Kylmä marraskuu

Osoittaa, että tällä vuosituhannella on jatkuvasti ollut lämpimämpää kuin aiemmin (ja yksi kuukausi tuskin tarkoittaa, että suuri muutos on tapahtunut):

"The temperature anomaly was -0.014 °C. It means that the whole month was actually cooler than the the average recorded November. It was the first month in this century that was cooler than average."

Ja myös syyt marraskuun kylmyyteen annetaan:

"The previous record low temperature anomaly in this century occurred in July 2004 when the anomaly was 0.053 °C. In other words, the record low for this century was improved by 0.07 °C. The continuing La Nina is the main reason behind the recent cold months; La Nina is expected to disappear in Spring 2008. January 2000, a month that was even cooler than November 2007, witnessed a La Nina, too. November 2007 was also a whopping 0.915 °C colder than April 1998."

"Another reason could be an inactive Sun. We are expecting the solar cycle 24 to begin soon but it takes a longer time than expected and there are still almost no sun spots. Via a crucial mechanism, it means that we should be getting more galactic cosmic rays that should create more clouds."
