I have heard that the feces of a cat has a stronger odor than that of other animals. Is this correct, and if so, I would be grateful if a user could please let me know the reason for this. Thank you. Simonschaim ( talk) 10:30, 15 March 2016 (UTC)

There is a map going around at sites like [6] showing a single color for "4 to 11.5" degrees Celsius above average for February. Where was the +11.5 C? Is there a way to see a map with contours for +6, +8, +10? Note: I think I found the raw data at GIST here, and one of the locations is in northern Russia south of the Kara Sea; maybe I should write a script to get an overall view but it would be more reassuring to see a real source. I don't see any option to adjust contours on their main map.
Bonus question: if methane clathrates or methane in permafrost were being released, would the effect be localized and viewable on such a map?
On a related note, the Severnaya mine explosion in Vorkuta, Komi Republic where 38 miners were killed by a series of methane explosions prior to February 28 is at 67N 59E, with a temperature anomaly of +10.98 degrees C. Has the remarkable weather been considered as a cause of this tragedy? Wnt ( talk) 11:41, 15 March 2016 (UTC)
@ SemanticMantis and Carbon Caryatid: For future reference, this amateur-hour Python script produces custom plots of the temperature from the primary data linked above (open them in a web browser): [Note that data is available from other months and years, but you have to go back and put settings into the page that draws their map to get it, because I used a tmp link] (oh, most of those libraries are unneeded; this was repurposed from part of an earlier program)
# -*- coding: utf-8 -*- import os, re, random, hashlib, hmac, logging, json, time file_base = os.path.dirname(__file__) input_loc = os.path.join(file_base, 'input.txt') output_loc = os.path.join(file_base, 'output.html') try: output_file = open(output_loc,'w') except: sys.exit('Failed to open output.txt in program directory') try: input_file = open(input_loc,'r') except: sys.exit('Input file input.txt not found in program directory') try: # do stuff with output_file print ('reading: ', input_loc, '\n') snarf = input_file.read() # this should be a short file! print (len(snarf), ' characters read\n') snarftable = snarf.split('\n') output_file.write ('<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN"\n"http://www.w3.org/TR/html4/strict.dtd">') output_file.write ('<html lang="en">\n<head>\n<meta http-equiv="content-type" content="text/html; charset=utf-8">') output_file.write ('<title>graph: ' + snarftable[0] + '</title>\n</head>\n<body>\n') output_file.write ('<div style="position:relative;"><div style="position:absolute;overflow:visible;') output_file.write ('top:30px;left:50px;background-color:#ffffff;border:1px solid black;height:1px;width:1px;">') print (len(snarftable), ' fields read\n') for x in snarftable: x = re.findall('\-?\d+\.?\d*',x) #This does not savvy ".5", etc. if (x): for i in range(len(x)): x[i] = float(x[i]) if (len(x)>4): lon = x[2] lat = x[3] color = int(round((x[4] + 2)*256/14)) if color < 0: color = 0 if color > 255: color = 255 color = str(hex(color))[2:4] if (len(color) == 1): color = "0" + color color = color + "0000" # convert to 000000 to FF0000 xpos = round((180 + lon)*512/180) # 1024 pixels wide ypos = round((90 - lat)*512/180) # 512 pixels deep - simple equirectangular projection! output_file.write('<div style="position:absolute;left:' + str(xpos) + 'px;top:') output_file.write(str(ypos) + 'px;width:6px;height:6px;background-color:#' + color + ';"></div>') output_file.write('\n') output_file.write ('</body>\n</html>') finally: output_file.close()
The result shows a focus of warm air all over Russia, radiating out from the area I mentioned above. However, the preceding months are very different, with lesser warming in the far north over the Arctic. Wnt ( talk) 18:34, 24 March 2016 (UTC)
When an experiment need cocaine, for example, for testing the preferences of mice given free sex, free sugar, or free cocaine, where do they get the cocaine from?-- Scicurious ( talk) 16:00, 15 March 2016 (UTC)
My scooter (a Yamaha Vity 125) cranks but won't start. Assuming the battery is flat, I've asked a friend to jump start it with me tomorrow morning. If that works, how long should I run the engine to get a good charge back in, and is it better to do that idling or riding around?
This happened after I left the scooter parked for nearly a month in cold weather, under a carport. The lights were off. Do batteries normally go flat in those conditions, or should I replace it? 94.194.199.193 ( talk) 22:57, 15 March 2016 (UTC)
