Yes Tom, there was much hyperbolie in relation to the Paris deliberations; but, politicians from various nations do not seem to understand the seriousness of anthropogenic climate change.
And yes, climate does change naturally as well; except, we have given it a mighty big wack.

2015 is about to be the warmest year on record; climate has come out firing in the last week or so of December. At the beginning of December it was already predicted that 2015 would be the warmest year.
Slightly less than 5 degrees South of the North Pole in the dark of winter a buoy measured temperature to be +1C .
"Buoy 300234062785480 located at 85.45N rose 25C in 9 hours (and is now above freezing). It was -24.3C at 0600 hours (day 363.25) and +1.0C at 1500 hours (day 363.626). "

At Svalbard they have measured positive temperatures for a week instead of negative ones, they even had some rain. Ski fields in Europe had very little snow or none in December.
In relation to Britain and US, the term "atmospheric rivers" has been used; warmth, is necessary to produce evaporation.

Wild fires and drought have an impact on climate; firies say that from their point of view climate change is real. There have been severe wildfires in the Northern Hemisphere ranging from Siberia, Alaska, California; and the Amazon Basin and Indonesia have had huge fires as well.
The results from drought can have a big impact on the health of trees and ultimately the water cycle. Although, not stated in reference below, a similar situation to the impact of wild fires and set fires on the health of trees. Indonesia and partly the Amazon Basin have been impacted by set fires.

.The ARM 11 year study has shown how radiated infrared long waves interact with CO2.
While the amount of energy per square meter may seem very small, the number of square meters surrounding the planet is mind boggling.

While the stated aim is to try and keep temperature increase at no more than 1.5C; there are only two chances of this happening, buckleys and none.
The economy at present doesn't take into account the impacts of climate change; deaths, health problems, loss of infrastructure, loss of houses, loss of vehicles, loss of personal possessions, nor does it take into account the subsidies provided to fossil fuel companies.

Twenty years to late, to much stop start, politicians with no idea or other agendas. We are in for one rough ride.

The problem here is vested interest and the power they exert over "leaders".

The fossil fuel industry reaps in over 4 trillion plus per, and will not surrender that income ever, even if that is what is required to guarantee a future for our grandchildren.

Just look at the crazy mess we've made of our world, where some of us are clearly obsessed with becoming the richest men in the graveyard!

Simply put, decarbonizing the economy is the most sensible thing we can ever do, and on hard cold staring you in the face, factual economic grounds.

If the fossil fuel industry would get on board and lead, with viable alternatives? Our problems and theirs would dissolve overnight, almost as if they'd never existed!?Alternatively our so called leaders to grow some testicals and buck the power of these controlling forces; and just get on and do what we pay them for, their jobs!

And if we could just stop the con artists from the usual confidence trickery, we would abandon such things as a carbon market and the huge fees that would generate for a greedy few, who would if they could make carbon the most valuable, most traded commodity in the world and see the world following Germany's insane (the lunatics have taken over the asylum) example and shut down the nuclear industry, in favor of new coal fired power plants!

We need to tell our leaders thus far and no further, and use the ballot box to remove the intransigent recalcitrants, the denialists, the fossil fuel yes men and those who believe they control us.

And make that incredibly obvious by continuing to hold out on a bill of rights, which would devolve power from them to us! Enough with the yes buts and endless excuses already.
Rhrosty.

Shorten and Turnbull's global warming policies are all talk. Politically they cannot implement most of their statements/goals.

All leaders and countries rely on economic growth (non-renewable energy growth).

Most energy use/pollution increase discussions center on electrical energy production for fixed properties (homes, offices, factories etc). But it is the increase in petrol using car/truck numbers that is making a big impact in India and China.

Political popularity and economic health rely on economic growth. This is especially true in the main energy users that matter China, India and the US.

Pollution reduction are major needs in China and India but only rich developed countries, like the US, can afford pollution reduction.

Immigration of rich Indian and Chinese to Australia (with Real Estate increases) is a cert and economic benefit for Australia.

Given that the major problem, out of control population growth, was never mentioned, nothing was indeed done or achieved.
