Lyme disease was first identified in chilly Lyme, CT. Rocky Mountain Spotted Fever was first found in frigid Idaho & Montana. Both spread SOUTH — obviously NOT due to global WARMING.
Like every other climate scare, this one is a lie.
There's no evidence at all that climate change is spreading ticks and the diseases they carry, or any other disease. One degree of warming is equivalent to just 50-70 miles latitude change — completely trivial compared to tick ranges.

Here's a tweetstorm where you can learn many things about CO2 and climate that Grist and the rest of the Climate Industry will never tell you.
@zteirstein 4/18.
The climate scam needs to end. The renewable energy rollout is already killing many thousands of people through fuel poverty, and impoverishing millions more.
@zteirstein 5/18.
But that's just the tip of the iceberg. Where climate activists succeed in curtailing agriculture, to fight climate change, the human toll will be catastrophic — as it already has been in the Democratic Socialist Republic of Sri Lanka: un.int/srilanka/news/…
@zteirstein 6/18.
I've sadly concluded that most "climate journalists" don't really care what's true, nor who the climate industry's lies hurt. Do you?
If you're an exception, prove it by opening your mind, to learn about #ClimateChange from impartial scientists.
@zteirstein 8/18.
The supposed major harms from CO2 emissions are all merely hypothetical, and mostly implausible. None of them are actually happening.
For instance, the coral of the Great Barrier Reef are doing fine:
@zteirstein 9/18.
"Extreme weather" is not getting worse. Hurricanes, tornadoes, nor'easters, and droughts are not worsening. In fact, tornadoes & droughts have become much less destructive.
@zteirstein 10/18.
Droughts have showed only a slight decreasing trend, but they're MUCH less destructive now, because elevated CO2 levels make plants more water-efficient and drought-resilient.
@zteirstein 12/18.
The tide gauge at Harlingen has a continuous sea-level measurement record all the way back to 1865. Contrary to climate industry FUD, the sea-level trend has not been significantly affected by climate change. sealevel.info/learnmore.html…
@zteirstein 13/18.
All of the important effects of CO2 emissions and manmade climate change are positive!
Elevated CO2 (eCO2) is beneficial for almost all ecosystems. In fact, eCO2 even helps pine forests withstand bark beetles.
@zteirstein 14/18.
Elevated CO2 helps warm the Earth, but there's no convincing evidence that's harmful. In fact, scientists call the warmest climate periods "climate optimums."
@zteirstein 16/18.
The fact that elevated CO2 is extremely beneficial for agriculture has been known to science for >100 years. tinyurl.com/1920sciamCO2

Rising CO2 levels improve crop yields in two major ways: through "CO2 fertilization," and by improving drought resilience and water use efficiency (WUE). That's long-settled science, among agronomists.
Most plants utilize C3 photosynthesis, and agronomy studies show that for C3 crops the CO2 fertilization benefit is highly linear as CO2 levels rise, until above about 1000 ppmv (which is far higher than we could ever hope to drive outdoor CO2 levels by burning fossil fuels). That linearity is obvious in the green (C3) trace, in this graph:
Here's a study about wheat (a C3 crop):
Fitzgerald GJ, et al. (2016) Elevated atmospheric [CO2] can dramatically increase wheat yields in semi-arid environments and buffer against heat waves. Glob Chang Biol. 22(6):2269-84. doi:10.1111/gcb.13263.
Plants (and animals) are carbon-based lifeforms. Plants get the carbon they need from CO2 in the air; CO2 is, literally, plant food. The higher the CO2 level, the less air plants must process through their stomata, and the less water they lose in the process (transpiration).
Elevated CO2 improves plants' WUE and drought resilience by improving CO2 stomatal conductance relative to transpiration. So eCO2 is especially beneficial in arid regions, and especially beneficial for crops which are under drought stress.
Corn (maize) has been very heavily studied. Even though it is a C4 grass (and C4 plants are better at enduring low CO2 levels), corn benefits greatly from elevated CO2, especially under drought stress. Here's a paper:
Chun et al. (2011). Effect of elevated carbon dioxide and water stress on gas exchange and water use efficiency in corn. Agric For Meteorol 151(3), pp 378-384, ISSN 0168-1923. doi:10.1016/j.agrformet.2010.11.015.
EXCERPT: "There have been many studies on the interaction of CO2 and water on plant growth. Under elevated CO2, less water is used to produce each unit of dry matter by reducing stomatal conductance."
That improvement is one of several major reasons that catastrophic drought-triggered famines are fading from living memory, for the first time in history.
If you're too young to remember huge, devastating, drought-triggered famines, count yourself blessed. Through all of human history, until very recently, famine was one of the great scourges of mankind, the Third Horseman of the Apocalypse. But no more. That is a miracle!
Here's the data:
Ending famine is a VERY Big Deal, comparable to ending war and disease. Compare:
● Covid-19 killed 0.1% of world population.
● 1918 flu pandemic killed about 2%.
● WWII killed 2.7%.
● The near-global drought and famine of 1876-78 killed about 3.7% of the world population.

2/5》 If we got at most 0.92°C of warming from 58% of the forcing of a full doubling of CO2, then (at most) how much warming we could get from a full doubling of CO2?
3/5》 Those figures are very conventional estimates, widely accepted by climate alarmists. Yet those same climate alarmists believe that TCR climate sensitivity is 1.5 to 2.0°C/doubling of CO2, and ECS is about 3.0°C/doubling of CO2.
1/10. Where on earth do you "learn" such nonsense, Willard?
Growing ranges for most major crops cover climate zones with average temperatures that vary by tens of °C. Major crops like corn, wheat, potatoes & soybeans are produced from Mexico to Canada.
Compared to that, a degree or two of warming (disproportionately at night, in winter, at chilly high latitudes) is de minimis -- as is the 0.35±0.13°C between now and what the IPCC calls "1.5°C of warming").
2/10. Willard wrote, "fertilization is the male gamete to female gamete to produce seed/fruit... not the N-P-K addition"
Wrong. In agriculture, that's called pollination.
3/10. Willard wrote, "(yes, it is often temperature sensitive)"
Wrong. Farmers choose planting dates to optimize growing conditions, including temperatures, for their crops.
1/7. The only trace on that graph which does not show large improvement in cereal yield per hectare is the trace for Niger.
The graph ended with an anomalously bad crop year for cereals in Niger (2021). Fortunately, 2022 was much better; here's an article worldbank.org/en/news/press-…
2/7. By displaying high productivity countries like the USA along with Niger, you forced OurWorldInData to scale the graphs so that it's hard to see the trend in Niger.
But if you display Niger alone, as I've done here, you'll see that cereal yields declined there until about thirty years ago, but they've improved since then (except for 2021).
As you can see, as atmospheric CO2 levels have risen, the natural CO2 removal rate has sharply accelerated. (That's a strong negative/stabilizing climate feedback.) sealevel.info/AR6_WG1_Table_…
BBanana wrote, "Temperature increases have already reduced global yields of major crops."
That's false. It's long been known that warming generally improves agricultural productivity. Here's a CIA study which summarized the relation:
2/10. Fig.7 from that study shows the number of people who could be supported per hectare of arable land, vs. temperature. The 7 curves represent varying precipitation rates. In each case, higher temperatures allow the support of higher populations, due to better crop yields.
3/10. Also, elevated CO2 directly improves crop yields, and mitigates drought impacts. That's helping make famines rare for first time in history.
Those too young to grok how revolutionary that is should count themselves blessed! Famine used to be a scourge comparable to war & disease.
