Jason Box at Dark Snow Project:
Sensors in Earth orbit give us the capability to monitor vast areas, daily, in near real-time. As part of the Dark Snow Project, I’ve been working with daily NASA MODIS MOD14A1 data to map the occurrence of fire activity. The map below illustrates the single most active day so far in 2015 for North America with fires ravaging central western Canada and interior Alaska.
Through 18 July, 2015, these data indicate the cumulative radiative power of North American fires to be the highest on record in the period of observations beginning in 2000. For July, 2015 fire power is 2.5 times the sixteen summer average 2000-2015.

Sobering statistics on an intense wildfire season, and I am wondering how much of the material has found its way up to Greenland, and how much the albedo has been affected during 2015.
On a totally different topic that intrigues me a lot .. I am wondering who told the Florida Institute of Technology that “Beyond 670 ppm – which represents a 3.5 degree Fahrenheit ocean temperature increase”
I understand it is significantly lower than that.

“In 2005 an international conference called “Avoiding Dangerous Climate Change: A Scientific Symposium on Stabilisation of Greenhouse Gases” examined the link between atmospheric greenhouse gas concentration, and the 2 °C (3.6 °F) ceiling on global warming thought necessary to avoid the most serious effects of global warming. Previously, this had generally been accepted as being 550 ppm”
“The conference concluded that, at the level of 550 ppm, it was likely that 2°C would be exceeded, according to the projections of more recent climate models. Stabilising greenhouse gas concentrations at 450 ppm would only result in a 50% likelihood of limiting global warming to 2 °C, and that it would be necessary to achieve stabilisation below 400 ppm to give a relatively high certainty of not exceeding 2 °C.”
