A real thing, fueled by scare tactics, and empowered with an agenda to sell more things. |
Eh. I would be happy to defend the conversion to solar (and other renewables) over non-renewables even on the reasonable probability that climate change were a hoax. But sure, there is some hot air and alarmism ('scare tactics') out there. |

Christie claims Trump wants to purge the EPA
| Quote: |
Christie also told the gathering that changing the leadership of the Environmental Protection Agency, long a target of Republicans concerned about over regulation, would be a top priority for Trump should he win in November.
Trump has previously vowed to eliminate the EPA and roll back some of America's most ambitious environmental policies, actions that he says would revive the U.S. oil and coal industries and bolster national security.
Christie added that the Trump team wants to let businesspeople serve in government part time without having to give up their jobs in the private sector. |

Mod Edit. If Trump loses, Christie's political career will thankfully be adios. |

Scientists are starting to clear up one of the biggest controversies in climate science
| Quote: |
[A] growing body of research [] suggests that warming estimates made from the historical record alone are “potentially biased low, for reasons we are now just beginning to understand,” said Timothy Andrews, a climate scientist with the Met Office, the United Kingdom’s national weather service, in an email to The Washington Post. While Andrews was not involved with the new study, he’s one of multiple scientists whose recent research has tackled the same issue.
The new study uses a statistical method to separate “fast” and “slow” climate modes in the models. According to Proistosescu, when greenhouse gases are emitted into the atmosphere, a “fast” warming effect begins to take place almost immediately in certain parts of the planet, mainly over the land masses in the Northern Hemisphere. Indeed, these are the parts of Earth where the most rapid warming has been observed since the Industrial Revolution.
On the other hand, he said, other parts of the planet — namely, the Southern Ocean and the eastern Pacific — respond much more slowly, in part because they’re just so deep and cold to begin with. But as they absorb more heat and finally start to warm up, they may produce a variety of climate feedback effects that enhance the global warming that’s already occurring. For instance, changes in ocean temperatures can alter atmospheric patterns around the world. The models suggest that these warming ocean regions may lead to a decrease in reflective cloud cover in the future, allowing more solar radiation to make it through the atmosphere to Earth’s surface.
While the impact of these processes may be profound, they can also take long periods of time to unfold, Proistosescu said — potentially up to 300 years or so. Through their statistical parsing, the researchers found that the models suggest the effects of this slow climate mode only account for about 3 percent of the human-caused warming we’ve seen so far. But in the future, under a scenario in which atmospheric carbon dioxide concentrations double, it could account for up to half of all warming that occurs.
Since they were able to separate the fast and slow climate modes, the researchers also conducted a test to see what would happen if they only applied fast climate warming in the models. When they did so, the model predictions suddenly fell in line with the historical record — suggesting that the still-developing slow mode is the reason the two have failed to match so far. |
