It is a major aspect of current climate change, and has been demonstrated by direct temperature measurements and by measurements of various effects of the warming. ]]> 2019-11-05 00:04:08 UTC https://padlet.com/ba004408/tmpvalrntr2f/wish/406596563 ba004408 https://padlet.com/ba004408/tmpvalrntr2f/wish/406597354 Did you know Australians are big producers of carbon dioxide pollution compared to the rest of the World? Our level of carbon dioxide pollution per person is nearly double the average of other developed nations and more than four times the world average? Carbon dioxide is the climate’s worst enemy. It’s released when oil, coal, and other fossil fuels are burned for energy, the energy we use to power our homes, cars, and smartphones. By using less of it, we can curb our own contribution to climate change while also saving money.

Fires normally occur around the dry season and many different methods are used to clear the forest to make way for agriculture, livestock, logging, and mining, leading to deforestation of the Amazon rainforest. Such activity is generally illegal within these nations, but enforcement of environmental protection can be slack. The increased rates of fire counts in 2019 led to international concern about the fate of the Amazon rainforest, which is the world's largest carbon dioxide sink and plays a significant role in global climate change.]]> 2019-11-11 23:10:35 UTC https://padlet.com/ba004408/tmpvalrntr2f/wish/409718145 ba004408 https://padlet.com/ba004408/tmpvalrntr2f/wish/409718293 As we all know- Plants and trees play an important role in regulating the climate because they absorb carbon dioxide from the air and release oxygen back into it and we need oxygen to breathe. However, humans clear vast areas of vegetation around the world for farming, urban and infrastructure development or to sell tree products such as timber and palm oil. When vegetation is removed or burnt, the stored carbon is released back into the atmosphere as carbon dioxide contributing to global warming. ]]> 2019-11-11 23:11:21 UTC https://padlet.com/ba004408/tmpvalrntr2f/wish/409718293 ba004408 https://padlet.com/ba004408/tmpvalrntr2f/wish/409719214 Yes, there are also some positive impacts of agriculture, but the negative impacts easily take out the positives. For example: The U.S. food system contributes nearly 20 percent of the nation's carbon dioxide emissions; on a global scale, figures from the Intergovernmental Panel on Climate Change (IPCC) say that agricultural land use contributes 12 percent of global greenhouse gas emissions. Supporting industrial agriculture perpetuates these disturbing practices. But Wait there’s more! If we consider some of the embodied energy required for industrial agriculture, it gets worse, including all the "manufacture and use of pesticides and fertilizers, fuel and oil for tractors, equipment, trucking and shipping, electricity for lighting, cooling, heating, and emissions of carbon dioxide, methane, nitrous oxide and other greenhouse gases" bumps the impact up to between 25 and 30 percent of the U.S.'s collective carbon footprint. That's a big jump! ]]> 2019-11-11 23:16:31 UTC https://padlet.com/ba004408/tmpvalrntr2f/wish/409719214 ba004408 https://padlet.com/ba004408/tmpvalrntr2f/wish/409719895 According to National climate assessment, in 2000 to 2009 was hotter than any other decade in at least the past 1300 years. This warming is altering the earth's climate system, including its land, atmosphere, oceans, and ice, in far-reaching ways.

The National Oceanic and Atmospheric Administration, in 2015 there were 10 weather and climate disaster events in the United States—including severe storms, floods, drought, and wildfires—that caused at least $1 billion in losses. For context, each year from 1980 to 2015 averaged $5.2 billion in disasters (adjusted for inflation). If you zero in on the years between 2011 and 2015, you see an annual average cost of $10.8 billion.

Ground-level ozone is the main component of smog, and the hotter things get, the more of it we have. Dirtier air is linked to higher hospital admission rates and higher death rates for asthmatics. Warmer temperatures also significantly increase airborne pollen, which is bad news for those who suffer from hay fever and other allergies.

As land and sea undergo rapid changes, the animals that inhabit them are doomed to disappear if they don't adapt quickly enough. Some will make it, and some won't. The Intergovernmental Panel on Climate Change's 2014 says that many land, freshwater, and ocean species are shifting their geographic ranges to cooler climates or higher altitudes, to escape Global warming. They're changing seasonal behaviours and traditional migration patterns, too. And yet many still face "increased extinction risk due to climate change." Indeed, a 2015 study showed that vertebrate species—animals with backbones, like fish, birds, mammals, amphibians, and reptiles—are disappearing 114 times faster than they should be, a phenomenon that has been linked to climate change, pollution, and deforestation.”

1: Produce more food on less land- Large scale agriculture is the biggest source of land conversion, it uses 70% of the world’s freshwater supply, and relies on fertilizer practices that pollute our waters.
How to fix it: Produce food in places where it is more probable to survive, which uses less water and less land area.]]> 2019-11-11 23:30:52 UTC https://padlet.com/ba004408/tmpvalrntr2f/wish/409721765 ba004408 https://padlet.com/ba004408/tmpvalrntr2f/wish/409723346 2: Eliminate Overfishing- Overfishing and poor management endangers food webs and ocean ecosystems by disrupting the balance of all sea life. Without serious changes, 84 percent of the world’s fish stocks will be in peril in our lifetime.
How to fix it: Refine our fishing methods so our oceans can be more abundant and healthier in the future.

And with global energy demand expected to increase 56% over the next couple decades, it will be impossible to meet those emissions targets if we stick primarily with traditional fossil fuels.
How to fix it: Move 85% of the world’s energy supply to non-fossil fuel sources and invest in strategies like reforestation that capture carbon dioxide.
