Sustainability alliance 2018 gas pains or contractions


This is why the International Council on Mining and Metals (ICMM) has developed new membership requirements to advance the sustainability performance of the mining sector. ICMM is an international organisation dedicated to a safe, fair and sustainable mining and metals industry. Bringing together 27 mining and metals companies and 36 regional and commodity associations, ICMM has worked collaboratively for over 15 years to strengthen the environmental and social performance of the industry.

From a sustainability perspective, this is progress. But we need to remember that taking materials from the earth’s crust is not sustainable unless we prevent those materials from getting into nature. (The Natural Step’s first principle.) Those materials have been buried safely for millions or billions of years, so life evolved expecting low concentrations of those materials. A little bit of zinc and iron in your body is good; too much and you’re dead. Even a little bit of arsenic, lead or uranium can threaten your health. So we need a Circular Economy where all these mined materials are recovered and put back into new products again and again.

Over 5 million people in the US are Native American. Probably the first thing that comes to mind are reservations. But 70 percent live off the reservation, feeling like ghosts in society. gas 0095 Every media outlet seems to have at least one Hispanic and African American (hopefully no longer as tokenism but as a way to reflect the diversity of our country), but can you think of a single media outlet with a Native American? What about a movie with a Native American playing an everyday role (doctor, detective NOT on the reservation, scientist, conductor), not as a stereotype?

It certainly matters to the tribal members to be invisible. But it also matters to all the rest of us. There are things the broader society needs to learn and adopt from their cultures. gas in back symptoms My niece recently went on a field trip/service trip to a couple reservations. She came home having learned some of the tricks of dry land farming, growing crops without irrigation. As water supplies become more scarce in the Southwest, that could be a helpful skill, given that over 70% of water is used by agriculture.

In the US, “A rising tide raises all boats” has been used to justify unfettered growth in certain areas. The maxim might have been true at one point in our history but research shows it’s no longer the case. This economic inequality, I believe, is central to our political schism, reflected in the 2016 presidential election both in Trump and Bernie Sanders. They just had widely different perspectives on how to fix it.

You might assume these disparities are a recent phenomenon, triggered by the Great Recession that began in 2008. gas pump heaven But economists who’ve studied the problem have found that its roots go back decades. Before 1980, there were richer and poorer areas of the United States, but income growth tended to be roughly equivalent, and the regions were even converging. But starting around 1980, that trend reversed. Some cities and communities, primarily on the coasts, continued to add jobs and increase wealth. Other cities and communities, often in the heartland or dependent on industry, began to stagnate or decline.

The day after the midterms, I was thinking the answer might be No. I could feel myself sinking into despair: our inability as a species to take the long view, to not foul our own nest, to be willing to expend a little self-control now for the benefit of future generations. Washington’s carbon fee didn’t pass. Colorado voted not to extend a safe zone for natural gas drilling to 1/4 mile from houses. Arizona’s renewable energy standard went down to defeat.

Still, you could choose to look at your glass of petrochemicals as being half full. “Ballot measures are often susceptible to misinformation and lots of out-of-state money pouring in, and there are limitations on what a ballot measure can cover,” says Dylan McDowell, deputy director of the National Caucus of Environmental Legislators, a group that helps state legislators enact climate laws. “State legislation is more able to deal with something as complex as carbon pricing.”

Thanks to Democratic takeovers of governorships and state houses in 2018, that’s now more likely. New York, Colorado, New Hampshire, Maine, and Minnesota now have pro-environment majorities. Massachusetts is moving toward carbon pricing; Oregon legislators will probably vote on a cap-and-trade law next year. The governors-elect of Illinois, Colorado, and New Mexico all campaigned on renewables. And California still has its cap-and-trade system for carbon, and a new governor fired up to head into combat with the president. So the state level may still be a place for climate legislation.

If we didn’t have certain gases in the atmosphere trapping infrared energy, our planet would be as cold as Mars. Too much and you get Venus, so hot it can melt lead. electricity projects ks2 Interestingly, any gas with three or more atoms creates a greenhouse effect. (Source: American Chemical Society). So greenhouse gases include carbon dioxide (CO 2), methane (CH 4), and sulphur hexafluoride (SF 6, that was for a time in Nike Air Jordans). Even water vapor (H 2O) can act as a greenhouse gas.

Roughly 98% of our atmosphere is nitrogen and oxygen with only two atoms each so they’re not greenhouse gases (N 2 at 78% and O 2 at 21%) which leaves only about 1% for all the other gases, mostly argon. So it’s a teeny, tiny percentage of the gases that keep our climate stable. It doesn’t take a lot to throw that out of balance. electricity journal It’s not like adding another cup of tomato sauce to your chili; it’s more like adding an extra cup of jalapeño chili powder to the recipe. Concentrations matter.

Scientists have been monitoring the rise in CO 2 at the Mauna Loa Observatory since 1958. Since pre-industrial levels, we have increased the CO 2 in the atmosphere by over 40% (from about 280 ppm to over 400 now.) This trend follows the same path as the use of fossil fuels. It’s really quite simple. If we take hydrocarbons from their ancient burial place in the earth and burn them, releasing them to the atmosphere at a much greater rate than Nature can put them back, they build up.

A lot of the CO 2 has been absorbed by the oceans, which is making the ocean measurably more acidic. But methane represents about 40 percent to the heat-trapping effect of all human-produced greenhouse gases in the atmosphere . Methane comes from natural gas (much of it leaking out of pipes) and also from rotting organic matter (like food in landfills and thawing permafrost.)

Think of our planet as a box with a pipe of greenhouse gases coming in and a pipe going out. For most of the last 10,000 years, the size of the two pipes were balanced, the same amount of greenhouse gases coming in and going out. Humans have not only increased the amount coming into the box with fossil fuels and other chemicals. electricity nightcore lyrics We’ve also reduced the size of the pipe going out. For example, deforestation has reduced Nature’s ability to take CO 2 out of the air. Sometimes cycles make things progressively worse. For example, the oceans have absorbed a lot of human-made CO 2 but as the ocean warms, it can’t hold as much gas. (Think of your soda going flat on a warm day.) Or as sea ice melts, it reveals a darker ocean that absorbs more heat than the ice did, speeding up the rate of warming.

Any system is going to have a reaction to significantly different concentrations. Imagine increasing your fat intake by 40 percent or your body temperature. f gas regulations Exactly what will change where, by how much, by when are very complicated questions to answer. But continuing to add greenhouse gases to the atmosphere will clearly change the climate. According to the world’s scientists, it already is. But you don’t have to ask them. You can see spring coming sooner, glaciers retreating, and sea level rising.

• Scientists only disagree about the details. My brother was trained as a scientist and I’ll tell you, they love to argue and poke holes in one another’s theories. The disagreements around climate science tend to be about how the impacts will play out. But 97 percent of the world’s climate scientists agree the climate is changing and that humans are the primary cause.

Imagine you take your child to a doctor because you’ve noticed some worrisome symptoms. The doctor tells you the treatment may cost some money and be inconvenient but without treatment, the disease is likely life-threatening. You go for a second opinion and a third. Eventually you see 100 doctors, 97 of them saying the same thing. But a couple doctors say, "Hey, she might grow out of it, take some Vitamin C and hope for the best." What do you do? Most people listen to the 97 doctors. That’s where we are regarding the climate.

• Climate change (what many call global warming) can make some places colder at times. It’s doing some odd things to weather patterns, bringing cold arctic air into the US at times. 5 gases It’s better to think of it as destabilizing the climate. Some people in cold climates welcome spring coming sooner. But we depend on a predictable climate: when to plant crops, when the rains will come, what weather we need to construct buildings to withstand, etc.
