Thermometer

Let us record here scientific papers on AGW, record happenings in the Arctic, Greenland, the Himalayan ice sheet and Antarctica. Also weatherstorms and higher than average rainfalls

Global monthly temperature for July 2017 was equal with global temperature for July 2016—yet 2016 was an El Nino year and 2017 was not. Now I see that August 2017 was warmer than August 2016. What can I say but WOW!

Global temperatures for Aug 2017:

Looking at the image you can see:

1. There is a clear overall trend upwards

2. The winters have warmed significantly—no wonder polar sea ice is disappearing and land based ice sheets are sliding into the sea!

3. You can see the trend even tho there is some mixing, some 1880 readings being higher than 1900 readings and most of the bands you see temperatures from earlier. Weather is an incredibly noisy record and there are lots of sources of variation including the ENSO cycle El Nino-Neutral-La Nina etc. The Pacific Decadal Oscillation is a multi-decade long source of variation. But the warming trend is clear.

Will we hold warming to 2°C? Nope. Fossil fuel interests are too powerful, too rich a lobbying group.

What will happen is flooding on a huge scale not seen before on the US East Coast due to rising sea levels and THEN we might get serious about reducing emissions and removing CO2 from the atmosphere.

There is another aspect of AGW that you can see in the chart: spring starting earlier each year, causing problems for migratory birds. Look at the graph and imagine a vertical line on 1 March until it hits the blue band, the 1880 temperatures. From that point imagine a horizontal line Mar-Feb-Jan. You can see the sort of temperatures in spring in the late 1800s is now reached mid Jan. In Britain spring has advanced by 11 days.

Why does this cause problems? Because there is the matter of sunlight, increasing day lengths as well as increasing temperatures signal to plants that it is spring. Now the signal is mixed, birds arrive when there is not yet any food for them.
