Climate Change Will Hit Genetic Diversity By Virginia Gewin of Nature magazine Climate change represents a threat not only to the existence of individual species‚ but also to the genetic diversity hidden within them‚ researchers say. The finding promises to complicate assessments of how climate change will affect biodiversity‚ as well as conservationists’ task in preserving it. DNA studies have revealed that traditional species‚ as defined by taxonomists

Approximately every 100‚000 years Earth’s climate warms up temporarily. These warm periods‚ called interglacial periods‚ appear to last approximately 15‚000 to 20‚000 years before regressing back to a cold ice age climate. At year 18‚000 and counting our current interglacial vacation from the Ice Age is closer to its end than its beginning (Geo Craft). This leads to the growing debate of today‚ is global warming man-made? Or is it just a cycle that the Earth goes through? This is a controversial

Climate is a measure of the average pattern of variation in temperature‚ humidity‚ atmospheric pressure‚ wind‚ precipitation‚ atmospheric particle count and other meteorological variables in a given region over long periods of time. Climate is different from weather‚ in that weather only describes the short-term conditions of these variables in a given region. A region’s climate is generated by the climate system‚ which has five components: atmosphere‚ hydrosphere‚ cryosphere‚ land surface‚ and biosphere

Fact Sheet: Climate Change in Australia Over Millions of years The Ice Age – The Cryogenian Period (850-630 million years ago) Even though there wasn’t ice everywhere when the ice age occurred‚ Australia and the rest of the continent were majorly affected by ice glaciers (known as bulldozers). Due to the environment being very cold and the outskirts of the glaciers turning into artic deserts‚ glaciers preserved the fossils of various plants and animals. Based on this fossil evidence‚ it is proven

Climate Change and the Ross River Virus Climate change may be a politically contentious issue‚ but the scientific community has reached a consensus: it is real and the effects could be disastrous (Hughes‚ 2003). Within the next century‚ there will be changes in rainfall patterns‚ rising sea-levels and significant temperature increases‚ as well as the impact these conditions will have on flora‚ fauna and disease transmission (Hughes‚ 2003). Of particular concern to Australia is how these changes

This August‚ a friend of mine who is passionate about climate change and food justice recommended to me the documentary Cowspiracy because it played a huge role in her becoming a vegan. I watched it with my mom‚ and both of us immediately became vegetarians. The documentary discussed‚ analyzed‚ and brought to light animal agriculture’s significant role in climate change. I used to love meat—particularly hamburgers and bacon—but the evidence that the film presented on animal agriculture’s impact on

While climate change is part of daily conversation‚ it gets disguised as something else. Whether we are talking about climate change on the farm‚ in the classroom‚ or in Washington‚ people shy away from uttering the words itself. Instead‚ they disguise it as “just talk about the weather”‚ like Gil Gullickson says‚ an editor for Successful Farming magazine. The article I have chosen‚ highlights the different realms in which we discuss the current change in climate. The article “In America’s Heartland
