World Temperature Trends


Is the world's average temperature warming? Yes, it is.
Here is a chart I have made with the R programme from the NASA Goddard Institute for Space Studies data.

The data is the Combined Land-Surface Air and Sea-Surface Water Temperature Anomalies (Land-Ocean Temperature Index, LOTI), Global-mean monthly, seasonal, and annual means, 1880-present

The chart is a line plot of differences in annual land-ocean average temperature from the average for the base period 1951-1980 global mean temperature index, 1880 to present. The dotted blue line is the annual mean and the solid red line is the five-year mean, calculated with a Lowess function.

Powered by coal

Here's a CBS 60 minutes documentary featuring James Hansen and the CEO of Duke Energy, the USA's third largest coal thermal power plant owner. The CEO says he totally accepts that carbon dioxide contributes to global warming. However, his plan is to phase out coal over 40 years. CBS cut to Hansen who of course says "No new coal fired power plants and a phase out must take place in 20 years or less". CBS goes back to the CEO and ask him how much Duke has invested in carbon capture and sequestration. The answer is not a cent!

Jan Wright says leave the lignite

Dr Jan Wright, the Parliamentary Commissioner for the Environment has channeled her inner James Hansen into her latest report Lignite and Climate Change: The high cost of low grade coal.

She concludes that the lignite plans of NZ's state-owned coal miner, Solid Energy, will just exacerbate the gap between NZ's actual greenhouse gas emissions and our policy goals. She recommends that the Government (as shareholder) should instruct Solid Energy to withdraw their plans to develop the Southland lignite deposits.
