Throwing Chemicals Into The Air – Solution to Global Warming?

Certain bright minds say we should throw trillions of mirrors into space to slow global warming. It doesn’t seem like a bad idea at a first glance, but other enlightened thoughts say we should release chemicals into the air to do just that.

The idea came to them in 1991, when Mount Pinatubo erupted and ejected about 15,000,000 tons of sulfur-dioxide-laden dust into the atmosphere. Because of that event, the global average temperature dropped about 0.6°C for almost 2 years.

The effect the scientists want to artificially recreate already exists naturally, and it’s called “global dimming”. Saying it exists naturally is a little bit exaggerated, because smog particles create that light blockage, and dim the sunlight proportionally with the pollution. In a way, you could say it’s nature’s own way of defending itself, but there are certain aspects we should consider.

One such aspect is that by blocking sunlight to reduce heat, we also reduce the capacity of our only viable way of producing energy: solar power.

Daniel Murphy, a physicist at the NOAA’s (National Oceanic and Atmospheric Administration) Earth System Research Lab in Boulder, CO, attempts to quantify the reduction in light that such a geoengineering scheme would bring.  He calculated a dim of about 3 percent, which translates into less with 5 watts per square meter of photovoltaic panels.

You also could think of this two ways:

1. You might say: “ok, 5W/m is our loss, but we’ll increase the area, and we’ll research more efficient cells, so we’ll offset that. What’s important is we don’t fry ourselves like toast here on Earth”
2. The world’s energy needs increase, we don’t have anything certain under our feet, the oil drillers keep the oil business with their teeth, and there’s more and more need of recyclable power. Plus, we do not only affect our photovoltaics, but also our plants and ecosystems. You may have seen what a slight change is ecosystems does – just watch Katrina’s devastating effects.

So, where’s our option? Somewhere in between?

  1. I would like to share my interest as one of the principals of Royal Wind we have designed an Ocean Temperature Regulatory System using our revolutionary turbines to power cold water pumps. Our system is designed to pump large amounts of cold water to the surface of the ocean to create cold water thermoclines. We believe that widespread use of our system worldwide would result in a much desired global temperature regulation and reduction. The health of our oceans and the increased carbon sequestration are linked to global sustainability. We feel that without intervention the oceans are in danger of collapse. The health of our oceans is crucial to the maintenance of oxygen levels in the atmosphere. If the oceans die, we will struggle to survive. It’s all connected: ocean health, carbon sequestration, and global temperatures. Here’s the plan:

    To install our ocean-current powered cold water pumps in strategic locations worldwide, creating cold water thermoclines, increasing the sequestration of anthropogenic carbon dioxide. Our system will also be used to build the polar icecap back to a more acceptable year-round base level which will also ensure the continued function of the thermohaline and of the North Atlantic drift. Our system will also be used to create cold water barriers to hurricanes. We can solve the Earth’s problems with the right effort. We must if we plan to continue living on this Earth.
