What is one of the criticisms of the Kyoto Protocol *?

One criticism is that climate change is a unique environmental issue, but the Kyoto Protocol followed the format of the other international treaties (not necessarily useful for environmental issues) instead of promoting innovation in approaching the issue of global warming.

How much do automobiles contribute to global warming?

Car Emissions and Global Warming Our personal vehicles are a major cause of global warming. Collectively, cars and trucks account for nearly one-fifth of all US emissions, emitting around 24 pounds of carbon dioxide and other global-warming gases for every gallon of gas.

Which human activity contributes the most carbon dioxide to the atmosphere quizlet?

The main human activity that emits CO2 is the combustion of fossil fuels (coal, natural gas, and oil) for energy and transportation.

How much car turd is released from cars in the US every day?

In the U.S., there are a total of about 100 million cars on the road, releasing about 330,000 tons of carbon per day. When we include the rest of the world’s one billion cars, we reach 3,000,000 tons of car turds—every day. And that’s just cars.

Is Kyoto Protocol a success or failure?

In 1997 the Kyoto Protocol was born. It was the first international agreement of its kind, a revelation that would stabilise greenhouse gas concentrations in the climate to “prevent dangerous anthropogenic interference with the climate system”. The Kyoto Protocol was therefore a huge success.

What were the strengths and weaknesses of Kyoto Protocol?

The Kyoto Protocol’s main strength may lay in its emissions trading feature—a key for cost-effectiveness, environmental effectiveness, and equity. Its main weakness may lay in the incapacity of Kyoto-type targets to deal with the uncertainties surrounding climate change — especially on the side of abatement costs.

Why cars are bad for the environment?

The transport sector burns most of the world’s petroleum and is one of the largest sources of global greenhouse gas emissions. It’s also heavy on air pollution. cars are a major contributor to air pollution producing significant amounts of nitrogen oxides, carbon monoxide, and particulate matter.

Do planes or cars pollute more?

Admittedly, air transport is extremely polluting – but so are cars. Air traffic represents less than 2-3% of the global CO2 emissions whereas road traffic accounts for around 10% of these direct emissions. Still, planes remain among the most polluting means of transport, together with cars.

How would an increase in the concentration of greenhouse gases most likely affect ecosystems worldwide?

However, beginning in the late 1700s, the net global effect of human activities has been a continual increase in greenhouse gas concentrations. This change in concentrations causes warming and is affecting various aspects of climate, including surface air and ocean temperatures, precipitation, and sea levels.

Where does most of the carbon dioxide released by human activities come from quizlet?

an increase in global surface temperatures. The majority of the world’s energy is produced by burning fossil fuels. Fossil fuel combustion results in the release of carbon dioxide and other greenhouse gases into the atmosphere.

What is one reason that carbon dioxide is increasing in the atmosphere today?

Carbon dioxide concentrations are rising mostly because of the fossil fuels that people are burning for energy.

Is Istop bad for engine?

Does stop-start help save fuel? Yes – in situations where you’re stationary with the engine idling, such as in heavy traffic or waiting for traffic lights to change, it will save however much fuel would have been used by the engine while the car is stationary. Obviously, more stationary time means more fuel saved.

Does auto stop really save gas?

A study by the Society of Automotive Engineers found that using start-stop can see a car’s fuel economy improve by over eight percent in heavy traffic. That might not sound like a lot, but over time, it adds up to a whole lot of wasted gas.
