biodiversity protection, Prof. Midgley, suggests that climate change mitigation and adaptation can be achieved by protecting biodiversity. Protecting biodiversity along with combining other efforts to reduce emissions of greenhouse gasses can make major contributions to climate mitigation.
Climate change means ocean change
In the published interview, researcher Ove Hoegh-Guldberg suggests that due to rapidly increasing greenhouse gas concentrations, the ocean ecosystem is experiencing conditions that have not been seen for millions of years. He further suggested that climate change has gone beyond death, extinctions and habitat loss.
The oceans are getting warmer due to climate change and global warming. Owing to this, fundamental processes are being altered, making it change in the ocean ecosystem. The solubility of oxygen in warm water is low. Due to this, the ocean water is experiencing depreciation in the level of oxygen. Because of this, some of the species are moving from areas having low oxygen to areas having higher oxygen. This mobility of marine species is offering a tremendous impact on the overall ecosystem.
Acidification of ocean water is also disturbing the biodiversity in oceans. The emission of Co2 on land is also impacting the ocean water as it gets dissolved in the ocean, making these more acidic. These changes in the oceans’ chemistry disrupt the ability of plants and animals in the sea to make shells and skeletons of calcium carbonate- depleting carbonate ions in the ocean — the building blocks for many marine organisms.
Researches and studies are clearly indicating that climate change is adversely impacting biodiversity. These impacts are considered as quite far as are visible.
