Fact A: There is more CO2 in our atmosphere today than last year, and the year before that, and the year before that. 
  
Fact B: What happens when you put more CO2 in to our atmosphere? It heats up.

Global temperatures have undeniably risen, and to claim otherwise is to ignore overwhelming scientific data. According to the NOAA Annual Global Climate Report (2021), the combined land and ocean temperature has increased at an average rate of 0.18°C (0.32°F) per decade since 1981. As of 2020, global temperatures were 1.02°C (1.84°F) above the 20th-century average, with 2020 being one of the hottest years on record, just behind 2016. The years 2015-2020 all rank among the six hottest years since records began in 1880.
   
Furthermore, Greenland and Antarctica are losing ice at an accelerating pace. The Greenland Ice Sheet is losing about 286 gigatons of ice per year, which alone accounts for a sea-level rise of 0.77 mm per year. A study published in Nature in 2020 shows that Greenland lost 3.8 trillion tons of ice between 1992 and 2018, while Antarctica lost 2.5 trillion tons during the same period. The Antarctic Ice Sheet is losing ice at a rate of 148 gigatons per year, contributing to a global sea level rise of approximately 0.4 mm per year.  This data is corroborated by NASA’s GRACE (Gravity Recovery and Climate Experiment) satellites, which provide consistent evidence of ice loss. The IPCC (Intergovernmental Panel on Climate Change) also projects that if emissions continue at their current pace, global sea levels could rise by 0.61 to 1.10 meters by 2100.  According to the IPCC Special Report on Extreme Events (2019), the frequency of heavy precipitation events has increased significantly in most regions of the world. For every 1°C rise in global temperature, the atmosphere can hold about 7% more water vapor. This increase in moisture leads to heavier rainfall during storms. For example, the 2017 Hurricane Harvey dumped 50 inches of rain over parts of Texas, making it the wettest hurricane on record in the U.S., with its intensity amplified by warmer sea surface temperatures. Harvey caused $125 billion in damages, according to the National Hurricane Center.
   
Furthermore, heatwaves are now more frequent and severe. A 2018 study published in Environmental Research Letters shows that Europe has experienced a twofold increase in the frequency of heatwaves since 1950. The 2019 European heatwave broke temperature records across multiple countries, with France hitting an all-time high of 45.9°C (114.6°F). A 2020 World Weather Attribution study linked this directly to climate change, estimating that human activity made the heatwave at least five times more likely.
   
Your false claim that extreme weather events, including hurricanes, are declining is factually incorrect. According to the NOAA National Centers for Environmental Information (NCEI), 2020 was the most active Atlantic hurricane season on record, with 30 named storms, including 12 that made landfall in the continental U.S.. This broke the previous record of 28 storms in 2005. The intensity of hurricanes has also increased. A study published in PNAS (Proceedings of the National Academy of Sciences) in 2020 shows that the proportion of Category 4 and 5 hurricanes has increased by 25-30% over the past 40 years due to rising sea surface temperatures, fueled by climate change. A separate study in Nature Communications found that between 1979 and 2017, tropical cyclones globally slowed by 10%, which means they linger longer over land, causing more damage. For example, Hurricane Harvey in 2017 stalled over Texas for several days, dumping unprecedented amounts of rainfall.
   
While it’s true that we have more comprehensive data collection in the modern era, that doesn't change the reality of long-term trends; in fact, historical data is required when evaluating climates. Data collection improvements have allowed for greater accuracy in comparing past and present conditions, but scientists use standardized methods to adjust for differences in historical data. The idea that modern data collection somehow inflates the observed trends in climate change is misleading.  For example, NOAA’s Climate Extremes Index (CEI), which tracks the frequency of extreme weather events in the U.S., shows a significant upward trend since 1910. The Global Climate Extremes Index (GCEI), which covers global weather extremes, reports that the combined frequency of extreme heat, drought, and precipitation events has risen by about 50% over the past century. These figures are consistent with both historical and modern data collection methods.
   
The claim that "CO2 emissions do not cause climate change" is in direct opposition to the overwhelming consensus of climate scientists. CO2 is a well-documented greenhouse gas, and its role in trapping heat in the Earth’s atmosphere has been understood since the late 19th century. The Keeling Curve, a measure of atmospheric CO2 concentration, shows a clear increase from 315 parts per million (ppm) in 1958 to over 420 ppm today.  Studies published in leading journals like Nature and Science have repeatedly confirmed that CO2 is the primary driver of recent global warming. A 2014 study published in Environmental Research Letters analyzed over 11,000 peer-reviewed scientific papers on climate change and found that 97% of climate scientists agree that human activities, particularly the burning of fossil fuels, are responsible for recent warming trends. Moreover, according to the IPCC Fifth Assessment Report, human activity is responsible for more than 95% of the observed warming since 1950. The CO2 increase is directly linked to the enhanced greenhouse effect, which traps more heat in the atmosphere, resulting in rising global temperatures.
   
The weak argument that climate change is "unfalsifiable" misunderstands how science works. Climate change is a falsifiable hypothesis that has been tested and confirmed by multiple independent lines of evidence. Climate models, for example, make predictions about how temperatures, sea levels, and weather patterns will change in response to increasing greenhouse gases. These predictions are then tested against real-world observations. For instance, climate models predicted that polar amplification (the phenomenon where the Arctic warms faster than the rest of the planet) would occur as a result of rising CO2 levels. Observations over the past few decades have confirmed this prediction, with the Arctic warming at roughly twice the rate of the global average. Moreover, regional differences in the effects of climate change (e.g., more rainfall in some areas, less in others) do not make the science unfalsifiable—they are predicted outcomes based on the complexity of the Earth’s climate system. The IPCC’s Fifth Assessment Report clearly outlines how different regions will experience different climate impacts due to varying geographic and atmospheric conditions. This variability is a known and expected outcome of global climate change.
     
To summarize, your claims about global temperatures, extreme weather, CO2 emissions, and the nature of climate science are not supported by the evidence. Global temperatures have risen significantly, ice sheets are melting at an accelerating pace, and the intensity and frequency of extreme weather events, including hurricanes and heatwaves, are increasing. CO2 emissions are the primary driver of recent climate change, as confirmed by thousands of scientific studies. Finally, climate science is based on testable hypotheses that are continually validated by real-world data.
   
By ignoring this evidence, you’re dismissing the vast body of scientific research that supports these conclusions. Dismissing these trends is not just a rejection of climate science; it’s a rejection of empirical evidence.
