Air pollution causes around 7 or 8 million deaths each year. [ 5 ] [ 6 ] It is a significant risk factor for a number of pollution-related diseases , including heart disease , stroke , chronic obstructive pulmonary disease (COPD), asthma and lung cancer .
The authors estimated that climate change was projected to cause an additional 250,000 deaths per year between 2030 and 2050 but also stated that "these numbers do not represent a prediction of the overall impacts of climate change on health, since we could not quantify several important causal pathways".

Diseases caused by pollution, lead to the chronic illness and deaths of about 8.4 million people each year. However, pollution receives a fraction of the interest from the global community. [1] This is in part because pollution causes so many diseases that it is often difficult to draw a straight line between cause and effect.
Environmental epidemiology is a branch of epidemiology concerned with determining how environmental exposures impact human health. [1] This field seeks to understand how various external risk factors may predispose to or protect against disease, illness, injury, developmental abnormalities, or death.
In 2016, the WHO recorded 56.7 million deaths [3] with the leading cause of death as cardiovascular disease causing more than 17 million deaths (about 31% of the total) as shown in the chart to the side. In 2021, there were approx. 68 million deaths worldwide, as per WHO report.
Climate change is fueling tinderbox conditions that spark increasingly severe wildfires, resulting in thousands of deaths related to their smoke Smoke pollution from wildfires is causing an extra ...
The risk of heat-related death increases with age. With no additional adaptation and limited global decarbonisation, heat-related deaths could increase nearly 6-fold from an estimated average of 1,602 deaths per year in the 2007-2018 period to 10,889 deaths per year in the 2050s. [6]
The sharp acceleration in CO 2 emissions since 2000 to more than a 3% increase per year (more than 2 ppm per year) from 1.1% per year during the 1990s is attributable to the lapse of formerly declining trends in carbon intensity of both developing and developed nations. China was responsible for most of global growth in emissions during this ...
