The importance of continually adjusting our understanding of Climate Change

Image
Both the Intergovernmental Panel on Climate Change’s (IPCC) and the National Climate Assessment’s (NCA) reports provide continual corrections to our understanding of  Climate Change . Our quickly warming planet is undergoing vast changes that would be harder to ‘see’ if we didn’t have reports like these: FOURTH NATIONAL CLIMATE ASSESSMENT Volume II: Impacts, Risks, and Adaptation in the United States  The National Climate Assessment (NCA) assesses the science of climate change and variability and its impacts across the United States, now and throughout this century. "Earth’s climate is now changing faster than at any point in the history of modern civilization, primarily as a result of human activities. The impacts of global climate change are already being felt in the United States and are projected to intensify in the future—but the severity of future impacts will depend largely on actions taken to reduce greenhouse gas emissions and to adapt to the chang...

Don’t bury the NCR4 Volume II on Climate Change in the US

Image
In what might be a craven diversionary tack to bury the release of the National Climate Assessment (NCA) Volume II on Black Friday, Trump tweeted on November 21 st “Brutal and Extended Cold Blast could shatter ALL RECORDS - Whatever happened to Global Warming?” 'Absolute Disgrace': When No One Looking, White House Plans to Dump Major Climate Report on Black Friday The administration just announced Wednesday that the National Climate Assessment Volume II would be released Friday afternoon Environmental groups, journalists, and climate scientists are reacting to the Trump administration's decision to release a major climate report the day after Thanksgiving—a move some are describing as an effort to bury an assessment packed with an "astonishing amount of science," and they are hoping to see that effort backfire "bigly." "It's an absolute disgrace to bury the truth about climate impacts in a year that saw hundreds of Americans die during devast...

Do we have the will for the societal transformation needed to limit global warming to 1.5°C.?

Image
Sustainable development supports, and often enables, the fundamental societal and systems transitions and transformations that help limit global warming to 1.5°C. Such changes facilitate the pursuit of climate-resilient development pathways that achieve ambitious mitigation and adaptation in conjunction with poverty eradication and efforts to reduce inequalities (high confidence). {Box 1.1, 1.4.3, Figure 5.1, 5.5.3, Box 5.3} (Page 24, IPCC, 2018: Summary for Policymakers . In: Global warming of 1.5°C.

Addressing Climate Change after the US midterms

Image
The results of the US midterm elections, with the Democrats retaking the House and some governorships, are a victory in the sense that our country avoided falling into the abyss—a horrible place where our economics, our humanitarian values, and our politics run amuck. Supposedly, there will now be checks on Trump, his administration, and the GOP’s attempts to undermine our environmental health while trying to erase Climate Change from our nation’s responsibilities: With Democratic Majority, Climate Change Is Back on U.S. House Agenda  Fossil fuel supporters will still control the Senate, but the House will soon be able to turn a spotlight on climate change and Trump's retreat from responsibility. With their win of control of the U.S. House of Representatives, Democrats will now have the numbers to put climate change issues back on the congressional agenda. But the Republicans reinforced their firewall against any legislative efforts in the Senate by gaining at least two new m...

What our youth know about Climate Change

Image
It is hard to understand why those who deny Climate Change haven’t at least explored how this crisis will affect their kids. Because if they had, we’d all be making the necessary changes to protect our children. We know what to do, we just need the will to do it. Kids’ Health and Climate Change  Our changing environment—caused by carbon pollution from coal, oil, and gas—is already affecting children’s health and changing how they grow up. Many people are familiar with climate change impacts like flooding and sea-level rise, but rising temperatures and decreased air quality are already affecting kids: Increasing asthma attacks and allergies; Creating food insecurity; Mental health problems; Developmental delays; and Changes in their genetic makeup. Kids are not little adults. Their health is impacted more by climate change. Children’s immune systems and organs are still developing, and they eat and drink more for their size. They also breathe at a faster rate, increasing their expos...

Planning for Earth Day 2019 in Rochester, NY

Image
For about twenty years, the Rochester Regional Group of the Sierra Club ’s Earth Day forum has been a yearly opportunity to engage with the public on environmental issues. We’ve hosted local and state public officials responsible for our environment, local reporters, prominent speakers on protecting our Great Lake’s waters, and other issues like local food options. Our most attended forum was when Dr. Hansen talked to about 800 people on April 21. 2015 at Monroe County Community College. [Watch the entire speech, with an introduction by Dr. Susan Spencer. Very high-quality  video .] Clearly, who we invite to speak makes a difference. But we only have so many recourses at our disposal. Each year we try to figure out the most important environmental issue that is most likely to attract a large audience. (What’s the point of trying to communicate with the public, if they don’t show up?) I’ve been writing about the journey to Earth Day each year for quite a while, trying to build mome...

Climate Change choices for your consideration

Image
If it’s true that we are merely consumers (as some view our existence), and not the moral stewards of our planet, then consider humanity’s Climate Change options for our future. There are several climate scenarios to choose from—depending on your taste for disruption. Your choices are, as brilliantly and illustrated in this interactive chart, 1.5C, 2C, and beyond: The impacts of climate change at 1.5C, 2C and beyond  "Carbon Brief has extracted data from around 70 peer-reviewed climate studies to show how global warming is projected to affect the world and its regions. "  Scrolling through the above list is fascinating, like strolling up and down aisles in a grocery store. For example, do you want a 1.5C world where winter minimum temperatures in France will rise .09C? Or maybe a 3C world where rainfall will increase by 21% in Eastern Europe? Lots to choose from. But there’s a catch, actually many of them. First, costs vary considerably with your choices not only by dollars a...
