high temperatures or who
become physically active...» However, no supporting information on young adults was provided to confirm that this arbitrary figure was in any way justified.
In addition it is also effective in removing excess fat which can be explained
by the fact that fats
become water - soluble when they are exposed to the
temperature higher than 45 degrees Celsius (113 degrees Fahrenheit) thus forcing the body to eliminate the excess fat together with water during the process of sweating triggered
by sauna or another prolonged hot treatment such as hot foot bath, hot shower, etc..

Since 1950 the number of heat waves worldwide has increased, and heat waves have
become longer.5 The hottest days and nights have
become hotter and more frequent.6 7 In the past several years, the global area hit
by extremely unusual hot summertime
temperatures has increased 50 - fold.8 Over the contiguous United States, new record
high temperatures over the past decade have consistently outnumbered new record lows
by a ratio of 2:1.9 In 2012, the ratio for the year through June 18 stands at more than 9:1.10 Though this ratio is not expected to remain at that level for the rest of the year, it illustrates how unusual 2012 has been, and how these types of extremes are
becoming more likely.
Most climatologists believe that if
temperatures rise more than another 1 degree C
by 2100, conditions on the planet could
become radically different and disruptive, including sharp shifts in precipitation patterns, more severe storms and droughts, the disappearance of the Arctic ice cap in summer, Greenland ice sheet instability, and much
higher sea levels.
In light of trends showing a likely 3 °C or more global
temperature rise
by the end of this century (a figure that could
become much
higher if all feedback processes, such as changes of sea ice and water vapor, are taken into account) that could result in sea level rises ranging from 20 to 59 cm (again a conservative estimation), Hansen believes it is critical for scientists in the field to speak out about the consequences and rebuke the spin offered
by pundits who «have denigrated suggestions that business - as - usual greenhouse gas emissions may cause a sea level rise of the order of meters.»
And unless something like the hockey stick is known with
high confidence, it's hard to know what fraction of the
temperature trend assign to CO2, and then «supported
by temperature trends»
becomes a very iffy argument.
It went something like this: hotel check - in, locate room, locate wifi service, attempt connection to wifi, wonder why the connection is taking so long, try again, locate phone, call front desk, get told «the internet is broken for a while», decide to hot - spot the mobile phone because some emails really needed to be sent, go «la la la» about the roaming costs, locate iron, wonder why iron
temperature dial just spins around and around, swear as iron spews water instead of steam, find reading glasses, curse middle - aged need for reading glasses, realise iron
temperature dial is indecipherably in Chinese, decide ironing front of shirt is good enough when wearing jacket, order room service lunch, start shower, realise can't read impossible small toiletry bottle labels, damply retrieve glasses from near iron and successfully avoid shampooing hair with body lotion, change (into slightly damp shirt), retrieve glasses from shower, start teleconference, eat lunch, remember to mute phone, meet colleague in lobby at 1 pm, continue teleconference, get in taxi, endure 75 stop - start minutes to a inconveniently located client, watch unread emails climb over 150, continue to ignore roaming costs, regret tuna panini lunch choice as taxi warmth, stop - start juddering, jet - lag, guilt about unread emails and traffic fumes combine in a very unpleasant way, stumble out of over-warm taxi and almost catch hypothermia while trying to locate a very small client office in a very large anonymous business park, almost hug client with relief when they appear to escort us the last 50 metres, surprisingly have very positive client meeting (i.e. didn't throw up in the meeting), almost catch hypothermia again waiting for taxi which despite having two functioning GPS devices can't locate us on a main road, understand why as within 30 seconds we are almost rendered unconscious
by the in - car exhaust fumes, discover that the taxi ride back to the CBD is even slower and more juddering at peak hour (and no, that was not a carbon monoxide induced hallucination), rescheduled the second client from 5 pm to 5.30, to 6 pm and finally 6.30 pm, killed time
by drafting this guest blog (possibly carbon monoxide induced), watch unread emails climb
higher, exit taxi and inhale relatively fresher air from kamikaze motor scooters, enter office and grumpily work with client until 9 pm, decline client's gracious offer of expensive dinner, noting it is already midnight my time, observe client fail to correctly set office alarm and endure
high decibel «warning, warning» sounds that are clearly designed to send security rushing... soon... any second now... develop new form of nausea and headache from piercing, screeching, sounds - like - a-wailing-baby-please-please-make-it-stop-alarm, note the client is relishing the extra (free) time with us and is still talking about work, admire the client's ability to focus under extreme aural pressure, decide the client may be a little too work focussed, realise that I probably am too given I have just finished work at 9 pm... but then remember the 200 unread emails in my inbox and decide I can resolve that incongruency later (in a quieter space),
become sure that there are only two possibilities — there are no security staff or they are deaf — while my colleague frantically tries to call someone who knows what to do, conclude after three calls that no - one does, and then finally someone finally does and... it stops.
