Reflective Summary

Reflective Summary

I have learnt that due to climate change that one-third of all Antarctic sea ice is likely to melt by the end of the century, seriously contributing to dangerous sea level rises, and updated scientific modelling on global warming shows.my perspective have changed that climate change is that I think that the change of weather from its original status. My comments about this current situation is that I will help the enviroment by using lesser cfc products.i fear that one day we might have no place to saty as all. We can help in many ways to help stop global warming .Example to save lots of money and save hundreds on lbs of carbon from realeasing in the air is by carpooling. And because of climate change can make us starve by making it difficult to lant crops. Global warming is bad for us and affects us badly so lets all cooperate and stop global warming..!

How can we help to stop global warming?

How can we help to stop global warming?

The Stop Global Warming calculator shows you how much carbon dioxide you can prevent from being released into the atmosphere and how much money you can save by making some small changes in your daily life. It’s our hope that the calculator will promote action, awareness and empowerment by showing you that one person can make a difference and help stop global warming. There are many simple things you can do in your daily life — what you eat, what you drive, how you build your home — that can have an effect on your immediate surrounding, and on places as far away as Antarctica. Here is a list of few things that you can do to make a difference. Here are some ways you can help to stop global warming Carpool When You Can Own a big vehicle? Carpooling with friends and co-workers saves fuel. Save 790 lbs. of carbon dioxide and hundreds of dollars per year. Don't Idle in Your Car Idling wastes money and gas, and generates pollution and global warming causing emissions. Except when in traffic, turn your engine off if you must wait for more than 30 seconds. Buy Minimally Packaged Goods Less packaging could reduce your garbage by about 10%. Save 1,200 pounds of carbon dioxide and $1,000 per year. Extracted from: http://www.stopglobalwarming.org/sgw_actionitems.asp

Effects of Climate Change On Infectious Diseases

Effects of Climate Change On Infectious Diseases

Recent research has predicted that climate change may expand the scope of human infectious diseases. A new review, however, argues that climate change may have a negligible effect on pathogens or even reduce their ranges. The paper has sparked debate in the ecological community. The newly suitable areas for diseases will tend to be in more affluent regions where medicines are in widespread use and can more readily combat the diseases. The dramatic contraction of malaria during a century of warming suggests that economic forces might be just as important as climate in determining pathogen ranges. Scientists have used the fact that infectious diseases are most prevalent in the tropics to argue that warmer, wetter conditions that might occur under climate change would lead to an increase in infectious disease transmission. Warming trends over the last 60 years have led instead to an increase in hot, dry, desert-like climates. So that infectious diseases don't all increase during warm, wet weather.

Wheat shortage in the world caused is climate change.

Wheat shortage in the world caused is climate change.

I think is this goes on we will not be able to have enough rice to supply us fir life.
We must take care of your own home earth. We should stops global warming by recycling, reusing and reducing. Droughts caused by global climate change have led to a drop in wheat production, a worldwide shortage and high food prices around the world.The global wheat supply is at its lowest point in 50 years, with only an estimated 10 weeks of supply left. This has been one factor pushing the prices of bread, beer and other wheat-containing foods steadily higher
Also to blame for the global wheat shortage is rising population, coupled with increasing meat consumption worldwide. This has led to the increasing diversion of grain to animal feed. Analysts anticipate that the shortage may be resolved within 12 months, as farmers pull fallow land into wheat production. But even when the shortage resolves, food prices are only expected to keep climbing due to other factors, such as high energy and shipping cost.

carbon in the air

Carbon in the air.

Atmospheric carbon dioxide has increased from around 280 parts per million (by volume) in 1800 to around 315 in 1958 and 380 in 2005, a 31% increase over 200 years (IPCC, 2001). Other greenhouse gas emissions have also increased. Future carbon dioxide levels are expected to rise due to ongoing economic development dependent on fossil fuel usage, though the actual trend for the future will depend on economic, sociological, technological, and natural developments. The Intergovernmental Panel on Climate Change has concluded that there will be both global and regional climatic change, altered precipitation patterns, occurrence of extreme events such as droughts and hurricanes and an increase in climate variability (Houghton et al., 2001) during the next 100 years (IPCC, 1995, 2001). According to ice core climate record, today’s rising atmospheric carbon dioxide concentration, at 380 parts per million by volume, is 27 % higher than its highest recorded level during the last 650,000 years (Brook, 2005).

Climate change .

UP TO one-third of all Antarctic sea ice is likely to melt by the end of the century, seriously contributing to dangerous sea level rises, updated scientific modelling on global warming shows.The modelling is the first release of a landmark study being conducted by the global scientific body the Scientific Committee on Antarctic Research, made up of the peak scientific bodies from 23 countries including Australia. The early numbers put out by SCAR suggests the collapse of Antarctic sea-ice not only pushes up anticipated sea level rises but will threaten the numbers of native animal species including emperor penguins, humpback whales and several fish species.The initial release of research also suggests sea temperatures in the Southern Ocean are rising faster than in other oceans, and that ice melts in the Antarctic Peninsula and Western Ice Shelf will be greater and more rapid than expected.Responding to the release of the executive summary of the SCAR report, the WWF manager for Antarctic and Southern Oceans Initiative, Rob Nicoll, said the evidence was showing how quickly the effects of global warming were showing up in the Antarctic region. Ice shelves the size of small countries are crumbling away and the latest evidence from the Antarctic is showing that the effects of lobagl warming there are increasing in magnitude.
