CO2
Tree-Planting Drones
One of the major causes of the increasing carbon dioxide levels in the atmosphere is deforestation. We chop down about 15 billion trees each year. Over time, our activities have reduced the number of trees on earth by about 50%. We do plant trees – these days, about 9 billion a year. It is a substantial number, but still leaves a net loss of 6 billion trees annually.
Natural Climate Solutions
The Paris Climate Agreement embodies a commitment to hold the increase in the global average temperature to less than 2 Celsius degrees above preindustrial levels. Most strategies to achieve this goal involve reductions in greenhouse gas emissions from human activities such as burning fossil fuels as well as various land use activities. But there are also so-called Natural Climate Solutions, which relate to the storage of carbon and reduction in carbon emissions across global forests, wetlands, grasslands, and agricultural lands.
Removing CO2 With Plants
Plants are the world’s great storehouse of carbon dioxide. That is why deforestation is a major contributor to climate change. If only there were more trees and plants, more of the CO2 in the atmosphere would be absorbed and could no longer trap heat in the atmosphere.
Saving Venice From The Sea
The risks of rising sea waters are growing more apparent every year. While the world struggles with taking action to reduce the carbon emissions that are driving the sea level rise, cities around the world are building sea walls designed to protect them from storm surges and flooding. Most of these are massive, complex infrastructure projects that cost billions of dollars and take decades to complete.
Cryptocurrency And Climate Change
Bitcoin is a form of digital currency. Bitcoins aren’t printed, like dollars or euros. They are produced by people and businesses using computer software to perform the necessary complex calculations. A bitcoin is essentially a line of computer code that’s signed digitally when it goes from one owner to another. Bitcoin is the most prominent example of a growing category of money known as cryptocurrency.
Transportation And Greenhouse Gases
Power plants have been the biggest source of greenhouse gas emissions in the United States for more than 40 years. But the ever-changing picture of electricity production has changed that situation. According to new data from the government’s Energy Information Administration, transportation has now taken over the top spot.
Climate Change And Barley
The impacts of increased carbon dioxide and the changing climate are often complicated and, it turns out, not always negative. In some areas of the world, people can actually benefit from increased CO2 and climate change. Barley, the most important feed crop for beef production in Alberta, Canada, as well as the province’s beef industry itself actually stand to gain from the changes that are most assuredly not a good thing for much of the world.
Turning Emissions Into Fuel
Reducing carbon dioxide emissions is an essential element in mitigating climate change. The best approach is to not produce the stuff in the first place and the ongoing transition away from fossil fuels is trying to do just that. But realistically, fossil fuels will be with us for a long time to come. Given that, additional approaches are necessary.
CO2 Emissions Stalled
For the third year in a row, global emissions of carbon dioxide have remained unchanged. This indicates that efforts to reduce emissions have had an effect, but that there is much more to be done. It is essential to reduce emissions, not just cap them.
Fuel From Greenhouse Gases
Carbon dioxide and methane are the two greenhouse gases that are having the greatest impact on the global climate. There are basically three ways to prevent them from getting into the atmosphere: don’t emit them, trap them and store them away, or turn them into something useful.
Carbon And Heating Soil
Plants are a critical part of the Earth’s carbon cycle. They take in carbon dioxide during photosynthesis. Eventually, dead leaves, branches and other materials fall to the ground where bacteria and fungi decompose the materials and release the CO2 back into the atmosphere. This carbon-soil feedback loop is a complicated one that is critical to the overall carbon balance because soils actually contain two to three times more carbon than the atmosphere.
The End Of British Coal
In the 19th century, Britain produced 80% of the world’s coal. Britain was the dominant global power in the industrial revolution with its giant blast furnaces, steam locomotives and steam ships. And with advent of the electric age, coal once again was the power source of choice. Even as late as the 1970s, Britain got 80% of its electricity from burning coal.
Ozone Treaty And Greenhouse Gas Emissions
The Montreal Protocol, the international treaty adopted to restore the earth’s protective ozone layer almost thirty years ago, turns out to also have had a major impact on climate-altering greenhouse gas emissions.
