Evidence-Based Science: What We Want, Why It Matters

The What do we want? Evidence-Based Science T-shirt is a popular item of clothing for those who support the use of evidence and data in science. The shirt is often described as a funny or sarcastic item, perfect for scientists, teachers, or activists. It is also marketed as a gift for those in science-themed college majors. The shirt is usually made from a mix of cotton and polyester, with some varieties made from organic cotton.

Science is not a liberal conspiracy

The T-shirts are also a way to show support for scientists and science itself, which have come under attack by certain administrations. Climate change is real, and science is real. This is a statement that should not be controversial, but unfortunately, it is. Science is not a matter of opinion, and it is not a conspiracy. It is a method of seeking knowledge through observation and experimentation. It is a way of better understanding the world around us and making informed decisions.

The T-shirts are a fun way to show support for science and to spread the message that science is not a liberal conspiracy. They are also a reminder that we should demand evidence and think critically. We should not accept alternative facts or conspiracy theories. We should trust in the scientific method and the power of peer review.

So, let's stand up for science and show that we want evidence-based science! But when do we want it? After peer review!

Climate change is real

The Intergovernmental Panel on Climate Change (IPCC) has concluded that the influence of human activity on the warming of the climate system has progressed from a theory to an established fact since systematic scientific assessments began in the 1970s. Scientific data collected from natural sources, such as ice cores, rocks, and tree rings, as well as modern equipment, including satellites and instruments, all provide clear indications of a changing climate.

One of the most compelling pieces of evidence is the increase in global temperature. The planet's average surface temperature has risen by about 2°F (1°C) since the late 19th century, with the majority of this increase occurring in the past 40 years. The seven most recent years have been the warmest on record, and the years 2016 and 2020 are tied for the warmest year.

In addition to rising temperatures, there are multiple other signs of climate change:

• The ocean is absorbing much of the excess heat, with the top 100 meters showing warming of 0.67°F (0.33°C) since 1969.
• Ice sheets in Greenland and Antarctica are shrinking, with Greenland losing an average of 279 billion tons of ice per year between 1993 and 2019, and Antarctica losing about 148 billion tons per year.
• Glaciers are retreating almost everywhere, including in the Alps, Himalayas, Andes, Rockies, Alaska, and Africa.
• Snow cover in the Northern Hemisphere is decreasing, and snow is melting earlier in the spring.
• Global sea levels have risen by about 8 inches in the last century, with the rate in the last two decades nearly double that of the previous century and continuing to accelerate.
• Arctic sea ice is declining in both extent and thickness.
• Extreme weather events, such as record-high temperatures and intense rainfall, are becoming more frequent.
• The oceans are experiencing increased acidification due to the absorption of excess carbon dioxide.

These changes are already having significant impacts on the planet, including the displacement of marine life, bleaching of coral reefs, and severe consequences for fisheries and aquacultures.

The weight of evidence from various fields of science overwhelmingly confirms that climate change is a reality and that urgent action is needed to address this global challenge.

Science is real

The scientific method involves asking questions, conducting experiments, analyzing data, and drawing conclusions. This process is fundamental to the advancement of human knowledge and understanding of the world around us. It is a way to seek truth and knowledge through rigorous investigation and testing.

Evidence-based science is the foundation of many fields, including chemistry, biology, physics, and astronomy. Scientists in these fields make discoveries and develop technologies that benefit humanity and expand our understanding of the universe. For example, through scientific inquiry, we have learned about the existence and properties of atoms, molecules, and cells. We have discovered laws of physics that allow us to build machines and explore space. We have also gained a deeper understanding of our planet's climate and the impact of human activities on it.

Science is a tool that helps us make informed decisions and create a better world for future generations. It is essential to support and trust the scientific process, ensuring that our choices and actions are based on evidence and rational thinking. By demanding evidence and thinking critically, we can make informed decisions and challenge misinformation.

So, let's stand up for science and continue seeking knowledge and truth through evidence-based inquiry.

Science is greater than opinion

The t-shirts are usually made from a mix of cotton and polyester, with some being lightweight and having a classic fit. They are available in a variety of sizes and colours, and some are even made from organic cotton and printed with vegan-friendly ink. The phrase "What do we want? Evidence-Based Science! When do we want it? After Peer Review!" is often featured on the t-shirts, with some even having a stylised version of the word "science".

These t-shirts are a fun and unique way to show support for science and demand evidence-based practices and policies. They are perfect for anyone who wants to add a bit of humour and personality to their wardrobe while also advocating for a serious and important cause.

Science is fact

The scientific method is a crucial tool for scientists. It involves making observations, asking questions, and testing hypotheses through experiments. This process is iterative, meaning that scientists repeat it again and again to gather more data and refine their understanding. This method has been used to develop life-saving vaccines and treatments for diseases, to create new technologies that improve our lives, and to better understand the world around us, from the tiniest particles to the vast universe.

Evidence is at the heart of science. Scientists gather and analyze data to test their hypotheses and draw conclusions. This evidence is then scrutinized through a process called peer review, where other scientists in the same field evaluate the methods, data, and conclusions to ensure accuracy and identify any potential biases or flaws. This process helps to ensure the integrity of scientific research and builds a body of knowledge that is supported by multiple lines of evidence.

Science is also self-correcting. As new evidence emerges, scientists re-evaluate their theories and adjust their understanding accordingly. This constant quest for knowledge and understanding is what drives scientific progress and innovation. It is important to remember that science is not infallible, and it can take time to reach a consensus on certain topics. However, the strength of the scientific method lies in its ability to correct itself and build a more accurate understanding over time.

Science is a powerful tool for understanding our world and making informed decisions. By demanding evidence, thinking critically, and following the scientific method, we can make discoveries, innovate, and create a better future for ourselves and generations to come.
