Climate change is not weather, which most people don't understand. Climate change leads to disruptions in normal patterns and creates extremes - both hot and cold - and this latest cold snap in Bolivia was well outside the bounds of historic norms and led to countless animal deaths - article here
The years-long solar minimum reduced the sun's output of energy and temporarily slowed Earth's global warming. Last year the sun had no sunspot activity (decreased solar energy output) 71% of the time, and this year the numbers reversed to 17% ... but today the sunspot number spiked up to 54 and spotless days decreased down to 16%. This is the day we transition into heightened sunspot activity, due to peak in mid-2013 if historic norms are met. By mid-2013 even the most self-interested climate-change deniers will no longer be able to sell their lies.
