Negative Carbon Emission Technologies
“How can we use technology to remove carbon dioxide from the atmosphere?”
Humanity is reaching a crisis point. We are adding so much carbon dioxide to the atmosphere each second that we will soon reach irreversible climate damage. To solve this, we’re going to need to use every technology we have at our arsenal, whether it be wide arrays of solar panels or intense energy efficiency measures. But the true kingmaker of solutions comes from a group of technology that is still quite ominous and undeveloped. These Negative Carbon Emission Technologies work by using a series of processes to store more carbon dioxide than they produce. This can be done in a multitude of ways, whether it be through planting more trees or capturing carbon from the atmosphere and shoving it down into the ground. With these solutions, we can tip the odds in our favor in our fight for decarbonization.

Climate Change Attribution
“How can we attribute what is responsible for climate change?”
One of the biggest debates going on about climate change is what is causing it. Many political pundits will claim that everything can be explained entirely through natural factors such as the Earth’s tilt or volcanoes. However, to prove causation, mathematical analysis will need to be done to isolate each component and observe its effects. Using this Climate Change Attribution, we can see that these effects do not contribute greatly to global warming and that carbon emissions is the primary driver behind climate change.
Why HVDC Can Hurt Fire Resilience
“Why are the most serious drawbacks to HVDC lines?”
HVDC lines are one of the hottest topics in the renewable energy world nowadays. Their ability to transmit a large volume of electricity across great distances with minuscule losses can make them a vital part of easing the duck curve. However, their high voltage also means that if they get sapped, they have a much higher potential to produce a fire. This will have great implications for the regionalization of California, where increased connectivity to other states could bring grid stability but exacerbate the potential for chaos.
“How can you offset your carbon emissions without changing your own operations?”
Some things are extraordinarily difficult to decarbonize. Whether it be air travel or going 100% renewable when the grid itself is based 100% off carbon-emitting resources. But a workaround can be found through Carbon Offsetting. This involves making a purchase of renewable energy or planting a tree that offsets the amount of carbon used. This can be useful for designing policies around technologies whose emissions-free alternatives are still too nascent for commercial use.

How Heat Transfer is Used to Model Climate Change
“How is Heat Transfer Used to Model Climate Change?”
Heat Transfer is one of the foundational course for a Mechanical Engineer. But internal combustion engines and HVAC are not the only things that the theory can be applied to. Climate Scientists will use many of the same Heat Transfer equations when designing climate models. In this way, Heat Transfer is Used to Model Climate Change.

Climate Change Model Verification
“How can we verify climate change models?”
Climate models are extremely useful for helping us predict the impacts of climate change. But how can we verify them? Well, what if we were to map their mathematical functions to historical data and see if they accurately predict temperature rises? If it turns out to be correct, then the model has a good chance of being valid. This Climate Model Verification, often known as hindcasting, gives our methods validity for future policy work.

Carbon Neutral Economies
“How can an economy not contribute to climate change?”
Traditionally, economies have grown in tandem with carbon emissions. But with the advent of modern-day extreme climate change this is no longer feasible. To solve this, nations will have to adopt Carbon Neutral Economies in which all sectors have slashed their emissions to zero. The transition to a low carbon economy could yield enormous economic growth as well as inequality easing. Multiple governments around the world are committed to this action, with California’s 2045 and the EU’s 2050 initiatives as examples.
