Description

As Editor-in-Chief, it is my distinct honour and privilege to welcome you to Our Journal of Environmental and Toxicology Studies.

The Journal of Environmental and Toxicology Studies aims to spread knowledge and promote discussion through the publication of peer-reviewed, high quality research papers on all topics related to Eco-Toxicology. The open access journal is published by Insight Medical Publishing who hosts open access peer-reviewed journals as well as organizes conferences that hosts the work of researchers in a manner that exemplifies the highest standards in research integrity.

Abstract

The research team has analyzed recent results from 40 different climate models. Using these models, the researchers considered the future evolution of Arctic sea-ice cover in a scenario with high future CO2 emissions and little climate protection. As expected, Arctic sea ice disappeared quickly in summer in these simulations. However, the new study finds that Arctic summer sea ice also disappears occasionally if CO2 emissions are rapidly reduced.

"If we reduce global emissions rapidly and substantially, and thus keep global warming below 2 °C relative to preindustrial levels, Arctic sea ice will nevertheless likely disappear occasionally in summer even before 2050. This really surprised us" said Dirk Notz, who leads the sea-ice research group at University of Hamburg, Germany.

Currently, the North Pole is covered by sea ice year round. Each summer, the area of the sea ice cover decreases, in winter it grows again. In response to ongoing global warming, the overall area of the Arctic Ocean that is covered by sea ice has rapidly been reduced over the past few decades. This substantially affects the Arctic ecosystem and climate: The sea-ice cover is a hunting ground and habitat for polar bears and seals, and keeps the Arctic cool by reflecting sunlight.

Our Journal emphasizes high-level research and education. Original research articles, reviews, short communications, and letters to the editors in the fields of ecotoxicology are welcome. Every effort is made to have a speedy and critical peer-review process.

We always encourage new research works under the scope of our Environmental and Toxicology Studies Journal. (Tap on the link to submit a manuscript)
