Three Threats of Climate Change Due to Illness

October 25th, 2011

Research recently said that global warming may affect health. A variety of emerging diseases, mostly caused by microbes, bacteria, and algae. Scientists have estimated would increase the death rate due to heat waves, natural disasters, and malaria.

Some scientists are funded by The Ocean and Human Health Initiative of the National Oceanic and Atmospheric Administration (NOAA) will identify the risk of disease due to global warming. The results are as follows.

Seafood Contamination by Toxic Algae
Red algae that cause dead zones in the ocean is growing rapidly in line with global warming, especially in North America. This was disclosed by Stephanie Moore of NOAA. Algae Alexandrium catenella which produces toxins that can contaminate food from the sea and lead to paralysis – even death, although rare – in humans.

By calculating the water temperature and an increase in global temperatures, Moore and colleagues at the University of Washington, describes how the algae can thrive. “The season bloom of toxic algae grew longer and the amount of algae that bloom each season was increased,” said Moore. “Now, the algae bloom season for two months, but in years to come, bloom period will increase to three months,” he added. » Read more: Three Threats of Climate Change Due to Illness

Hurricanes Lose Effectiveness Carbon Sink

October 21st, 2011

Any interruption to the natural ecosystem can lead to increased variability of the global carbon balance. A recent study reported that the Swedish-speaking storms can reduce levels of carbon absorbed by forests in large numbers. Adaptation to climate change and concessions are of great attention by the European climate change program (EEPC) in the second stage. In designing policy on climate change, it is important to understand the process of adding carbon to the atmosphere as well as how to eliminate it. The removal of carbon from the atmosphere then this is referred to as carbon sinks or carbon emissions.

So great is the role of forests, deeply felt its function as a reservoir of carbon emissions, which is certainly in large numbers. In the event of disruption caused by both natural and otherwise, it will be disrupted also function as a reservoir / sink carbon sink. Disruption of these forests can be said as a result of illegal logging, damage from insects, forest fires, the presence of high winds (wind throws) so that the tree uprooted / fallen, particularly storm damage.

A study has been conducted to measure directly affects how the wind throws the change that took place this continuously. The review was conducted on Gundrun storms, ie storms that occurred in southern Sweden in January 2005. The study goal was to see the effect of carbon sinks Gundrun storm in Sweden. » Read more: Hurricanes Lose Effectiveness Carbon Sink

Endangered turtles Australian Climate Change

Elusor tortoise macrurus (Mary River turtle), which is only found in the river in Australia, endangered if the temperature rises continuously. It was raised at the conference Society for Experimental Biology Annual called 3 July 2011, researchers from the University of Queensland says.

In the study conducted, researchers incubating turtle eggs in temperatures 26, 29, and 32 degrees Celsius. Result, the baby turtles that come from the most high-temperature incubator decreased ability to swim the most severe and preferred move in shallow water.

According to researchers, the combination of psychological and behavioral effects this has two consequences for their chances to survive. “The waters in not only provide protection for baby turtles from their predators, but also a place for them to find a supply of food,” said Mariana Micheli-Campbell. Meanwhile, “The baby turtles that have poor swimming ability is only around the surface are unable to find food and threatened with arrest by the birds of prey,” said Micheli-Campbell. » Read more: Endangered turtles Australian Climate Change
