“How will the increasing frequency of droughts affect conventional power generation?”

Although usually thought of as being completely self-sufficient, conventional power generation relies a great deal on water for its operations. With the increasing frequency of droughts induced by climate change, water will become a more scarce resource in many parts of the globe, therefore reducing a vital feedstock for conventional power. This is How Climate Change Induced Droughts Will Impinge upon Conventional Power Generation.

“What are the ramifications of the loss of the Amazon?”

The Amazon is burning at an unprecedented rate. If the rain forest were to loose another fifth of its area, the world would be permanently scarred. Since the Amazon recycles its own water, if too much of it becomes deforested then the water will seep out, causing a dieback cycle which would turn the rain forest into a savanna. Not only will this be a death knell to its unparalleled biodiversity and indigenous communities, but it would also turn the area from a carbon sink to a carbon emitter, thereby accelerating climate change drastically. Global weather patterns would also be drastically altered and could lead to a drying of the agricultural U.S Midwest during growing season. These are The Consequences of the Destruction of the Amazon.

“How can forests suddenly die and emit carbon?”

Forests are one of the greatest carbon sinks available on this planet. However, with the changing climate, the conditions that led to their life are now changing. Induced heat stress and the spread of pathogens are causing entire forests to wither away and release stored carbon. This Forest Dieback can create a positive reinforcement cycle in which the more trees that die the worse the climate becomes, leading even more trees to die off. Two of the most extreme cases of this are in the Amazon rain forest and the Boreal forest, where large portions of the former is actually turning into a savanna.

Why Fires are Growing at an Exponential Rate in the Brazilian Rain Forest?

Why Fires are Growing at an Exponential Rate in the Brazilian Rain Forest?

“Why are there so many more fires in the Brazilian Amazon now and what are the consequences?”

One of the worst ecological disasters ever recorded is happening as we speak. Brazil has recorded an increase of wildfires by 80% compared to last year. Much of this increase is human-caused and concentrated in the Amazon, where the new government is trying to develop it for commercial purposes. This is incredibly dangerous, as the Amazon rain forest is one of the largest sinks for carbon dioxide but could become a carbon source if it becomes deforested and dries out. This is Why Fires are Growing at an Exponential Rate in the Brazilian Rain Forest.

“What happens when a municipality runs out of water?”

Around the world, increasing temperatures, population, and levels of consumption are putting a strain on municipal water supplies. In fact, many of these areas can now even predict the day that they run out of water. To avoid this Day Zero, municipalities need to consider resilience strategies in regards to their water supplies, and even take measures as drastic as Cape Town’s.

“How will there be more water crises because of Climate Change?”

With the advent of the changing climate, almost every environmental variable will be affected. In particular, areas which have dry climates will become dryer. This means less water will be produced, leading to shortages. Such shortages will cause haphazard issues for infrastructure systems designed for greater supplies of water, resulting in difficult tensions. An illustration of this can be found in Cape Town, South Africa, where a dry spell caused the municipality to enact draconian water supply restrictions. This is How Climate Change Will Lead to Water Crises.

“How did the city of Cape Town get itself out of a water crisis and how can other cities learn from it?”

At the beginning of 2018, the city of Cape Town was facing a devastating problem. Given the current supply of water and usage rates, the city was projected to run out of water within the year. Realizing the direness of the scenario, the city government issued a dire warning. If the water in the damns became too low, the municipality would shut off the taps on a day labeled “day zero”. To ensure citizens would cooperate, the city placed a 50 liter/day limit to water usage (for reference, the average daily per capita use in California was 321 liters), and anyone who went over would be heavily fined or even have their water shut down. Residents took heed, and began rationing water and using it as efficiently as possible. As a result, Cape Town was able to lower its water usage, achieve sustainability and avoid day zero. As droughts become a larger problem in the future with climate change, cities should learn from Cape Town in how to grapple with these problems.
