The increased ice flow was caused by a warmer temperature that year, sure.  That doesn't mean the warmer temperature was global warming, it may have just been a heat cycle.  Even climate change advocates say that the temperature has only risen an average of about 2 degrees worldwide in the last couple decades, which is clearly not enough to cause a ship-sinking ice flow.

Yeah, and the Global Temprature dropped two degrees last year after it was doing so well. I wish they would stop fooling with the numbers because now after 25 years of global warming we are now being told that we are going into an ice age that will hit us in the next 30,000 years, wait a minute, 30 years ago we were all going to die from the coming ice age if we did not warm up the planet, this is the same cycle that the NYT wrote about in the 1800's and if you look back far enough you will see that we have been getting warmer and colder on 25 to 30 year cycles since we have been recording local tempratures. Anyone remember reading about the Blizzard of 1949 in school? The coldest winter in recorded memory? This sounds strange that no one picked up on this yet, well, except for climatologist, NASA, and anyone that remembers High School science.

Sort of crazy in hind sight. Keep in mind that the California was twenty miles ahead of where the Titanic struck the ice and was in the middle of the ice flow and stopped for the night. The Carpathia was fifty miles behind the Titanic and traveling slowy because of ice. Between the two the area was clear of ice. Thats seventy or eighty miles of calm flat sea with no known reports of ice. Add to that the desire of the owners to beat their sister ship Olympic on the transatlantic run. One of the owners was on board at the time so there was a lot of pressure to make history. They did, just not the kind they expected.

There were so many factors that lead to the sinking of Titanic that you can't really pin it on one cause. If I may give you some examples.

There was no accurate way to track the ice flows back then, The only way to know there was ice was if someone spotted it and reported it. Someone had to hear the report and the average broadcast range of most radio sets at the time was 80 miles. Titanic had the newest Ship to Shore radio and could broadcast a little over thousand miles if weather conditions allowed and it was broken most of Saturday and Sunday. When I say broken I mean it could receive any message within range but could not send more than 80 miles.

The Steel used to build the ship was not mixed c.orrectly, too much sulfur, causing it to be more brittle in the cold water. 

The binoculars used by the lookouts was locked up and no one could find the key since they left port. The key was in someone's pocket back in the UK.

The Ship to Shore radio broke and the radio operators spent the better part of a day fixing it.

This caused a backlog of out going messages the operators were hired to send for the passengers and did not have time to pass six ice warnings up to the bridge. The last ice warning came around 5PM and the captain gave the course and speed for the night based on that warning. Captain Smith checked the conditons before going to bed around 10PM and made no changes, but left orders that if there were any changes in conditions to notify him immediately.

The Titanic had a very strong bow. If when they sighted the iceberg they had done the wrong thing such as hit it head on there is evidence that the ship would have survived. The evidence is sonar images taken of the bow at the bottom of the sea. It had hit the sea floor doing close to 56 miles an hour and though deformed was still intact.

There was also a problem with the rivets. Some were not as strong as they were supposed to be due to high sulfur content. From imaging, and testing back in the 90's it looks as though instead of a huge gash of three hundred feet the berg sheared off a few key rivets causing the hull plating to pop open letting in more water than if there were a gash. They did confirm a 22 foot gash on the side of the ship. 

There were enough lifeboats for 1200 or so people yet people were afraid to leave Titanic till it was too late. The first lifeboat could hold 63 people but only took 20 or so. I am doing this from memory so my numbers are not exact. Only the last few lifeboats went out full the rest were less than half full. So they could have saved 1200 or maybe even 1300 people instead only 705 survived.

Windy conditions that day caused them to suspend the lifeboad drill that was scheduled for Sundy the 14th. It was too cold to have the passengers out on the weather decks.

So yes, they were traveling fast but for the known conditions they were not reckless. We sit back 90 years later and ask how could they be so stupid! Looking at it from their point of view things were a little different.

This part was the thing that facinated me the most. The steam ship California got the blame for not responding to Titanic's SOS. It was said they sat and watched Titanic sink too afraid to go through the ice and save people. It was discovered in the early 90's that this was not true. In fact there was a ship that was between Titanic and California. A Norwiegen fishing vessle had been poaching and was heading home with its catch. The California saw that ship thinking it was Titanic, but Titanic was over the horizon, Titanic saw the ship and the only ship that was reported in the area was California so they got the blame. Only when ships logs were being transcribed to computer media did anyone find out about this other ship. It as ten miles from Titanic and when it saw the destress rockets and left the area for fear of being reported. Though smaller than Titanic they could have taken on most of the people that died that night for transfer to other ships later that day.

At the time it was not mandatory to have 24 hour radio operations, The California's one radio man went to sleep at 11PM 40 minutes before the Titanic struck the berg.

These examples are off the top of my head there are many more issues that sealed the fate of Titanic.

Remember that they hit a blackberg, it was spotted less than a mile away and the ship needed three miles to stop. If it were a normal berg that reflected light and was contrasted by the dark water then they would have spotted it sooner.

The reports of ice came in but not all the messages made it to the bridge or the captain. The list you gave of ice was from the radio log that survived so yes, they had the warnings but it is like your 18 year old kid takes a message from the bank saying that you are over drawan. The kid forgets to pass it on to you. Yes, you in the form of your family, legally received the message but you did not get the message. The radio operators reveived the messages, they loged them in, but they admitted in the inquiry that they were too busy to pass them on in a timely way. This was evidenced by the report from the Californian radio operator who testified that he tried to chat with Titanic before going to bed and the Titanic radio operator told him to shut up he was busy. The ice warning was passed to Titanic but never reached the bridge. As far as the ships leadership knew all the ice was behind them. Captian Smith did get all the ice messages 20 minutes after the collision.

This is what I meant by we are using hindsight to judge a contemporainous situation. Captian Smith was on his last voyage before retirement. He was very experienced with 20 plus years at sea and the senior captian of the White Star Fleet. I find it very hard to believe that he ignored ice warnings or allowed his ship to sail in dangerous conditions.

Recklessness would be the sinking of the Andria Doria, they were traveling too fast for the foggy conditions, the radar operators had the wrong settings on both ships. Both ships failed to communicate properly with each other.

With Titanic there was one lone berg on the outer edge of an ice flow that was as dark as night. When Titanic stopped it was still 20 miles from the edge of the ice flow and the Californian. The Norwigian fishing ship was between them and still sailing.

In hindsight they should have slowed or stopped till morning, experience and conventional wisdom says that once you turn the corner and head west you should be clear of the ice. Captain Smith had gone much further south just to avoid the ice before he turned the corner that afternoon. (turning the corner was the term used at the time when the ships head south and then west from the European continent. It was believed that once you turned the corner you were safe from ice.) Conventional wisdom was wrong in this case.
