Petaluma, Calif.: What do we actually know about climate change? If we are honest, we’ll admit that our knowledge is generally pretty spotty. Furthermore, the information we think is accurate might be coming from media sources and politicians who are being less than truthful in order to help their benefactors in the oil and energy industries.
But we do know that we love our children and grandchildren. Current climate science is clear that the extreme weather events we’ve seen in the last few years are just the beginning of a serious climate crisis. Do we want it on our conscience that we did nothing while extreme weather began to spiral out of control, becoming more and more devastating every decade — eventually leading, in various locales, to mega-hurricanes, repeated massive floods, unstoppable wildfires, unbearable heat waves, deadly tornadoes ripping up communities, droughts shriveling up cropland and creating widespread famine, mass extinction of species, hundreds of millions of climate refugees, world-wide economic depression, etc.?
The consensus of climate scientists is that we are currently headed toward these disastrous conditions well before the end of this century if we don’t drastically curb our carbon emissions now. (These changes will be effectively permanent, by the way.) The shift away from fossil fuels can be done — it is mostly a matter of public policy — and it must be done. It is not too late. Otherwise, an unknown percentage of our children and grandchildren will not survive this bleak future. Don’t take a chance with the lives of our loved ones. Chuck Sher
Brooklyn: It was great to see thousands of young people get together to call for attention and action about climate change. It will be great if they also ask their parents to stop buying SUVs, and to not cut down trees to make space to build vacation homes. Francisco J. Castillo
Fairfield, Conn.: Voicer Grace Fornatora believes that the “mantra of climate change is nothing but a cult started by lefty lunatics.” I wonder if she also believes the moon is made of cheese or that the Earth is flat. My advice? Turn off the TV and read a paper. Stephen Johnson
Brooklyn: I disagree with the Mets’ decision to retire Jerry Koosman’s number. He’s someone who has spent time in prison for tax evasion. That should be enough to sway the Mets from giving him this honor. Why is it that Pete Rose is not in the Baseball Hall of Fame while Koosman is honored? Rose did not commit any crimes. In addition, O.J. Simpson is still in the Pro Football Hall of Fame. What is wrong with this picture? Steve Yanowsky
Bronx: It’s over. Nancy Pelosi has just handed the 2020 election to Donald Trump. She has removed the element of choice and strategy from the eventual Democratic nominee at a time when we don’t know what the revelations from the Trump scare of the week will be, and captured the attention of a Republican electorate torn between bemoaning Trump for his stupidity and punishing Democrats for their wickedness. The decision becomes much more clear-cut now. Jorge Sierra
Rego Park: I don’t understand the urge for impeachment. The elections are not far off. If the citizens of our country want to end Trump’s presidency, let them do it on Election Day. That would be the will of the people, not of the politician phonies. Let the people decide! John Stanley Zach
Manhattan: America has always been a work in progress. While it has not always met the high ideals it aspires to, it is the only country ever founded upon the principles of freedom and liberty. From its start, America has steadily struggled to resolve the impediments to all Americans fully sharing in its promise. Today, the idea of America as a collaboration is being lost in the growing tribalism of identity politics. The American Dream is not a zero-sum game between warring groups, but a challenge for all to grow our shared dream together. We should recall the days following the 9/11 attacks when we came together as one people, one nation. America is not perfect, but it is the best country that ever existed. Joseph McCluskey
Pearl River, N.Y.: I’ve just realized, after some three years of a Trump administration, what the progressive movement is trying to do in this country. They are trying to change all the orthodoxies upon which this country has grown and prospered over the past two centuries, from the Constitution to the role of capitalism. Our history, in their eyes, has been one of oppression, racism and whatever other pejoratives comes to mind. Our whole way of life is a lie and must be corrected. Except, of course, in the case of the presidency. The highest office in the land and its traditions are sacrosanct and can never be altered or tampered with. Except when it isn’t. What is right and normal is what the progressives say is at the time they say it, and if that proves to be inconvenient or not expedient, well, they will change it, because they know better, and because they can. Thomas McNaughton
Kew Gardens Hills: Now that our part-time mayor has dropped out of the race for the White House, I am sure the other Democratic presidential candidates will fight tooth and nail for Bill de Blasio’s 0% of the Democratic electorate. Barry Koppel
Manhattan: Re “Why not give them real help” (Sept. 25): Real help? Can anyone explain to me why it is we allow people to come in and remain in the public shelter system without mandatory drug testing? It seems to me the sensible approach would be to provide drug treatment to those who require it — whether they want it or not — thereby freeing up a few thousand shelter beds for those with a legitimate need for them. Anyone not willing to meet the city halfway on this should be given the boot. Pronto! Aydin Torun
Commack, L.I..: Alec Schierenbeck’s op-ed (“End single-family zoning in NYC,” Sept. 18) neglects to mention the legitimate purpose of having single-family zoning restrictions in New York City, which is to curb growth in response to infrastructural limitations. Simply put, many single-family neighborhoods in the city lack the infrastructure or transit access to support the denser development many advocate for. As such, it’s up to policymakers and planners to ensure such zoning is used wisely, justifiably and fairly. Zoning is a tool, and its effectiveness is determined by the policymakers who wield it.
