Quick, someone needs to let this volcano know it's in violation of the Paris accord!

Seriously, volcanic ash from a major eruption far outpaces human contributions. Remember 1815, the year without a summer? Mount Tambora erupted and caused a volcanic winter that led to famine. In 1883 Krakatoa caused a drop in temperatures on the average of 2.2 * F / 1.2* C, again impacting food supply chains with shortages. Volcanic winters have long been associated with the term "little Ice Age". I know God has a plan and He's in control. Why worry?

Peak heat stress, quantified by the wet-bulb temperature TW, is surprisingly similar across diverse climates today. TW never exceeds 31 °C. Any exceedence of 35 °C for extended periods should induce hyperthermia in humans and other mammals, as dissipation of metabolic heat becomes impossible. While this never happens now, it would begin to occur with global-mean warming of about 7 °C, calling the habitability of some regions into question.

35 C is 95 F. I would work most the day in 100 F. I question this hypothesis.

They are talking wet-bulb temps, not dry bulb, which is what I assume you are referring to. At 50% humidity, a 115 F dry bulb temp converts to about a 96 F wet bulb temp at sea level. If humidity drops to 20%, the equivalent dry bulb temp is 140 F.

It also sayd a mean warming of 7 C would begin an issue. This is a far jump from the 2 C raise by 2100.

The 35 °C is the wet-bulb temperature that is dangerous. This means the temperature with evaporative cooling on the bulb of the thermometer. At 30% humidity at 100°F has a wet bulb temperature of about 75°F. This chart may help:
It is the heat waves that may become more severe and frequent that endanger human life.

Humans emit 100 times more C02 than volcanoes.

Sigh

You mean now I have to worry about whether my bulbs are wet or dry as well? I just cannot keep up.

After 30 Years, Alarmists Are Still Predicting A Global Warming ‘Apocalypse’

Here's a good discussion on how data compares to past predictions. It also discusses how predictions made by climate contrarians have fared. For instance, here is sea level rise:



This video is under 2 minutes, it compares the predictions of the main models to later observations.

Here is a 10 minute video that goes into more depth on climate models and how we measure the accuracy of their predictions. It discusses what they measure well and where their limitations are.

Plant your bulbs, give them some moisture, don't let them dry out and they should grow. I know some people talk to their plants but it might be better not to since that will just create more of that harmful CO2. Maybe the young people have a good thing going by communicating by text instead of talking to each other - they are being green.

While scientists are still deciphering if particular heat waves, such as the ones in Pakistan and India, could be tied to climate change, it is accepted science that heat waves, broadly speaking, will become more frequent, intense and prolonged with global warming.

So they still do not know if they are tied to it, but warn that it will cause massive deaths if it goes to 7 C higher mean, which the IPCC projects a max of 3 C raise by 2100.

I see sensationalism.

Again, I grew up and worked in factories without A/C in Texas. We had 100 F days for 30-90 days in a row. We got the humidity off the Gulf Coast and it would be 90%+ some of those days. We still played basketball during lunch outside. After we were done, we would stand in front of a fan for a about 2 minutes, but after that, back to work.

Your source is skepticalscience.com which is not a peer reviewed journal but rather a global climate alarmist site, it is run by John Cook, who is not a climate scientist.

Oh Robert you just do not get it. The bulbs in those factories were simply too wet. Or maybe, was it that they were dry and should of been wetter? Oh my, I am so confused. MONDAY MORNINGS DO THAT TO ME.
