Carbon Dioxide Concentration in the Atmosphere

I regularly look at atmospheric carbon dioxide concentration even though it is invariably bad news. in the past twelve months CO2 in the atmosphere has risen to 408.53 ppm, which is a rise of 2.53 parts per million compared with 12 months ago. It seems relatively clear to me that this is shown in the extent of sea ice in the Arctic and the extent of ice in the Antarctic, both of which are reducing and in very modest sea level rises.

I think that now it is not about reducing the amount of carbon dioxide that humans push into the air, but about removing carbon dioxide from the air. It is not about targets, which as one commentator pointed out on these posts are usually politically motivated boasts but about hard measures of which there are insufficient around.

Does Anyone Care

Those who measure atmospheric concentrations of carbon dioxide are finding that in April their measurements show the highest ever readings. This seems to be reflected in global heat. February 2016 was the warmest month ever in 137 – years of record keeping. This is the tenth consecutive month that the monthly temperature record has been broken.  Continue reading

2015 – The warmest year on record?

Many eminent scientists confidently expect that 2015 will be the warmest year that humans have recorded. 2014 was previously the warmest year. The so called pause in global warming has been illusory. Continue reading

The times they are a changing

I was annoyed to read that some scientists had reported that in future the British Isles will have longer bursts of heat waves and be warmer, as a result of global warming. The story was widely reported. I am sure, as far as I can be, that global warming is taking place and that the climate of these islands will be different in future from its present climate, but I do understand that when predicting the future there are literally more things in heaven and earth than are dreamt of in our science.

The Long Run

In Karachi and the surrounding areas of Pakistan many people are suffering from heat exhaustion and some are dead as a result of very high summer temperatures. Karachi is a city of some twenty million inhabitants. It has poor infrastructural services – electricity is in short supply and clean water is short in summer- and this makes life almost unlivable when temperatures reach 45 Centigrade, as they have recently. The record temperature recorded at Karachi is 47 degrees Centigrade, which it hit in 1979. This is not a pleasant start to Ramadan. Continue reading

Atmospheric Carbon Dioxide Increases

In April 2015 the US measuring station at Mona Loa in Hawaii measured 403.26 parts of carbon dioxide per million in the atmosphere compared with 401.29 ppm in April 2014. The US National Oceanic and Atmospheric Administration state that world atmospheric carbon dioxide levels exceeded 400 ppm across the whole of the earth. The statement is based upon only 40 measuring sites, so it may be inaccurate, but for the first time all 40 sites reported measurements in excess of 400 ppm. Continue reading

Irrelevant Promises

Both the United States of America and the European Union have promised to cut carbon dioxide emissions by between 26% and 28% compared with what they emitted ten years ago. The promised emission reduction takes effect from 2015, ten years from now.  Continue reading
