I live in a city that does not have great transportation options, and I live far enough from my work that I am not able to walk or ride a bike. I have a 15-year-old car that I am looking to replace.

New York state prosecutors last week accused ExxonMobil of trying to discourage witnesses from testifying against the company in a climate fraud case, leading the head of the environmental group 350.org to declare Thursday that "we won't be intimidated."
There's no shortage of CBD products on the market today, especially when it comes to CBD oils. These tinctures are the most popular way to take CBD, but there is so much variety amongst CBD oils it can be hard to know which one is the right choice for you. Among the different flavor options, CBD strengths, and types of hemp extracts (like full-spectrum CBD oil vs CBD isolate), there is another potential differentiator when it comes to CBD oil: water solubility.

What's for breakfast? Maybe it's a bagel and cream cheese, or toast and coffee, or eggs (or not). For millions of Americans, though, cereal is a breakfast mainstay. There's a mind-boggling array of ready-to-eat cereal brands on offer, and everyone has their favorites.

Last week, UCS released Killer Heat, a report analyzing how the frequency of days with a dangerously hot heat index — the combination of temperature and humidity the National Weather Service calls the "feels like" temperature — will change in response to the global emissions choices we make in the coming decades.
Calls for Radical Climate Action Grow Louder as NOAA Reports Last Month Was Hottest June Ever Recorded
By Jessica Corbett
As meteorologists warned Thursday that temperatures above 100°F are expected to impact two-thirds of the country this weekend, U.S. government scientists revealed that last month was the hottest June ever recorded — bolstering calls for radical global action on the climate emergency.

Because extreme heat is one of the deadliest weather hazards we currently face, Union of Concerned Scientist's Killer Heat Report for the U.S. is the most important document I have read. It is a veritable wake up call for all of us. It is timely, eye-opening, transparent and factual and it deals with the stark reality of our future if we do not make changes quickly (think yesterday). It is important to ensure that we all understand it. Here are 10 terms that really help drive home the messages in the heat report and help us understand the ramifications of inaction.
Weather vs Climate<p>One of my four brothers <em>loves</em> to cook – and he is great at it. One day I made the mistake of calling him a cook. He quickly corrected me by saying: "Cooking is what I do, a Chef is what I am." See the difference there? It is the same with weather and climate. In <a href="https://www.geog.ox.ac.uk/news/articles/150731-remembering-herbertson.html" target="_blank">Andrew John Herbertson's</a> words: "Climate is what you expect. Weather is what you get." You expect it to be hot this summer season but what you really get is a <a href="https://streamable.com/y5j8i" target="_blank">heat wave</a>.</p>
Global Warming and Climate Change<p>Global warming is a long-term increase in the Earth's annual average surface temperature, caused mainly by increased fossil fuel emissions. So — when the Earth heats up over time, it is <a href="https://streamable.com/f7v1n" target="_blank">global warming</a>. Climate change, on the other hand, refers to a change in the climate system of the Earth, including its weather patterns.</p><p>Current climate change is mostly caused by the fossil fuel emissions that increase atmospheric concentration of carbon dioxide. A host of changes flow from this: ocean acidification, global mean surface temperature increase (aka 'global warming'), shrinking glaciers in the Arctic, Antarctica, Greenland and mountain glaciers, sea level rise, changes in flower blooms, animal and plant distribution shifts, and changes in frequency and intensity of extreme weather events.</p><p>There should never be a time that, when the temperatures are really low, we wish for "global warming" so that the temperatures will increase — Ever. Because there will always be winters. However, the problem is that winters around the globe are getting warmer, on average — even if northern hemisphere winters have periodic extreme cold snaps in places, such as what occurs when the Arctic air blasts to lower latitudes in parts and warmer air shifts more northward at other parts with a <a href="https://royalsocietypublishing.org/doi/full/10.1098/rsta.2014.0170" target="_blank">wavier jet stream at times</a>.</p>
Temperature and the Heat Index<p>The heat index is slightly different from the temperature, although temperature is used to calculate it. Temperature is what we can measure in the thermometer. But the heat index is what we feel that temperature to be when we factor in relative humidity. That is why the <a href="https://www.weather.gov/safety/heat-index" target="_blank">National Weather Service calls the heat index the "feels like" temperature</a>. For example, in Mobile, Alabama where I grew up, the thermometer might register 80°F outside, but because of humidity and other factors it can feel like a temperature of <a href="https://streamable.com/edit/4t04h" target="_blank">100°F</a>!</p>
The Urban Heat Island (UHI)<p>When I was in graduate school in Tennessee, the air conditioner in my apartment did not really work well. So, I would sit directly in front of the fan — DIRECTLY. If I stuck an arm or leg outside of my "fan zone" I would immediately be assaulted by what I can only equate to the infamous <a href="https://streamable.com/wsjsv" target="_blank">'Heat Miser' from Rudolph the Red-Nosed Reindeer</a>.</p><p>Outside of that zone, the heat showed no mercy and my body's response was first shock, then intense sweat. I think of the <a href="https://www.nationalgeographic.org/encyclopedia/urban-heat-island/" target="_blank">Urban Heat Island</a> in a similar way, except that there are no "fan zones" and very few mechanisms for relief from the heat for at-risk populations.</p><p>The UHI occurs because cities are much warmer than surrounding rural areas — cities resemble an "island" of heat among a broader "sea" of cooler temperatures. Concrete, glass, asphalt, and other surfaces that make up cities trap heat during the day and then release it at night, but it escapes much slower than it was trapped, so there is not much relief from the heat!</p><p>Temperatures do drop a little at night, so people can open their windows and doors or sit outside to get some relief. Can you imagine what it is like for our homeless brothers and sisters or people without adequate air conditioning, or whose electric bills are so high that they can not afford to turn on their fans or air conditioners? What about people whose work requires them to spend a lot of time outside, or children who play outside the majority of the time? Think about that…</p>
Heat Cramps, Heat Exhaustion and Heat Stroke<p>When I was growing up in Mobile, Alabama, my Mom would tell my brothers and me to be careful outside when it was hot — that we could have a "heat stroke." (She also used to say that we smelled like "the sun," whatever that meant, when we came inside after playing outdoors so I suspect that she just did not want us to get too sweaty.)</p><p>Luckily, none of us ever had serious complications from <a href="https://streamable.com/qfe4z" target="_blank">heat</a>. But prolonged exposure to extreme heat can cause <a href="https://www.osha.gov/SLTC/heatstress/heat_illnesses.html" target="_blank">heat cramps, heat exhaustion, or heat stroke</a>.</p><p>Heat cramps, caused by the loss of body salts and fluids during sweating, can be painful.</p><p>Heat exhaustion is how the body responds to loss of water and fluids from heavy sweating; symptoms include headaches, nausea, dizziness, weakness, thirst and heavy sweating.</p><p>The most serious is heat stroke, which happens when the body gets so hot it cannot regulate its core temperature. People going into a heat stroke stop sweating, so their bodies cannot get rid of the excess heat, which could cause confusion, loss of consciousness, and seizures.</p><p>Heat strokes are a serious medical emergency that can result in death. Under a changing climate, the likelihood of dangerous heat-related health risks increasing is all too real. Sadly, if my Mom were to issue that "<a href="https://www.cdc.gov/disasters/extremeheat/warning.html" target="_blank">heat stroke</a>" warning under the current and future conditions, she would probably be right.</p>
Representative Concentration Pathways (RCPs)<p>RCPs are future emissions scenarios used to model the choices that we can make about carbon emissions. RCP8.5 refers to a "no action" scenario where no substantial reductions in emissions are pursued through the late century. RCP4.5 is the "slow action" scenario, under which emissions start to decline around mid-century. In addition, with the "rapid action" scenario, future global warming, even by late century, is limited to 2ºC above pre-industrial temperatures. Achieving this would require rapid reductions in emissions over the next few decades.</p><p>RCPs make assumptions about how carbon emissions in the atmosphere will change in the future as a result of human activities. In other words, think of it as an "if this occurs, then this will happen" scenario for <a href="https://streamable.com/wnly7" target="_blank">global warming</a>.</p><p>The more immediate and impactful actions we take now, the greater our chances are of avoiding KILLER HEAT conditions, serious adverse health outcomes and the worst consequences of climate change — especially on our most at-risk populations.</p>

Solar geoengineering describes a set of approaches that would reflect sunlight to cool the planet. The most prevalent of these approaches entails mimicking volcanic eruptions by releasing aerosols (tiny particles) into the upper atmosphere to reduce global temperatures — a method that comes with immense uncertainty and risk. We don't yet know how it will affect regional weather patterns, and in turn its geopolitical consequences. One way we can attempt to understand potential outcomes is through models.
