The vast majority of educated scientists agree that climate change is real and will only get worse if nothing is done to at least slow it down.

The current drought affecting parts of the country are exacerbated by land clearing (trees transpire water to the atmosphere which facilitates cloud formation thus causing rain) but our state government has permitted a huge increase in clear felling.

I went to uni in the late 60s, and back then people were talking about 'global warming' as a future problem. That problem is here today, and it is going to have a far greater impact on younger generations than it will on Mr Ernst and mine.

I would ask John what his qualifications are to make the statements he does. I have a Bachelor of Science , a BSc in Education. and a Certificate 4 in horticulture. Show us what you've got John.

At last voters get a say on whether Scott Morrison should continue to lead our nation backwards.

His pitch this morning gave voters more of the he same historical fiction about how "his government" had created a "strong economy, lots of jobs (evidence please?) and kept us safe (from what?) and that success for us rests solely on the economy.

I am really hopeful that voters will, at last, consider voting for parties who want to build a fair, strong and healthy society, preserve and protect our environment from rapacious corporations and ensure workers are provided with safe workplaces and decent wages.

News for you Scott we are now in the 21st century and we expect our governments to lead us forward to a better future for our children and grandchildren.

In December last year i attended the Wollongong and Port Kembla hospitals for surgery and rehab on my right knee. Returning home on the eve of December carelessness on my part several days later in falling at home caused serious damage to the injured leg.

Surgery and hospitalisation over a period at Wollongong, Bulli and Port Kembla followed. Finally I arrived home three months later for continual rehab.

I wish to take the opportunity through the Mercury letters to offer my thanks and appreciation for the outstanding attention to detail with my medical procedure and ultimate rehab.

I do not wish to name folks, they know who they are. but from the senior medical operation team to the young man who mops the floor, stand up and take a bow. You are angels.

At all times you went far and beyond the call of duty. You do a job that many would not be able to handle. You all have given me the degree of strength and confidence in my near 79 years that I have not felt before, to continue on.

Thank you once again and keep the flag flying through the medical system in the illawarra.
