Judging by the curves that have been created from all the data world wide it reminds me of a forwards biased diode.
A period of little or no change within limits as EMF is applied, which then hits a knee as said limit is exceeded that heads towards meltdown rapidly as more EMF is applied, culminating into total destruction once a certain PD is reached across its two _poles_.
That looks like our planet's demise except instead of EMF/PD we are looking at Degrees Celsius/Centigrade and gaseous materials that retain heat as they absorb heat radiation. The sad fact is that those _black_body_ gases are being generated in large quantities by man by many various means.
Nature is also playing its part too so the aggregate becomes a dangerous combined quantity.
It is not looking too good for advanced lifeforms on this tiny blue pebble we live on but I suspect amoebae and bacteria will survive and start evolution all over again.
That is until this little blue pebble is absorbed by an expanding sun in around 4 Billion, (short scale), years time.

vlimit
vlimit(3) Library Functions Manual vlimit(3)
Name
vlimit - control maximum system resource consumption
Syntax
#include <sys/vlimit.h>
vlimit(resource, value)
Description
This facility has been superseded by
Limits the consumption by the current process and each process it creates to not individually exceed value on the specified resource. If
value is specified as -1, then the current limit is returned and the limit is unchanged. The resources which are currently controllable
are:
LIM_NORAISE Pseudo-limit; if set nonzero then the limits may not be raised. Only the super-user may remove the noraise restriction.
LIM_CPU The maximum number of cpu-seconds to be used by each process.
LIM_FSIZE The largest single file which can be created.
LIM_DATA The maximum growth of the data+stack region via beyond the end of the program text.
LIM_STACK The maximum size of the automatically-extended stack region.
LIM_CORE the size of the largest core dump that will be created.
LIM_MAXRSS a soft limit for the amount of physical memory (in bytes) to be given to the program. If memory is tight, the system will
prefer to take memory from processes which are exceeding their declared LIM_MAXRSS.
Because this information is stored in the per-process information this system call must be executed directly by the shell if it is to
affect all future processes created by the shell; limit is thus a built-in command to
The system refuses to extend the data or stack space when the limits would be exceeded in the normal way. A break call fails if the data
space limit is reached, or the process is killed when the stack limit is reached. Since the stack cannot be extended, there is no way to
send a signal.
A file I/O operation which would create a file which is too large will cause a signal SIGXFSZ to be generated, this normally terminates the
process, but may be caught. When the cpu time limit is exceeded, a signal SIGXCPU is sent to the offending process; to allow it time to
process the signal it is given 5 seconds grace by raising the cpu time limit.
Restrictions
If LIM_NORAISE is set, then no grace should be given when the CPU time limit is exceeded.
