Climate change

Climate change is real. However there are so many people, including politicians who run our country and world, who remain unconvinced about the reality of climate change.

"last summer was so cold. maybe global warming is not happening."
Independent records show that the earth's average surface temperatures have risen over the last century. The oceans have absorbed so much of the additional heat, which impact its underwater ecosystems. The global warming is recognised by NASA and CSIRO.
Also short term weather events are very different from long term climate trend. And the trends are there are more extreme weather patterns and warmer temperatures.The trends must be taken on a whole over larger areas, not from small regions.

"Global temperatures are supposed to fluctuate"
The earth does naturally cool and warm, but each time it happened in the past there have been natural causes instead of us humans causing the effects. We pump about 30 billion tonnes of CO2 into the atmosphere every year. As well as other greenhouse gases, such as methane, which is 25 times more potent than carbon dioxide.

"it's too late to do anything about it"
We are experiencing already the effects of climate change. However we can avert or at least make it less severe.
Our response as individuals, communities and nations is critical. every bit will count!
