Hot or Not Hot?

Which of the following two statements is true?

  • There has been no significant rise in global surface temperature since 1998.
  • The 10 warmest years on record have all occurred between 1997 and 2008.

There are two apparently competing claims of what is happening to global temperature. The more common claim is that recent years have been the warmest. This is often used by those who say that global temperatures are rising primarily due to the effects of increased concentrations of carbon dioxide produced by man in the Earth’s atmosphere. Others, who see global temperatures as more impacted by solar influences, say that global temperature trends for the last several years have stopped rising and, in fact, have been dropping.

So, back to the question; which of the statements is true?

Actually, it appears that both are true.

On each figure, temperature anomaly is the departure in temperature from the 1951 – 1980 base period averaged global temperature. With solar activity continuing to be very low, what will be the trend of future global temperature?

  • The people in the Maldives and Kiribati hope that things will cool off a bit. They're only a couple of meters above sea level. But they're not taking any chances:

    Jean – Cooling off a little would be good. Warming up further for islands like this won’t be.

    Barbara – Thanks! I’m going to try to post somewhat regularly and try to demystify some the hype that’s in the media. I’ve been reading quite a bit beyond what we see and hear in the news.

    The Global Warming Alarmists can explain all this.

    If it's warmer than usual, it's because mankind is generating greenhouse gases, causing the planet to heat up.

    If it's cooler than usual, it's because mankind is generating greenhouse gases, causing the planet to heat up, which leads to wild fluctuations in temperature. 😉

    PS. I really LIKE your new blog. It's a refreshing change from the same-old same-old stuff that's out there.
