But more than 7% of deaths are related to cold—counting hypothermia, as well as increased blood pressure and risk of heart attack that results when the body restricts blood flow in response to frigid temperatures.”
High blood pressure is estimated to account for approximately 13% of CVD deaths, while tobacco accounts for 9%, diabetes 6%, lack of exercise 6% and obesity 5%.

However, studies have determined that current technology is sufficient to reduce greenhouse gas emissions the necessary amount, and that we can do so without significant impact on the economy.
Economists generally argue that carbon taxes are the most efficient and effective way to curb climate change, with the least adverse effects on the economy.

Correspondingly, the global surface temperature has also dropped."
These isotope changes occurred due to the release of carbon from the ocean into the atmosphere that led to a temperature increase of 4-8 °C (7-14 °F) at the surface of the ocean.

global warming ceased around the end of the twentieth century and was followed (since 1997) by 19 years of stable temperature.
The average global temperature on Earth has increased by about 0.8° Celsius (1.4° Fahrenheit) since 1880; Two-thirds of the warming has occurred since 1975, at a rate of roughly 0.15-0.20 °C per decade.

Electricity rates are 40 percent higher in states that have required utility companies to use a certain amount of renewable energy such as solar power.
Smart grid technology is a necessary condition for very large amounts of renewable electricity on the grid for this reason.
