Perhaps so, but, it is still all Man’s fault
Next week, August 15 to be exact, is the opening of ragweed season.
That’s bad news for the 36 million Americans who suffer from ragweed allergy– and global warming could be making things worse.
In a new review, scientists reporting in the Journal of Allergy and Clinical Immunology describe multiple ways in which warmer temperatures impact our health. One study found that plants flower an average of nearly five days earlier now compared to a decade ago.
Carbon dioxide gas is linked to a 60 to 90 percent rise in pollen production for some ragweed varieties and global warming is also expected to create more forest fires that trigger air pollution that worsens asthma.
In other words, let’s reduce the amount of CO2 and kill off all the plants. Too bad the global climate temperature gradient has been stagnent for around 10 years now, despite the increase in CO2.

When you start with a year (1998) of unusually high temperatures due to El Nino your bound to get a false impression.
Climate scientists acknowledge that dips and spikes in temperature from year to year are driven more by natural factors (El Nino, volcanic eruptions like Pinatubo, etc.) than by anthropogenic greenhouse gases, and that the long-term warming trend is primarily driven by human emissions.

If natural processes are causing the long-term warming trend, which ones are they and what is your evidence? Why do you keep dodging this question?
