Presently, climate change is a great concern because of the effects associated with it. It is, for instance, a cause of global warming that has resulted in a high rate of a rise in sea levels. The Intergovernmental Panel on Climate Change (IPCC) projects an exponential increase in global temperatures at least 2.7°F in the 21st century (The National Wildlife Federation, 2019). As a result of climate change, marine life including plant species have been affected by the rising temperatures. Calanus finmarchicus is among the species that behave differently and shows a shift in its distributions as a result of climate change.
Wilson et al. (2016) note that, as temperatures increase, Calanus finmarchicus species have been moving further to the north of the Northern Sea. The northward shift of Calanus finmarchicus is an indication that the population of the species has been adopting to the changes in climate. However, there is further research to establish Calanus finmarchicus distribution and level of effect of increasing temperatures on the species. The species is highly vulnerable to global warming effects as noted by Grieve, Hare and Saba (2017), especially in the Northeast U.S. Shelf. It is estimated that its density will decrease by an estimated 50 percent by 2081-2100 because of the high levels of greenhouse gas emissions. The Northeast U.S Shelf is projected to have a 32 percent reduction in the density of Calanus finmarchicus by 2081-2100.

The global effect of climate change has increased to nearly 40 percent stronger as noted by Biello (2013) because of emissions of greenhouse gases. In this context, it is unjustified to assert that conservation should focus on reducing climate change rather that of attempting to reverse the root causes of the issue. Instead, it is imperative to address the root causes of climate change including emissions of greenhouse gases. For instance (Eaton, 2014) note the need to focus on renewable sources of energy as a measure to address the root cause of climate change.
