And thus the battle you can't win on any significant level IMHO. The reality won't affect the vast majority of the people won't have to face the reality because the reality is several generations away. And those generations have no vote today. I don't consider it a defeatist attitude to accept that which one has no chance of changing.
This is where a lot of people get confused by the nay sayers and delayers. Climate change is happening now, not in some distant future. People won't wake up on New Years Day 2100 with 1.5 - 6.5 degrees of warmer temperatures and 3 ft. of ocean all of a sudden lapping at their door step. A growing magnitude of climate related problems that threaten humans will be happening all along the way till then and several centuries into the future beyond.

Talk about cognitive dissonance.
if we're left with our pants down? That's where it really gets ugly
The Intergovernmental Panel on Climate Change’s (IPCC) Fifth Assessment Report (AR5) has delivered an overwhelming consensus that climate change impacts are accelerating, fueled by human-caused emissions. We may have just about 30 years left until the world’s carbon budget is spent if we want a likely chance of limiting warming to 2 degrees C. Breaching this limit would put the world at increased risk of forest fires, coral bleaching, higher sea level rise, and other dangerous impacts.
When Will Our Carbon Budget Run Out?
The international community has adopted a goal for global warming not to rise above 2°C compared to pre-industrial temperatures. Scientists have devoted considerable effort to understanding what magnitude of emissions reductions are necessary to limit warming to this level, as the world faces increasingly dangerous climate change impacts with every degree of warming (see Box 1).
IPCC AR5 summarizes the scientific literature and estimates that cumulative carbon dioxide emissions related to human activities need to be limited to 1 trillion tonnes C (1000 PgC) since the beginning of the industrial revolution if we are to have a likely chance of limiting warming to 2°C. This is “our carbon budget” – the same concept as a checking account. When we’ve spent it all, there’s no more money (and the planet’s overdraft fees will be much more significant than a bank’s small charges for bounced checks).1
The report also states that as of 2011, we have emitted roughly 531 PgC since the industrial revolution, meaning we have already burned through about 53 percent of that carbon budget.
Do the math, and the world only has 469 PgC left in the budget. This balance puts us on track to exhaust our remaining carbon budget before the end of 2044 under a carbon intensive trajectory.2
I also see that some extreme events are now becoming statistically relevant, with an assessment that CO2 rise has likely (66 to 100 percent probability) more than doubled the probability of heat waves in some places.
Both policy and the IPCC should change course: More of the same is not likely to improve the response to climate change. More strategic approaches might help. The focus should change from bulky, comprehensive studies to deeper, more facile efforts targeted at phenomena and impacts that are poorly understood and could become critical. Feedback mechanisms, the role of aerosols and clouds, sea level rise, droughts, floods, and heat waves, etc., all deserve focused attention and the most up-to-date assessment. Such studies can shine a light on what keeps climate scientists up at night and hopefully keep the politicians awake as well. Second, the currently failing strategy of negotiating incremental emission caps should be replaced with a strategy for reinventing the energy system without emissions as fast as possible. Every region should create strategic plans for eliminating emissions as fast as they can.
The new report shows that there is now a veritable hockey league of reconstructions that not only confirms, but extends, the original hockey stick conclusions. The message of the latest IPCC report is clear: Climate change is real and caused by humans, and we will see far more dangerous and potentially irreversible impacts if we do not reduce global carbon emissions. There has never been a greater urgency to act than there is now.
...the risks from changes in hurricanes, tornadoes, and droughts are understated. Literature published or submitted since the working group’s acceptance date of March 15, 2013 adds information on all of these topics and highlights the conservative nature of the IPCC report.
Methane now has a more dominant role via its impact on atmospheric chemistry, and other, more traditional pollutants are included that show clearly the connections between air quality and climate.
The IPCC working group did not ... provide a risk assessment of future climate change impacts...In the case of sea level...it is the worst case that is relevant
to stand a good chance (a probability of 66 percent or more) of limiting warming to less than 2°C since the mid-19th century will require cumulative CO2 emissions from all anthropogenic sources to stay under 800 gigatons of carbon. As of 2011, 531 gigatons had already been emitted.

"Vietnam (AP) — Vo Nguyen Giap, the brilliant and ruthless self-taught general who drove the French out of Vietnam to free it from colonial rule and later forced the Americans to abandon their grueling effort to save the country from communism, has died. At age 102, he was the last of Vietnam's old-guard revolutionaries. Giap was a national hero whose legacy was second only to that of his mentor, founding President Ho Chi Minh, who led the country to independence.
The so-called "red Napoleon" stood out as the leader of a ragtag army of guerrillas who wore sandals made of car tires and lugged their artillery piece by piece over mountains to encircle and crush the French army at Dien Bien Phu in 1954. The unlikely victory, which is still studied at military schools, led not only to Vietnam's independence but hastened the collapse of colonialism across Indochina and beyond. Giap went on to defeat the U.S.-backed South Vietnam government in April 1975, reuniting a country that had been split into communist and noncommunist states. He regularly accepted heavy combat losses to achieve his goals."
