Answer:

To control Earth’s mounting climate emissions, we really have our work cut out for us.

First, greenhouse gas emissions must be reduced to nearly zero by 2050 to prevent massive sea level rise, drought and heat waves. But that isn’t enough, since already-emitted carbon dioxide lingers in the atmosphere for millennia. To meet climate goals, this harmful gas must be removed from the air in a process called “negative emissions,” according to scientists at the virtual Comer Climate Conference this fall.

“There’s no scenario that keeps us under even 2 degrees [Celsius of warming] without negative emissions,” said physicist Raymond Pierrehumbert of the University of Oxford.

That is, no realistic scenario, he added.

“If you wave a magic wand” to erase CO2 emissions, that would prevent catastrophic warming, Pierrehumbert said in an email.

Though there’s no magic wand, the Earth does have a few defenses against changing climates. Some natural chemical reactions take carbon dioxide from the atmosphere and store it away. On their own, these methods take many thousands of years, but they would remove CO2 much more quickly if humans could accelerate them.

To succeed, though, the world must dramatically reduce emissions with green energy alternatives such as solar and wind. That way, the negative emissions techniques remove CO2 that’s already accumulated in the atmosphere.

Chemical reactions with rocks

If it weren’t for silicate weathering, Earth would be a hot, almost Venus-like hellscape. Carbon dioxide mixes with rain and causes the weathering, or breakdown, of rocks. This sets in motion chemical reactions that remove CO2 from the atmosphere and store it as minerals hidden away on the ocean floor.

This process has helped control Earth’s temperature throughout history.

“If it gets hotter, the silicate weathering goes faster, and it pulls CO2 out of the atmosphere. And if it cools down, silicate weathering slows down, so CO2 builds up,” said R.J. Graham, a doctoral student at the University of Oxford. “So it sort of acts as a thermostat for Earth’s climate.”

But now, human-forced climate change is warming Earth too quickly for it to be controlled by natural silicate weathering, which can take hundreds of thousands of years to work. To have a larger impact, Graham said we’d have to use enhanced weathering to speed up the process.

Some pieces of green olivine

A silicate rock called olivine is particularly good for removing CO2 through weathering. If people mined olivine, broke it into tiny pieces to increase its surface area and distributed it on land or in the oceans, it would get weathered at high rates and remove lots of CO2.

“[This idea] hasn’t really had as much attention paid to it as I think it deserves,” Graham said.

Enhanced weathering has the potential to lower atmospheric CO2 concentrations — which currently sit at the unsafe level of over 410 ppm — by 30 to 300 ppm by 2100, according to a report in Nature Climate Change.

A nonprofit called Project Vesta, unaffiliated with the Comer conference, hopes to create beaches with the ‘sand’ made of crushed olivine. Ocean waves will weather the rock quickly, and at scale, this could remove a lot of carbon dioxide from the air.

But it’ll take a lot of rock — to neutralize one year of carbon emissions, it takes a cube of olivine 6.34 miles on each side. Though it’s not as much as the coal mined each year, that cube would be taller than Mt. Everest, which is just under 5.5 miles high. And that’s not the only challenge.

“It’s an interesting concept, but it also might be dangerous, because you’re dumping a lot of rocks into the ocean that’ll have a lot of other trace metals and things that might screw with the biology in the oceans,” Graham said. “It’s something that needs to have a lot more research done.”

Silicate weathering does affect the oceans — it ultimately makes them more basic, or alkaline. Making the oceans more alkaline helps take CO2 out of the atmosphere, and other scientists are studying how to make that happen.

The big, blue carbon sink

Earth’s oceans help to slow climate change by absorbing carbon dioxide, but as they do, the water becomes more acidic. If compounds were added to the oceans to make them less acidic and more alkaline, the oceans would pull even more CO2 out of the air.

Some scientists explore ways this process called ocean alkalinity enhancement could remove CO2 from the atmosphere. Sophie Gill, a final-year Ph.D. student at the University of Oxford, wants to know what effect this has on marine life.

The population density of Ankara is 531 people per square mile which is equivalent to 205 people per square kilometer.  

The capital of Turkey, Ankara is covering a total of 9,468 square miles which is equivalent to 24,522 square kilometers. It is one of the largest cities in Turkey, second only to Istanbul, and has a calmer but more political environment.

Massive population growth occurred in Ankara in the 1950s when it was flooded by people who migrated for better jobs, better houses, and obviously, a better quality of life. The city still has a fast-growing population, which grew significantly yet again between 2014-2015.

Answer: strait of sicily

Explanation:

The straits that separate the Black and Mediterranean seas is the strait of Sicily. Thus, option fourth is correct.

A strait is an oceanic landform that connects two oceans or major bodies of water. Surface water flows at the same elevation on both sides of the strait and in either direction. It is most typically a small maritime corridor that connects two land masses.

The Black Sea is linked to the Mediterranean Sea by two small straits: the Bosporus Strait (Strait of Gallipoli), which links to the Sea of Marmara (Turkey), and the Dardanelles Strait (Strait of Gallipoli), which connects to the Aegean Sea. The Waterway of Sicily is the strait that connects the Black and Mediterranean seas. As a result, option four is correct.

Agritourism presents a unique opportunity to combine aspects of the tourism and agriculture industries to provide a number of financial, educational, and social benefits to tourists, producers, and communities. Agritourism gives producers an opportunity to generate additional income and an avenue for direct marketing to consumers. It enhances the tourism industry by increasing the volume of visitors to an area and the length of their stay. Agritourism also provides communities with the potential to increase their local tax bases and new employment opportunities. Additionally, agritourism provides educational opportunities to the public, helps to preserve agricultural lands, and allows states to develop business enterprises. While agritourism may create new potential revenue streams, it also presents new legal issues for farmers and landowners.

The land that supplies water to the river system is called a Watershed.

Pollution from a single, identifiable source is called point source pollution.

Pollution that is difficult to link to a particular origin is called non-point source pollution.

A watershed is a land area that channels rainfall and snowmelt to creeks, streams, and rivers, and eventually to outflow points such as reservoirs, bays, and the ocean.

Point source pollution is a single identifiable source of air, water, thermal, noise or light pollution.

Non-point source pollution is a kind of pollution that occurs when runoff from rain and snowmelt carries pollutants into waterways such as rivers, streams, lakes, wetlands, and even groundwater.

Answer: A climate zone results from the climate conditions of an area: its temperature, humidity, amount and type of precipitation, and the season. A climate zone is reflected in a region’s natural vegetation. Perceptive travelers can figure out which climate zone they are in by looking at the vegetation, even if the weather is unusual for the climate on that day.

The major factors that influence climate determine the different climate zones. In general, the same type of climate zone will be found at similar latitudes and in similar positions on nearly all continents, both in the Northern and Southern Hemispheres. The one exception to this pattern is the climate zones called the continental climates, which are not found at higher latitudes in the Southern Hemisphere. This is because the Southern Hemisphere land masses are not wide enough to produce a continental climate.
