February Temperature

The February 2016 land and ocean temperature anomaly was 1.35°C (2.43°F) above the average temperature in the period from 1951 to 1980, as above image shows (Robinson projection). On land, it was 1.68°C (3.02°F) warmer in February 2016, compared to 1951-1980, as the image below shows (polar projection). The image below combines the above two figures in two graphs, showing temperature anomalies over the past two decades. Below are the full graphs for both the land-ocean data and the land-only data. Anomalies on land during the period 1890-1910 were 0.61°C lower compared to the period from 1951 to 1980, which is used as a reference to calculate anomalies. The blue line shows land-ocean data, while the red line shows data from stations on land only. At the Paris Agreement, nations committed to strengthen the global response to the threat of climate change by holding the increase in the global average temperature to well below 2°C above pre-industrial levels and to pursue efforts to limit

Interview with Paul Beckwith

1) Hi Paul. Thanks for agreeing to do this interview. First of all, could you tell us a bit about your background, how long you’ve been involved in climate science, and what areas of climatology you specialize in? Hello Sam. Thank you. It is my pleasure to have this interview with you. I am an Engineer with a Bachelor of Engineering Degree in Engineering Physics (often called Engineering Science) from McMaster University in Hamilton, Ontario, Canada. I finished at the top of my class and received many scholarships and awards during my studies. My CV can be found on my website under the About Me section. I am a Physicist with a Master of Science Degree in Laser Physics. My research area was blowing molecules apart with high-powered CO2 lasers and measuring all the chunks flying off with low-power tunable diode lasers. This involved the science of molecular spectroscopy in the infrared region. I worked in industry for many years, as a Product Line Manager for opt

Ten Degrees Warmer In A Decade?

In 2015, mean global carbon dioxide grew by 3.09 parts per million (ppm), more than in any year since the record started in 1959. An added polynomial trendline points at a growth of 5 ppm by 2026 (a decade from now) and of 6 ppm by 2029. NOAA data , added trend points at 5 ppm growth a decade from now There are a number of elements that determine how much the total temperature rise will be, say, a decade from now: Rise 1900-2016: In January 2016, it was 1.92°C (3.46°F) warmer on land than in January 1890-1910, as discussed in an earlier post that also featured the image below. Rise before 1900: Before 1900, temperature  had already risen by ~0.3°C (0.54°F) , as Dr. Michael Mann points out. Rise 2016-2026: The image at the top shows a trend pointing at 5 ppm growth a decade from now. If levels of carbon dioxide and further greenhouse gases keep rising, then that will account for additional warming over the next ten years. Even with dramatic cuts in carbon dioxide emissions, tempera
