This has been a month of superlatives. Firstly, the number of dengue cases crossed the 10,000 mark for the year and is likely to surpass 15,000 by year’s end. Chikungunya
, unheard of in Singapore 7 years ago, is now fairly common.
Now, PSI reading on haze caused by the Indons surpassed 400; hazardous level, totally unprecedented. I wonder if there is any upside of the haze on aedes mosquitoes?
Note: Earlier this month, the Mauna Loa Observatory in Hawaii has reportedly recorded a carbon dioxide concentration there of 400 parts per million for the first time. One hundred years ago, levels had risen to around 300, and then surpassed 350 in the late 1980s.
