Welcome, Analytica Friends,

The UN has received pledges for the Paris climate talks this December from member nations that produce 90% of global greenhouse gas emissions. Are these pledges fair? Could they keep the world below the UN's 2OC warming target?  In this issue Max Henrion, CEO at Lumina, uses Analytica to analyze the issues.

Read on to find out how to have fun with dates and meet the newest member of the Lumina team.

Do you have an idea for our newsletter? – I’d love to hear it.

Apples to Oranges to Chinese Gooseberries: Pledges for the Paris climate talks

This December UN member nations will meet in Paris to negotiate a new Climate Change Treaty. In preparation, most countries (representing about 90% of global greenhouse gas emissions) have pledged to reduce emissions, including 26 to 28% by the US; 30% by Canada, 40% by the EU, and 60 to 65% by China. Is the US proposal really as feeble as it appears? Countries use a wide variety of base years and metrics making them really hard to compare.

In his blog article, Apples to Oranges: Apples to Oranges to Chinese Gooseberries: Pledges for the Paris climate talks, Lumina CEO, Max Henrion uses Analytica to make these pledges directly comparable. He asks, “Are they fair?" and "Are they enough to keep global warming below the UN's avowed goal of  2OC?"
 


Tips & Tricks: Fun with dates by Lonnie Chrisman, CTO
November 25 of this year will mark my ten thousandth anniversary. That's how many days will have elapsed since my wife and I were married back in 1988. The fact that I know the number of days may have you conjuring a vision of me counting the days, like a prisoner etching a mark for each day in his cell wall, but thankfully that is not the case. I simply found this anniversary date in Analytica using the expression:
   9-Jul-1988 + 10K

I recently impressed my sister when I told her how many days old she was. She was certain I had spent a lot of time working that out. Little did she know it was a simple matter of subtraction. For example, Jeanne Calment, the oldest verified person to have ever lived, lived to be 44,724 days old:
   4-Aug-1997 - 21-Feb-1875

I've found that my personal models of stock market volatility and option valuation tended to fit the data better when I measure the number of weekdays elapsed between two dates, as opposed to the total number of days elapsed. The number of weekdays remaining on an options contract is:
   DatePart(expirationDate, 'wd')
        - DatePart(Today(), 'wd')
The 'wd' stands for "week days". As you type into Analytica, Expression Assist lists all the options, from year 'Y' to second 's'.
To generate a sequence of the next 100 weekdays:
   DateAdd(Today(), 0..99, 'wd')
Or a sequence of weekdays between two given dates:
   Sequence(date1, date2, dateUnit:'wd')
